Epoxy-Seal Application Guidelines

General Information/Surface Preparation

• New concrete must be cured for 30 days.

• Use only when air & surface temperatures are 55 – 90 degrees Fahrenheit.

• Surface must be clean, dry, sound and free of dirt, dust oil, wax andgrease.

• Oil stains should be removed with OSR (Oil Stain Remover) or equivalent degreaser.

Method 1 (Preferred)

• Use Seal-Krete Clean-N-Etch to clean and etch the concrete (figure A), triple rinse (figure B). The surface should have the feel of 150 grit sandpaper (figure C). When dry, check the surface with a few drops of water (figure D). Water should penetrate quickly - if not, re-etch affected area(s). Allow to dry completely before applying Epoxy-Seal.

Method 2 (muratic ACID)

• The surface should be cleaned with a good alkaline cleaner, such as, TSP (tri-sodium phosphate) and a thorough rinsing. After etching with muriatic acid, the surface must be neutralized with baking soda and water followed by another thorough rinsing. When dry, check the surface with a few drops of water (figure D) . Water should penetrate quickly - if not, re-etch affected area(s). Allow to dry completely before applying Epoxy-Seal. Note: A one pound box of baking soda added to a five gallon pail of water will cover an area of approximately 500 sq. ft. Note if using muriatic acid to etch it must be neutralized with baking soda: Since muratic acid can only etch the surface then tsp should be used to clean the floor after etching procedure is complete.

• Inter-mix all paint.

• Apply one thin coat of Epoxy-Seal (figure E) with one of the following rollers:
Smooth surfaces (garage floors/basements): 3/16” to ¼” nap roller
Broom finished surfaces: 3/8” nap roller
Rough or textured surfaces: ½” nap roller

• Allow the first coat to dry, 4 -6 hours (this time should be extended for cooler temperatures), prior to applying a second coat in the opposite direction for full hiding.(figure F)

• Allow the coating to cure as follows before subjecting to foot or vehicular traffic:

• Coverage: 300 – 500 sq. ft. per gallon, depending on porosity (Approximately: 2 -3 gallons: 2 car garage/3 – 4 gallons 3 car garage)

• Oil-based paints containing silicone and solvent based sealers or curing agents in addition to, two component epoxy or urethane coatings must be chemically or mechanically removed.

• Latex paints must be sanded, cleaned with an alkaline cleaner (such as, TSP), rinsed and allowed to dry completely.

• Inter-mix all paint.

• One thin coat of Seal-Krete Original Waterproofing Sealer should be used as a bonding primer or, if unavailable, 16-oz of water may be added per gallon for the first coat only (do not mix water with all paint, just the amount you will be using for the first coat alone).

• Apply one coat thin of Epoxy-Seal with one of the following rollers:
Smooth surfaces (garage floors/basements): 3/16” to ¼” nap roller
Broom finished surfaces: 3/8” nap roller
Rough or textured surfaces: ½” nap roller

• Allow the first coat to dry, 4 -6 hours (this time should be extended for cooler temperatures), prior to applying a second coat in the opposite direction for full hiding (wet film thickness for each coat 4 mils )

• Allow the coating to cure as follows before subjecting to foot or vehicular traffic:

• Coverage: 300 – 500 sq. ft. per gallon, depending on porosity (Approximately: 2 -3 gallons: 2 car garage/3 – 4 gallons 3 car garage)

• Do not rinse or clean the surface for at least 30 days after application.

• Tire marking can be removed with a non-abrasive scouring pad and mild detergent (scouring pads used to clean Teflon pans and non-abrasive dishwashing soap is recommended).

• TSP (tri-sodium phosphate) or a good alkaline cleaner can be used to clean the garage floor after the 30 day period. Clean with detergent and shop broom, rinse with a water hose. Using a pressure washer is not recommended as it could damage the coating.

• Do not use caustic cleaners (anything containing abrasive materials or solvents) to clean the Epoxy-Seal.

• Use only when air & surface temperatures are 55 - 90 degrees F.

• Do not apply if rain is forecast 24 hours.

• Do not apply to wood, metal, glazed surfaces or where areas of standing water or hydrostatic pressure are of concern.

• Do not rinse or clean the surface for at least 30 days after application.

• To avoid premature paint failure, do not use abrasive cleaners (such as, orange cleaner, Formula 409, any substance containing solvents) or a pressure washer.

• Heavy foot and vehicular traffic requires touch-up.

• Limit of colorant that can be added to deep base – 8 oz.

• Limit of colorant that can be added to white base – 5 oz.
