- Uses
- SC-42 is designed to seal porous concrete, acrylic cement, brick, tile and some previously painted surfaces where a protective finish is desired.
- It is excellent for use as a general concrete sealer.
- SC-42 can be used on driveways, patios and walkways, as it fares well with tire traffic.
- SC-42 can be used in interior and exterior applications and can be used over Westcoat’s SC-10 Acrylic Topcoat to add gloss and over Texture-Crete® Finishes as the final seal coat.
- Inspection
- 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.
- Moisture
- 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.
- Preparation
- 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 the product.
- 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.
- Mixing
Stir prior to use.
- Thinning
- 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.
- Coverage
- Will vary depending on the surface.
- Up to 400 square feet per gallon on a smooth surface and between 200-300 square feet per gallon on a rough surface.
- Applying Product
- Allow the primer or texture to dry completely before applying the product.
- 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 product thinly using adequate pressure to avoid filling in textured surfaces.
- In general, the product will perform better if applied in two thin coats.
- Dry Time
- 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.
- Clean Up
- Uncured material should be removed with an environmentally-safe solvent.
- Cured material should be removed mechanically.
- Limitations
- 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
