LVT & VINYL Prepare fo
The quality and variety of luxury vinyl tiles (LVTs) and their suitability for a wide range o at subfloor preparation products and floorcovering adhesives manufacturer F. Ball and
F. Ball’s Styccobond F49 Hybrid PS temperature tolerant pressure sensitive vinyl adhesive is used to install LVTs in areas that will be exposed to extreme temperature fluctuations as a result of solar gain.
A long-lasting, visually-attractive flooring finish when installing vinyl tiles or planks involves following basic principles of subfloor preparation, as well as taking precautions to avoid common causes of floor failure. Selecting the optimum products at each stage of the process will also help.
The first step is to check that the subfloor is suitably sound, smooth and dry. To avoid costly floor failure, any laitance and contaminants, including old adhesive residues, should be mechanically removed before proceeding with a flooring installation.
Guarding Against Damp
At this stage, a moisture test should be conducted to determine if the subfloor is dry enough to receive floorcoverings. Excess subfloor moisture, whether residual construction moisture or rising damp, is still the leading cause of floor failure, resulting in costly recalls and delays.

Where relative humidity (RH) levels are higher than 75%, a moisture management solution will be required to prevent moisture attacking flooring adhesives and causing resilient floorcoverings to blister and lift.
Liquid waterproof surface membranes are available that will isolate excess subfloor moisture where relative humidity values are up to 98%, with a single-coat application, and will fully cure in as little as three hours.
Priming
In most cases, the next step in the subfloor preparation process should be to prime the subfloor. When used over non- absorbent surfaces, such as waterproof surface membranes, primers promote adhesion between the subfloor and the levelling compound applied over it. Applied over absorbent subfloors, they also stop the unacceptably rapid drying of levelling compounds.
