Glossary

80X80 is considered a large format tile

Primer

Fluid material applied in a thin layer. It serves to make the bearing surface suitable for laying and insulates the adhesive from direct contact with the surface, reducing the absorption of the bearing surface and strengthening the laying surface.

Diagonal laid

Layout design with the sides of the tile inclined by 45% in relation to the reference axis of the surface.

Laying with single buttering

Application of the adhesive on the laying surface only. Generally applied with a smooth trowel in order to obtain a uniform layer then spread with a notched trowel. The tiles are laid before the surface of the adhesive dries out and forms a film.

Laying with double-buttering

Application of adhesive on both the laying surface and the back of the tiles, in order to ensure that the adhesive layer is compact (full-bed). When combined, adhesive layers should not exceed the recommended maximum thickness. The tiles are laid before the surface of the adhesive dries out and forms a film.

Grouting

Operation that involves filling the joints, as well as filling the applied joints.

Parallel laid

Layout design with one side parallel to the reference axis of the surface.

Adhesive laid

Floor tiling installed by creating a state of adhesion between the mortar and the bearing surface, if necessary by means of a suitable adhesion promoter.

Mortar laid

Cement-based mortar laying, which involves applying a thin layer of "topping" or grout (a mixture of water and cement) before the tiles are laid.

Lapping tile

Ceramic tile, usually unglazed, which undergoes a mechanical surface treatment that involves the controlled removal of the most superficial layer, creating a polished-effect on the surface.

Structural joint

It must be placed in correspondence with joints present in the structure and must involve the entire combined thickness of the ceramic tile and the bearing surface.

Fraction joint

The thickness of the ceramic tile and part of the thickness of the bearing surface is of concern. It divides external tiling into smaller, approximately square-shaped fields.
