How can new floor coverings be safely installed over old floor finishes or over damp or contaminated surfaces?

Substrates that have, for example, high residual moisture content or contamination from oil and grease usually require laborious and expensive surface preparation. This work can be avoided by using the stabilising underlay UZIN RR 185. The underlay has slip-resistant foam studs on the underside that separate the top covering from the substrate. Between the underlay and the substrate, there is a thin air-layer; traffic over it creates a pump-effect so that moisture can escape at the edges. High residual moisture no longer has a damaging effect on the flooring construction. As the stabilising underlay is loose-laid, the flooring construction can be easily removed, leaving no residue, at a later date.

<p>Lay out the stabilising underlay parallel with the proposed direction of the covering and roughly cut in. (Off set the side-seams in the underlay from those in the top covering by at least 25 cm).</p>

<p>Against vertical structures such as walls and door-frames, leave a gap of at least 3 mm. Accurately cut in the ends and edges with a hooked blade.</p>

<p>The side-seams of the sheet must not be cut. Under the joints, a paper strip can be laid so as to avoid bonding of the underlay to the substrate.</p>

<p>Then the installation of the top covering can begin immediately. Lay out the covering, roughly cut in the ends and accurately cut in the edges. Pull back the sheet half way and, using a notched trowel suitable for the backing structure of the covering, evenly spread the UZIN dispersion adhesive.</p>

<p>For dense coverings, such as PVC sheet, UZIN KE 2000 S (with a long open time) is especially suitable. The method for installing the second half of the covering is identical.</p>

<p>Using a cork block. Rub down the installed covering. Recommendation for ventilation of the substrate: fit ventilated skirtings onto the top covering. Textile, PVC and cushioned vinyl coverings can be installed. The limit for point-loading is 3 N/mm².</p>
