Applying Stone & Grouting |
Applying Tejas Textured Stone
1.
Surface Area
Use a notched float to apply mortar 1/2” to 3/4” thick.
2.
Joint Width
If mortared application is specified, joints should be 1/2” to get the most natural look.
3.
Setting Stones In Mortar
Cover the entire back of the stone with mortar and press the stone firmly into the mortar bed to ensure a good bond. Press hard enough to squeeze out a little mortar around all the edges of the stone. Make sure you have complete coverage between the mortar bed and the surface of the stone.
4.
Corner Pieces
Corner pieces should be installed first. Alternate the long and short legs on the corner pieces in opposite directions.
5.
Flat Pieces
After the corner pieces are installed apply flat pieces starting at the outside working in toward the wall center.
6.
Cutting and Trimming
Use the rear of the brick hammer, edge of trowel, nippers or a circular saw with an abrasive blade to cut and shape stones. If necessary, broken stones can be trimmed and shaped to fill in any gaps. For the most attractive finished appearance, coat with mortar any cut or broken edges. Also, try to place cut edges up when they are above eye level and down when they are below eye level.
7.
Level and Plumb Joint Lines
Joint lines should be level and plumb. For a more natural look, place long, rectangular pieces of stone horizontally.
8.
Weathered Edge, Stack Stone and Ledge Stone
In mortarless joint applications where no mortar joints are used, use a bonding agent and seal with a breathable (non-film-forming) sealer.
Grouting & Finishing Joints
1.
Grouting Joints
If more mortar is needed, fill in the joints with a mortar bag, taking care to avoid getting mortar on the stones’ surface. Any accidental smears can be removed with a whisk broom after the mortar is crumbly. Never use a wet brush or wire brush.
2.
Finishing Joints
Proper jointing gives your project an appealing and professional finish. Before finishing, allow mortar joints to become firm (approximately 30-60 minutes), then point them up with a metal jointing tool. Weather conditions and the type of surface both influence drying time. Remove excess mortar then firmly compress and seal the edges around the stones.
Additional Frequently Asked Installation Questions
1.
Can Tejas Textured Stone be cut?
Tejas Textured Stone can be cut with many masonry tools including a masonry saw, nippers, and/or a hatchet.
2.
Do any stones repeat themselves?
No, there are over 250 different stones in a style and each stone is hand painted. Each stone is handcrafted so no two stones are the same.
3.
Are control joints needed when using Tejas Textured Stone?
Please consult your architect or project engineer.
4.
What kind of support, if any, would I use when using Tejas Textured Stone?
One of the features of manufactured stone is its lightweight factor. Because it is a masonry veneer, it is able to be attached to a surface with mortar and does not require a structural support ledge.
5.
Can I use a weather resistant barrier on Tejas Textured Stone?
If you choose to use a weather resistant barrier, it needs to be equivalent to ASTM D226, Type 1 No. 15, Non-Perforated Asphalt Saturated Felt or UBC Standard 14-1, Kraft Waterproof Building Paper.
6.

How Much Stone Do You Need?
Just follow these easy steps to determine how much Tejas Textured Stone you will need.
1.
Measure the width and the height of the area to be covered and convert to square footage; width x height = total square footage.
2.
Figure the square feet of any windows, doors and openings and subtract this amount from the first figure. (total square footage – windows, doors and openings).
3.
Determine how many linear feet of corners you’ll need. Measure the linear footage of the outside corner pieces. One linear foot of corners will cover about 1/2 square foot of flat area – ie, 20 linear feet of corners = 10 square feet of flat area. Subtract this flat area amount from the total square footage to determine how much total stone you will need. You should allow an extra 5 -10% more stone for cutting and trimming on both corners and flats.
Materials You Will Need
1.
Mortar Components
Mix 1 part masonry cement (Type S) with 2 1/4 to 3 parts of masonry sand.
2.
Weather Resistant Barrier
Barrier should be equal to U.B.C. Standard No. 32-1 for asphalt saturated rag or U.B.C. Standard No. 17-1 for Kraft waterproof building paper.
3.
Metal Lath
Use a minimum 2.5 pound galvanized, diamond mesh, expanded metal lath. Rust inhibitive black metal lath may be used on interior applications. Or, you may use 18 gauge galvanized woven wire mesh. For metal buildings, use a galvanized, rib expanded metal lath (minimum 3.4 pounds 3/8”). Check your local building codes for other accepted lath or mesh.
4.
Fasteners
Use galvanized nails, staples, concrete nails or 1/4” type S-12 flat head screws.
5.
Masonry Sealer
When required, use a breathable type (non-film forming) sealer.
How To Prepare The Surface
Follow these guidelines in preparing different surfaces.
1.
Rigid Backwall, Wallboard, Plywood, Paneling and Wall Sheathing.
Use a weather resistant barrier to cover the sheathing, overlapping the joints 4” shingle fashion. Following local building codes, install mesh or lath. Galvanized nails or staples should be placed 6” on center vertically and 16” on center horizontally and driven into the studs at least 1”. Lath should be stopped 1” from the finished edges.
2.
Concrete, Masonry, Stucco, Block That Is Clean and Untreated.
No surface preparation is needed. Check new concrete surfaces for form oil. If form oil is present, use muriatic acid to etch the surface then rinse thoroughly and score the surface with a wire brush.
3.
Concrete, Masonry, Stucco, Brick That Is Dirty, Sealed or Painted.
Return surface to original condition by sandblasting or waterblasting (wash area to remove sandblast dust) or attach lath with concrete nails or masonry anchors. Use a bonding agent.
Step-By-Step Installation Instructions

Tips For Installing Tejas Textured Stone Over Masonry and Brick
For best results always use a bonding agent when installing Tejas Textured Stone directly over concrete, masonry, stucco, brick and block.
