SMARTCOAT 200 Asphalt Bleed Blocker is a water-based formulation manufactured with premium acrylic resins that are designed to block bituminous oil exudate or “bleed-through” from staining SMARTCOAT 400 series coatings. Though SMARTCOAT 400 series coatings do not require primer for adhesion to most bituminous surfaces such as built-up roofing (BUR) or modified asphalt, SMARTCOAT 200 also enhances adhesion to these substrates

1. Clean roof surface thoroughly with SMARTCOAT 100 Roof Wash. Surface must be free of contamination that may inhibit adhesion. Surface must be clean and dry, free of moisture both on and beneath the surface before applying primer.

2. Lightly hand mix before using. Do not dilute. Apply only at temperatures between 50ºF and 110ºF and no threat of rain for 48-72 hours. Apply on warm, sunny days, preferably in the morning hours to provide maximum cure time.

3. Using roller, brush or spray equipment, apply to the properly prepared surface at stated coverage rate.

4. Allow to completely dry, typically 4-6 hours before the application of SMARTCOAT 400 Series Coating. SMARCOAT 200 is light grey and glossy when applied; product will be darker with a matte surface when dry. Once dry, SMARTCOAT 400 Series Coating shall be applied as quickly as possible to avoid compromised adhesion.

5. Clean wet coating with soap and water. Dry coating may be removed with mineral spirits. Use care when handling solvents.
