Fixing Floor Damage with Epoxy

September 6, 2016

Industrial and commercial floors take heavy abuse. The older the flooring the worse shape it is in. Conventional wisdom says that such a breakdown of the floor is inevitable. There are steps you can take to protect your floor before it gets damaged. Once the damage has happened there are steps you can take to permanently repair most damaged floors.

Floor joints, are the source of many industrial flooring problems. The purpose of these joints (in original construction) is to give the concrete a controlled place for the concrete crack as it shrinks. They sometimes are called expansion joints. In theory they will expand when the concrete gets hot.Indoors, where temperature is somewhat stable, most of their function of these joints has ended after 28 days or so of concrete. Concrete does most of it shrinking in the first 28 days.

The downside of these joints in the concrete is that it gives a place for the concrete to start chipping away. See the highlighted (in blue) corners in the illustration to the right. When wheels pass across the top it hammers the edge in the opposite side of traffic flow. This breaks off tiny pieces of concrete (again drawn in blue as a triangle at the edges of the concrete joint). The bigger the area chipped out earlier, the bigger and faster additional chipping happens. Time goes on and “pot holes”start to form in the concrete joint in direct proportion to the number of times wheels have hit a given spot.This can become a major trip and forklift hazard.

The best way to prevent this concrete damage is to fill the joints with Epoxy.com  – Product #11-100% Solids Flexible Epoxy Joint Filler for Saw Cut Joints. The #11 is semi-flexible so it still allows some joint movement but (unlike caulking) is firm enough to support the hard wheel as it passes over the joint, virtually

eliminating the pounding and chipping effect on the sides of the joint. See in this diagram how the #11 supports the wheel as it passes over the joint.

For application on flat surfaces Epoxy Joint Filler for Saw-Cut Control Joints Product #11 can be poured or pumped from an Epoxy.com Binary Pumping Systems. In areas where cosmetics are important mask both sides of the substrate before applying the material.

If the areas are bigger you can use Epoxy.com Product #12  blended with silica sand to make a mortar to fill epoxy_joint_repairthe pothole, then re-cut your joint with a concrete saw as shown in the diagram here. The Product #12 can also be mixed with silica sand and used to repair areas in the center of a slab that might have started as a random crack or because of a chemical spill or due to impact damage.

If you need the epoxy mortar to set at a lower temperature and/or faster Epoxy.com Product #10 Epoxy Mortar Resin in fast or cold cure may be the best option.

Here is an outline of getting your flooring ready and some of the types of flooring we can offer you.

Waterproof Your Life

August 7, 2014

The Concept

About 20 years I had a half way house that came to me and wanted a virtually indestructible waterproof group bathroom. They needed it to be like a shower enclosure for the entire bathroom, and toilet facility. It needed to be easy to thoroughly clean and disinfect.

The resulting system allows you to hose down the entire ceiling, wall and floors. The system that we developed is a completely seamless, waterproof ceiling and coating system. This epoxy ceiling and wall coating is seamlessly integrated with a seamless flooring system. This system is now being used for everything from clean rooms to animal facilities to car washes, daycare centers, assisted living facilities, food processing facilities and more.

The System

Ceiling and Walls

Prime the ceiling and walls with Epoxy.com Product #899 Primer – www.epoxy.com/899.aspx. Product #899 Primer is a 100% solids, low viscosity, moisture tolerant epoxy. It soaks deeply into the substrate, verifies surface preparation, and helps to prevent the much thicker coating from getting bubbles that may be cause by air or moisture trying to escape from the substrate during curing. Allow primer to get hard to the touch.

Before the epoxy primer is 24 hours old (and after the primer is hard to the touch) apply a coat of Epoxy.com Product #1W. The 1W – Wall Coating is 100% solids. It comes in a range of different colors. This means it is zero (0) VOC with no solvent. Just like the 899 Primer the 1W has very little odor. We have even more chemical resistant wall coatings for applications where it is chemicals that are being splashed or sprayed. Contact us if you have strong chemical exposures that you want to contain instead of water.

Let the first coat harden to the touch and before 24 hours add another coat of #1W. Allow the coating to dry over night.

