What to Do Before You Apply Epoxy-Coat

Before you begin the process of applying epoxy coating, inspect your concrete floor. 

We recommend patching all cracks after preparing the floor but before coating application. Since mortar joints/saw cuts are engineered for movement, Epoxy-Coat does not recommend patching them before coating. Epoxy-Coat patch kits and caulk can be purchased online.

To determine whether the concrete has been previously sealed, you can perform a simple test by pouring a small amount of water onto the surface in various areas. If the water beads, a sealer is present and needs to be either chemically or mechanically removed with a diamond grinder.

Epoxy-Coat recommends using the moisture test kit called “Vapor Gauge,” sold at www.epoxy-coat.com, before application. If your test finds the moisture level of the concrete is high, call Epoxy-Coat technical support at 800-841-5580 for instructions. 

What is the Ideal Temperature for Applying Epoxy-Coat? 

The ideal temperature range when working with Epoxy-Coat is 40F-85F (4C-30C) with humidity of under 85%. Applying Epoxy-Coat in the evening works well.

Prepping the Floor for Epoxy-Coat Application

First, sweep or power blow off the entire floor surface area. Typically, old concrete floors have contaminants that must be removed before coating. Using a diluted degreaser and hot water, scrub those areas vigorously. It’s essential for all contaminants to be removed prior to coating. 

Next, combine the pre-mix acid granules and five quarts of water into a pump sprayer. Apply the mixture to the floor by sections and scrub it into the floor with a hard-bristled broom. After that is completed, apply baking soda to the floor and double-rinse with water. 

You need to allow the floor to dry completely before applying the coating. 

Mixing Instructions

Step 1:

Unpack your epoxy kit and assemble the mixer to a high-speed electric drill

Step 2:

Mix Part A Resin for two minutes

Step 3: 

Pour all of Part B into a large mixing bucket

Step 4:

Pour all of Part A into the same bucket

Step 5: 

Mix all contents for 3 minutes using an up-and-down motion

Note: The mixture has to be applied within 45 minutes.

Application Instructions

Step 6: 

Pour mixture along a wall and use a brush to apply at the edges

Step 7: 

Pour a second strip of mixture parallel to the first

Step 8:

Roll the epoxy with a squeegee from the back wall until there are no more parallel lines

Step 9:

Use a roller to roll out the epoxy finish consistently 

Step 10: 

If using decorative flakes, apply evenly throughout the coating 

Step 11 (optional): 

Apply a non-skid polyurethane clear coat 

Top Coat Recommendation 

A top coat is not required, but we highly recommend that you do apply one to extend the durability and beauty of your epoxy floor. 

Drying Time 

You should allow for 24 hours of drying time and keep water off the surface for 7 days. 

Applying a Primer or Multiple Coats 

When applying a primer or multiple coats, wait 10-15 hours between each application.
