• It is of primary importance that you have a perfectly healthy support. On painted supports, carry out a scouring with the grinding machine or a sanding (for smooth surfaces).
• If the support is very smooth, carry out a pricking, then apply Sika Top 121 liquid with the brush.
• Use an adhesive meeting standards NFP 18-840 and NFP 15-451 containing resin and cement. Take advice from us to know about available products .

• Once the support has been washed , draw level lines, then apply glue on all the stone surface.
• It is of primary importance to carry out a gluing of both stone and support.

• Stick the stone by a light pressure and use a rubber hammer.
• Put 1 to 1,5 cm blocks between each stone.

• Once the glue is dry, joint with gray mortar (sand and cement) or beige mortar (wall coating).
• Fill the joint with a joint-trowel .
• In order to soften the joint, you can add a latex stopper in your mixture.

Two methods are possible:

• 1st method:
  Finish the joint with a wet brush in order to smooth it. Clean up the burs with a mason-sponge.
  
  
• 2nd method:
  Make a joint with the stencil key set: Equalize the joint using a joints-trowel . Finish with the metal brush.

• After 24 H, wash with chlorydric-acid mixed with water (1 L of acid for 4 L of water).
• Let take effect for 30 seconds, then rinse with water.
• Pass a water-repellent product to preserve the state of the stone.

• If the lower part of the lintel is to be equipped, you will have to to descend it of 0,5 cm in order to cover it with plates.
• If the angle-return is envisaged, (plates 25 cm X 30 cm) make the stones exceed of 0,5 cm from frontage wall.
• It is advised to carry out a pegging of the lintels and of large stones with ankles to be struck (diam 8mm), then to cover the screw heads with with coating.
• If the set is expected only on frontage (without returns), apply the stone in the alignment of the door window or lintel table.

• Mark a draw on the back of the stone.
• Carry out the cut with a grinding machine equipped with a diamond- edged disc diam. 125.
• Then burst the edge cut using a hammer. Pass pure chlorydric acid on the cut.
• Rinse with water 30 seconds afterwards.
