Polyurethane sealants are a quick drying and moisture-cured sealant that is used in many industries including building, construction, and the automotive industry. It is generally used for sealing joints in walls and floors. It works well on concrete, and it also seals and bonds fiberglass panels.

Usage

When polyurethane sealant dries, it produces a very tough elastic-type seal. It also seals and sticks well to masonry, wood and metals. It is highly compatible with plastic and rubber. Urethane sealant is a clear interior sealant mainly used on floors like terracotta tiles. Polyurethane can harden much quicker than urethane and it can be used to mend vehicles, especially those made from fiber glass. It seals and mends fiberglass extremely well, creating a very strong bond.

Resistance

Polyurethane sealant proves to be an excellent resistor of water and ultra-violet radiation. It offers a permanent elasticity in all weather conditions. Urethane sealants are more designed for porous materials such as concrete, slate, and terracotta. It is highly protective in heavy traffic areas and resistant to grease, oil, gasoline and food splashes.

Indoors and Outdoors

Polyurethane sealant is recommended for decking and flooring because it works better on outdoor and weathered surfaces. It is not at all recommended for use with glass and it is not recommended for use on joints with movement greater than 25 percent.
