Installation of wall plates

If covering a wall with marble or comblanchien plates is an expensive and difficult operation for the amateur, the brick or reconstituted stone plates make it possible to easily create decorations thanks to simple elements to ask.

Specificity of the materials for cladding boards

The facing plates are made of reconstituted stone or brick, each generally reproducing an element, but there are also large plates having a composition of several elements.

Implementation of wall plates

Platelet cutting
Cutting platelets, and especially large plates composition, necessarily requires the use of a chainsaw equipped with a diamond disc:

  • wear safety glasses and gloves during the operation taking into account the risk of projection of shards;
  • secure the plate securely to cut, using a clamp.

The physical characteristics of the material impose certain limitations to their use, which can not be neglected, under penalty of seeing the platelets come off sooner or later:

  • laying in the bathroom these porous materials are not recommended unless they are treated after laying with a waterproofing product;
  • these pads can only be applied on a robust structure, because of their mass (25 to 35 kg / m²).

The laying of large plates is done by double sizing: on the wall and back of the plate.

Double sizing

Large wafers should be applied to the adhesive mortar, spread over both the surface to be covered and the back of each wafer.

Corner elements provide the effect of stone masonry.

Laying a corner plate

Corner elements simplify the realization of the siding and allow to easily obtain the appearance of a stone work.

The adhesive for laying pads
Although there are now self-adhesive pads, most arise as tiling, mortar-glue more suitable for a mass usually important to remember. This implementation has some peculiarities:

  • delivered in pre-dosed bagsthe mortar must be tempered in non-calcareous drinking water because the limestone will migrate into the porous material of the platelets to give unsightly blooms to the surface;
  • place the mortar on the wall with a trowelthen spread with a toothed spatula with large square teeth of 6 or 9 mm;
  • also put adhesive mortar on the back each wafer, in a layer of 3 to 5 mm depending on the thickness of the wafers;
  • do not fill with adhesive mortar an area of ​​more than 1.5 to 2 m² Everytime;
  • eliminate possible mortar reflux in the joints between plates, for example with the blade of a screwdriver.

Finishes for cladding boards

This type of platelet always arises with wide joints (from 6 to 12 mm), requiring a jointing product also specific. Gaskets made with a cement slip would crack quickly.

The grouting paste
The grouting paste, which can sometimes be tinted, is a rich formulation promoting the expulsion of liquids, very strong adhesion and devoid of shrinkage. It must be implemented with the tools most often provided in the installation kit:

  • a piping bagin which a quantity of pulp sufficient to fill 1 m to 1.5 m must be transferred;
  • a joint ironimmediately apply to the freshly applied product to equalize the thickness;
  • a bristle brush hard to pass over the surface of the joint to smooth it.

The siding protection is necessary when the coating is subjected to a high humidity, and in particular to the runoff: use a transparent water-repellent product, applied with the roller, after having protected neighboring frames of wood or aluminum.

Making joints between the pads

These small accessories make it possible to obtain a regular spacing on the whole surface.

Spacer blocks

These small "T" polystyrene, allow to achieve perfectly balanced joints.

A socket pocket makes it possible to make the joints between the pads without staining it.

Application of joint compound

1. The joints are filled with a specific grouting paste, by means of a piping bag.

The passage of a joint iron makes it possible to smooth the joints. A brush stroke completes the smoothing of the joint.

Finishing joints

2. To finish the joints, use a straightener, then finish with a brush with hard bristles.
