Patching Vinyl Ester Floors With Novolac

July 28, 2016

A customer writes:

“We have a dairy processing and packaging facility that was built circa 1994.  At the time of construction we chose to install a flooring system which was vinyl ester based with fiberglass mat.  The floor has held up quite well in areas where it had a good bond.  The failures we have seen are in areas that covered either an expansion joint or control joint in the concrete.  In these areas the flooring has delaminated from the concrete.  Where possible we have made a clean cut through the flooring to an area where we had a good bond and left the concrete exposed.  Other failure areas are around floor drains.  We have made repairs with quick curing epoxies in the past but these don’t seem to bond well to the existing vinyl ester flooring. 

“Having a manufacturing facility with only one down day limits our ability to make substantive repairs.  During a search for low or no VOC  flooring systems I you folks.”

I have personally made many thousands of square feet of floor repairs that sounds exactly like the issues and conditions that you are describing.

Here is what I did to permanently resolve the issue, at least in the patched areas.

  1. Cut back the edges of the delaminated areas back to a point where the vinyl ester is well attached.
  2. Prep the concrete under the failed area and the edges of the old material – epoxy.com/surfaceprep.aspx.
  3. Prime with Epoxy.com Product #12 – epoxy.com/12.aspx
  4. Install a trowel coat of Epoxy.com Product #630 – epoxy.com/633.aspx and
    1. Epoxy Mortar Blend aggregate #82 Mortar Blend Aggregate
    2. Allow to cure hard to the touch and cool.
  5. Glaze with a neat coat of Epoxy.com Product #633 with optional Anti-skid – http://epoxy.com/non-skid-additive-polycarbonate-aggregate.aspx

Monument Repairs with Epoxy

March 9, 2016

A technician who uses a non-Epoxy.com product to repair tombstones wrote me recently looking for help with problems that he was having. He goes on to say that the epoxy that he uses never fails, but rather the stone fails. When a secondary break occurs, the stone always re-breaks about 2 mm (about ¾ inch) above or below the epoxy joint. The epoxy attached to about 2 mm of the stone and holds well.

He asked me if the epoxy shrinks so much that it will ‘ pull away ‘ from the stone it’s attached to, and in his case, it pulls about 2mm of stone with it.

No I doubt it is epoxy shrinkage causing the problem. High quality epoxy has little or no shrinkage. It would have to be a very poor quality epoxy to be shrinking enough to do that.

The reason his epoxy is not working is that it is too rigid. His existing rigid material has a “high modulus of elasticity”. A material with “high modulus of elasticity” is a material that is stiff and/or rigid. A “low modulus of elasticity” material is semi-flexible, and is not rigid or brittle.

T pieces of the stone structure (in this case a tombstone) and pieces not in touch with the ground tend to get hotter and cooler faster than the larger pieces and pieces with ground contact. This is called “differential timing of the event”. For example the top of a tombstone can be heated and cooled on 5 sides, the top and the 4 sides. The base of the tombstone which is buried in the ground has earth or stone on all of its surfaces. This earth and stone tends to keep the temperature of the base more stable by insulating it and slowing the change in temperature. This works much like the insulation in your house slows temperature changes inside your house.

When an object like a piece of stone is heated it expands (gets bigger). When an object cools it contracts (gets smaller). For example 100 feet of concrete will be 1 inch longer once it is heated 100 degrees F. That is why expansion joints are cut into concrete.

In the case of tombstones all the pieces of the same type of stone have very similar if not identical “coefficient of expansion”. Since the pieces are positioned with potentially different timing of heating and cooling there is a “differential timing of the event” (see above). The result is stress areas you are seeing in the closest weakened plane in the stone near the bond line.

Product #2005 was specifically designed for tombstone (monuments) and/or stone bonding, or repair. Epoxy.com Product #2005 is very strong yet it is has a “low modulus of elasticity” (semi-flexible). The low-modulus of elasticity helps to absorb differential movement (two sections of stone heating and cooling at different times), making it much less likely to cause a stress area in adjacent weakened planes.

