Directions for use: 

Mix 32 to 64 ounces of concentrate with enough water to make one gallon of ready to use solution. 

Preinspect all surfaces for evidence of pre-existing damage and for stains and soiling that will not be possible to remove. Check for and remove any coatings. Coatings will interfere with proper cleaning.

DO NOT USE ON NATURAL STONE

Work process:

1. Post wet floor signs. Protect areas not being cleaned from overspray.
2. Use a pressure sprayer to apply RTU solution to the surface. Use a coarse spray and do not generate aerosol. Allow a 5 to 10 minute dwell time but do not allow solution to dry on the surface.
3. For floors, use a rotary buffer with a nylon grit brush to agitate surface. For counter tops and vertical surfaces, use a hand brush to agitate the surface.
4. Use high pressure water at as high a temperature as possible to pressure wash the surface. Be sure to vacuum up all waste water. Inspect the surface for standing water and remove.
5. If soil removal or degreasing is required, use MasterBlend Grout Devil. Follow the label direction for this product.
6. Establish good drying conditions.
