The SW890 adhesive is an Elastic adhesive with a movement accommodation factor (MAF) of approximately 300% of the adhesive bed thickness. As such it distributes and lowers all shear stresses caused by expansion and contraction across the entire surface area of the adhesive, thus avoiding high stress peaks which normally form at the edges of boards with rigid adhesives causing premature failure. In this way the Elastic SW890 will withstand excessive movement and stress caused by changing climatic conditions throughout the seasons.
SW 890 is a high quality wood floor adhesive for bonding timber floors to all common substrates. This adhesive maintains an elastic hold to accommodate the differential movement associated with changing climatic conditions.
SW 890's formulation is completely water & solvent free, this eliminates the possibility of timber planks warping or cupping due to VOC's. With an open time of approximately 60 minutes this product is also ideal for use in large areas.

I HAVE UNDERFLOOR HEATING
Any type of underfloor heating system must be tested and commissioned before you consider installing any timber floor. You then turn it off before installing any floor.
I HAVE A VOID UNDER MY OLD FLOORBOARDS AND WANT TO INSTALL NEW FLOORING ABOVE
The best way is to remove the old floorboards and then check the joist and the base floor and make sure that the bricks or other method of allowing air to circulate underneath as free form debris and other obstacles. You can then add insulation between the joists using “hangers” and then fix a 20mm structural board direct to the joists. An alternative method is to screw marine plywood to the joists and then fully bond a 15mm engineered board which can also be herringbone or chevron. Parquet herringbone and chevron cannot be fitted to joist as it needs a plywood or chipboard subfloor.
CAN I PUT WOOD FLOORING IN A KITCHEN/BATHROOM?
Yes, wood flooring can be fitted in any part of your home. Remember that wood flooring is a natural product and will react differently compared to man-made or stone tile options. Discuss care and maintenance advise with our experts prior too fitting in high spillage areas.
WHAT DOES CHARACTER MEAN?
The term character can be applied in two ways with wood flooring. The first is referring to the aesthetic properties of the wood e.g. grain pattern, knots etc… the ‘character’ of the timber. The other meaning of this term is as a grade description, i.e. ‘Character Grade’ this denotes a way to visualise the grading specification. Character grade usually has a wider grain, with larger and more frequent knots permissible than a ‘select’ grade, but not as much as a ‘rustic’ grade.
HOW LONG BEFORE I HAVE TO SAND IT AND RE FINISH?
This will depend on a number of factors unique to where the flooring is fitted. Typically, if the floor is well maintained and cleaned with the correct products, the finish should last for many years, possibly a lifetime depending on usage. If a wood floor has not been properly maintained or is in a very heavy use environment, then you need to watch out for indicators that the finish is in need of maintenance. These indicators are typically: • How quickly the wood floor is getting dirty/how easy it is to clean any soiling off? • Does the wood feel rough? (not application to band sawn flooring) • Does the floor look patchy? • Has a chemical cleaner been used or spilt on to the floor? If the answers to these questions are that it is hard to clean and looks/feels rough/patchy then it might be time to consider re-oiling. It is always best to get in touch with us first to discuss and sanding may not be required.
