| Deck Coatings The ingress of water and chloride ions into the structural concrete and reinforcing steel of parking and bridge decks or suspended slabs can cause serious structural damage. One preferred way of stopping water penetration on these types of structures is the application of a coating that is flexible and durable enough to withstand the movement, expansion/contraction and vehicular traffic. These types of coating are known as Deck Coatings.Deck Coatings can be defined as 'A pigmented coating designed for application to horizontal surfaces such as decks and porches. In most cases a coarse aggregate is added where slipping is a concern.' Deck Coatings can be divided into two main catagories: Vehicular Traffice Deck Coatings This system is applied to concrete decks to prevent water from entering occupied space below, and to protect the surface to which it is applied from damage by water and salts, while providing a slip-resistant, attractive wearing surface. This system is suitable for surfaces subject to vehicular and heavy pedestrian traffic. It consists of numerous components, that together form a system with optium performance. The top coat is available in limited fade-resistant colors. The most common are: Gray, Charcoal Gray and Tan. Pedestrian Traffic Deck Coatings This system is used for waterproofing concrete balconies, plaza decks, terraces and other areas subject to pedestrian foot traffic. Usually consists of one-part polyurethane Base Coat and a one-part aliphatic polyurethane Top Coat with an aggregate added between coats to provide a safe, slip-resistant, attractive walking surface. The Top Coat is available in various fade-resistant colors. |
