In all cases, regardless of the type of substrate, it is very important to ensure that the surface is level, to prevent the formation of vacuums under the tiles that could weaken the laying, with particular attention to raised sections and the presence of foreign rigid bodies. Lay the tiles by following the indications of the designer, site manager and the laying specifications. Porcelain stoneware must be laid so that the adhesive ensures the perfect filling and adhesion over time, to prevent any deformation and guarantee the utmost reliability in all laying conditions. Select the most suitable adhesive by following the indications of the adhesive manufacturer. As a rule we recommend adhesives that ensure a good type C2 wettability (improved cementitious adhesive). The tiles can be laid, in the most common situations, with joints of minimum 2-3 mm, even if in certain situations (large surfaces, facings, deformable supports, etc.) larger joints are required along with expansion and distribution joints. We decline all responsibility linked to laying tiles without joints.
We recommend the use of a spatula with rounded teeth to guarantee a sufficient quantity of glue on the substrate and ensure that the tiles are soaked 100%. Use the double spreading technique to ensure that there are no gaps on the back of the tile or use an adhesive that ensures a perfect filling. During the laying make sure that the tiles follow the expansion joints on the substrate and the walls. Create division joints of about 1 cm for very large surfaces, dividing the area as follows: -on substrates subject to movements or bending allow for sections of about 9-12 m²; -on stable surfaces the joints can be about every 16 – 25 m². Lay tiles at about 5 mm from walls, columns, edges, corners, etc. During laying do not subject ceramic tiles to excessive stresses or violent knocks. The tiles can be cut without particular issues and after laying we recommend waiting for the adhesive to harden before making holes or cuts for accessories.
