Damp/Wet Tolerant Sealants
A selection of sealants that are either waterproof in nature when cured or tolerant to damp or wet substrate conditions when applied. There's even a small selection of sealants that can actually be applied under water such as the popular hybrid polymer mastic sealants CT1 by C-Tec & Everbuild's popular Stixall sealant adhesive. The materials used for this sort of application are usually hybrid polymers, polyurethane or epoxy based and come in both 1-part cartridge form and 2-part tin or pack form.
