Surface Preparation:
The condition of the surface and the preparation of the surface are fundamental for the correct installation of stones ands. The supporting surfaces or foundations must be absolutely dry (residual humidity maximum 2.5%), level and free of dust, grease, wax, paint, dismantling agents and anything else which could prevent adhesion. Any pre-existing foundations must be solid, free of cracks, well attached to the base, resistant to the loads foreseen and complete with adequate structural joints.
Installation:
Butt joints are to be avoided. Proper laying and the correct alignment of thes require the use of open and uniform grout lines. The width of the grout line depends on the size of the tile with minimum 2-5mm width. The thermal conditions of the site must also be considered. Pre-existing and expansion joints, as well as the placement of joints must be respected by inserting silicone mastic along these joints. Interior expansion and control joints shall be installed in all directions at intervals of 16-18’.Under no circumstances shall control joints be cut in after the tiles have beeninstalled. If required, cut the tile and resume setting from the opposite side of the joint. Before continuing, rake the joint clean.
Recommended Adhesives:
The use of traditional sand and cement for the laying of our tiles ands is to be avoided. We recommend adhesives, which are specific for the general bonding of engineered stone materials. We recommend the use of a serrated trowel to apply the adhesive, so that the quantity extended onto the foundation ensures coverage of 100% of the. We also recommend back buttering each tile.
For quartz-engineered stone we recommend the use of two-component pre-packeds (synthetic latex with special cement powders and siliceous sands of a fast setting nature)
For areas subjected to direct sunlight exposure, we recommend the use of epoxy based adhesives.
