Strong Adhesion
Extremely adhesive primer for reliable coating system performance.
Product Overview
CRS Bleed Block Primer is a single-component, low VOC water-based acrylic primer engineered for strong adhesion and bleed blocking performance.
It is designed to resist asphalt oils from migrating through the coating system and staining or discoloring the topcoat.
Its low viscosity and substrate penetrating characteristics help it perform well on a range of roofing surfaces and prepare them for a high quality silicone topcoat.
Suitable Surfaces
CRS Bleed Block Primer can be used on:
MOST FLAT ROOFS*
*Except single-ply membranes.
CONCRETE
METAL

APPLICATION & USAGE
Bare uncoated asphalt roofs
1.5 gal per 100 sq. ft.
Allow up to 48 hours before applying topcoat.
Most Flat Roofs
1.5 gal per 100 sq. ft.
Apply in 1 – 2 coats.
Raw Asphalt Roofs
Approx. 1 – 1.5 gal. per 100 sq. ft.
Usage may vary depending on how old or dry the surface is.
- Apply 1–2 coats, depending on surface type, age and condition.
- Apply to a clean, dry surface using a 1/4-inch exterior paint roller nap/cover.
- Reinforcing perimeter drip edge, seams, penetrations, and other suspect areas before applying the topcoat is highly recommended.
