A work made to perfection guarantees durability, stength and aesthetic results.
La Pietra Compattata products must be installed on a concrete screed (with the addition of electro-welded wire mesh or suitable rebar) which is stable, dry and cured, neither frozen nor excessively hot, clean and free from any irregularities or substances that might jeopardize subsequent bonding.Expansion joints must be provided every 3/4 linear metres approximately and in any case at points identified by the architect or site manager. Always check that levels and slopes guarantee proper water runoff. La Pietra Compattata products are designed for cutting with a diamond blade wet saw. The material should be laid with 5 mm joints.
In any case, follow the instructions given by the architect or site manager.
To slow down the speed of absorption, wet the La Pietra Compattata material, without leaving water in the joints. Next, spread the sealant suitable for wide joints (coarse-grained), taking care to fill all the joints, spreading it with a rubber spatula (or rake) in all 4 directions. After a few minutes, emulsify with a traditional sponge or suitable floor buffer with brush. Next clean the floor, removing excess grout with a manual sponge or power sponge machine, taking care to change the water frequently.Follow the instructions given by the manufacturers of the materials for substrates and adhesives used.
