Installation Instructions – Step by Step Guide

We clean the substrate from dust and dirt, for good accretion of the mortar-shapes, thickness and textures. Level out the first line of where the stones will be placed.

If we work on a absorbent substrate like gypsum board or wood, we have to apply primer to reduce the absorbency.

Prepare mortar taking into consideration the amount of water for good accretion and the right consistency.

Apply mortar on the installaton surface as much as needed so that it does not dry out when installing the stone.

Lay out stones and mix from various cartons at least 2m² to create a ballance between different colors, shapes, thickness and textures.

If the installation includes corners then begin from the corner of the wall & continue the installation in line with the flat elements.

If empty gaps are large, fill them with stones by cutting them to the size needed.
If empty gaps are large, fill them with stones by cutting them to the size needed.
Apply mortar at the back surface of the Stone as much as possible so there is no gap between the stone and the surface.
Place the stone by pressing hard to ensure a very good adherence of the mortar in the back surface of the stone.
In the installation of stone use a rubber mallet (rubber hammer) in order not to wound the stone.

Stone application without joints

Fill the perimetric channel of the stone with mortar by using the spatula. Remove any excess mortar using a towel.

Stone application with joints

Provided that there is a joint, in order to stabilize the stones small spacers can be used where it is needed.
For the installation use a pastry bag or a grouting gun. In both cases effectively cut the end until the desirable width for the joint is achieved.
Lay the mortar with a spatula or special tool.
