Stucco Lite HM is a non-insulated wall coating system for high moisture areas, specifically designed to control and prevent vapour diffusion from the high moisture environment into the adjacent structure. The system consists of an exclusive cementitious trowel applied vapour barrier coating glass fibre reinforcing mesh, topped with base coats, and a finish texture coat which can be selected from any one of the available Durex® Architectural Coatings.
- Excellent vapour control system
- Easy to apply
- Allows for use of a wide variety of finish textures
- Impact resistant
- Applicable for new and existing construction
Stucco Lite HM system can be used for both new and restoration work. It is highly recommended for use in high humidity areas, especially swimming pools, indoor water parks and high moisture areas.
