How can wood flooring be securely installed on substrates requiring restoration? WITH UZIN MK 250 AND UZIN MULTIMOLL SOFTSONIC 3 MM.

Wood flooring can be bonded to substrates requiring restoration with the help of the insulating and stress-relieving underlay UZIN Multimoll Softsonic 3 mm and the 1-component premium wood flooring adhesive UZIN MK 250 in the system. UZIN MK 250 is a wood flooring adhesive of the next technology generation. It offers a broad properties profile, universal use and suitability for the bonding of all common wood flooring types, grades and formats, on all system substrates.

The substrate must first be sanded with a WOLFF grinding machine to remove loosely adhering spots. Next, the area must be cleaned from sanding dust and other dirt using a powerful vacuum cleaner.

Apply the 1-component PUR rapid primer UZIN PE 414 Turbo with a UZIN nylon fibre roller very thinly onto the substrate. Depending on the substrate and the application amount the priming coat should have set after roughly 12 hours (when using approx. 80 - 150 g/m²).

Apply UZIN MK 250 with a notch size B 3 onto the substrate along a reference line.

Apply UZIN Multimoll Softsonic plates with the printed side facing up in half-offset fashion to the fresh adhesive bed, cut the edge zones and press down immediately with a segmented roller over the whole area. Maintain a distance of 3 mm to all upright structures. Please note that the installation direction of the UZIN Multimoll Softsonic plates runs perpendicular to the installation direction of the subsequent woodflooring installation.

Apply UZIN MK 250 with notch size B 11 onto the UZIN Multimoll Softsonic.

Place the wood flooring with a slight sliding motion into the adhesive bed and press down. Ensure full wetting of the back of the wood flooring. The area can be sanded and is ready for traffic after 48 hours (at 20 °C and 65 % relative humidity).

UZIN MK 250 is the first choice for everyone who does not enter into any compromises.
