Wood flooring will contract if the prevailing conditions reduce the product moisture content below 6%. Suitability of use: Suitable for use with under floor heating in commercial and residential applications.Įffects from moisture: Wood flooring will expand if it is exposed to conditions that increases its moisture content beyond 9%. There is no current requirement for slip resistance in residential developments. UV Oiled Finish results: DRY (60) LOW RISK WET (45) LOW RISK Slip Resistance: Tested to BS 7967-2: 2002 (Pendulum Test in PTV values) Requirement: Less than 3 ppm Result: 0.0053 ppm Release of Formaldehyde: Class E1 | EN 717 – 1:2006 Result 0.014 mg / m3 Thermal Conductivity: EN ISO 10456 / EN ISO 12664 Result 0.15 W / (mk) ![]() Moisture Content: EN 13183 – 1 Requirement: 6% to 9% Average Results: <7% Thermal Conductivity: EN ISO 10456 and EN ISO 12664 Result 0.15 W/(mk) With an open time of approximately 60 minutes this product is also ideal for use in large areas.įire Protection: Reaction to fire – wood flooring performs to EN 13501-1 Dn s1 SW 890's formulation is completely water & solvent free, this eliminates the possibility of timber planks warping or cupping due to VOC's. This adhesive maintains an elastic hold to accommodate the differential movement associated with changing climatic conditions. SW 890 is a high quality wood floor adhesive for bonding timber floors to all common substrates. 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.
