Floor Preparation


When Your Sub-Floor Needs Work

The finished appearance of a vinyl floor will only be as good as the quality of the base over which it is installed. Any irregularities in the sub-floor will show through the finished floor. Careful sub-floor installation as per AS 1884-2012 is vital for an excellent floor appearance and good preparation. To ensure a successful installation of your new LVT floor, it is important that the sub-floor is hard, flat, smooth, clean, dry and free from defects, contaminants and fit for purpose.

Here are some guidelines for preparing your sub-floor.

Cracked, Uneven Concrete

It is important to thoroughly sweep or vacuum your floor prior to using adhesive and STICK LVT flooring.


Cracks and other imperfections must be filled and floor leveled with a screed. Once completely dry, the surface is sanded for a smooth, level result. A skilled tradesman can detail the work required for your floor. Extensive floor preparation is required for a STICK LVT.

Ceramic & Porcelain Tile

Usually tiled floors are level and relatively smooth however wide grout joints and chips can show through an LVT floor. Therefore ensure the floor is in good condition before you begin installing LVT.

Ensure that the floor is sound and firmly fixed and any loose or powdery material removed from the joints. Check for loose, cracked or broken areas of ceramic tile. The surface should be prepared with a light grind to remove any surface contaminations and any cracks cleaned out and filled with a suitable resin bonded cement / sand mixture. In most instances, a smoothing or levelling compound of at least 3mm thickness must then be applied to provide surface porosity for acrylic adhesives prior to installation of the LVT.

Information of the best method to prepare a ceramic or porcelain tile floor should be sought from primer and levelling compound manufacturers.

Wooden Floors

One of the unfortunate characteristics of real timber floors is the potential for planks to shrink, bow and lift, creating an uneven surface. Wood can also splinter and scar. Left in this condition, LVT will not perform on top.

The correct timber sub-floor preparation is to secure any loose or lifting planks, followed by sanding to bring the floor back to an even, level and smooth surface. Without sanding properly, timber substrates can have high and low spots throughout the floor that can show through the LVT.

Old worn out timber floors (see picture above) need Masonite panels as underlayment. You will need a skilled tradesman to help you.
