Dap 7079880832 Polymer Sealant Siding Window

Product Description

The DAP 7079880832 is a polymer-based sealant formulated for siding and window applications. Part of the DynaFlex 800 Advanced product line, this sealant is designed to form a flexible, weather-resistant seal at joints and gaps common in exterior building assemblies. It is suited for use on a range of substrates typically found around window frames, door casings, and siding transitions. Contractors, carpenters, and general tradespeople apply this product during new construction and renovation work where long-term joint movement and moisture exclusion are primary concerns.

This sealant is applied to exterior joints at the interface of siding panels, window frames, trim, and adjacent building materials. It performs in conditions where thermal expansion and contraction create ongoing movement at sealed joints. Typical install scenarios include perimeter sealing of window and door rough openings, lap siding joints, and trim-to-sheathing transitions on residential and light commercial exteriors. No specific compatible system or replacement part number is stated in the product data.
