Only P4 – P7 chipboard should be used for flooring installations. Ensure the chipboard is securely screw fixed, sound, free from cracks, clean and free from materials which would impair adhesion. Thoroughly vacuum to remove dust. In some instances the chipboard may also need to be primed with a neat coat of UZIN PE 260, please see the UZIN RR 620 data sheet for more information.
Lay out the rolls of UZIN RR 620 underlay parallel to the intended direction of the floor covering with the adhesive side face down. Cut to size before adhering. Keep a several millimetre gap between all vertical structures such as walls. Peel off the protective film then adhere to the chipboard. Once installed roll over the whole area with a pressure roller.
Choose a suitable adhesive for installing the floor covering such as UZIN KE 66 high temperature adhesive for LVT.** Apply evenly onto the underlay using an A2 notched trowel. When the LVT has been installed, rub over the whole area with a pressure roller. UZIN KE 66 is ideal for luxury vinyl tiles as its fibre reinforced to restrict any movement of the tiles.
*UZIN RR 620 is only suitable for P4-P7 flooring grade chipboard and must be free from contamination, sound, load bearing and free from any cracks or deformation. The chipboard may need to be primed with a neat coat of UZIN PE 260 before installing UZIN RR 620, please see the product data sheet for more information.
**Can be used as a high temperature adhesive in most areas. However if a floor covering is being installed in areas with extreme temperatures, for example, a south facing building with large windows which could magnify the temperature, UZIN KE 68 or UZIN KR 430 is recommended. If in doubt please consult our Technical Department.
