Dap Inc 12278 Elastomeric Patch 1 Quart Interior Exterior

Product Description

The DAP INC 12278 is an all-purpose elastomeric patching compound designed for surfaces that are difficult to repair or subject to movement. It delivers permanent flexibility after curing, making it suitable for areas where rigid fillers would crack or fail over time. The compound dries white with a smooth finish, is odorless during and after application, and is fully paintable once dry. It is also water resistant, making it appropriate for both interior and exterior use. Licensed contractors, painters, and general tradespeople working on building envelope repairs or interior finishing work are the typical installers of this product.

This elastomeric patch is well suited for residential and light commercial applications where surfaces experience thermal movement, settling, or minor structural flex. Common uses include patching cracks in stucco, masonry, wood, drywall, and similar substrates that shift seasonally or are exposed to exterior weather conditions. Its all-purpose formulation reduces the need to stock multiple patch products for different surface types. The product is sold in a quart unit of measure and is available in case quantities of six.

Allow adequate dry time before painting, and follow all local building codes for exterior envelope repairs. No power tools are typically required for standard patch application.
