Concrete Resurrection RAC Acid Stains
Concrete Resurrection –
Reactive Acid Concentrate
CR-RAC STAIN (ALL COLORS)
**This product may only be used on fully cured concrete. Allow a minimum of 28-45 days of cure time after the concrete is poured to allow ample time for the concrete to completely hydrate.
Amount of square footage stained per gallon varies with the surface texture of the concrete, temperature of the concrete, and ambient conditions. Approximate ranges are as follows.
Non-Diluted - 100 - 200 sq ft per gallon
Diluted 1-1 - 200 - 300 sq ft per gallon
Diluted 2-1 - 300 - 400 sq ft per gallon
Diluted 4-1 - 400 - 500 sq ft per gallon
** Dilute with distilled water only.**
The higher the dilution ratio the lighter the resulting color will be.
Refer to color chart for approximate color.
Always use appropriate safety equipment including but not limited to, goggles, face shield, rubber gloves, chemical resistant clothing or apron, and chemical respirator.
Equipment that comes in contact with RAC Stain must be constructed of plastic or other non-corrosive material. RAC Stain can be applied using a plastic pump sprayer, mop, brush, rag, or sponge. Wash equipment thoroughly after use with water.
Concrete must be clean and free of all dirt and contaminants. Concrete floors must be open and porous prior to applying RAC Stain. Oil and grease must be removed prior to stain application using CR-580 Degreaser. Paint and sealers must be removed prior to stain application using CR-590 Paint & Sealer Remover.
• Interior floors - Required minimum preparation is scrubbing using a floor machine (buffer) with a black pad or sanding screen.
• Exterior surfaces - Required minimum preparation is pressure washing.
Drying / Reaction Time
Allow a minimum of 4 hours drying/reaction time.
After the full stain reaction has occurred neutralize the concrete by scrubbing the surface with an ammonia and water solution (8oz ammonia in 5 gallons water). A stiff bristle brush or broom should be used to scrub in the neutralizing solution. Use a wet vacuum to collect residue and waste water. Dispose in accordance with local, state, and federal regulations.
• Interior floors - Required minimum residue removal method is scrubbing using a floor machine (buffer) with a nylon bristle brush or white pad. Use a wet vacuum to collect residue and waste water. Dispose in accordance with local, state, and federal regulations.
• Exterior surfaces - Required minimum residue removal method is pressure washing. Use a wet vacuum to collect residue and waste water. Dispose in accordance with local, state, and federal regulations.
Caution - Residue runoff can stain and discolor unprotected concrete, buildings and landscape features. It may also cross contaminate previously applied colors.
It is strongly recommended that a clear sealer be applied as a top coat for abrasion and UV resistance.
It is recommended that a non-skid / skid reducer be utilized when sealing exterior surfaces.
• Color Change
The use of CR-607 Olive Mist and CR-608 Azure Sky on concrete which has no vapor barrier underneath (typically exterior concrete slabs) have the risk of partially or completely turning black when excessive amounts of moisture migrate from underneath the slab to the top surface.
• Color Variances
Results may vary from color chart due to differing compositions of concrete. Texture of concrete, age and dilution ratio affect final color appearance. Many slab characteristics show through the stain.
