Weatherproof Sealants

(14 products)

Weatherproof sealants are perfect for outdoor use as they are designed to withstand UV, weather and water exposure. Some have to be applied in dry conditions, whilst others can be applied in wet conditions. Once applied they remain flexible and some weatherproofing sealants are paintable. Suitable uses include building, roofing and ductwork applications. A large range of top brands are available, as well as water based silicone, low odour and solvent-free options.
