Preparation for Laying:

The VALPIETRA® panels can be laid directly on bare walls, plastered and/or painted surfaces and on any support in the form of chipboard, adhering to the following warnings:

In general:

• the laying surface must be compact and free of dust and dirt. Any traces of greases, waxes, oils, enamels, varnishes, etc., must be removed;
• concrete bases must be dry to avoid loss of adhesion;
• any rising damp should be dealt with and solved before laying;
• for installation on walls more than 3 meters in height a wire mesh must be used as a support;
• a double layer of glue is needed (one the wall and one on the panel) applied with a toothed spatula.

In particular:

• bare walls: if the surface of the walls are not flush and compact then they have to be smoothed
• plastered and/or painted surfaces: provide a stitching of the laying surface (in the case of not using the AV9 glue, a primer must be used)
• supports in chipboard, MDF or plasterboard must be anchored to the underlying wall, to support the total weight of the panels (in the case of not using the glue AV9, you must use a primer.

Operating Limits:

• do not use in areas that are completely immersed in water;
• do not lay by direct heat  or in contact with metal components that reach high temperatures;
• maintain a distance of at least 30 cm in the case of laying on walls behind pellet wood burners;
• don’t lay on walls behind directly on the heat source;
