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

Selecting the Right Floor for a Mechanical Room

July 27, 2015

Mechanical Room Floors are very unique in their use and conditions. You have to consider the installation environment and the function of the floor. Our Mechanical Room Floor will protect the concrete, and contain any liquids that spill.

Systems used in mechanical rooms should be zero VOC. You do not want solvent evaporating from your material. Evaporated solvent could be picked up by your air handling unit sending it through your building. The best way to prevent this is with a VOC free 100% solids resin system. A resin system that is 100% solids has no solvent (or water) in it. It also means when you spread a gallon of material on your floor after it hardens you still have a gallon of material. With water-based and solvent based materials you lose half the material to evaporation.

Mechanical rooms should be chemical resistant. Typically they are top coated with Epoxy.com Product #2 Chemical Resistant Epoxy – www.epoxy.com/2.aspx. If it is a chemical feed room you can supply a list of chemicals and concentrations to the technical support department so you can make sure the #2 is chemical resistant enough.

The systems used for mechanical rooms are impact resistant. The limiting factor is the strength of the concrete substrate. Properly installed the epoxy will stay bonded to the concrete. The only way the epoxy can chip is if you chip the concrete from underneath the epoxy. You can install a thicker epoxy floor for an additional cost if you think you need still additional protection.

The systems recommend for mechanical rooms are highly abrasion resistant and will easily handle traffic up to heavy fork lift traffic. The system can be made even thicker if you have an unusual amount of abusive traffic.

When the mechanical room is over a finished space, it is suggested that a crack isolation membrane be integrated into the system. This can be done with Product #32 Epoxy Membrane System. The advantage of #32 Epoxy Membrane Resin as part of the system is 100% solids and has zero VOCs.

If the mechanical room is shut down and you can handle solvent and want something still more flexible you can use Epoxy.com Product #459 a two component, high solids, elastomeric urethane instead of or in addition to the Product #32 Epoxy Membrane above. Product #459 exhibits excellent elongation properties along with high tensile strength and tear resistance to make it an ideal crack resistant membrane for use under Product #2 and all of our other epoxy mechanical room floor coatings.

One of the primary reasons you need a mechanical room floor over finished space below is to waterproof it. The above methods accomplish the waterproofing in the center of the floor. The edges of the floor can be protective with a coving material up the wall and around pipe penetrations. That can be accomplished with Product #720 Epoxy Coving Resin System which can be used to install an integral cove base for all of our epoxy based mechanical room flooring and most of our other epoxy flooring and coating systems. This provides seamless wall to floor protection.

Selecting the Right Epoxy ESD / Conductive Flooring

June 15, 2015

Conductive and Electrostatic Dissipative (ESD) flooring are used on floors in facilities that need protection for stray static discharges. One example of static discharge is when you walk across a carpet in a very dry room in winter then touch a metal object or another person you get that little electrical zap. Most people find this a bit of nuisance. However if you touch a hard drive or a circuit board and create that same discharge you can damage it beyond repair. Worse yet if you get a static discharge in a chemical or munitions plant where there might be a potentially explosive environment the results can be a catastrophic explosion.

What is ESD Versus Conductive?

Conductive floors have between 100,000 and 1,000,000 ohms of resistance. Electrostatic Dissipative (ESD) floors have between 1 million and 1 billion ohms of resistance. Remember Ohms Law:

Ohms_Law

where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm’s law states that the R in this relation is constant, independent of the current.

Simply speaking the resistance is the ohms of resistance that we are talking about above. The lower the ohms of resistance the stronger the conductive medium to conduct the static charge away. The lower the ohm of resistance the more efficiently the conductive/ESD flooring carries the static charge safely away. .This is one situation where the smaller the number the better.

How does Conductive and Electrostatic Dissipative (ESD) flooring Work?

Think of your Conductive and Electrostatic Dissipative (ESD) flooring as a grounding rod. A grounding rod is that metal rod that gets driven into the earth to increase the surface area coming in contact with the ground. You then attach your building ground or lightening rod to that grounding rod. The Conductive and Electrostatic Dissipative (ESD) flooring is much like that. It makes the whole concrete surface that the Conductive and Electrostatic Dissipative (ESD) flooring comes in contact with a large grounding plane, acting much like a grounding rod. In some facilities this effect is enhanced even more with the installation of grounding strips that the Conductive and Electrostatic Dissipative (ESD) flooring connects to the grounding rod(s). .

Where do you use Conductive and Electrostatic Dissipative (ESD) flooring?

Typically ESD flooring is used in areas to protect electronics. Conductive is more commonly used where there is the potential for an explosive environment. Most facilities that require ESD flooring can use conductive flooring as well. The reverse is typically not true. Facilities that require Conductive Flooring typically cannot use ESD flooring. The good news is that most Epoxy.com ESD flooring can be made to be conductive by first priming with Epoxy.com Product #671 Conductive Primer Sealer – www.epoxy.com/671.aspx.

Epoxy Chip Floors

April 16, 2014

Heavy traffic on floors often make the use of decorative flooring products impossible. To make this possible we created System #315 Seamless Epoxy Multi-Colored Flake Chip Floor Resurfacing System. Our #315 Chip System creates a beautiful, durable, and affordable floor that is easy to apply by both professionals and do-it-yourself enthusiasts.

A Vermont Interstate Rest Area after over 15 years

What is new and unique?

At last there is a high quality seamless floor finish which can be provided in every desirable color combination. This system is easy to use, by any skilled do-it-yourselfer or coating professional. For potential customers, both commercial applicators and the do-it-yourselfer, the final result is most certainly beautiful, affordable, and its durability insures the product to be long lasting, waterproof, easy to clean, and maintenance free.

System #315 Seamless Epoxy Multi-Colored Chip Flooring is available in virtually limitless color combinations. If your job is big enough our chips can be pigmented to match all the colors of many major paint companies. We can color match our base coat colors as well. Unless the pigments for your custom colored 315 Basecoat are unusually expensive we can color match for a modest small batch charge, or at no charge for larger orders.  Even our standard color pallet offers you over 45 chip colors that can be blended in any combination and percentage as you want.

By matching the base coat color in the chip, you make the system much less prone to error.  If you should happen to miss a small spot on the floor the base color shows through, looking like it is just more of that chip in that area.

System #315 chips are also available in 7 sizes ranging from a 1 inch chip down to 1/32 inch chip.  Smaller chips give the look a lot like epoxy quartz flooring. The various colors and sizes allow you to give your floor any number of looks like stone, terrazzo, colored quartz, or vibrant linoleum.

Our clear glaze coat does not yellow quickly like other epoxies.  We have some jobs that have been around for 30 years or more where no yellowing can be found, not even under the urinals in high school bathrooms. This kind of durability is perhaps the most important quality of the #315 Chip Flooring System.  Anyone can provide you with a flooring system that is attractive today.  The #315 Chip Flooring System is the flooring system you need if you want it to stay like that for years to come.