Camouflage the bond line rubbing stone dust(ground off the original stone or a similar colored stone) into any exposed epoxy material while the epoxy is still “wet”. That way the dust will stick in the wet epoxy making the epoxy difficult to impossible to see.

Surface Preparation for Resin Systems

January 12, 2016

Surface Preparation Guide
For Concrete, Wood, and Metal Substrates


CONCRETE SUBSTRATES

I. GENERAL INFORMATION

Surface preparation is considered to be the most important step of any resinous flooring application. Improper surface preparation could turn what seems to be a simple process into a lengthy, difficult repair. The following conditions will dictate the type of surface preparation:

A. Concrete Placement
1. Slab-on-grade or on the ground

a. A 10 mil minimum vapor barrier is necessary to prevent moisture vapor transmission. An efficient puncture proof barrier is recommended.

b. Proper jointing will minimize cracking which could transmit through the resinous flooring system.

2. Elevated Slabs

a. Pan construction should be vented.

b. Metal deck construction should be properly jointed to minimize cracking.

B. Curing and Finishing Techniques
1. Curing compounds, if used, must be mechanically removed from the concrete surface prior to all resinous flooring applications.
2. Recommended techniques:

a. Wet cure

b. Light steel trowel finish to minimize laitance and provide hard
surface

C. Age of Concrete

Concrete must be a minimum of 28 days old for resinous flooring applications. Primers are now available which can be used on fresh (green) concrete on some installations. Contact the technical department for details.

D. Previous Contamination can affect the bond of the resinous flooring and must be removed. Types of contamination are:
1. Oil, grease, or food fats can usually be burned off with a flame gun or removed with a commercial degreasing compound or solvent. Epoxy.com Product #201 Oil Stop Primer is an important tool in dealing with petroleum oil contaminated concrete.
2. Curing compounds, sealers, and other laitance are best removed mechanically with:

a. vacuum shot-blasting

b. scarifying

c. sand blasting

E. Present Condition
1. Test for moisture: Coating system bond failures on slabs on grade and elevated/lightweight concrete caused by moisture vapor transmission are the industry’s largest single problem and result in extreme frustration from owners, clients, and contractors. Epoxy.com recommends testing for moisture vapor transmission. The recognized methods are:

a. ASTM-F-1869  Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride: The maximum allowed water/vapor transmission rate is 3 pounds per 1,000 square feet per 24 hours.

b. ASTM F-2170  Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes: This test measures the  relative humidity in the slab below the surface. If taken over a period of time, it will show the rate of drying in the slab. The maximum relative humidity should be below 80%.

c. ASTM-D-4263  Plastic Sheet Test: This test gives an indication that moisture may be present.

2. Moisture related failures can be prevented through:

a. Placing new concrete over an efficient vapor barrier.

b. Testing for moisture vapor transmission as prescribed above prior to resinous flooring application.

c. Applying a moisture vapor transmission reduction system where moisture content is too high for successful resinous flooring applications. See Epoxy.com Product #830 Moisture Vapor Treatment for more details

3. A clean surface is necessary to establish a strong bond between the resinous flooring and concrete.
4. Resinous flooring systems are only as sound as the concrete they areapplied to. All unsound concrete should be repaired or replaced prior to resinous flooring applications. Consult your Epoxy.com Technical Service Department for specific information.
5. Resinous flooring materials should be applied to level concrete substrates. Grind or fill high and low spots prior to application.
6. Repair cracks prior to resinous flooring applications
F. Mechanical Prep vs. Acid Etching

Resinous flooring materials ideally bond to concrete with a rough, sand-paper finish. This finish can be achieved by either acid etching or mechanical methods. The choice of preparation is dictated by the factors above. Other factors which determine the type of preparation include:

1. Ecological restrictions involved with waste removal which could prohibit the use of acid etching and other chemical methods.
2. The type of resinous flooring material: It is recommended that concrete floors be acid etched prior to application of polyester and vinyl ester flooring systems.
G. Acid Etching

