types of waterproofing coating

Waterproofing coatings come in many varieties. These coatings are usually composed of a single layer or a combination of layers. The materials used for waterproofing coatings can range from asphalt to polymer liners, fiberglass, and cementious high-build coatings. Other materials include polymer liners and metal sheet. These are used for many applications, including roofing, siding, decking, and windows. To learn more about the different types of waterproofing coating available, read on.

Protect Your Home Or Business From Deterioration From Moisture

The most common type of waterproofing coating is cementitious. It is the easiest to apply. When mixed with a concrete foundation, cementitious coatings protect the interior and the exterior of a building. The cementitious coating will not expand or contract, unlike other types of coatings. For this reason, it is a good choice for exterior walls, foundations, and even decks. It will protect the structure from water, which can rot and decay.

Another type of waterproofing coating is bituminous membrane. It is a self-adhesive membrane that prevents water from penetrating into the structure. It is made of asphalt, polymers, and filler, and may include certain resins to increase its adhesive properties. One disadvantage of this waterproofing method is its short shelf life. Polyurethane liquid membrane waterproofing is a good option for low-sloped roofs and is expensive.
