Epoxy
Epoxy is one of the most highly recommended and available materials for repair and construction. Typically used with its sister hardeners like fillers, fabrics, and tools, epoxy allows you to complete a multitude of projects.
Epoxy repairs and coats holes and cracks anywhere. It mixes very well with other substances to do anything. Some specific uses include coating, bonding, laminating, and fairing. Applying epoxy to seal surfaces or to reinforce layers will keep your deck, walls, and even boats like new.
Epoxy is like a glue and can bond anything broken to make it new again. If you want to laminate something, look no further than epoxy. Multiple layers over wood or any material can keep structures sealed and covered for years from storms. Another great use of epoxy is fairing. Fill holes and depressions to get a smoothed surface.