Seamless Epoxy Cove – Optional

Typically the cove is only installed if you are going to install one of the multi-colored flooring systems (Waterproof Floor Options 2 & 3below). Cove is covered in an earlier blog – https://news.epoxy.com/2014/06/25/seamless-epoxy-cove-installation-instructions/. The cove gives you a radius at the bottom of the wall making the floor to wall transition easy to clean and esthetically pleasing.

Seamless Epoxy Flooring System

There are multiple systems that you can use for your seamless flooring portion of the system.

Water Proof Floor Option 1 – Seamless Epoxy Floor coating:

Floor Coating Systemwww.epoxy.com/1.htm. Product #1 applies with the Product #899 primer under it and in 2 coats just like the 1W. The Product #1 is thinner and flattens better on a floor than the Product #1W. You can also add an optional anti-skid to the #1 Floor Coating. The #1 comes in all the variety of colors of #1W.

Waterproof Floor Option 2 – Seamless Epoxy Chip Flooring:

Chip Flooring Systemwww.epoxy.com/chip.aspx is a two component 100% Chemical Resistant Epoxy Chip Flooring. 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. This gives you the architectural choices you need. The top coating for this system is highly UV resistant so since it doesn’t chalk indoors it can last and look great for decades.

Waterproof Floor Option 3: – Seamless Epoxy Quartz Flooring:

Quartz Flooring System with Product #15 – www.epoxy.com/15.aspx – is also an excellent flooring system for those who like the colored sand look with a good midrange chemical resistant system.

Waterproof Floor Option 4 – Seamless Chemical Resistant Flooring:

We can also help you to combine the systems above with our Novolac Epoxy Systems – www.epoxy.com/novolac.aspx for highly chemically resistant versions of those systems. You can also install an Electro-Static Dissipative or Conductive system www.epoxy.com/conductive.aspx.

 

In conclusion the systems above are only a small fraction of the possibilities. With our wide range of colors and chemically resistant systems the possibilities are endless. Please contact Epoxy.com Technical assistance at 352-533-2106 or email me directly at norm@epoxy.com.


Clear Epoxy Over Reclaimed Wood

March 24, 2014

Epoxy Product #15 on Reclaimed Wooden Floor


The floor shown in the photos was installed in a dining
room. Approximate room size was 12’ x 14’.  The lumber was 8″ – 12″ in
width and 3/4″ thick. Tongue and groove edges were routed on the boards. 6
gallons of epoxy were layered on in 7-8 applications. Epoxy was applied with
3/8″ and 1/4″ nap rollers. The final finish was not completely smooth like a
table top due to cupping in some of the boards.

The boards were bonded together because he cut heating
vents in and the cut-outs came out as one solid piece and stayed together
rather than separating back into the individual boards.

The baseboard was also made out of old lumber. The top
edge was rounded and then stained so the machined edge would appear
weathered. 3-4 coats of epoxy
were applied so it is much rougher.

The owner was definitely pleased with the results.

Epoxy Products used to Repair Plant and Shop Floors

November 7, 2012

Industrial Floor Maintenance with Epoxy

Preventing and Fixing Deteriorating Floor Joints and Potholes

It is said that there are two types of concrete floors, those with cracks and those that are going to crack. Cracks and potholes in plant and shop floors are a major problem to safety and aesthetics. Here we will discuss what causes them. We will also discuss how to repair them quickly and economically. For those floors that have not cracked we will discuss how to minimize or prevent the cracking and potholes.

It is a common misconception that heavy loads on the floors cause most flooring problems, and so it cannot be prevented. If you are building a new plant or shop floor there are steps that will help to prevent most flooring problems. For existing flooring problems we will discuss how to fix the problems and prevent the problems from getting worse.

Causes of Cracking and Potholes in Shop Floors

Most concrete flooring problems are caused by one of the following:

  1. Improper installation of the concrete, or poor concrete
  2. Improperly cut expansion joints
  3. Steel and hard rubber tires eroding unfilled expansion joints, random cracks and potholes
  4. Chemical attack

Proper installation of Concrete in New Plant and Shop Floors

For new construction make sure you specify and get high quality high strength concrete. Create a box-out form around beams, pipes and other penetrations that go through your floor. Be sure that the corner of your box-outs line up with the saw-cut joints that you will be putting in the floor. Penetrations through the concrete cause a “weakened plain”. A weakened plane is typically created at the shortest distance between the box-outs. That is typically from the corner of one boxed out area to the next closest boxed out area.

