• SC-10 is specially designed to be used as a topcoat for the MACoat™, ALX™ and Texture-Crete® Systems, as well as a stand alone coating over concrete when properly prepared.
• The SC-10 Solar Reflective Series is also designed to be used in the Solar Reflective Finish Systems.
• SC-10 is an excellent product to recoat many other waterproof acrylic deck coating systems.

• Substrate must be clean, dry, and free of grease, paint, oil, dust, curing agents, or any foreign material that will prevent proper adhesion.
• Over previously coated systems, surface must be structurally sound with no peeling or flaking.
• Over sheet metal, metal should be bonderized, clean and free of rust.
• If galvanized metal is used, it must be free of oil and abraded.

• All concrete should be tested for moisture before applying a seamless coating.
• If moisture emissions exceed 5 lbs/1000 square feet/24 hours (ASTM F1869) or if the relative humidity (RH) exceeds 75% (ASTM F2170), contact the manufacturer before application.

• For concrete, the surface should be at least 2500 psi and have cured for a minimum of 28 days.
• Prepare concrete to a profile equal to CSP 2-3.
• You may mechanically profile by grinding or shot blasting.
• The concrete should be porous and be able to absorb water.
• Prior to starting work, test existing concrete slab for efflorescence, moisture and hydrostatic pressure.
• Vacuum surface entirely and ensure that any dust or contaminates are removed, as these will deter adhesion.
• As a topcoat for ALX™, MACoat™ or Texture-Crete®, apply directly over the textured surface.
• If texture has been left for more than 72 hours or it has become dirty, clean as needed prior to application of SC-10.
• Over previously coated acrylic deck coatings, prepare surface by scrubbing with a nylogrit brush on a floor buffer and follow by powerwashing.
• A compatibility test should be done.
• Over sheet metal, the metal should be clean, etched and wire brushed, if needed, to allow product to bond.
• Remove any mildew or algae using 50/50 water and household bleach.
• Rinse thoroughly.

• Over concrete surfaces or previously coated acrylic deck coatings, prime using EC-11 Water-Based Epoxy for best adhesion.
• SC-10 may also be used as a primer if reduced 50% with water.

• Use a mechanical mixer at a slow speed, until a homogeneous mixture and color is obtained.
• For color consistency, box all material to be used on the same project.
• Use care not to allow the entrapment of air into the mixture.

• The material may be thinned by adding up to a maximum of one quart of water per gallon, for the first coat.
• For best results, it is not recommended to thin the final coat.

• Will vary depending on the surface.
• Up to 400 square feet per gallon on a smooth surface and between 125-300 square feet per gallon on a rough surface.

• Allow the primer or texture to dry completely before applying the SC-10.
• This product can be sprayed, brushed or rolled.
• If rolled, neatly cut-in all edges with a brush and roll the center using a 3/8 inch to 3/4 inch nap, good quality roller cover.
• Be sure to spread evenly in a “V” pattern rolling in both directions.
• Apply the SC-10 thinly using adequate pressure to avoid filling in textured surfaces.
• In general, the product will perform better if applied in two thin coats.

• For best results, allow the product 4-6 hours drying time at 70 degrees before permitting light pedestrian traffic or additional coats are applied.
• Allow 24 hours to cure before heavy traffic is permitted.
• Allow 48 hours before heavy objects are placed on the surface and allow 72 hours for vehicular traffic.
• Allow 5 days prior to any abrasion or chemical exposure.

• Uncured material should be removed with an environmentally-safe solvent.
• Cured material should be removed mechanically.

• This product is designed for professional use only.
• Apply in thin coats.
• Concrete must be free of sealers, wax, or curing agents.
• Be sure to paper off any areas that you do not want stained.
• Will not hide imperfections or stains in concrete.
• Fast stain will stain concrete and can produce a mottled look. Colors and effects will vary.
• Do not allow any westcoat products to freeze.
• Read product specification sheets for every product you will be using before beginning the project.
• Stains are translucent and somewhat transparent.
• For interior use only.
• Caution: when mixed with acetone, product is extremely flammable

Product continues to cross-link and harden for 30 days.
