1. Exterior Stone Cladding -  Fitting Instruction 

• Before starting work, measure the room(s) carefully, calculate the area of the target surfaces and buy 10% more material than is theoretically required, with a sufficient supply of the primer, adhesive, pointing compound and impregnant - surface sealant. 
• If you need to install corners, purchase 5% more material than you have calculated. If you buy all the material you need at once, you can be sure the tile and joint color will be consistent.
• The variation of colors within a single box is intentional as it adds a natural look to the façade. Take tiles from a few boxes one by one to distribute tile tints evenly.
• Ambient temperature during, and within 48 hours after, the application should stay within the +5oC to +25oC range.
• Some information may not apply to certain product types.  Please read the instruction located on the product packaging before proceeding with work.

 Wall - Surface Preparation 

• All the surfaces should be correctly conditioned. They should be strong enough, uniformly textured, even, dry and free from any loose material, residues of paints, antiadhesive agents and grease.
• It is recommended to prime the target surface to improve bonding. 

BONDING

• Start lying the tiles from corners or most prominent places, avoiding forced joints on surfaces that you want to look perfect.
• The tile surface to be bonded has to be cleaned of efflorescence created by the manufacturing process with a spatula, wire brush, scrubbing brush, or similar tool.
• It is best to start from the bottom, resting the first row of tiles on the surface. If there is no even and horizontal support for tiles, mount a reference leveling screed on the wall using a mason’s level and a rule on a height not exceeding the height of a single row of tiles above the floor or ground.
• It is best to offset one row of tiles vs. the rows beneath and above (to avoid aligning the tiles/joints vertically). Please make sure each layer offset is approx 30% or 60% of the single tile lenght. 

• Apply the  adhesive by following the instruction provided on the adhesive used. 
• You can cut tiles with a diamond disk or a stone-cutting disk.

SURFACE PROOFING

•  Once done, impregnate the tiles with the Surface Sealant for easier tile cleaning in the future. It is best to impregnate the tiles after 14 days from the bonding.
