How To Set Stone In Concrete
Rock Veneer Installation
The following guideline is a full 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 be unique and may crave additional steps. Please contact an RCP Cake & Brick to discuss your particular project. View all available Stone Veneer styles.
Things to Go along In Mind
- Go along your hands and your stone veneer clean during the installation process
- It is important not to allow mortar to dry out on the face up of the stone. Moisture mortar on stone will leave a filmy remainder that dulls the advent of the rock and should be removed immediately before it dries/hardens. Removal can be accomplished using a stiff castor and make clean h2o
- Place a protective material on the footing where pelting or water tin cause mud to splash onto your rock
- All stone should exist applied according to local building codes
- H2o infiltration and damage can be acquired from incorrect installation. Stone should be installed at to the lowest degree three" above form level to prevent water from continually saturating behind the dorsum of the stone and causing structural impairment
Step 1: Calculating Materials
Before you tin begin the installation project, you volition need to calculate the proper amount of material for your thin stone veneer project.
How Much Rock Do You Need?
Begin past figuring the square footage of the area you lot program to embrace with rock (length x height). If your project includes corner stones, deduct 1 square foot for each linear foot of corners that you volition use. Not Sure? Call RCP Block & Brick and we tin can aid summate your stone needs.
Consider Mortar Articulation Size:
One aspect to consider when calculating your materials is the size of the mortar joint betwixt the pieces of stone. Near stone is packaged assuming a 1/ii" mortar joint. If your joint will vary (such as a dry-stack or over grout application) adjust your estimates appropriately.

Stride 2: Surface Preparation
Preparation of the surface is a cardinal attribute in preventing whatsoever water damage and making sure your stone veneer project remains structurally sound for the life of the installation.
Framed Outside Wall:
Including Plywood Paneling, Wall Sheathing, or Flush Metal Siding
Cover surface with a weather condition resistant barrier such equally tar paper. Be sure to overlap joints 4" in shingle style. In accordance with local building codes, install metallic board on acme of the weather resistant barrier using galvanized nails or screws 6" on centre vertically and 16" on center horizontally, penetrating the studs a minimum of 1". Stop the metal board 1" from finished edges. Exist certain to wrap all corners overlapping the metal lath at lease 4".
Framed Interior Wall:
Including Plywood, Sheetrock, Green Sheetrock, or Cobweb Cement Lath
In In accordance with local building codes, install metal lath using galvanized nails or screws 6" on center vertically and xvi" on center horizontally, penetrating the studs a minimum of 1". Stop the metal board 1" from finished edges. Be certain to wrap all corners overlapping the metal lath at lease iv". (It is not necessary to use expanded metal lath on fiber cement board unless required by local building codes)
Physical Exterior or Interior Wall
Including Cleaned and Untreated Concrete, Masonry, or Stucco
Stone veneer can be installed directly to these surfaces if clean and absent-minded of whatsoever paint or debris. Be sure to audit new concrete to insure at that place is no release agents (form oil) on the surface. If release agents are present, compose the surface of the concrete with etching agent. Surfaces that have been painted must exist sand blasted or otherwise stripped of paint. Surface must exist free of paint, dust, or dirt. If cleaning of surface is too difficult, metal board may be affixed to the surface with concrete nails. In accordance with local building codes, install metal board using galvanized nails or screws 6" on center vertically and 16" on center horizontally, penetrating the studs a minimum of 1". Stop metal lath one" from finished edges. Be certain to wrap all corners, overlapping the metal lath at least 4"

Step 3: Scratch Coat
A scratch coat volition exist needed when metal board is used. This step is not necessary when applying stone veneer to a cleaned concrete, masonry, or stucco surface.
Mixing the Scratch Coat:
i role Blazon S Masonry Cement to 2.v parts sand. Dry mix the sand and cement together and avoid creating clumps in the mixture. Add water slowly to the mixture a trivial at a time, continually mixing until y'all take accomplished the consistency of a paste or whipped potatoes. Mix a minimum of five minutes.
Applying the Scratch Glaze:
If a scratch coat is necessary, use a masonry trowel to employ a 1/ii" to 3/4" layer of the scratch coat mix over your metal board. Cover the entire area of the lath, working the cement into the holes and scraping off whatever excess. Use a notched trowel to lightly rake horizontal grooves in the scratch coat while the cement is notwithstanding slightly moisture and allow to dry for 24 hours.

Step 4: Preparing Your Rock for Installation
To accomplish the all-time results, there are a few things you should accept intendance of before starting your stone veneer installation.
Plan Your Layout:
Before applying the stone, information technology is a skilful idea to lay the rock out flat to determine the sizing and colors of each individual piece, how they volition be laid out for your project, and if any trimming is necessary. Attempt to proceed joints a consequent height and width. Normally vertical and horizontal joints should exist staggered to forestall long, unbroken lines that may draw the eye to a particular area.
Trimming the Rock:
If cut the stone is necessary, a Skill saw with either a dry or wet cutting diamond or masonry blade will work. You lot may besides want to utilise a masonry hammer to break the stone, giving it a more than natural appearance. A nipper can likewise be used to trim small amounts off the stone.
Make clean the Stone:
Be certain that the surface of the stone is free of dust, clay, or any loose particles. If necessary, wash the stone completely and allow to dry out.

Footstep 5: Installing the Rock Veneer
Y'all will be affixing the stone veneer to the scratch coat using a stone veneer mortar. Below are the steps involved.
Mixing the Mortar:
Use a pre-composite, polymer fortified Blazon S mortar and water known equally SVM (Stone Veneer Mortar). Call an RCP Cake & Brick near you for bachelor products and tips. Mix according to manufacturer's directions.
Installing the Stone:
It is recommended to install all corner pieces first earlier installing the field. It is also recommended to work your way from the bottom to top.
Use a masonry castor or sponge to dampen the back of the stone, but do not saturate it. This prevents the stone from pulling wet away from the mortar allowing it to dry naturally and with a stronger bail.
To lay the rock, use a masonry trowel to butter the back of the rock with i/2" to 1" layer of mortar. Using your trowel, create a ridge effectually the exterior back of the stone. This will create suction when putting the stone in identify, which will help to hold the rock until the mortar sets up. Lay the rock against the wall, pressing and rotating slightly, forcing some of the mortar to squeeze out freely.

Stride 6: Grouting and Tooling
In one case the stone has been affixed to the scratch coat using mortar, the joints, or gaps between the rock, will exist filled with grout.
Filling the Joints:
Use Pre-blended Blazon S mortar. Using a grout handbag, cutting a pigsty approximately 1/2" in the tip of the bag (if pigsty is non already provided). Fill up your grout purse about one-half total with your grout mixture. Twist the top end of the pocketbook and squirt a small amount into a bucket to forestall air pockets. Make full all the joints between the stones with about a ane/2" layer of mortar (more or less depending on the desired upshot and joint size.)
Tooling the Joints:
As the grout stiffens, tool to the desired depth using a joint tool. Brush the joints with a whisk broom to smooth them out and make clean abroad any loose mortar. Grout is gear up for finishing when it crumbles abroad similar sand when brushed. If the grout smears or falls away in large chunks, information technology is all the same too moisture for brushing or hitting. Finally use a soft bristled brush to sweep the grit off the stone.