The following steps are recommended for acid etching:

1. Dilute commercial muriatic acid with water using 1 part acid by volume to 3 parts clean water by volume. Add the acid slowly taking care to avoid splashing. Workers should be protected with safety glasses, rubber gloves, and boots. If skin or eye contact occurs, rinse affected area thoroughly with clean water and follow Material Safety Data recommendations.
2. Sprinkle acid solution onto the entire surface in order to allow the acid to reach all areas of the concrete. Adequate coverage is
approximately 75 ft²/gallon of acid/water solution. Do not puddle and spread.
3. Scrub the acid solution into the concrete using a stiff bristle broom to remove loose concrete and laitancy.
4. Before rinsing, look for areas where bubbling did not occur. These areas have not been sufficiently cleaned and will require mechanical scarifying and additional acid etching.
5. When the acid solution has stopped bubbling (usually after approximately 15 minutes), rinse the floor thoroughly with water. Do not allow the floor to dry before rinsing because the salts formed by the acid reaction may cause problems with the adhesion and performance of the resinous flooring system. Test pH of the concrete surface to verify that the concrete tests alkaline.
6. Finally, the floor should be dry mopped to remove standing water and dirt remaining after the acid etching. Allow the floor to completely dry prior to the application of any resinous flooring system. Failures can occur in resinous flooring system applications due to moisture remaining
in the substrate.
H. Mechanical Preparation

Contamination and other foreign materials must be mechanically removed to ensure a satisfactory bond. All dust and debris must be thoroughly removed.

II. OLD CONCRETE

Old concrete surfaces must be structurally sound. Any unsound areas mustbe repaired prior to proceeding with the resinous installation. For
proper patching and repairing, use Epoxy.com Technical Service
Department. Remove existing paint, scale and loose concrete by rough
sanding, sandblasting, shot blasting, or grinding. In some cases where
plant conditions allow, a stripper may be used to remove excessive
build-up of paints or sealers.

Structurally sound concrete should be mechanically prepared to remove any contamination. Vacuum shot blasting is the best method for achieving
a good profile for bonding and should be used where possible. Before
installation of any Epoxy.com Product the surface must be examined for moisture vapor transmission using:

ASTM-F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride.

ASTM-F-2170 Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes.

ASTM-D-4263 Standard Test Method for Indicating Moisture in Concrete by the Plastic Sheet Method. This test is only an indication and should not
be used to determine moisture migration.

Other ASTM Tests which are applicable to concrete preparation are:

ASTM-D-4258 Standard Practice for Surface Cleaning Concrete for Coating

ASTM-D-4259 Standard Practice for Abrading Concrete

ASTM-D-4260 Standard Practice for Acid Etching Concrete

ASTM-D-4261 Standard Practice for Surface Cleaning Concrete Unit Masonry for Coating

ASTM-D-4262 Standard Test Method for Ph of Chemically Cleaned or Etched Concrete Surfaces

ASTM-C-811 Standard Practice for Surface Preparation of Concrete for Application of Chemical Resistant Resin Monolithic Surfacing

III. NEW CONCRETE

New concrete must be well cured and dry prior to coating. Allow to cure a minimum of 28 days unless using green concrete primer. No curing
agents or sealing compounds should be used at any time prior to coating. A light steel trowel finish is recommended when finishing the concrete surface.

Any oil, grease, laitance, or other foreign material must be removed. Steam clean with a strong degreaser such as tri-sodium phosphate. Laitance and other foreign material are best removed by mechanical
methods such as vacuum blasting, scarification, or grinding.

All new concrete can be acid etched or mechanically prepared by vacuum shotblasting, sand blasting, scarifying, or grinding. Vacuum shot-blasting provides the cleanest environmentally safe area during
cleaning. It also provides a mechanically rough surface to achieve a
good bond.

When acid etching, use a 3 to 1 dilution of water to acid and follow directions printed above.

