Roof Spray Sealers and Coatings

Yes, SolarEx roof coatings and sealers are engineered for efficient application using professional airless sprayers, rollers, or brushes. For high-solids acrylic coatings like SolarEx 300, an airless sprayer operating at 3,000 PSI or higher is recommended. Spray application allows commercial contractors to achieve even coverage across expansive surfaces, including corrugated metal roofs, built-up roofing, and weathered asphalt shingle systems.

Silicone coatings, such as SiliconEx 500, are solvent-free, moisture-cured membranes that provide hydrophobic waterproofing and withstand continuous ponding water on flat roofs. Acrylic coatings, including SolarEx 300 and TropEx 310, are water-based, high-reflectivity elastomeric topcoats ideal for sloped roofs and well-drained assemblies. Acrylics offer superior dirt pickup resistance and cost-effective ultraviolet defense, whereas silicones excel in severe weathering and ponding conditions.

Reflective roof coatings, also known as cool roof coatings, contain high levels of reflective pigments such as titanium dioxide. SolarEx 300 reflects over 90% of solar ultraviolet and infrared radiation away from the roof deck. By preventing heat absorption before it enters the building, these coatings lower surface temperatures significantly, reducing thermal strain on air conditioning equipment and helping decrease utility costs.

ShinglEx 800 is a waterborne acrylic sealer and rejuvenator tested by PRI Asphalt Technologies to reduce granule loss by up to 88%. As asphalt shingles age between 5 and 15 years, sun exposure dries protective oils, causing granule shedding. Spraying ShinglEx 800 bonds loose granules, seals microscopic fissures, blocks UV degradation, and restores color without the disruptive cost of roof replacement.

Asphalt-based substrates, including modified bitumen and built-up roofing (BUR), naturally emit bituminous oils that can leach into light-colored silicone coatings. Applying an acrylic bleed-blocking primer like BleedEx 400 seals the bituminous surface, preventing asphalt bleed-through, staining, and discoloration. It also promotes superior mechanical adhesion between the underlying roof substrate and the silicone or elastomeric topcoat membrane.

SolarEx sealers and coatings adhere to a broad range of architectural substrates. Compatible surfaces include metal roofs, weathered asphalt shingles, modified bitumen, built-up roofing (BUR), concrete, masonry, exterior wood, and single-ply membranes such as EPDM and TPO. When restoring multi-surface properties or transitioning between different materials, elastomeric basecoats like ElastEx 200 or SealEx 100 ensure seamless, flexible waterproofing adhesion.
