Gypcrete is a cousin to concrete and made of a lightweight sand mixture that makes it much lighter than concrete, though less durable. Only certain types of flooring can be laid over the top of a Gypcrete subfloor, which is laid down over a wood subfloor.
Herein, what is Gypcrete used for?
Gypcrete or gypsum concrete is a popular building material used as a floor underlayment. It is commonly used in wood-frame and concrete construction for fire ratings, sound reduction, radiant heating, and floor leveling. Chemically it is made up of gypsum plaster, Portland plaster, and sand.
Similarly, it is asked, how thick is Gypcrete?
Minimum Thicknesses: The minimum pour thickness over wood framed floors is ¾” thick. In some cases the pour thickness can be reduced to ½” thick if reinforcement is used. Weight Considerations: Gypsum Concrete weighs approximately 6.5-7.5 lb/sf at ¾” thick and 13-15 lb/sf at 1-1/2” thick.
How to Install Gypcrete
- Install gypcrete after placing up the drywall.
- Replace any damaged boards if installing gypcrete on a wood subfloor.
- Pour 1/2 inch of gypcrete onto concrete, or 3/4 inch of gypcrete over tongue-and-groove wooden subfloor with 16-inch to 24-inch truss or beam spacings.
