RESILIENT FLOORING SELECTING THE BEST
Contractors installing vinyl floorcoverings face a potentially confusing array of adhesives to choose from. These include adhesives with special features such as temperature tolerance, pressure sensitive characteristics and water resistance. Neil Sanders, technical director at F. Ball and Co. Ltd., provides a straightforward guide to choosing the optimum vinyl adhesive.
Standard, wet-lay adhesives are available for installing practically any type of vinyl sheet or tile floorcovering. The contractor simply applies the adhesive evenly over the subfloor using a trowel and allows it to dry slightly before placing the floorcoverings and finally rolling to ensure good overall contact.
There are also situations where it may be desirable, or even highly recommended, to use an adhesive with specialist properties. Adhesive selection should be based on the specifics of a flooring installation, and it is always advisable that contractors check the compatibility of adhesives and particular floorcoverings.
VINYL TILES OR PLANKS
While wet-lay adhesives are fine where an immediate bond is not required, pressure sensitive adhesives are often the best choice for installing vinyl tiles or planks. They form an instant grab upon contact, so contractors don’t need to worry about tiles or planks moving about when they are working, making them ideal for where intricate designs or patterns are being created.
Nowadays, pressure sensitive adhesives are available with a range of additional features, including temperature tolerance, for use where vinyl floorcoverings will be exposed to temperature fluctuations, such as conservatories and areas where floor to ceiling windows result in solar gain. Over time, extreme temperature fluctuations will cause vinyl floorcoverings to expand and contract, which can lead to tenting and gapping at the edges of floorcoverings if a suitable adhesive isn’t used.

MOISTURE TOLERANCE
When installing flooring in an area subject to high levels of humidity or surface water, an adhesive with water resistant properties is essential. An adhesive that isn’t water resistant

F. Ball’s Styccobond F49 Hybrid PS is an example of a new breed of high-performance, hybrid adhesive, with revolutionary combinations of properties, including temperature tolerance, moisture resistance and pressure sensitive characteristics. The water-based adhesive has the familiar characteristics of a pressure sensitive adhesive and develops the extremely high bond strength required to hold vinyl floorcoverings firmly in place in areas exposed to extreme temperature fluctuations (from -20C to +60C). The properties of this adhesive also make it moisture resistant, meaning it is suitable for installing vinyl floorcoverings in damp and humid environments.
