Stone can add a natural feel to an existing stucco wall.

Throughout history, stone has been a universal building material used for purposes ranging from structural to aesthetic. Most modern uses for stone are for aesthetic veneer applications, where the stone is applied to an existing wall, rather than constructing the wall structure itself. Stucco is a cement-like material that makes an ideal surface for stone veneer application. Applying stone over stucco is a generally straightforward task that just about anyone with a basic knowledge of masonry construction can complete.

Step 1

Rinse the stucco, using the garden hose to remove any dirt and debris. Scrub with the masonry brush as necessary.

Step 2

Mix the mortar in the wheelbarrow, using the shovel.

Step 3

Apply a thick layer (about 1 inch) of mortar to the back of a stone, using the brick trowel.

Step 4

Press the stone against the bottom edge of the wall; press hard enough so that a small amount of mortar squeezes out from behind the stone, leaving about a 3/4-inch mortar joint between the wall and the stone.


Step 5

Press more stones to the wall, working in horizontal rows and up the face of the wall.

Step 6

Mix the grout in the wheelbarrow, using the shovel.

Step 7

Load the grout bag with grout until the bag is a little more than half full, using the brick trowel as a scoop, then twist the top of the grout bag to close it.

Step 8

Apply grout to the joints between the stones, twisting the top of the bag. Work your way from the bottom of the wall to the top.

Step 9

Fill the 5-gallon bucket with clean water and soak the large sponge. Remove all excess grout from the stones and joints, using the large sponge. Rinse as necessary.
