Use a notched trowel to spread the adhesive evenly, creating a consistent layer that will securely hold the cork tiles in place. Be sure to allow the adhesive to become tacky before laying down the tiles to ensure a strong bond.

When laying the cork tiles or planks, start from the center of the room and work your way outwards. This will help to ensure that the tiles are evenly distributed and any cuts or adjustments needed around the edges are minimized. Use spacers to maintain consistent gaps between the tiles or planks, allowing for expansion and contraction. Press each tile firmly into place, ensuring good contact with the adhesive or underlayment.

Cutting cork tiles or planks to fit around obstacles or along the edges of the room may be necessary. Use a sharp utility knife or a jigsaw with a fine-toothed blade to make clean, precise cuts. Measure carefully and cut slowly to avoid damaging the cork. Fit the cut pieces into place, ensuring they are properly aligned and secure. Take your time with this step to achieve a professional finish and avoid gaps or uneven edges.

Once all the cork tiles or planks are in place, allow the adhesive to cure fully before walking on the floor. The curing time can vary depending on the type of adhesive used and the environmental conditions. Follow the manufacturer’s instructions for curing times to ensure a strong bond. After the floor is fully cured, remove any spacers and install baseboards or moldings to cover the expansion gaps and give the floor a finished look.
