Foundation in concrete
The foundation in concrete is obtained by mixing sand, fine gravel, water and cement in measure of 2 quintals for cubic meter, laid for 10/15 cm on the foundation, by drowning in the foundation an electro-welded net of mm 6 x 20/20.
A) ADHESIVE/MORTAL LAYER
Already during the planning provide for suitable expansion joints according to the size and geometric shape of the floor. The joints have to cut the foundation, the cement floor and the paving, in order to have the possibility to “absorb” eventual expansions.
Realize the paving by paying attention to arrange an appropriate slope of 1cm per meter in order to guarantee a good water down flow and avoid (especially in cold areas) that the paving remains “in immersion”.
Proceed with the assembling of the tiles with a specific adhesive for exteriors, by following the specific instructions of the used adhesive.
For mountain areas we advise the laying with cement joint in order to guarantee a better seal.
Carry out the joint of the tiles by being careful to fill it up till the chamfer (as you can see also on the scheme), in order to correct possible light unevennesses of the tiles‘ chamfer.
We advise to realize a cement joint, in order to seal the interstices between one tile and the other and for preventing that water stagnates between the cement layer and the tiles, in order to avoid separations in case of freeze and to contrast the efflorescence phenomenon.
In case they are laid with a joint, we advise a width of the joint of approx. 8 mm.
Sealing can be done with normal grout or with other preparations available on the market.
It is advisable to wet the tiles thoroughly before grooving and clean them immediately afterwards with a moist sponge, by paying attention to rinse it often.
When the paving has been finished, carry out a cleaning of the yard.
In case of obstinate dirt use MaspeClean as detergent.
In particular cases we suggest the use of a monobrush polishing machine to lay the MaspeClean and to remove mechanically the dirt.
Otherwise scratch the paving by using a manual brush.
