Inspection
Substrate must be clean, dry, and free of grease, paint, oil, dust, sealers, wax, curing agents, or any foreign material that will prevent proper adhesion. Not intended for exterior applications.

Moisture 
All concrete should be tested for moisture before applying a seamless coating. If moisture emissions exceed 5 lbs/1000 square feet (ASTM F1869) or if the relative humidity (RH) exceeds 75% (ASTM F2170), contact the manufacturer before application. 

Preparation 
For concrete, the surface should be at least 2500 psi and have cured for a minimum of 28 days. Prior to starting work, test existing concrete slab for efflorescence, moisture and hydrostatic pressure. Methods of preparation may vary according to the desired outcome. Factors include the forecasted use of the surface, the environment in which it is to be installed and if a sealer will be used. When preparing the surface, take in to consideration the desired final look and prep accordingly. For more information on preparation, please refer to the appropriate System Specification Sheet.

Mixing
For ease of mixing, begin by adding a small amount of acetone into the SC-36 Fast Stain powder container. Pour approximately 6 ounces of acetone into the half pint container of pre-measured Fast Stain powder (1 gallon mix) or 12 ounces of acetone into the pint container of pre-measured Fast Stain powder (5 gallon mix). Replace the lid and shake to dissolve the powder. Once powder has dissolved, place a funnel in the opening of the 1 or 5 gallon acetone and pour contents of first mix into remaining acetone. Shake entire mixture and let sit for 15 minutes, shake again and the Fast Stain is now ready to apply. Colors may be varied by adding more or less acetone.

Thinning
Do not thin.

Applying Product
Before beginning any project, it is recommended that a mock-up be installed to help indicate the overall look and finish. Material may be applied with a solvent safe sprayer. For best results, use a solvent safe, pump sprayer with a conical tip. Be sure to apply evenly and consistently with an overlapping circular or figure eight pattern. Avoid puddling the stain. Additional coats may be applied after the first coat has dried for 10 to 20 minutes. Additional coats will produce a darker color. Multiple colors may be layered or sprayed at the same time to create a variegated finish. Be sure to paper/plastic off any areas that you do not want dyed. 

SC-36 may leave residual dye on the surface after application. If this occurs, it is recommended to remove excessive dye. A white pad may be used “dry” on a floor machine to remove residue, then a dust mop or vacuum can be utilized to collect the residual dye. 

Be sure to extinguish all pilot lights and sources of ignition. Ventilate the area prior to starting the job. Acetone fumes are extremely flammable.

Clean Up
Cured material should be removed mechanically or with an environmentally-safe solvent.
