🕑 Reading time: 1 minute. The natural stone cladding can be installed mainly by two methods, namely the wet installation method and dry installation method. Both the ways have their pros and cons, whose application is based on the objective and the wall conditions. The article explains both the methods along with their pros and cons.
Wet Installation of Natural Stone Cladding. Dry Method of Natural Stone Installation. The wet installation is the most commonly used method for natural stone cladding. The crucial decision is to select the best method from the variety of installation options given by the wet process.
The wet method can be performed by the Direct Adhesion Method and Spot Bonding Method.
Direct adhesion method is the most common wet met method employed. A wet method, by default, is considered a direct adhesion method. It makes use of a liquid latex combined with a cement-based filler powder to form cement mortar.
The mortar is applied to the surface in thin layers. The method does not demand onsite drilling. It is the cheapest method, among other installation methods. Spot bonding makes use of adhesives to bond the stone cladding onto the wall surface.
The difference between spot bonding and direct adhesion method is, the adhesive uses only 10 % of the area. This installation technique hence leaves gaps or air pockets between the stone and the wall.
The gaps and air pockets created thus reduce the chances of water staining. The main advantages of wet installation of cladding are:.
The method is cheap.
The technique does not require on-site drilling.
No on-site drilling prevents cracks on the walls.
Bond between the stone and cladding is entirely made throughout the area.
No space is left between them. More even look is achieved.
The later expansion is not possible due to the edge to edge bonding.
This limitation results in the buckling of the natural stone.
Hence, this method requires adequate expansion and contraction joints.
Improper bond between the wall and the adhesive or the mortar can make the stone to fall off.
The cladding stone may absorb water from the mortar.
This makes the stone to change its color.
The wet method, though, is easy, can consume a lot of time.
In this method, fixed or embedded anchors, metal framing, steel brackets, or ties attach the stone to the surface.
The method is applied only on thicker and stronger stone cladding, as the process requires drilling of a hole into the stone.
This method demands a gap of ¾ inch to allow drainage. Dry stone mechanical method is the best and safest way compared to wet cladding installation.
