What are the recommended sealants I should use with PVC trim?
Jun 27, 2018



As with adhesives, look for products that contain some type of solvent. NPC Solar Seal #900 Sealant/Adhesive in Trimboard white #111 has been found to be one of the best sealants for sealing and bonding PVC trim to itself, as well as many other substrates. Other recommended sealants include Quad and EP-1000 Enhanced Polyurethane by OSI, and Geocel 2300, or other polyurethane sealants. Do not use silicone sealants, as they are not compatible with cellular PVC trim.
