DAP® ALEX FLEX® PREMIUM MOLDING & TRIM ACRYLIC LATEX SEALANT is specifically formulated for use on molding and trim applications. It delivers excellent adhesion and flexibility for a crack proof seal. The high-performance formula is ideal for sealing natural and synthetic materials such wood, MDF, PVC, polystyrene and composite molding. It provides smooth and easy application and tooling, low odor, and water clean-up. In just 30 minutes, the sealant forms a tough outer skin that's dry enough to paint over with latex or oil-based paints, saving time. It provides a long-lasting, durable seal that will not shine through or discolor paint. ALEX FLEX® is ideal for achieving a professional look with paint projects when sealing gaps around trim, crown molding, chair rails, baseboards, windows and doors. 60 Year.

Product Application:
Apply in temperatures above 40ºF. Do not apply when rain or freezing temperatures are forecasted within 24 hours. Cooler temperatures and higher humidity will slow down dry time.
If using the squeeze tube, remove cap.
Cut nozzle at 45º angle to desired bead size.
If using the cartridge, load into caulk gun.
Fill gap or joint with sealant.
If necessary, tool or smooth the bead of sealant with a finishing tool before the sealant skins over.
Clean up excess wet sealant with a damp sponge before it skins over. Excess dried sealant must be cut or scraped away. Clean hands and tools with warm water and soap.
Allow sealant to dry at least 30 minutes (longer in cool or humid conditions) before painting with latex or oil-based paints.
