Liquid Applied Elastomeric Waterproofing Membranes

These elastomeric membranes are formulated to adhere to diverse building materials. Depending on the product, compatible substrates include metal, concrete, masonry, wood, asphalt, built-up roofing (BUR), modified bitumen, and single-ply membranes such as TPO and EPDM. Certain formulations also apply to spray polyurethane foam (SPF) and mineral-surfaced cap sheets.

Cure rates vary based on ambient temperature, humidity, and the specific formulation. For instance, SealEx 100 achieves skin-over within 4 to 6 hours and cures fully within 24 hours under standard conditions. Moisture-curing silicone systems such as SiliconEx 500 cure through ambient air moisture, forming a watertight barrier soon after initial application.

Yes, specific formulations provide dedicated resistance to ponding water on low-slope and flat surfaces. SiliconEx 500 features a 100% silicone, moisture-cure chemistry that provides permanent ponding water resistance. Water-based membranes like SealEx 100 are also engineered to prevent leaks and water intrusion across low-slope roofing surfaces.

Liquid elastomeric waterproofing membranes can be applied using a brush, medium-to-heavy-nap roller, or industrial airless spray equipment. For spray application of acrylic products like SolarEx 300, contractors utilize commercial airless spray rigs capable of operating at 3,000 PSI or higher to ensure uniform coverage across large roof surfaces.

SolarEx products are packaged to support both small repairs and large commercial installations. Container sizes include standard 5-gallon pails, 55-gallon drums, and bulk pallets containing 36 pails (180 gallons). SiliconEx 500 is also offered in 1-gallon and 4-gallon units, accommodating projects of varying scale.

Yes, elastomeric basecoats like ElastEx 200 and SealEx 100 can be top-coated with reflective coatings such as SolarEx 300 or FirEx 700. This multi-layer system pairs crack-bridging elastomeric waterproofing with high-reflectivity finishes that deflect solar radiation and reduce surface heat absorption.
