How To Install Stone Veneer On Concrete Wall
Stone Veneer Installation
The following guideline is a general overview of the proper steps involved when installing natural or manufactured thin stone veneer, in the traditional method, where no special circumstances are present. Your specific project may exist unique and may require additional steps. Delight contact an RCP Cake & Brick to hash out your item project. View all available Stone Veneer styles.
Things to Continue In Mind
- Keep your hands and your stone veneer clean during the installation procedure
- It is of import not to allow mortar to dry out on the face of the stone. Wet mortar on stone volition leave a filmy residue that dulls the advent of the stone and should be removed immediately before it dries/hardens. Removal can be accomplished using a stiff brush and clean h2o
- Place a protective material on the basis where rain or water tin crusade mud to splash onto your stone
- All stone should exist practical according to local building codes
- Water infiltration and damage can be acquired from wrong installation. Rock should be installed at least 3" higher up grade level to preclude water from continually saturating behind the back of the rock and causing structural harm
Step 1: Calculating Materials
Before you can begin the installation project, you will need to calculate the proper corporeality of material for your thin stone veneer projection.
How Much Rock Practise Yous Need?
Begin by figuring the square footage of the surface area you program to cover with rock (length x peak). If your projection includes corner stones, deduct one square foot for each linear foot of corners that you will utilize. Non Sure? Call RCP Cake & Brick and we can help calculate your stone needs.
Consider Mortar Joint Size:
Ane attribute to consider when calculating your materials is the size of the mortar joint betwixt the pieces of stone. Most stone is packaged bold a 1/2" mortar joint. If your joint will vary (such every bit a dry out-stack or over grout application) adjust your estimates accordingly.

Step 2: Surface Preparation
Preparation of the surface is a fundamental aspect in preventing whatsoever water impairment and making certain your stone veneer project remains structurally sound for the life of the installation.
Framed Exterior Wall:
Including Plywood Paneling, Wall Sheathing, or Flush Metal Siding
Encompass surface with a weather resistant barrier such every bit tar paper. Be certain to overlap joints 4" in shingle style. In accordance with local edifice codes, install metal lath on top of the atmospheric condition resistant barrier using galvanized nails or screws half-dozen" on centre vertically and xvi" on centre horizontally, penetrating the studs a minimum of i". Stop the metallic lath i" from finished edges. Be sure to wrap all corners overlapping the metallic lath at lease 4".
Framed Interior Wall:
Including Plywood, Sheetrock, Green Sheetrock, or Fiber Cement Board
In In accordance with local building codes, install metallic lath using galvanized nails or screws 6" on centre vertically and 16" on center horizontally, penetrating the studs a minimum of 1". Stop the metal lath ane" from finished edges. Be sure to wrap all corners overlapping the metal board at lease 4". (It is not necessary to use expanded metal lath on fiber cement board unless required by local building codes)
Concrete Exterior or Interior Wall
Including Cleaned and Untreated Concrete, Masonry, or Stucco
Stone veneer tin can exist installed directly to these surfaces if clean and absent of whatsoever paint or droppings. Be sure to inspect new concrete to insure there is no release agents (form oil) on the surface. If release agents are present, etch the surface of the physical with etching agent. Surfaces that have been painted must be sand blasted or otherwise stripped of paint. Surface must be complimentary of paint, dust, or dirt. If cleaning of surface is too difficult, metal lath may exist affixed to the surface with physical nails. In accordance with local building codes, install metallic lath using galvanized nails or screws 6" on heart vertically and 16" on middle horizontally, penetrating the studs a minimum of 1". Cease metallic lath one" from finished edges. Be certain to wrap all corners, overlapping the metal board at least 4"

Step 3: Scratch Coat
A scratch coat will exist needed when metal board is used. This step is not necessary when applying stone veneer to a cleaned physical, masonry, or stucco surface.
Mixing the Scratch Coat:
1 part Type Due south Masonry Cement to 2.5 parts sand. Dry mix the sand and cement together and avoid creating clumps in the mixture. Add water slowly to the mixture a piddling at a fourth dimension, continually mixing until you have achieved the consistency of a paste or whipped potatoes. Mix a minimum of 5 minutes.
Applying the Scratch Coat:
If a scratch coat is necessary, use a masonry trowel to apply a i/2" to three/4" layer of the scratch coat mix over your metal board. Cover the unabridged area of the lath, working the cement into the holes and scraping off any excess. Use a notched trowel to lightly rake horizontal grooves in the scratch coat while the cement is all the same slightly wet and allow to dry for 24 hours.

Stride iv: Preparing Your Stone for Installation
To achieve the all-time results, at that place are a few things you lot should take intendance of before starting your rock veneer installation.
Plan Your Layout:
Earlier applying the rock, it is a good idea to lay the stone out apartment to determine the sizing and colors of each private slice, how they will be laid out for your project, and if any trimming is necessary. Attempt to keep joints a consequent pinnacle and width. Normally vertical and horizontal joints should exist staggered to forbid long, unbroken lines that may draw the eye to a particular area.
Trimming the Stone:
If cut the stone is necessary, a Skill saw with either a dry or wet cut diamond or masonry blade will work. You may as well desire to utilize a masonry hammer to pause the rock, giving it a more natural appearance. A nipper can besides be used to trim pocket-size amounts off the stone.
Clean the Stone:
Be sure that the surface of the stone is free of grit, clay, or any loose particles. If necessary, wash the stone completely and allow to dry out.
Programme Your Layout Before Installing
Step 5: Installing the Rock Veneer
You will be affixing the rock veneer to the scratch glaze using a stone veneer mortar. Below are the steps involved.
Mixing the Mortar:
Use a pre-blended, polymer fortified Type S mortar and water known every bit SVM (Rock Veneer Mortar). Call an RCP Block & Brick near you lot for available products and tips. Mix co-ordinate to manufacturer's directions.
Installing the Stone:
It is recommended to install all corner pieces first before installing the field. Information technology is also recommended to piece of work your way from the bottom to top.
Use a masonry brush or sponge to dampen the back of the stone, but do not saturate it. This prevents the stone from pulling wet abroad from the mortar allowing it to dry naturally and with a stronger bond.
To lay the stone, use a masonry trowel to butter the dorsum of the stone with 1/ii" to 1" layer of mortar. Using your trowel, create a ridge around the exterior back of the rock. This volition create suction when putting the stone in place, which volition aid to hold the stone until the mortar sets up. Lay the rock confronting the wall, pressing and rotating slightly, forcing some of the mortar to squeeze out freely.

Stride 6: Grouting and Tooling
Once the rock has been affixed to the scratch coat using mortar, the joints, or gaps between the stone, will be filled with grout.
Filling the Joints:
Use Pre-blended Type S mortar. Using a grout handbag, cut a pigsty approximately 1/2" in the tip of the bag (if hole is not already provided). Make full your grout bag about half total with your grout mixture. Twist the top stop of the handbag and eject a small amount into a bucket to prevent air pockets. Fill all the joints between the stones with about a one/2" layer of mortar (more or less depending on the desired effect and joint size.)
Tooling the Joints:
Every bit the grout stiffens, tool to the desired depth using a joint tool. Castor the joints with a whisk broom to smooth them out and clean away whatsoever loose mortar. Grout is ready for finishing when information technology crumbles away like sand when brushed. If the grout smears or falls away in large chunks, it is nevertheless also wet for brushing or striking. Finally use a soft bristled castor to sweep the grit off the stone.
