Application Information

Area Preparation:

Be sure to mask and cover all areas that are not intended to be stained or sealed including but not limited to door frames, doors, walls and windows.

Surface Preparation:

The surface preparation phase of “Staining a Concrete Floor” should be viewed as the most important. Proper floor preparation results in the product’s longevity, minimizes potential failures and creates the best environment for an aesthetically pleasing work of art. In short, the more detail and time allotted to this phase of the project will dramatically affect the appearance and durability of the finished floor

Application to Bare Concrete:

1) Remove paint, adhesives and loose particulates from the intended application surface.
2) Liberally apply Smith’s Green Clean to a 20 feet x 20 feet section of the substrate with ½ inch nap roller cover.
3) Allow the gel to remain on the substrate for 20 minutes.
4) For exterior application, utilizing a 12,000 work units* pressure washer in conjunction with a 15 degree tip, remove the Smith’s Green Clean with overlapping line patterns. For interior surface preparation, agitate Smith’s Green Clean utilizing a floor buffer (small area) or an auto-scrubber (large area) with Mal-grit brush attachments while rinsing with clean water. Extract material utilizing a wet/dry vacuum or lower the squeegee uptake bar on the auto-scrubber. Continue to flush and agitate the substrate until the rinse water is clear.
5) Allow surface to dry.
6) Perform a "Tape Test".p>

* Work Units = Gallons per minute x PSI

Note: If additional profile is desired, reapply Smith’s Green Clean following the previous directions.

Tape Test: A tape test will help determine the effectiveness of the cleaning process. After the floor has been thoroughly scrubbed, rinsed and allowed to dry; apply several 1 foot strips of high quality 2" clear packaging tape to various locations on the floor. Aggressively press the tape onto the floor with the heel of your hand. Fold one end of the tape into itself and pull it off of the floor as vigorously as possible. Examine the adhesive layer in a bright light looking for residue that was pulled from the floor.
Little to no dust or other foreign particles should be visible. Areas with visible foreign material need to be rinsed again until the surface is free of these contaminants.

Application to Stained Concrete: After allowing a full cure* (minimum 12 hours) time for Smith’s Color Floor, Color Wall or Color Accents, remove all lose particulate utilizing a leaf blower. If standing water is present, remove excess water with cloth or squeegee. Allow substrate to dry before application of Smith’s Seal WB.

* High humidity and lower temperatures will lengthen cure time.

Mixing Instructions: For optimum performance, gentle mixing or agitation is recommended. CAUTION: DO NOT MIX EXCESSIVELY.

Application Method: Smith’s Seal WB may be applied via brush, roller, pump up, HVLP or airless spray.

Spray Application: A typical pump up sprayer provides an easy, economical method of application. Spray as a fine mist, without spurts or dribbles, to form a thin, continuous film. Do not puddle. If puddles occur, brush or roll excess sealer. To increase film build and gloss, we recommend two coats of Smith’s Seal WB. Additional coats may be applied after the previous coat has thoroughly dried.

Roller Application: Use a 1/2 inch (heavy texture) or 3/8 inch non-shed roller cover. Smith’s Seal W/B can be rolled onto stained substrate via a 5 gallon pail or roller pan utilizing the dip and roll method. Material should not be poured onto the stained substrate. Do not over-apply or allow excess puddles.

Brush Application: Utilize traditional bristle brush application for corners, control joints and other hard to reach places.
