Hard Troweled Floor Pre-Treatment

Hard Troweled Floor Pre-Treatment Solution is used to chemically-profile  exceptionally smooth machine-troweled concrete floors and ultra-smooth pre-cast countertops. Surfaces that do not readily absorb water or have dark spots caused by excessive troweling require either etching with Hard Trowel Floor Prep or sanding with an 80-grit pad prior to acid staining or sealing. The surface should have a light sandpaper texture before proceeding.

Dirty floors with paint overspray or light dry wall mud contamination can be cleaned using Hard Trowel Floor Prep in addition to etching the concrete for acid stain or concrete sealer application.

MIXING INSTRUCTIONS AND COVERAGE RATES

For a full strength concentration, mix each packet with the appropriate amount of water (1-quart bag per quart of water, etc.) in a 5-gallon plastic bucket until the material is completely dissolved.

The product should only be used full strength for heavily soiled or burnished concrete floors. Always conduct a test area prior to the actual project application.

For most very smooth, machine troweled floors, add one part full strength Hard Trowel Floor Prep to two parts water (2:1). Mix thoroughly.

Use a more concentrated 1:1 solution for intense etching action on excessively smooth floors with black spots and/or obvious surface fractures. Each gallon, diluted or full strength, will cover approximately 200 sq. ft. per gallon.

Hard Troweled Floor Pre-Treatment can cause a slight darkening of the concrete after application. This in no way inhibits acid stain reactivity or sealer adhesion. Apply 2:1 for cleaning floors and as a pre-treatment for staining concrete countertops and sealer application.

HARD TROWELED PREP APPLICATION

Clean the concrete surface with Direct Colors Concrete Cleaner and Degreaser

Rinse thoroughly

Using a foam brush, apply small test areas with different concentrations to determine which dilution produces the best staining results.

The product should be sprayed from a pump-up sprayer or spray bottle for countertops in a consistent manner over the entire surface for uniform etching/cleaning.

The Hard Troweled Floor Pre-Treatment should not be poured directly onto the floor or countertop and swept over the surface.

Allow the product to remain active for 20 minutes and neutralize with clean water.

Use a wet/dry vacuum or sweep off the surface to remove and allow to dry.
