OUTDOOR FROST PROTECTION PRODUCTS
It must be ensured that the product is frost resistant. Tiles belonging to group BI, (porcelain tiles) are recommended. In any case consult the technical characteristics in our catalogue.
Prior to laying the product, the wall or floor must be perfectly levelled, either with levelling paste or mortar, forming the necessary slopes (2%) to prevent water stagnation.
In terraces or uncovered areas, waterproofing and drainage connected to a drain under the floor screed is recommended.
A special adhesive cement for exteriors must be used and always place the pieces with a joint of more than 5 mm, always use special grout for exteriors, covering the joint and prevent water from filtering through the joint.
Expansion joints must be made all around the perimeter, every 6-9 m2 and respect the structural expansion joints.
Always use a notched trowel in the application of the cement adhesive, the tiles should be hammered with a rubber hammer. No voids should be left under the surface of the piece, that is to say, it must be totally solidified.
It is recommended to use always a levelling system. Do not wet the pieces before its placement. Rectified products have to be installed always dry in order to avoid possible deformations of the material.
Prior to laying the rectified product, the wall must be plumbed with mortar. The minimum setting time of this surface should be 2-3 days.
Once the mortar is completely dry, the trowel should be used to apply the tile adhesive. The instructions indicated by the manufacturer on the product packaging must be strictly followed.
For a correct placement it is recommended a minimum joint between pieces of 2 mm.
The fixing, placement and seating of the pieces should never be done by hitting the material.
The walls must be completed.
Protect the pavements from premature traffic during the hardening phase.
Once all the pieces are in place and the tile adhesive has dried, proceed to grouting with grout and a rubber trowel. It is necessary to follow the instructions of kneading and placement indicated by the manufacturer on the product package.
Once the material has been grouted, it should be cleaned with a damp sponge, before the definitive hardening of the grouting.
