Installing Gypcrete Over Uneven Subfloors

Gypcrete or gypsum concrete can be a practical solution to create a level surface for flooring applications. Trained and certified businesses can install the product on uneven subfloors for better results. Professional installation also boosts adherence to industry standards and regulations.

The Process

The first step is to identify high or low spots on the surface and address them before Gypcrete application. A professional then sands or grinds to address the unevenness on the subfloor. To contain the gypsum concrete, experts install edge barriers like foam or adhesive-backed tape around the perimeter of the installation area. The next step is to mix and pour the gypsum concrete onto the subfloor. A professional spreads and levels the product on the subfloor using a leveling tool. Allow for drying and curing before installing the flooring material for a better outcome. 

The Benefits of Gypsum Concrete

Gypsum concrete is a product of cement, water, and sand mixed together. Installing gypsum concrete after preparing the subfloor can offer the following benefits:

Leveling Functionalities

Gypsum concrete is a self-leveling material that can create a smooth and uniform surface. The product can fill in low spots and even out uneven areas, providing a suitable foundation for various types of flooring installations. Licensed applicators pour the topping material on subfloors with irregularities to attain level surfaces. When mixed with water, the product flows across the subfloor, filling low areas and depressions.

Sound-Control Properties

Gypcrete has sound-dampening elements that help reduce airborne and impact noise transmission between floors. This feature can provide a quieter and more comfortable living or working environment. Choose gypsum concrete with high sound transmission class and impact insulation class ratings to benefit from the noise-control properties. The material also helps absorb and dissipate the energy produced by footsteps, dropped objects, and furniture movement in buildings.

Lightweight and Durable

Gypsum concrete is more lightweight than traditional concrete, making it easier to handle and transport. The lightweight feature reduces the overall load on the building structure, making it suitable for applications where weight is an issue. The material also has good crack resistance, lowering the risk of developing fissures over time. This characteristic helps maintain the integrity and durability of the floor surface, reducing the need for repairs or maintenance.

Compliance with Building Codes

The product should comply with building codes and regulations when installing gypsum concrete. Choose gypsum concrete with approvals from the International Code Council Evaluation Service (ICC-ES) and the U.S. Department of Housing and Urban Development (HUD). ICC-ES and HUD approvals show that the product has undergone meticulous testing and evaluation to adhere to building codes and rules. Complying with such standards can avoid legal and regulatory problems associated with using poor-quality materials.

Quick Drying

Gypsum concrete dries and cures faster than other floor underlayment materials. Depending on the ambient conditions, it can be ready for foot traffic in several minutes to a few hours. This quick drying time contributes to the efficiency of the installation process and minimizes project lapses. The faster drying period in gypsum concrete can reduce downtime for commercial and high-traffic spaces. In many cases, the curing or drying time can depend on the humidity and temperature levels in a building. 

Get Quality Gypcrete

The self-leveling properties of Gypcrete make it easier to install over uneven subfloors. Due to its fluidity, the product can allow for installation over a large area. Experienced applicators apply a thick layer of gypsum concrete to compensate for the subfloor irregularities. Gypsum concrete is compatible with hardwood floors, radiant heating systems, concrete subfloors, and acoustic underlayment materials. Invest in quality products that meet building codes and regulations.
