- Product Highlights
- A high quality, plasticizer free, single component, water-based, 100% acrylic elastomeric coating.
- Designed to provide maximum adhesion and bleed-through resistance over smooth asphalt even in the presence of water.
- Designed to tolerate some standing water when reinforced with fabric.
- May be used over smooth or granulated substrates.
- Adheres to most Aluminized coatings (Adhesion should be verified prior to application)
- Formulated to act as a barrier to block discoloration.
- Has the unique ability to “breath”, providing a completely watertight membrane while allowing trapped moisture to escape.
Applications & Uses
- Applications
- Recommended Uses
Everprime Bleed Block SS Base is designed as a base coat for application over smooth surface asphalt such as built up and modified bitumen substrates. Everprime Bleed Block SS may be used in low areas and waterways when used in combination with reinforcing fabric. With a suitable top coat, it is an exceptional protective system for asphaltic membranes. Check with your Everest representative for top coat recommendations.
- Surface Preparation
General
Surfaces to be coated should be dry, free of dust, dirt, oil, loose granules, peeling coating or other foreign matter.
- Application
This product may be brushed, rolled or sprayed on a clean, dry surface. In waterways or low areas material should be applied as follows:
- Apply Everprime Bleed Block SS Base at a rate of 1 gallon/sq.
- Immediately embed a layer of Evercoat 272 fabric in wet coating.
- Immediately apply a further application of Everprime SS Base at a rate of 1 gallon/sq.
- Allow to cure for at least 24 hours.
For details see Equipment Recommendations at the end of this sheet. It is critical that this be allowed to cure for a MINIMUM of 24 hours and even longer in cool or high humidity environments.
Note: Blistering will occur if top coat is applied over base coat that is not completely dry If any contamination of a thoroughly cured surface occurs, it must be washed with a chemical cleaner before applying subsequent coats. Hand application can be done with squeegee and roller.
Limitations
Surface must be clean and dry. Everprime Bleed Block SS Base is water based and requires evaporation to cure. Material must cure for at least 24 hours. Low temperature and high humidity will slow the cure process. In these situations, even longer cure times will be necessary. Note: Blistering will occur if top coat is applied over base coat that is not completely dry Do not apply Everprime Bleed Block SS Base if there is any moisture on the substrate or risk of precipitation. If applied where there is a risk of vapor drive, such as cold storage and refrigerated tank application there must be a suitable vapor barrier. Everprime SS Bleed Block Base is not intended as a thermal Barrier.

Safety & Health
- Environmental Conditions
Product should not be applied when the ambient temperature is below 32°F or the temperate will fall to within 5 degrees of the dew point within 6 hours after application. Do not apply in late afternoon if high humidity exists, it may cause high moister condensation on the surface overnight.
Ponded Water
- Everest Systems warranties do not cover damage due to ponding water.
- The National Roofing Contractors Association considers ponding water on any roof unacceptable. (See the NRCA Roofing and Waterproofing Manual).
