etc.) are suitable for the intended use and have been correctly stored. Expansion joints Check that the perimeter, expansion, divider and structural elastic joints have been correctly designed and prepared. Divider joints are normally needed for 20/25 m2 (21.9/27.3yd2) indoor sections, and 9-15m2 (9.84/16.4yd2) outdoor sections. For exteriors, make sure joints are properly waterproofed and sealed. Back-buttering For exterior installations, large tiles, floors with intense or heavy traffic, vibrating supports and situations exposed to high temperature fluctuations, the adhesive mortar must be...

In the case of mosaics mounted on adhesive paper or film, this must be removed at least 24 hours after installation once the adhesive has sufficiently set, to prevent the detachment of the tiles. The tiled surface must be protected for at least 24 hours against any rain wash, and for approximately 5-7 days against any frost and direct sunlight. Tiled surfaces are ready for use after about 24 hours. Marble, natural and recomposed stones Materials subject to deformation or stains due to water absorption require a quick-setting (C2F) or reactive (R2) adhesive. Marble and natural stones, even if...
