Deck repair and maintenance benefit greatly from a whole range of low-VOC polyurethane-based formulations that have come out of manufacturers’ labs, offering flexibility, high-performance and enhanced aesthetic capabilities. These liquid-applied single-component deck coatings are moisture-cured, slip-resistant and very suitable for waterproofing low- to high-traffic or pedestrian areas.
There are various deck coatings products used in the complete and correct application of the deck coatings system. The primary material is the low-VOC polyurethane deck coatings whose main use is for waterproofing the deck membrane, commonly a one-part and self-leveling formulation that interacts with sand aggregates. Another deck coatings material is the two-component and solvent-based epoxy primer used for preparing concrete and metal deck surfaces before the actual coating application.
A single-component and non-staining polyurethane sealant is also used in deck coatings systems. The polyurethane sealant becomes rubber-like when cured at the right temperature, making it very flexible and tear-resistant. For increased slip- and wear-resistance, sand aggregates are broadcasted at every layer of deck coatings application. A polyurethane top coat completes the deck coatings system for added protection from ultra-violet exposure.
