How to Install Stone Veneer on a Stucco Wall

Overview

Stone is one of the oldest building materials still used today, although it is used differently in modern construction. Now builders use it as a veneer material instead of a structural one. Stone veneer can add a natural look to just about any structure. Stucco is a commonly used sheathing material on structures today and because it is a cementitious material, offers an optimum surface for stone veneer to bond with. The existing stucco replaces the need for a scratch coat that is usually applied to a wall before stone application.

Step 1

Rinse any dirt from the wall and scrub any debris from the wall using the six-inch masonry brush.

Step 2

Mix the mortar (as indicated on mortar packaging) using the electric drill w/ mixing paddle in the five-gallon bucket.

Step 3

Apply a thick layer (about one inch) of mortar to the back of a stone and press firmly to the wall, gently wiggling the stone so a small amount of mortar squeezes from behind the stone; repeat on following stones, working your way (in rows) from the bottom of the wall to the top. Wipe any excess mortar from the stones using a wet sponge, rinsing as necessary.

Step 4

Mix the grout (as indicated on grout packaging) using the electric drill w/ mixing paddle in the five-gallon bucket.

Step 5

Fill the grout bag about three quarters full and twist the top closed.

Step 6

Apply the grout to the stone joints, pinching the small opening of the grout bag to regulate grout flow and slowly twisting the top of the bag to retain pressure. Work your way from the bottom of the wall to the top.

Step 7

Wipe all excess grout from the stones using a wet sponge, rinsing as necessary.
