Waterborne Epoxy Garage Floor Training Video | Slide-Lok Garage Interiors

Garage floor install & training video for our new waterborne epoxy products. Epoxy 150 and 250 are waterborne epoxy coatings based on raw materials that have been used extensively in industry for over 40 years

Epoxy 150 is an epoxy primer / vapor barrier capable of resisting up to 12 pounds of moisture vapor transmission (MVT) pressure in concrete. This is a two component water based epoxy primer with excellent adhesion to damp concrete slabs, and can even be used to remedy concrete flooring with high moisture levels before application of other coating products. This product can also be applied to green concrete, where it acts as a concrete curing compound.

Epoxy 250 is a two component waterborne epoxy primer and build coat system that features easy application, low odor, and excellent coating performance. The amine hardener used in this system cures blush free over a wide range of temperatures and has excellent adhesion to damp concrete. This epoxy can be used as a general purpose primer or build coat for chips underneath an epoxy or urethane top coat. Epoxy 250 is recommended for coating warehouses, commercial flooring, automotive repair, garage floors, and other commercial and industrial flooring applications.

This training video is not meant to be your sole source of floor training. This video assumes prior flooring knowledge and industry best practices when it comes to preparation, application, handling of materials and hygiene.

When possible, we always prefer mechanical preparation methods for concrete. Such methods include diamond grinding and shot blasting. Acid etching and pressure washing is only recommended on light duty flooring with minimal chemical stains.

Begin by prepping your flooring surface. In this video we show installation at the location of a new home build, where the concrete pad is less than 6 months old with very minimal oil stains. In this situation the homeowner was okay with the less than standard flooring preparation and was made aware of the risks of acid etching vs grinding. A light cleaning and de-greasing removed the oil stains. A 1 part acid, 4 part water solution was prepared using muriatic (HCL) acid and water. Remember the old trick from your school days, always add acid to water, like A&W root beer. Brush this solution over the entire floor. Let the acid solution etch the floor for 10 minutes. Prepare a 1 part ammonia, 7 part water solution to neutralize the acid in the concrete. Brush the neutralizing solution over the entire floor. Then rinse and squeegee the floor. Use pH strips to test the floor to make sure it is back to neutral before moving on. Blow dry the floor to remove excess pooling water.

Do not proceed to coating the floor if the floor is too wet or pooling water. Our waterborne epoxy 150 and 250 can be applied over damp, but not wet/pooling water. A good way to test this is by placing your finger on the damp/wet concrete for a few seconds. When you lift your finger it should be dry, if your finger is wet and has a clear film of water on it then the floor is far too wet to coat. Remove standing/pooling water before coating concrete.

Prime coat: Use our Epoxy 150 to prime the concrete. This material is perfect for damp concrete and features excellent adhesion. Mix according the label (2A:1B adding 1 part water). Cut in the flooring joints and verticals before rolling the floor. Wait 45-60 minutes or until almost tack free to apply the next waterborne coating (epoxy 250). In this instance we went to get lunch while we waited.

Chip or Mid coat: Use our Epoxy 250 as a build coat to chip into. Mix according to the label (2A:1B adding 1.5 parts water), a drill mixer is necessary to ensure proper pigment dispersion. Cut in the floor ensuring you thoroughly coat all verticals and cross joints before proceeding to coat the rest of the floor. Broadcast chips as desired. This coat will take 6 hours to be tack free, with plenty of open time to broadcast your chips. This coating is water based, so a solvent free / solvent reducible top coat needs to be applied a day later.

Come back the next day.

Scrape the chips in at least 4 directions. This ensure that all loose chips are removed and you have a smooth surface to top coat.

Top coat: Prepare our 85% solids polyaspartic for the top coat. You can cut polyaspartic with up to 10 oz./gallon using urethane grade solvents as desired (Acetone, MEK, Xylene, PCBTF). Cut in flooring joints and verticals and coat the floor.
