The adhesive can be used for installation of jointless wood flooring, for T&G and Click flooring without limiting the thickness of hardwood planks.

Adhesive requires no preparations and ready for use, easy to spread and make even, cures fast.
Recommended for installation of wood floors over radiant flooring heating systems.

BASE REQUIREMENTS

It is allowed to use the adhesive on the following bases: prepared concrete surface, cement screed, sulphate-calcium screed, ceramic tile, plywood, chipboard, rough board floor, synthetic or cork subfloors and similar bases.
Base shall be hard and even, solid, clean, dry, dedusted and degreased. Paint, fat stains and other weak coatings shall be removed.
Base surface shall not exceed 4%.

APPLICATION

Open the bucket with adhesive, remove the tinfoil and the glue film from the surface, if any.
Apply the hardwood flooring adhesive to the base to the surface of 2-3 planks and distribute it evenly using the notched trowel. Keep the trowel at the angle of 90° to the surface. This position will allow you to distribute the glue evenly and uniformly.
Apply some pressure to hardwood flooring planks to put them into place. Keep the bottom plank surface covered with adhesive all along its surface.

After the installation of planks it is recommended to lift the plank to see if the bottom surface is completely covered in adhesive. If necessary, planks can be driven to the end point by a rubber mallet.
After applying the adhesive it is necessary to install the hardwood planks within 60 minutes. Otherwise, the film that decreases adhesion features will appear on the adhesive surface.
In case of contact of adhesive with the front surface of hardwood flooring planks clean the adhesive remains immediately using rags and Coswick hardwood flooring heavy duty cleaner.
During breaks and when installation is finished close the bucket tightly, if any adhesive left for future use.
