Elastomeric Coatings: Waterproofing Masonry and Stucco

Goal: Evergreen blog synchronized with Newsletter 4, capturing commercial/masonry searches.

If your home or commercial building features masonry surfaces—such as a concrete foundation, a brick chimney, or complete stucco siding—standard paint is not enough to keep water out. Masonry materials are naturally porous, acting like hard sponges that pull moisture in from the air.

During heavy summer rainstorms along the coast, wind drives water deep into these porous walls. Over time, this moisture migrates inward, causing interior water damage, peeling plaster, and structural cracking. To stop this specific issue, property owners rely on heavy-duty Elastomeric Coatings.

Unlike standard residential paints, an elastomeric coating is formulated to be up to ten times thicker. When applied, it forms a heavy, rubberized waterproof layer over rough masonry.

The unique engineering properties of elastomeric systems:

• Bridges Hairline Cracks: The thick liquid completely fills and seals fine cracks in stucco and concrete blocks, blocking leaks before they can grow.
• Exceptional Elasticity: These coatings can stretch up to 300% without breaking, allowing them to bridge shifting masonry cracks as temperatures change.
• Superior Weatherproofing: Acts as a complete barrier against wind-driven coastal rain, keeping your building interior dry and safe.

Using the right technical coating for your specific building material ensures long-term structural health.
