The short answer

Most stone veneer installations need a suitable substrate, water-management layers where required, lath or cement board, mortar or approved setting material, layout tools, cutting tools, and finishing supplies.

Can I install it myself?

Use these guideposts to decide if this is a DIY-friendly project for your skill level and setup.

Good fit for DIY

  • Comfortable with basic construction tools
  • Surface is sound, clean, and dry
  • Project is on low walls, steps, or contained areas
  • You can follow the manufacturer instructions closely

Call in a pro

  • High walls or structural concerns
  • Water intrusion or unclear substrate conditions
  • Fireplace clearances, tight cuts, or code constraints
  • Limited time or installation experience

What the project involves

A closer look at the work and decisions that usually determine whether the finished stone looks right.

  1. PrepareInspect the surface, water management, and substrate before material goes up.
  2. Plan and layoutDry lay your pattern, plan joints, and mark reference lines.
  3. InstallApply mortar, set stones, and maintain joint consistency.
  4. FinishTool joints, clean surfaces, and allow proper cure time.

What materials do you need to install stone veneer?

Direct Answer

Most stone veneer installations need the stone itself, a suitable substrate, water-management layers where required, lath or cement board, mortar or an approved setting material, layout and cutting tools, joint-finishing supplies, and safety gear. The exact list depends on whether the project is interior or exterior and what wall surface you are starting with.

Do not buy from a generic materials list until you know your substrate, exposure, and installation method.

Core Materials

Most projects involve some version of these:

| Material | Why it matters |
| --- | --- |
| Stone veneer flats | Cover the main wall area. |
| Corners | Finish outside edges, columns, returns, and fireplace sides. |
| Caps, sills, or hearthstones | Finish tops, ledges, transitions, and fireplace bases when needed. |
| Mortar or approved setting material | Bonds the stone to the prepared surface. |
| Suitable substrate | Gives the mortar-set stone a proper base. |
| Layout supplies | Help balance colors, shapes, and cuts before setting. |
| Cutting tools | Fit pieces around edges, outlets, corners, and openings. |
| Cleaning supplies | Help clean mortar smears and protect the finished face. |

Exterior-Only Or Exterior-Common Materials

Exterior walls need water-management planning. Depending on the assembly, materials may include:

  • WRB or water-resistive barrier.
  • Flashing at openings, roof intersections, and base conditions.
  • Rainscreen or drainage mat.
  • Weep screed or drainage exit detail.
  • Metal lath.
  • Scratch coat mortar.
  • Exterior-compatible fasteners.
  • Mortar or approved exterior setting material.

These layers are not decorative. They protect the wall behind the stone.

Interior Materials

Interior dry-area projects usually need fewer water-management layers, but they still need a proper backing.

Interior projects may require:

  • Cement board or another approved backing.
  • Masonry-compatible fasteners.
  • Mortar or approved setting material.
  • Outlet box extenders.
  • Tape or temporary support for small pieces.
  • Drop cloths and cleaning supplies.

Fireplaces need extra attention to appliance clearances, substrate suitability, hearth details, and mantel transitions.

Tools And Supplies People Forget

Common forgotten items include:

  • Extra grout bags.
  • Buckets and mixing paddle.
  • Margin trowel and notched or masonry trowels.
  • Level and chalk line.
  • Masonry saw, grinder, or appropriate cutting tool.
  • Dust control and eye/respiratory protection.
  • Sponges, brushes, and clean water.
  • Painter's tape or temporary supports.
  • Outlet box extenders.
  • Extra material for cuts and layout waste.

Small missing supplies can slow the job more than people expect.

Materials By Starting Surface

| Starting surface | Materials question |
| --- | --- |
| Framed exterior wall | What WRB, flashing, drainage, lath, scratch coat, and weep details are required? |
| Block or cinderblock | Is the masonry sound and clean enough to bond? |
| Cement board | Is it rated, fastened correctly, and compatible with the setting material? |
| Brick | Is the brick sound, clean, and suitable to cover? |
| Stucco | Is the stucco stable and compatible with the new assembly? |
| Drywall | What approved backing is needed before stone can be installed? |

Common Mistakes

  • Buying stone flats but forgetting corners.
  • Forgetting caps, sills, hearthstones, or trim transitions.
  • Treating exterior water-management materials as optional.
  • Using generic construction adhesive without approval.
  • Forgetting outlet extensions on interior projects.
  • Not buying enough material for cuts and layout.
  • Starting before the substrate is identified.

Product Or Project Notes

RockSolid Veneers projects should be planned as a complete material package, not just square footage of flats. Current product content lists masonry-type surfaces and mortar-based installation options, but the final material list should match the actual project surface and exposure.

When in doubt, gather project photos, surface details, and measurements before ordering.

FAQ

Do I need metal lath for every stone veneer project?

No. It depends on the substrate and assembly. Lath with scratch coat is common for some wall systems, while masonry, block, or cement board conditions may be handled differently.

Do I need a rainscreen?

For many exterior installations, a drainage plane or rainscreen may be needed or strongly recommended. Check local code, climate, substrate, and manufacturer guidance.

Do I need special mortar?

Use mortar or setting material approved for the product, substrate, and environment. Do not assume generic glue or adhesive is acceptable.
