An economical way to create a natural stone look on both exterior and interior wall is by the use of stone cladding. These are a light weight cladding system designed to apply a stone veneer cut from natural stone. Different suppliers and manufactures will have a range of designs and products.
Differing with products provided by individual suppliers installation of stone cladding to smaller projects can be a DIY solution.
A rough idea of requirements we have provided a simple, basic guide. Full installation guides, including correct sub strata, preparation, adhesives and grouts should be supplier by individual stone suppliers, may provide video instruction as well as contacts for professional installers. A poorly installed rendered wall will detract from the look and value of your property.
Applied to clean flat substrata (often fibre cement sheet) covered with an adhesive fibre glass mesh for adhesion and stability joints are sealed and a render coat is then applied. The render coat is allowed to dry and a flexible adhesive is applied. Adhesive is available as a pre mixed product as well as in powdered form.
Stone cladding is then applied, stone should ready to attaching so consider laying out the pattern on the ground if a complicated project is to be considered, this allows for pre cutting using a masonry saw.
Stone is applied using mixed adhesive, corners first starting at the bottom and checking each row for levels as you go. Use wedges to maintain a constant grouting gap.
Any extra or overflow adhesive grout should be removed with a trowel and damp cloth as you go. Air gaps behind the stone should be eliminated and remember to check those levels every second row. Removable spacers or wedges can be used to adjust levels as you go, so have plenty of these ready before you start
Grout is mixed and applied using a grouting bag, similar to a large ‘cake icing bag.
It is essential to consider the actual application before deciding on the fixing system , adhesive fixing systems as described above are generally only suitable for single story use. Many technical aspects need to need considered for example any expansion joints need to be left uncovered. Professional installers can advise on the best method of installing stone cladding for your application
Mechanical fixing, may be required for taller structures. Different Stone Cladding systems will require different fixing systems and local council building regulations will need to followed.
