Wall Tiles Design Aspects
Combining undeniable acoustic and thermal qualities, cork brings a warm and colourful touch in all interiors. Environmentally friendly, flexible, durable, water resistant and easy to install and maintain, cork is the perfect material for walls.
PREPARATION OF THE SUPPORT
Packaged tiles, adhesive and varnishes should be acclimatised on-site for at least 24 hours before installation. Remove the tiles from packaging just before spreading the adhesive.
Cutter, ruler, pencil, chalk line, roller, rubber mallet.
Ensure that, as far as possible, material from the same batch is used in the same area. Before installation, please control the tiles. If you come across a defect in production, please register the complaint at your supplier immediately and do not install! When checking the cork tiles, keep in mind that you are dealing with a natural material. The tiles may have slight variations in colour or structure. They contribute to the charm and originality of a cork wall covering. To achieve the most pleasing blend of shades, shuffle tiles from different packs before laying. Check if there are small differences in size between the different tiles. If this is the case, it is better to group the tiles of the same size.
PLANNING THE LAYOUTFirst, determine how you will install the tiles. Cork tiles can be laid staggered ("half-brick") or in line with each other (“in bond”). Once you have selected the layout, you must determine the starting point. Generally, installation starts in the middle of the wall and progresses towards the sides. The wall should be measured up and divided to determine the middle of the wall, drawing vertical and horizontal guide lines.
The recommended adhesive for installing cork tiles is contact adhesive; this means that the adhesive has to be applied on both the support and the tiles. Stir the adhesive well before use. Follow the instructions on the adhesive packaging labels, as well as the information from technical data sheets. Apply a uniform adhesive layer on the back of all the cork tiles using a low nap roller. Make sure that the applied amount is sufficient to form a complete film of adhesive (around 100-120 g/m2 ). The adhesive on the back of tiles needs to dry completely. As the adhesive is a waterbased dispersion (most of it is water), it is very important that all the water dries off and that the cork tile is totally dry. When the adhesive is dry the coated surfaces are tacky to the touch and must show a closed, evenly glossy clear film. Pre-coated tiles may be stacked after drying and stored up to one day. Cork tiles can be pre-coated with the contact adhesive before the day they are laid (up to 24 hours in advance). On the day they are laid, the adhesive only needs to be applied to the wall and, following a sufficient drying time of 30-120 minutes (depending on the temperature, relative humidity and the absorption of the wall), the pre-coated cork tiles can be fixed in place using the contact method. You should limit yourself to an area that can be covered in two hours. Clean the used equipment with warm water.

Place the first tile carefully in the middle of the wall along the starting guide line, pressing it against the wall. Once the first cork tile is in place, align the next tile to the edges of the first and the guide line. Special attention should be paid to the alignment of each tile, making sure that the edges of each tile are pressed against each other. When the first row is properly aligned then the tiles must be hit with the rubber hammer for positive contact between the wall and tile, particularly around the edges and corners.
It must be taken into account that expansion and contraction of the cork tiles may occur. This is a consequence of changes in interior temperature and relative humidity as well as in the structure’s moisture content. A relative humidity between 40 % and 60 % is considered the ideal room condition, not just for your health and wellbeing, but also for your cork wall covering. When the rooms are heated during winter months, humidity is often below this range and this may lead to shrinkage of cork and the appearing of minor gaps.
