Stone Cladding - Australian Installation Guide

Mortar

The mortar is the most important factor in the application. Be sure all measures are consistent and mixed thoroughly. The mortar is used to affix Craft Stone to each of the three optional sub-strates listed below.

All substrates are to be primed. As Australia has a great variance in its sand content and type, the following is a guide suitable for sand in Victoria.

Primer

All surfaces are to be primed.

Mix 2 Parts STONEBOND (bonding agent) & 1 Part Water - bonding agent with cement, blend to a milky paste. Apply with brush or roller to the wall face. Best adhesion is reached when the stone is applied whilst the primer is moist.

Standard Mortar Mix:

• Use a 9 liter (laundry bucket) as one part.
• 2 parts washed sand, (sand is to be low in clay content).
• 1 part general purpose Portland cement.
• 2 Litres of STONEBOND (Bonding agent).
• Add Water to desired consistency.

Mortar is best when mixed wet similar to brickies "wet mix". Moisture is usually sucked out of the mix due to the dry cement block or render wall.

During hot conditions we recommend each stone to be dipped into a bucket of clean water, this aids in enabling the mortar to ooze out from the back of the stone to the face.

No voids are to be seen between each stone. Joints are to be fully loaded during installation to make grouting easier and prevent moisture penetrating through to the sub-structure. Flashings are to be installed to top of wall to prevent water penetration.
