Styccobond F54 from F Ball

F BALL & CO says to ensure a long-lasting, aesthetically-pleasing floor finish is achieved and maintained throughout its lifetime, rubber and linoleum flooring requires the correct preparation of the subfloor, as well as the right specification of adhesive.

As with all flooring installations, subfloors should be clean and thoroughly prepared before a floorcovering is installed. A moisture measurement test should be undertaken to determine the relative humidity (RH) levels of the subfloor.

When RH levels are 75% or above (65% when working with wooden floorcoverings), a waterproof surface membrane (WSM) should be installed to suppress excess moisture within the subfloor. WSMs are readily available in liquid form and can easily be trowel or roller-applied (depending on type) to ensure suitable protection is achieved.

A smoothing underlayment should be then installed to create a smooth and level surface, ready to receive the new floorcovering. Resilient floorcoverings, in particular, are more susceptible to showing up imperfections in the subfloor.

Adhesive selection
An adhesive should then be selected that is compatible with the floorcovering and the intended use of the floor.

Every flooring project presents unique challenges and ongoing research and development has led to the creation of a range of adhesives that meet the needs of modern flooring products and contractors.

A floorcovering manufacturer should be able to advise on suitable adhesives for their products. Alternatively, refer to an adhesive manufacturer’s recommended adhesives guide, which will indicate which adhesive is suitable for the floorcovering in question.

Rubber and linoleum floorcoverings require adhesives with specific properties to suit the different materials’ characteristics and performance.

Rubber floorcoverings
Rubber floorcoverings are widely used and a popular choice for schools, sports settings, and even ships, because they are durable, easy to clean and maintain and offer good grip during wet conditions.

The strong initial tack and high bond strength of specialist rubber floorcovering adhesives such as Styccobond F58 acrylic emulsion adhesive makes them suitable for securing a range of rubber sheet and tile floorcoverings.
Such adhesives will have a high film strength to provide good dimensional stability and prevent the rubber floorcovering from moving in use.

Linoleum floorcoverings
When working with linoleum floorcoverings, F Ball recommends the use of a high-grab adhesive designed to adhere linoleum. Specialist non-flammable, acrylic emulsion adhesives for linoleum floorcoverings, such as Styccobond F54, are solvent free and protected against bio-degradation.

To be able to adhere hessian-backed linoleum floorcoverings, it’s essential the adhesive is able to ‘wet out’ the backing ie transfer enough adhesive to create a good bond and deliver the instant grab that facilitates the installation process by reducing sliding of the linoleum.

The best rubber and linoleum adhesives are protected against bio-degradation and are also approved for marine use, so they can be used in flooring installations on ships and cruise-liners. Adhesives for rubber and linoleum should also be suitable for use over normal underfloor heating.

Outdoor application
For areas subject to high levels of moisture or surface water and areas that are heavily trafficked, it may be preferable to utilise specialist two-part adhesives, such as Styccobond F84, which cures to provide an ultra-strong bond that’s resistant to water, oil and grease. Styccobond F84 is also reportedly suitable for outdoor use.

Because of their individual properties, rubber and linoleum require product-specific adhesives to ensure that a strong, long-lasting bond is achieved between the floorcovering and subfloor. Adhesives with high initial grab also make the installation process that much easier.

In assessing the suitability of an adhesive for rubber or linoleum, consult the floorcovering manufacturer or refer to the adhesive manufacturer’s recommended adhesives guide.
