Fillers and Putty

POR-15 putty fillers are paintable non-shrinking professional-grade products that are easy enough to use for DIYer projects. The POR-15 Patch seam sealer remains flexible and is great for filling gaps, joints, and small holes. POR-15 Epoxy Putty hardens like steel and is strong enough that you can drill and tap. Epoxy Putty can stick and cure on wet surfaces and can be used to smooth small uneven surfaces caused by screw holes, scratches, or coarse materials.
