Laying porcelain tiles requires the right materials and methodology. Expert tiling will enhance the beauty and guarantee a long lasting durability of a tiled surface, especially when the product is laid in a public area.
As a general rule, cement based tiles adhesives (C2), dispersion adhesives (D2), or reaction resins (R2) are used to secure porcelain tiles, especially in big areas, outdoor surfaces and coverings in general.
Follow the adhesive manufacturer’s instructions and check that the product is recommended as a bonding agent to be used with porcelain gres tiles. Traditional mortars are not recommended bonding agents.
Firstly, floor layers have to check the materials they are working with are the once indicated. No claims are accepted on laid floors! So make sure you check the material before and if in doubt of finish, colour ,… get in touch with your supplier.
Creative pattern designs need a preliminary laying plan. Just dry lay the tiles on the floor to see what they will look like when the job is done.
The surface must be flat, dry and clean before fixing the tiles. Use a 6mm notched trowel with 30x30 cm or smaller tiles and a 9 to 10mm notched trowel with larger tiles or when a double –coat adhesive is applied to both the surface and the back of the tile to improve bonding.
Make sure the tiles are flat and even before fixing them. Use a white rubber mallet to level them out, since a dark coloured one will leave stains that are difficult to remove and require special cleaning methods.
If you want to arrange rectangular tiles with a brickwork pattern place the tiles ¼ or 1/5 from the edge.
Remember that tiles can only be walked on when the adhesive has sealed. ALWAYS protect the tiles from damage by other improvement or construction work.
Only grout recommended for porcelain tiles should be used. They are different grouts for different laying methods, floor special use or purpose and the weather. Grout must be applied with a hard rubber grout float that forces the grout into the joint. Follow the grout manufacturer’s instructions. Wipe off the excess grout before it sets with a wet soft sponge and water, taking care not to damage the joint and following the manufacturer’s instructions. To remove any joint or cement residues use a cement remover as indicated by the manufacturer. Do not use white cement nor materials containing carbon black pigments.
