Before installation: confirm the system
Different flexible-stone constructions and project exposures can require different primers, adhesives, tools and curing conditions. The project team should confirm the exact family, substrate and bonding route before site installation begins.
1. Prepare the substrate
The wall should be stable, clean, dry and sufficiently even for the selected finish. Repair loose areas, deep joints, high spots, powdery surfaces, moisture-affected zones and other defects before cladding.
2. Set out & cut
Mark reference lines, plan seams and corners, and dry-fit the important pieces. Decide where pattern direction should run before adhesive is applied. Cutting method depends on the selected product construction and thickness.
3. Apply the compatible adhesive
Apply the specified bonding system in the manner required for the material and substrate. Work within the open time of the adhesive and avoid creating unsupported pockets behind the finish.
4. Position & press
Place the sheet accurately, then press and consolidate it so the surface is fully supported by the bonding layer. On curves, work progressively rather than forcing the entire sheet into position at once.
5. Finish joints, edges and inspect
Complete the selected seam and edge detail, remove contamination before it cures, and review the surface under representative lighting. Check alignment, adhesion, corners, pattern direction and visible joints before the work area is released.
Flexible stone panel seams: choose the detail before bonding
Seams are a design and installation decision, not a defect to hide at the end. The best approach depends on the exact Lithvanta finish, backing, substrate, movement requirements, lighting and whether the wall is indoors or exposed. These are planning options, not universal installation specifications.
| Detail to evaluate | Where it may work visually | What to confirm before installation |
|---|---|---|
| Close-fitting joint | Quiet interior feature walls with a continuous texture | Cut-edge quality, pattern alignment, allowable movement and whether the selected system permits a tight joint. |
| Color-matched filled joint | Large textured walls where a consistent joint line is acceptable | Approved filler or sealant, compatibility, staining risk, cleaning method and the specified joint geometry. |
| Expressed joint or trim | Retail fit-outs, reception walls and deliberate panel grids | Trim profile, exposed edges, material transitions, visual spacing and movement accommodation. |
| Wrapped or terminated corner | Columns, curved returns and inside/outside corners | Minimum permitted radius for the exact finish, backing strain, cut edge, substrate shape and a physical mock-up. |
| Movement / building joint | Locations where the substrate or structure is designed to move | Carry the underlying movement joint through the finish using an engineered detail; do not simply bridge it with a decorative sheet. |
A five-point seam mock-up review
- Lay out full-size pieces: mark the intended seam positions and texture direction on the actual wall geometry.
- Check raking light: view the joint from typical entry points and under the lighting planned for the space.
- Test the real edge: use the proposed cutting and finishing method on the selected finish, not a different sample.
- Include the complete bond system: use the actual substrate, primer or adhesive candidate and specified joint treatment in a representative mock-up.
- Record the approval: photograph the accepted joint and note finish code, materials, location, approver and any unresolved performance requirements.
Example: on a hotel reception wall, a deliberately aligned vertical reveal may be more repeatable than trying to make every joint invisible. On a round column, a seam placed at a less-visible return may work better than a front-facing joint. Neither layout should be approved without checking the actual finish and radius. For geometry-specific planning, see our curved-wall and column guide.
Start with the Slate or Travertine & 3D Printed Stone finish families for appearance direction, then request physical samples to review the proposed joint under project lighting.
Common mistakes to avoid
| Mistake | Better approach |
|---|---|
| Bonding over a loose surface | Repair or remove unstable layers first. |
| Choosing adhesive generically | Confirm compatibility with both panel and substrate. |
| Ignoring pattern direction | Dry-lay and mark orientation before bonding. |
| Leaving seam decisions to the end | Plan seam locations during layout. |
| Skipping the mock-up | Use a representative sample / mock-up for critical geometry and finishes. |
Frequently asked questions
Can flexible stone be installed over drywall?
Potentially, if the drywall assembly is stable, properly finished and compatible with the selected primer and adhesive. Confirm the exact material and wall condition first.
Can it be installed over existing tile?
Sometimes, but only when the existing tile is sound and the preparation/adhesive system is suitable. Hollow, loose, contaminated or moisture-affected tile should not simply be covered.
Do all flexible stone products use the same adhesive?
No. Adhesive selection depends on product construction, substrate, environment and project requirements.
Should flexible stone panels always have a fixed gap between them?
No universal gap dimension applies to every flexible stone panel. The joint width, filler, edge detail and movement provision must be confirmed for the exact finish, backing, substrate and exposure. Do not cover a structural movement joint without an approved detail.
