VINYL & LVT to Stick To
s to consider when installing LVT flooring and why selecting the right adhesive is rface success.
allows floorcoverings to be lifted and repositioned in the initial stages of drying, making it a great choice for installing tiles and planks, intricate patterns and bespoke designs that need precise alignment.
Since its launch, Styccobond F49 has also been approved for installing vertical flooring accessories, such as skirting, capping and coving. This means it offers an alternative to contact adhesives and allows you to use one adhesive to install both floorcoverings and flooring accessories. Unlike contact adhesives, the hybrid adhesive only needs to be applied to one surface and the same properties that make it ideal for creating intricate designs allow for the repositioning of vertical flooring accessories during the early stages of drying. Styccobond F49 is also resistant to water, allowing it to be used in areas subject to water and high humidity, including wet rooms.
It is highly recommended to check the compatibility of particular floorcoverings and adhesives. To do this, fitters should consult the adhesive manufacturer’s Recommended Adhesives Guide or see the floorcovering manufacturers’ instructions.
Prior Preparation
Just as important for ensuring flawless results when installing LVTs is subfloor preparation, and the first step in

any floorcovering installation should be to make sure that the subfloor is suitably sound, smooth and dry. This should involve a moisture test to determine subfloor relative humidity (RH) levels. Where RH levels within the subfloor are above 75%, a moisture management solution, such as a waterproof surface membrane, will be required to prevent excess subfloor moisture attacking floorcoverings and adhesives, causing LVTs to debond. This is still the leading cause of floor failure.
Following this, the application of a heavy-duty levelling compound with high compressive strength and excellent self-levelling properties is recommended to create a perfectly smooth base for the installation of LVTs, preventing imperfections in the subfloor shadowing through floorcoverings.
In most cases, the priming is required beforehand to promote adhesion of the chosen levelling compounds and stop the rapid-drying of levelling compounds when applied over absorbent subfloors. It also prevents pinholing, caused by tiny bubbles resulting from the slow escape of air from the subfloor, which burst on reaching the surface, leaving small pinholes or craters as the levelling compound cures and can affect the appearance of final results.
Only after following these steps, should floorcoverings be installed using a chosen adhesive.
