National Deck and Stair specializes in the applications of waterproof deck and stair coatings. Our main applications are multilayer fiberglass coatings such as Desert Crete. We also are one of the largest installers of magnesite flooring. Magnesite is a magnesium oxychloride form of cement that is waterproof and has been in use since the early l920’s.

Our waterproofing applications are widely used on decks, balconieswalkways, staircases and pool decks. A number of finishes and textures are available ranging from smooth to heavily textured, knockdown finishes, skip troweled finishes and stenciled patterns. You have a lot of colors to choose from, and custom colors can be easily made to suit your application. We also install precast tread replacements and iron based precast stairways, as well as metal railings, fencing and gates. If we can be of service please give us a call. We look forward to hearing from you.