Before the installation of any Epoxy.com resinous system, the surface should be examined for moisture. Test for moisture vapor transmission using ASTM F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride. The maximum allowable rate is 3 pounds per 1,000 square feet per 24 hours.

Another procedure that helps determine slab dryness is ASTM-F-2170 Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes. Maximum allowable R.H. for protimeter test is 80%.

WOOD SUBSTRATES

I. GENERAL INFORMATION

Resinous flooring must always be applied directly to exterior grade plywood with extended glue line INTERIOR GRADE PLYWOOD delaminates easily and SHOULD NOT BE USED
as it could result in a failure of the resinous flooring system. MARINE GRADE PLYWOOD contains moisture repellants which could cause a darkening of the resinous flooring system and SHOULD NOT BE USED. All plywood must be completely free of all waxes, varnishes, or other foreign materials.

A. Plywood used to cover existing wood floors
1. Clean and fasten existing wood floor to the floor joists.
2. If the floor is completely sound, fasten ½ Exterior grade plywood “C” plugged with an exterior glue line to the existing floor. Stagger the plywood for strength.
3. ¾” DFPA Exterior or ¾” DFPA Underlayment grade plywood with exterior glue line must be used if the existing floor cannot be cleaned, or is not sound.
4. All plywood must be completely free of all waxes, varnishes, or other foreign materials.
5. Secure plywood with exterior glue.
6. Use Ring Shank or Wood Screws at six (6) inch centers around panel edges and support.
7. Stagger all panel joints, fill joints with epoxy filler, and coverjoints with fiberglass cloth and epoxy resin.
8. Lightly sand the floor surface to insure proper adhesion of the resinous flooring system.
9. Seal all joints and fastener head holes with Epoxy.com Product #2005 – Semi-Flexible Epoxy Gel Adhesive.
10. Prime surface with appropriate primer prior to system application. Surface may require double priming due to porosity of plywood.
B. Plywood used for new construction (plywood is laid directly on the joist)
1.  Exterior grade plywood “C” plugged with an extended glue linemust be used.

All plywood must be completely free of all waxes, varnishes, or other
foreign materials.

2. Use Ring Shank or Wood Screws at six (6) inch centers around panel edges and support.
3. Stagger all panel joints, fill joints with Epoxy.com Epoxy.com Product #2005 For outdoor applications cover joints with fiberglass
cloth and the membrane system being used with the outdoor system.
4. Lightly sand the floor surface to insure proper adhesion of the resinous flooring system.
5. Remove all dust with a vacuum cleaner.
C. Applications with waterproofing:
1. After preparing the floor surface as prescribed above, caulk all joints with Epoxy.com Product #2005 for indoor systems. For outdoor systems use the membrane used with the Epoxy.com outdoor system.
2. Apply the waterproofing membrane as specified.

METAL SUBSTRATES

I. Preliminary Preparation
A. Metal substrates must be structurally sound prior to any resinous system being applied. For best results Sandblast to Commercial Blast (SSPC10 / NACE3) for non-immersion applications and Sandblast to near white metal -(SSPC10 / NACE2) for immersion applications.
B. Remove all foreign materials such as oil and grease with solvents or other degreasing compounds.
C. All scaling and rust must also be removed mechanically by sanding, sandblasting, or abrasion.
II. Treat the blasted/abraded surface with a phosphoric acid solution as
described below in order to prevent rust formation if the surface is
left exposed for some time prior to application of the resin system.
A. Always use a 10% solution of Phosphoric Acid.
B. Mix acid solution in either glass, plastic, or earthen containers (never use metal containers), by adding Phosphoric Acid to water. NEVER VICE-VERSA due to heating or splashing which may occur.
Workers should be protected with safety glasses, rubber gloves, and boots. If skin or eye contact occurs, rinse affected area thoroughly with clean water and follow Material Safety Data recommendations.
C. Apply phosphoric acid solution by either paint brush or rubber squeegee and allow metal surface to AIR DRY.

