In this month’s issue…
We are excited to announce that we are now fabricating and shipping Indiana Limestone Thin Veneer in smooth and split face flats and corners. Also be on the lookout for additional types of limestones that we will soon be adding to our product offerings. We also discuss installation of thin veneer limestone, have a new Project Spotlight, Ernie sounds off on Installation of Thin Veneer stone.

Adhered Natural Stone Veneer Installation Guide
Do This Before You Begin
Preliminary Step A. Concrete/Concrete Block/Stucco needs to be clean and in its original, untreated condition. If the surface has been treated, light sandblasting or waterblasting can be used to restore the wall to a smooth, clean surface. Remove all form-release agents, dust, etc., that may inhibit the mortar bond.
Preliminary Step B Alternately, you can securely attach metal lath to the wall every 6” on center and apply a scratch coat of mortar 3/8″-3/4″ thick. Use a toothed scraper, notched trowel or small piece of lath to lightly rake horizontal grooves in the scratch coat. Allow the scratch coat to cure for a minimum of 24 hours before installing adhered veneer.
Let’s Get Started
Step 1: Apply sheathing over the studs. Sheathing can be exterior OSB, plywood, exterior grade drywall, wallboard or cementitious board.
Step 2: Staple the building paper to the sheathing. Attach the building paper in horizontal strips. Start at the bottom and overlap 2” (like shingles). Overlap the vertical joints by at least 6”. If using flashing or support brackets (anchors), install them before proceeding to the next step.
Step 3: Screw, staple or nail the metal lath to the studs. Only the screws that attach to the studs are counted to meet code requirements. Overlap the metal lath at least 1/2” for horizontal and 1” for vertical joints. At corners, overlap the vertical joints at least 16” around the corner to avoid corner cracking. Use barbed galvanized nails at 6”o.c. vertically for exterior work or steel wire furring nails at 4”o.c. for interior work. Minimum nail penetration is 1” into the studs. For steel studs, the lath must be anchored with corrosion resistant screws that have a minimum shank diameter of 0.136”. (See Figure 1)
Apply a scratch coat that is 3/8” to 1/2” thick over and embedded into the metal lath. Use a toothed scraper, notched trowel or small piece of lath to lightly rake horizontal grooves in the scratch coat. Allow the scratch coat to cure for a minimum of 24 hours before installing adhered stone. (See Figure 2)
Our project spotlight this month are the Florence County Libraries. Constructed simultaneously in 2009 and located in Johnsonville, Timmonsville and Olanta South Carolina, these libraries showcase smooth veneer Indiana Limestone with fluted columns, profiled bases and hand carved ionic caps.
The contractor was FBi Construction of Florence, SC and the Project Manager was Kyle Gunter