Do not allow your concrete finisher to over finish your concrete. Concrete finishers tend to over-finish concrete because they are concerned that if they don’t the owner will not like it. Over-finished concrete does look better than properly finished concrete until the over finished starts to deteriorate. The deterioration cause by over finished concrete typically does not take very long to occur.

The best finishing of concrete leaves it flat, but does not bring up the “cream” in the concrete. It will not look as shinny and smooth but concrete that is not over finished will look more attractive and be more functional over time. Bringing up the “cream” in the concrete is done by over working the mix or adding too much water or adding water to the batch. The “cream” consists of dust from the aggregate and Portland cement.

This “cream” creates a great looking finish at first, because it is so weak, it chips easily. This “cream” has too high a water content so you tend to get micro-cracking in the surface. When your concrete finisher is power troweling your concrete and starts splashing water into the surface as he is finishing it he is about to over trowel the concrete and bring up the cream. It is time to get the concrete finisher to stop troweling.

Water curing of the concrete is what most state highway departments require to cure concrete bridge decks. Wet curing is favored over other methods by the US Army Corps of Engineers. Wet curing will help to stop the top of your concrete from drying out too fast. If you cure with a curing compound instead of water, you will need to remove the curing compound to install high quality coatings and sealers.

Proper curing will help to prevent “curling” of the concrete slab, and help to prevent micro-cracking (crazing) of the surface. Curling is caused when the top dries and shrinks before the concrete underneath dries and shrink. This works much like a bimetallic strip used in a thermostat, the concrete will twist upwards or curl. Proper curing helps to prevent concrete curling and the cracking that will result from it. Another major advantage of wet cured concrete that is not over finished is that there is much less surface preparation required when you go to coat or seal it.

Cut expansion joints often enough, wide enough, and deep enough. Typically the best way to cut concrete down to 16 foot by 16 foot squares or even smaller. The larger the spacing between saw cut joints the more likely you are to get a random crack where you do not want it. The concrete should be cut-up as square as possible. Care should be taken that all the saw cut joints line up with each other in a checkerboard pattern. Be sure the cut is at least 1/3 of the way through the slab, and that the cracks are 1/4 inch or wider. That way all the plastic shrinkage (drying) cracking should occur under the saw-cut relief joint.

Using Epoxy to Protect New Plant Shop Floors

Seal or coat the concrete to protect it against wear and chemicals. Epoxy.com Product #223 Water Based Curing Compound, Sealer and Bonding Agent is a two component water based epoxy curing that is used to both cure and seal concrete. Epoxy.com Product #223 www.epoxy.com/223.htm is an excellent choice for installers that want a long pot life product that is easy to use. Epoxy.com Product #223 is an excellent choice as a sealer where waiting 28 days to seal the concrete is not an option. Product #223 can be installed as early as early as 7 days after the concrete is poured. Giving you early protection.

Allow the concrete to dry for 28 days so that most of the shrinkage at the expansion joint has taken place. Clean the crack thoroughly, then install a bond breaker “rope” in the bottom of the joint. Then fill the joints with Epoxy.com Product #11 Saw-Cut Control Joint Fillerwww.epoxy.com/11.htm. Epoxy.com Product #11 Saw-Cut Control Joint Filler is a 100% solids zero (0) VOC, flexible epoxy joint filler for saw-cut joints of concrete slabs on grade, or to repair existing slabs.Random cracks and improperly filled expansion joints are where the potholes in plant/shop floors are born. As steel and hard rubber wheels pass over these unfilled cracks and joints it hammers the edge of the crack in the direction of the travel. This action cause small chips. As the process continues small chips become larger chips. Soon you have a small pot hole and the damage continues to accelerate.

Epoxy.com Product #11 Saw-Cut Control Joint Filler absorbs the impact and shock of heavy loads and steel wheeled traffic, preventing erosion of control joint edges. Epoxy.com Product #11 prevents the “jack-hammer” effect on the joint that you are traveling towards. This will help prevent most if not all of the “pot-hole” effect that most plant floors see developing at their expansion joint over time.

