The importance of good floor level for flooring installations
Whether you're installing hardwood, laminate, or tile, the levelness of your subfloor can significantly impact the final result. Many installations can fail due to ignorance of the level of the subfloor prior to the installation. Unexperienced floor layers may realise the subfloor level is an obstacle for the installation and risk its durability in the process of fitting anyway. Then when addressing it, it is too late.
Installing flooring on an uneven surface can lead to various problems, including:
Gap Formation: Uneven subfloors can cause gaps between planks or tiles, leading to a flawed appearance and potential tripping hazards.
Adhesive Failure: For glued-down flooring, an uneven surface can lead to poor adhesion, causing the flooring to lift or shift over time.
Locking System Problems: For click-lock flooring, uneven surfaces can prevent the planks from fitting together properly, leading to installation challenges and a compromised finish.
Warping, Cracking, Creaking: Uneven support can cause flooring planks or tiles to warp or bend over time, and they may put additional strain on tiles or planks, leading to cracks or breaks. Wood floors may also creak or make noise if the subfloor is not level, which can be an irritation and reduce the comfort of your space.
A level subfloor contributes to the overall durability and longevity of your flooring.
By ensuring that the surface is even, you provide a stable foundation that helps your flooring withstand the test of time. This stability reduces the likelihood of problems like buckling, gaps, or damage, which can occur when the floor is installed over an uneven surface.
Different types of flooring have specific installation requirements:
Hardwood floors need a perfectly level surface to ensure proper expansion and contraction and to prevent gaps and buckling.
Laminate floors require an even subfloor to ensure the click-lock system works correctly and to avoid future issues with seams and joints.
Old timber subfloors sitting on top of joists, may have issues with level when comprising of uneven floorboards or various timber materials, creating a difference between each other. Subfloors with local differences are usually leveled with 9 - 12 mm plywood or completely replaced with structural plywood or chipboard.
Concrete subfloors with local difference or sloping can be corrected with application of smoothing compounds.
Tile floors need a level surface to ensure that grout lines are even and to prevent cracking or shifting of tiles.
Maintaining a level subfloor is essential for a successful flooring installation. It ensures a smooth, even finish, prevents installation problems, reduces wear and tear, and enhances the durability and longevity of your floors.
By taking the time to achieve a perfectly level surface, you set the foundation for a beautiful and lasting flooring installation that will enhance the comfort and appeal of your space.
