People Also Ask

FLEXPATCH™ is a waterproof elastomeric wood filler, caulk, and sealant designed to repair and seal cracks, holes, seams, valleys, low spots, and other areas vulnerable to water intrusion. It is ideal for repairing wood surfaces before painting, but it also adheres to many other materials including concrete, masonry, metal, fiberglass, and roofing substrates.

Yes. Once FLEXPATCH™ has cured, it can be top coated with most latex paints and acrylic coatings such as DECK GUARDIAN™. For best long-term performance, FLEXPATCH™ should not be left exposed and should always be protected with a compatible finish coat after it has dried.

FLEXPATCH™ bonds to a wide variety of properly prepared surfaces including wood, plywood, siding, concrete, masonry, primed metal, galvanized steel, aluminum, fiberglass, slate, clay and concrete roof tiles, EPDM, and many other building materials. Its flexible acrylic formula makes it suitable for both horizontal (non-ponding) and vertical applications.

FLEXPATCH™ is formulated for minimal shrinkage and excellent flexibility. It dries to a durable, waterproof seal that resists cracking under normal movement. For deep repairs larger than about one square inch, multiple thin applications are recommended to achieve the best results and allow each layer to cure properly.

FLEXPATCH™ is ready to use directly from the container—do not thin it. Apply it with a stiff brush or trowel to clean, dry, properly prepared surfaces. Under normal conditions it becomes tack-free in about 2 hours, can typically be coated after approximately 12 hours, and fully dries within 5 to 24 hours depending on application thickness, temperature, and humidity. Clean tools with warm soapy water before the product dries.
