Elastomeric Coatings & Moisture Barriers in Corrales

Elastomeric coatings serve double duty in Corrales, protecting both roofs and stucco walls from the village's demanding environment. On flat roofs, a high-solids elastomeric coating creates a seamless, reflective, waterproof membrane that extends roof life by 10 to 15 years. On stucco walls, elastomeric coatings bridge hairline cracks caused by thermal cycling and seal the surface against monsoon-driven rain while remaining vapor-permeable enough for adobe walls to breathe. This breathability factor is critical in Corrales: many homes are true adobe or adobe-style construction, and a coating that traps moisture inside the wall will cause more damage than it prevents. Professional-grade elastomerics formulated for New Mexico's altitude include UV stabilizers that resist the chalking and degradation that standard exterior paints suffer within two to three years at this elevation. Corrales' Bosque humidity adds another variable, as the coating must resist mold and algae growth promoted by the higher moisture environment near the river. For horse properties, elastomeric coatings on barn and arena walls resist the abrasion and impact damage that livestock environments produce. The key to performance in Corrales is mil thickness: consumer products applied at 4 to 6 mils fail quickly, while professional application at 20-plus mils delivers the crack-bridging and durability this climate requires.

The most common elastomeric coating project in Corrales is a combined roof and wall application on a flat-roofed adobe home. We coat the roof with white silicone or acrylic elastomeric for reflectivity and waterproofing, then coat the stucco walls with a tinted elastomeric that seals cracks and provides a uniform, refreshed appearance. Second, parapet walls and caps receive dedicated elastomeric treatment because they are the most exposed building element, taking UV from above and rain from all sides. Third, south- and west-facing walls on homes throughout the village receive higher-mil-thickness application to compensate for accelerated UV degradation on these exposures. Fourth, horse barn and arena walls receive impact-resistant elastomeric coating that seals the stucco surface while tolerating the knocks and scrapes of an agricultural environment without cracking or peeling.
