The success of your rock siding project depends heavily on proper surface preparation. Learn how to prepare different types of surfaces for rock siding installation. The main goal is to create a clean, stable base that will allow the mortar to adhere correctly.

Framed Exterior Walls

Are you working with a framed exterior wall, perhaps with plywood paneling, wall sheathing, or flush metal siding?

Cover with Weather-Resistant Barrier: Start by applying a layer of weather-resistant barrier, such as tar paper, over the entire surface. Overlap the joints by at least 4 inches in a shingle fashion to prevent water intrusion.
Install Metal Lath: In accordance with local building codes, install metal lath on top of the weather-resistant barrier. Use galvanized nails or screws, spaced 6 inches apart vertically and 16 inches apart horizontally, ensuring they penetrate the studs by at least 1 inch.
Finishing Touches: Stop the metal lath 1 inch from finished edges. Wrap all corners, overlapping the metal lath by at least 4 inches to provide extra support and protection against moisture.

Framed Interior Walls

For framed interior walls made of plywood, sheetrock, green sheetrock, or fiber cement board:

Install Metal Lath: Attach metal lath directly to the wall surface. Use galvanized nails or screws, spaced 6 inches apart vertically and 16 inches apart horizontally, penetrating the studs by at least 1 inch.
Finishing Touches: Stop the metal lath 1 inch from finished edges. Wrap all corners, overlapping the metal lath by at least 4 inches. Note that using expanded metal lath on fiber cement board may not be necessary unless required by local building codes.

Concrete Exterior or Interior Walls

When dealing with concrete, masonry, or stucco walls:

Clean the Surface: Ensure the surface is clean and free of paint, debris, or any coatings. Inspect new concrete for release agents (form oil), which must be removed by etching the surface with an etching agent.
Remove Paint: If the surface has been painted, sandblast or strip the paint completely.
Install Metal Lath (if necessary): If cleaning the surface is too difficult, you can affix metal lath using concrete nails. Space the nails 6 inches apart vertically and 16 inches apart horizontally, penetrating the concrete sufficiently to hold the lath securely.
Finishing Touches: Stop the metal lath 1 inch from finished edges. Wrap all corners, overlapping the metal lath by at least 4 inches.

By following these surface preparation steps, you’ll create a solid foundation for your rock siding, ensuring a beautiful and long-lasting result.
