Gypsum concrete is a durable subflooring material that handles the weight of different types of floors, helping them last longer. When experts install this material properly, it is functional and has a smooth finish. Here are five tips for adding flooring over gypcrete:
Prepare the Surface Properly
Clean the installation surface using a broom to remove loose dust, dirt, debris, and other particles. You can use a vacuum to remove any remaining dust particles that may affect the concrete’s adhesion. For stubborn grime, use a mop and gentle cleanser to create a clean surface.
During the preparation process, installation professionals inspect the floor’s surface for cracks, holes, or other structural issues. If they find gaps and cracks, they use patching products to fill them, creating an even floor. If there are high spots on the floor, they level them using a concrete grinder.
Check Moisture Levels
Checking the concrete for moisture before installing new flooring allows the gypcrete to dry properly, preventing issues such as mold growth, adhesive failure, or damage to your new flooring. Dark spots, discoloration, or a powdery residue are some common signs your surfaces are still damp. If you touch the area and it’s wet, the material requires more time to dry.
Experienced installers use a moisture meter to determine if the gypsum concrete surface is wet or dry. They can also place a plastic sheet on the surface and tape down the edges to test for moisture. If condensation develops under the plastic, it shows that moisture is present in the concrete. Applying a moisture barrier or sealant once the gypcrete is dry helps shield against future dampness issues under your flooring.
Apply a Suitable Primer
Qualified installers choose a primer made specifically for gypsum concrete surfaces. The right primer is suitable for use with the gypsum slab and the flooring material they plan to install. A paint roller works well for applying an undercoat to the entire concrete surface.
For edges and corners, use a brush or an edging tool to cover all the areas effectively. Some primers may require multiple coats for even coverage. Allow the primer to dry completely and disperse any fumes before entering the area. To speed up this process, open windows or use fans to circulate fresh air.
Choose the Right Flooring
Floors such as laminate, engineered wood, and vinyl are compatible with gypsum concrete underlayments. Carpet can be installed if you prefer a softer feel underfoot. The lightweight and sound-proofing nature of gypsum concrete reduces noise transmissions to rooms below, regardless of the flooring type you choose. This helps create quieter spaces in residential and commercial buildings.
Ceramic tile flooring provides a non-porous layer above the concrete, preventing water transfer. Adding a cushioned membrane between the concrete and the tiles provides a more cushioned floor and helps prevent cracks in the tiles. This layer helps the tiles stick to the underlayment more easily and makes the flooring resilient to heavy foot traffic.
Leave Space for Expansion Gaps
Some flooring materials, such as those made of natural wood, expand and contract when temperatures and humidity levels change. Without sufficient space for movement, the flooring may bend, twist, or crack. These materials also require time to adjust to the environment where experts have installed them. Expansion gaps allow the flooring to get used to changes in interior conditions without getting damaged. Installers leave small spaces around door frames, vents, and other fixed objects to allow for continued expansion. These gaps are typically covered by baseboards and vent covers.
