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.