DO NOT FLUSH METAL SURFACE WITH WATER.

III. Protect surface from contamination until the primer is applied.
IV. Wipe metal surface with MEK solvent immediately before primer
application.

Can I Install Epoxy over Ceramic Tile?

September 21, 2015

I have seen tiles that have been prepared in the lab environment that have epoxy well bonded to it. Doing it in under laboratory conditions and doing it in the field is two different things. In all the over 35 years I have been in the business I cannot point you at a single success story where epoxy was installed over tile.

My company started off as an installation company about 35 years ago.  When we were a young installation company we made build a sizable business by going around behind all of our competitors that were installing epoxy over tile, and redoing their failed work. That is why I typically I recommend against going over ceramic tile with epoxy.

Surface Preparation Requirements

Bonding to tile requires either intense physical abrasion like sandblasting or etching with phosphoric acid to remove the glaze.  If you etch with acid it usually eats up the grout.  Acid may, and more likely than not will, get under the tile and loosen it.

The heat and vibration of the sandblasting tends to loosen tile. Sandblasting will damage the grout. Best case situation the tile will require regrouting.

After all that, a single tile comes loose, or a single piece of old grout comes loose, and you have failed your objective.

Alternatives

Many people like the looks of tile. They don’t like the way tile grout leaks and is hard to maintain. For them I recommend that you remove the grout and regrout it with Epoxy.com Product #225 – www.epoxy.com/225.aspx. Product #225 is a 100% solids water cleanable epoxy that is waterproof grout. This eliminates most leaks and grout maintenance issues.

Thos of you that don’t like the looks of the tile, I recommend removing the tile.  Get down to a sound substrate.  And then proceed. – www.epoxy.com/surfaceprep.htm.

Apply Epoxy.com Product #1W – www.epoxy.com/1W.aspx to the walls. Product #1W is a 100% solids waterproof coating that leaves a ceramic like finish. Product #1W applies much easier than most 100% solids epoxy. It has superior durability and abrasion resistance.

For floors (after the tile is removed) I would level with Epoxy.com Product #12 mortar – www.epoxy.com/12.aspx and then install Epoxy.com Chip Flooring – www.epoxy.com/chips.aspx. Heavy traffic on floors often makes the use of decorative flooring products impossible. Product #315 Seamless Polymeric Multi-Colored Flake Chip Floor Resurfacing System makes this possible. The #315 Chip System creates a beautiful, durable, and affordable floor that is easy to apply by both professionals and do-it-yourself enthusiasts.

Choosing the Right Epoxy Sealer

May 18, 2015

Having the knowledge of which type of sealer to use is extremely important to the overall satisfaction of the job. There are 3 basic types of epoxy sealers. The first is 100% solids epoxy, solvent based sealants and finally water based sealers. There are also urethane and acrylic sealers.

To understand how each sealant works one must understand how they act as an epoxy. http://www.epoxy.com/primersealer.aspx . The 100% solids epoxy when applied to a floor retains a consistent thickness. Epoxy.com #15 http://www.epoxy.com/15.aspx is the best product for maintaining a clear epoxy sealer without any loss of thickness due to evaporation. If you roll a gallon of material on your floor, when it hardens you maintain the thickness of the full gallon of spread coverage.

Epoxy.com #15 can be used to seal previously installed epoxy and river rock stone on pool decks or walkways. It also seals Epoxy Chip flooring, as well as acts as a binger and sealer to Epoxy quartz flooring. It provides protection, just the right amount of shine and helps to keep the water from permeating the underlying concrete. It also works well inside in garages. It is our most versatile sealer that we offer it works great on concrete inside and when properly installed outdoors.

When you apply a water based sealer or solvated sealer you will consistently loose a percentage of the thickness due to evaporation. Even though this is the case there are times when a 100% solids epoxy may not do exactly what you need it to accomplish. In this case we offer products with different components and viscosity to suit your needs as a consumer.

