Acrylic Elastomeric Primers

Priming is often essential to achieve long-term adhesion and prevent coating failure. Applying a dedicated acrylic elastomeric primer prepares porous or weathered substrates like concrete, wood, and masonry, while sealing bituminous surfaces against asphalt bleed-through. While products like ElastEx 200 can function standalone, using an appropriate primer basecoat ensures a uniform surface, bridges micro-cracks, and supports maximum durability under protective topcoats.

Our acrylic elastomeric primers are formulated for multiple commercial and residential substrates. ElastEx 200 adheres to concrete, masonry, metal, wood, asphalt, and built-up roofing surfaces. For bituminous systems and asphalt shingles, BleedEx 400 acts as a targeted prep coat to block oils and asphalt migration before topcoat installation, providing reliable compatibility across diverse flat and low-slope roof assemblies.

An acrylic bleed-blocking primer, such as BleedEx 400, creates a specialized barrier over bituminous surfaces, built-up roofs, and asphalt shingles. It is formulated to stop dark asphalt oils from bleeding through into light-colored or silicone finish coats. At the same time, this water-based prep coat enhances adhesion between the bituminous substrate and subsequent restorative coating layers.

Yes. ElastEx 200 is engineered with a copolymer elastomeric resin that allows it to serve either as a standalone waterproofing membrane or as an elastomeric primer and basecoat beneath reflective topcoats. Its high-solids, low-shrinkage formulation bridges cracks and forms a seamless, weather-resistant barrier that protects against moisture, ultraviolet exposure, and weathering across flat and low-slope roofs.

Coverage rates for ElastEx 200 depend on the container size and application method. A 5-gallon pail typically covers between 450 and 500 square feet per coat, while a 55-gallon drum covers approximately 4,500 to 5,000 square feet per coat. Actual coverage may vary depending on the porosity, texture, and profile of the substrate being coated.

Acrylic elastomeric primers are designed to remain flexible under severe temperature fluctuations. Formulations like ElastEx 200 resist cracking during thermal shock by expanding and contracting with substrate movement. This high flexibility and ultraviolet resistance make them suitable for humid and hot climates as well as coastal environments, preventing moisture intrusion and premature coating failure throughout seasonal weather cycles.
