A 4L tin of Portugal Cork Trade Contact adhesive typically covers approximately 40 square metres (based on the standard coverage rate of 10 square metres per litre). Keep in mind that as a contact adhesive, it must be applied to both the subfloor and the back of the cork tile, so you should calculate your total surface area accordingly to ensure you have sufficient product for a double-sided application.

To achieve a professional bond, ensure both surfaces are clean, dry, and free of dust or grease. Apply an even layer of the contact adhesive to both the subfloor and the back of the cork tiles using a brush or fine-notched spreader. Allow the adhesive to become “touch-dry” (usually appearing glossy and tacky) before firmly pressing the cork into place. For maximum adhesion, it is recommended to use a floor roller immediately after installation to eliminate air pockets and ensure full contact.