Epoxy.com #671  is a low viscosity, two component, carbon filled, polyamide modified conductive primer/sealer formulated with special wetting agents to provide maximum penetration into concrete surfaces. Product #671 Primer Sealer is ideal for both new and old concrete surfaces. Product #671 Conductive Epoxy Primer Sealer provides excellent resistance to wear, and can be used either alone or as a conductive sealer or as a conductive epoxy primer when used with Product #674 Electro-Static Dissipating Urethane Topcoat and our Conductive Systems.

Epoxy.com #80 is a solvented clear acrylic solution formulated to create a clear, non-yellowing protective coating. Product #80 ACRYLIC SEALER http://www.epoxy.com/acrylic-sealer.aspx provides a tough, UV and abrasion resistant film that effectively protects surfaces from moisture penetration, staining, dirt, dust, and wear. It is good for both indoor as well as outdoor applications. This works well to seal existing terrazzo floors and as well as slate.

For those in California, who don’t want to use a 100% solid material, we offer Epoxy.com http://www.epoxy.com/High-Solids-Urethane-Coating.aspx Epoxy.com # 441 is free of the health and environmental problems normally found in solvent-based urethanes, while maintaining excellent performance properties. The very low VOCs allows this urethane coating to meet the strict low VOC standards. Epoxy.com # 441 Polyurethane Coating and Sealer provides a matte finish. Product #441 water-based urethane coating and sealer has good chemical, stain, and mar resistance.

Finally the most important thing to remember when you are choosing an Epoxy.com Sealer is to make sure you are using The Right Product for The Right Job. If you would like assistance with your selection please call our Technical Support Line at 352-533-2167 and we will be happy to assist you.


Epoxy Cold Temperature

Installing Epoxy in Coolers and Cold Temperature

Extend Epoxy Installation Season into Winter

I have spoken on this subject here before but this time of year I get a lot of calls and emails about installing epoxy in cold temperatures. Our company started out as an installation company in Vermont. Summers are very short and winters are very long in Vermont. To stay a viable company, we had to figure ways of working through the winter.

Tenting and heating areas during the winter is time consuming and expensive. The solution is found in resin products that will set in low temperatures. The most durable and cost effective options of installation at cold temperatures is Epoxy and Methyl Methacrylate.

Cold Temperature Cure Resins can also be used as a super-fast setting Resinous Mortar or Coating at normal temperatures. Our Cold Temperature Cure Resins used at normal temperature give you quick turnaround time for small jobs, or larger jobs that require a short turn-around time.

Cold Temperatures Epoxies

Cold Temperature Cure Epoxy Resins allow installation to be done at low temperatures as low as 35°F., expanding your epoxy coating and epoxy flooring installation season. Epoxy.com Cold Temperature Cure Epoxy Resins can also be used in cold storage areas like food processing areas, where the temperature cannot be raised higher than 35° F or so. Normal cured epoxy typically requires 50°F or more.

Depending on how you mix the aggregate into the products below, they can be used as a mortar for overlays, or a grout for sealing between other hardened construction materials.

Commonly Used Cold Temperature epoxies

Product #1 Cold Temperature Cure Epoxy Coating is 100% solids and specially formulated coatings for cold temperature applications. Cold Temperature Epoxy Coating #1 is able to cure at temperatures as low as 35°F. It is has Zero (0) VOCs. Since it has no VOCs, it has no solvent so it meets the strictest possible standard for a low VOC coating. It is often used in coolers and food preparation areas that require constant low temperatures. Product #1 Cold Temperature Cure Epoxy Coating is also frequently used in room temperature applications to meet super-fast cure, limited shutdown needs.

Product #10 Cold Temperature Curing Epoxy Mortar Resin – This product has a low modulus of elasticity (flexibility) and is Low Viscosity. The low viscosity allows heavy loading of the right fillers. The heavy filler loading helps not only to save money, but helps to maintain better thermal coefficient with respect to concrete and steel. The low modulus of elasticity prevents it from being brittle making it less vulnerable to thermal coefficient differences. It also gives it better impact resistance.
