FLOOR PREPARATION

Why is floor preparation important?

Floor preparation is an essential step in preparing a subfloor for new flooring. It ensures that the surface is flat and even, which is necessary
for not only the overall appearance, but also to achieve a more durable floor.

In recent years, wood and tile flooring have become larger, longer, and thicker. This has made it more important to have a flat and level subfloor.

Flooring installers must install wood, engineered hardwood, laminate, and tile flooring on a flat surface. If the subfloor is uneven, it will force the wood planks to bend and change shape, which can cause them to warp, split, separate, develop bumps in high areas, and become soft and spongy in low areas. Tiles will not line up edge-to-edge and may crack. Additionally, the baseboards will have gaps at the bottom if the subfloor is not level.

All hardwood floor manufacturers require that the subfloor be flat within 3 mm per 3 metres tolerance. This means that the subfloor must be smooth and free of bumps and dips, or it may void the manufacturer’s warranty if you make a claim for defects.

Here are some of the benefits of floor preparation:

Improved quality, durability, and safety
Extended lifespan
Enhanced appearance

How is floor preparation done?

The specific floor preparation process will vary depending on your subfloor type. However, the general steps are as follows:

Inspect the floor: Use a laser level to determine the high and low spots on the floor.

Prepare the surface: Clean the floor and remove any debris. If necessary, patch any holes or cracks.

Apply a primer: This will help the levelling compound to adhere to the subfloor.

Pour the levelling compound: Start at the highest point and pour the levelling compound into a thin layer. Use a screed machine to spread the compound evenly.

Allow the compound to dry: The drying time will vary depending on the type of levelling compound you use. Once the
compound is dry, you can install your new flooring.
