Inside Create an accent wall or enhance a divider or fireplace.  Stone Veneer can be applied to any soundly constructed interior surface-plywood, drywall, plaster.  First, completely cover surface with 15 LB felt paper as described in OUTSIDE instructions. Outside Goes great on ordinary wood siding First completely cover wood surface with standard 15 lb felt paper before installing metal lath in step 1.  Overlap felt by 2" on horizontal joints; 6" on vertical joints.  This will moisture-proof your wall.

Brick or Concrete Block (Inside or Outside) If wall has been painted or sealed, install metal lath as in step 1.  If wall has never been painted or sealed, wash thoroughly and begin installation with step 3.





Stone: Height x width of area to be covered minus openings= Total sq.ft. needed.


Corners: Total length of all outside corners to be covered divided by 10 = no. of boxes of corners.


Hearthstone: Width x length= sq.ft. to be covered divided by 2-1/2 sq.ft. per hearth piece = no. of hearthstones


Materials Needed per 100 sq.ft.:


Type "S" Mortar..............................................3 Bags


Color:.............................................Based on masonry


Sand...............35 Gallons of clean sand approx. 350 lbs.


Materials Also Needed on Wood Construction:


1 3/4 Galvanized roofing nails


#2.5 diamond wire lath


Felt Paper, 15lb standard




1 Install Metal Lath Metal Lath is diamond type 27" wide and 6" long.  Install the lath sheet horizontally across the wall.  The wire diamonds in the lath form packets and these pockets must be turned up to catch and hold our mortar.  To check this, run your hand down the lath from top to bottom. It will feel smooth going down and very rough going up. Nail the lath to the plywood, drywall, etc. bending lath around corners.  Use 1 3/4" galvanized roofing nail, making sure they go into the studs at least 1".  Studs are placed 16" apart in most construction.  On a nailable surface, use a 6" nailing pattern.  On drywall or foam board type surface, nail securely on studs every 4 inches.  It is important that the lath be kept flat against the wall.  No sags or bulges.  Trim away excess lath.  If applying lath to masonry use 1/2" masonry nails in a 6 inch pattern.  Galvanized wire lath is preferred for exterior applications.


2 Mix Your Cement And Apply (Scratch Coat) Use only if nailing is not possible between studs.  Mix one bag of Type "S" mortar with twelve gallons of clean masonry sand.  Add water to blend to a creamy, paste-like mixture (should be sufficient to install 80 sqft. of stone).  Spread a thin layer of this mixture to cover the lath in the center area between studs.  Allow to dry and this will provide a rigid backing for your stone and assure firm bonding of the stone pieces.


3 Apply Stone Veneer If an outside is involved on your job, the corner should be installed first.  After installing the corner pieces, work away from the corner using regular stones, mixing large ones with smaller ones for the most pleasing effect.  Keeping this in mind, mix concrete exactly as in Step 2.  Now, take a stone and apply the mix over its back about1/2" thick, letting the mortar "cone up" in the center.  Place the stone against the wall and wiggle it from side to side.  This will set the stone.  If the mix is the right consistency, the stone will stay in place.  Adjust the mix if necessary.  Now install the other stones keeping a 3/4" space (joint) between them.  If needed cut or trim the stones using a trowel or nippers, or even an old hatchet.  As you work, use a clean, wet sponge to wipe any excess mortar from face of stone.


4 Mix The Grout And Fill Joints After stone pieces are set in place, apply grout to joints.  You may use the same mix of mortar and sand for the grout.  If color is desired, follow instructions on color box.  Fill your grout bag with about a quart of the mix.  Twist the bag to force the grout out of the hole in the end.  Hole should be about 1/2" in diameter.  Apply firm even pressure to allow the mix to enter the joints in a nice smooth bead.  Keep the bag moving along the joint areas keeping the mix off the face of the stones as much as possible.  If dripping occurs, clean the stone with a clean, wet sponge.  Never use acid for cleaning.


5 Finish Or Strike The Joints As grout mix begins to firm, use a flat wooden stick rounded at one end to strike or level the grout joints.  Be sure to fill all holes, gaps or openings, and run the stick around the edge of each stone to seal the mortar to the stones.  Now sweep all joints and stones with a brush to eliminate loose particles.  SEALING (OPTIONAL AND NOT NECESSARY ON MOST JOBS.)  Sealing can be accomplished using a good grade of masonry sealer.  Give the wall time to dry, then follow manufacturers instructions.