If you want to seal your floor using a 100% solids epoxy use Epoxy.com Product #899 – www.epoxy.com/899.aspx for sealing the concrete. Epoxy.com also has a wide variety of shop floor coatings and trowel down systems. Contact Epoxy.com Technical Support Department with your specific needs for a recommendation.

Repairing Random Cracks in Floors with Methyl Methacrylate

Random cracking in plant / shop floors can easily and economically be repaired with Epoxy.com Product #685 Liquid MMA Polymer Crack Repair Resin a penetrating gravity feed crack healer for concrete. It is a two component Methyl Methacrylate resin system that polymerizes in place. The extremely low viscosity will penetrate into concrete cracks as fine as 0.003 inches. Epoxy.com Product #685 welds the crack back together making the concrete as strong as it was before it cracked.Repairing a Shop / Plant Floor with Epoxy After it is Damaged.

For those who have already built their buildings you can still fill all the joints especially in the traffic areas with Epoxy.com Product #11 – www.epoxy.com/11.htm. Filling the joints with Epoxy.com Product #11 will prevent additional potholes from forming in areas where there are none yet. To fill the “potholes” in level areas you will typically want Epoxy.com Product #25 – www.epoxy.com/25.htm. Epoxy.com Product #25 is a 100% solids epoxy resin and specially selected aggregate system. Units are preproportioned for ease of mixing and use on the jobsite. Epoxy.com Product #25 is a flowable, self-leveling grout, with handling and physical characteristics superior to similar grouts. Epoxy.com Product #25 is conveniently packaged and makes “pothole” repair in your shop/plant floor quick, easy, and economical. The Epoxy.com Product 25 is the best material when you are looking for a convenient packaging and is easy to use for small jobs.

For larger projects or surfaces that have a slope so you cannot use a self leveling material should use Epoxy.com Product #10 – www.epoxy.com/10.aspx and Epoxy.com Product #82 Mortar Blend Aggregate. With the right mixing equipment you can put up to 100 pounds of #82 into 1 mixed gallon of Epoxy.com Product #11. That gives you a nice stiff mix, and excellent economy. Epoxy.com Product #10 is a low-mod material, with high strength. That makes it perfectly suited for outdoor patching. Epoxy.com Product #10 is the best material for most large jobs.

If you cannot allow overnight for your epoxy patching material to cure you will want to use Epoxy.com Product #680 Polymer Concrete. Product #680 is a methyl methacrylate reactive resin concrete used for repair of concrete structures with a minimum of downtime. Epoxy.com Product #680 develops strength rapidly. Epoxy.com Product #680 Polymer Concrete can be put in service in as little as one hour even at temperatures below freezing. The Epoxy.com Product #680 polymer concrete produces extremely high strengths and is chemical resistant. Epoxy.com Product #680 is prepackaged for easy mixing and placing at the job site. Epoxy.com Product #680 Polymer concrete cures hard in about 1 hour, allowing for quick turnaround of the area being patched. Epoxy.com Product #680 is the best material when you need the patch to set in about an hour.

If the concrete has a lot of pitting in it, you can apply a “scratch-coat”. A “scratch-coat” is done as follows:

1. Carefully measure epoxy resin and hardener. Mix for 3 minutes.

2. Add aggregate to the mixed resin and hardener above, and mix completely.

3. Pour out the epoxy resin hardener and aggregate blend onto the concrete.

4. Then pull a very tight troweled coat over the entire surface, filling the low spots while scraping as much epoxy resin and aggregate material as possible away from the high spots.

The material for a “scratch-coat” is with Epoxy.com Product #10 – www.epoxy.com/10.htm and Epoxy.com Product #78 Self-Leveling filler. Epoxy.com Product #10 and Product #82 mortar blend aggregate is the best blend for building ramps and smoothing uneven transitions between slabs.

Just because your floor is already damaged by chemicals, doesn’t mean it is too late. Most floors can be saved with proper patching (as
discussed above) and a chemical resistant flooring system installed over the patching system. Contact Epoxy.com Technical Support for assistance.
