Elastomeric Coatings & Moisture Barriers in Bernalillo

Elastomeric coatings are among the most versatile exterior maintenance products for Bernalillo properties, applicable to both flat roofs and stucco walls across the town's diverse building stock. On flat roofs, elastomeric coatings extend membrane life by creating a seamless, UV-reflective, waterproof layer that handles ponding from settlement-induced low spots and protects against the Jemez corridor's intense storm exposure. On stucco walls, elastomeric coatings bridge the thermal and settlement cracks that are endemic to Bernalillo construction and seal the surface against monsoon-driven rain while remaining breathable enough for adobe substrates. The critical distinction in Bernalillo is between coatings for adobe walls and coatings for frame walls. Adobe requires a vapor-permeable elastomeric that allows moisture to escape the wall while blocking liquid water penetration. Frame walls with drainage planes can accept less permeable coatings because the drainage system manages moisture behind the stucco. River corridor humidity makes product selection particularly important: some acrylic elastomerics support mold growth in humid conditions, while silicone-modified acrylics and pure silicone coatings resist biological colonization. Application thickness matters as much as product chemistry. At 20-plus mils, professional elastomeric coatings bridge cracks up to one-sixteenth inch. At the 4- to 6-mil thickness of consumer products, crack-bridging ability is negligible.

The most common elastomeric project in Bernalillo is a combined roof and wall coating on a flat-roofed home where both surfaces are aged but structurally sound. We coat the roof with white silicone elastomeric for maximum reflectivity and ponding resistance, then coat the walls with tinted acrylic elastomeric matched to the homeowner's color choice. Second, targeted elastomeric application on settlement-cracked walls where the cracks are too numerous for individual repair but the stucco bond is still sound. The high-build elastomeric bridges the cracks and provides uniform coverage. Third, parapet wall and cap coating as a stand-alone maintenance service that addresses the most leak-prone exterior element before damage reaches the roof system. Fourth, commercial elastomeric coating on US 550 corridor retail buildings as a scheduled maintenance service that refreshes appearance and extends the building envelope's service life.
