Flexible stone panels are designed to make real stone wall finishes much easier to install than traditional stone cladding or heavy stone tiles. Because the panels are lightweight, flexible and easy to cut, they are suitable for both professional installers and confident DIY users.
In this guide, we’ll walk through how to install flexible stone panels, including surface preparation, cutting, grab adhesive, positioning, curves, corners and common mistakes to avoid.

Tools & Materials Required
Before starting your installation, make sure you have the right tools and materials ready.
- Grab adhesive
- Tape measure
- Spirit level
- Pencil or marker
- Fine tooth blade for cutting
- Chop saw, circular saw, multi-tool, jigsaw or another suitable cutting tool
- Heat gun for curves or bending applications
- Cloth or brush for surface preparation
- Protective gloves and eye protection
For the cleanest cut, we recommend using a suitable cutting tool fitted with a fine tooth blade. This helps reduce rough edges and gives a neater finish when cutting flexible stone panels to size.
Step 1: Prepare The Surface
Good surface preparation is one of the most important parts of installing flexible stone panels. The wall or surface should be clean, dry, dust-free and structurally sound before any panels are fitted.
Flexible stone can be installed onto a wide range of suitable surfaces, including plasterboard, MDF, cement board, existing tiles, brickwork, render and exterior walls, depending on the project and adhesive used.
Before installation, remove any loose paint, dust, dirt, grease or unstable material from the surface. If the wall is uneven, repair or level the area first to help the panels sit flat and bond correctly.
Step 2: Measure & Mark Your Panels
Measure the installation area carefully before cutting. Mark the rear side of the panel using a pencil or marker where cuts are required.
Take your time during this stage. Flexible stone is easier to work with than traditional stone cladding, but accurate measuring is still important for a clean, professional finish.
Step 3: Cut The Panel To Size
Flexible stone panels can be cut using several suitable tools, including a chop saw, circular saw, multi-tool or jigsaw. The key point is to use a fine tooth blade wherever possible.
Cut slowly and steadily, supporting the panel properly as you work. A fine tooth blade helps create a cleaner edge and reduces the chance of damaging the stone surface.
Step 4: Apply Grab Adhesive
Once the panel has been measured and cut, apply grab adhesive to the rear of the panel. This can be applied in vertical lines, a zig-zag pattern or more fully across the back depending on the surface and installation area.
Make sure enough adhesive is applied to create a strong bond across the panel. Pay close attention to the edges and corners, as these areas need to sit securely against the wall.
Step 5: Position The Panel
Carefully position the flexible stone panel against the wall and check the alignment before pressing it firmly into place.
Use even pressure across the full surface of the panel and check it with a spirit level as you go. Make any adjustments straight away before the adhesive begins to set.
Step 6: Working Around Corners & Curves
One of the biggest advantages of flexible stone is its ability to bend around curved surfaces, corners and awkward areas. This makes it a strong option for feature walls, columns, curved counters, kitchen islands and commercial interiors.
For curved applications, gentle heat can be used to increase flexibility. A heat gun can help the panel bend more easily, but avoid forcing sharp bends too quickly.
Step 7: Joining Multiple Panels
When joining multiple flexible stone panels, the visibility of the joins can vary depending on the finish chosen.
Some designs naturally disguise joins better than others. Line Stone styles usually hide joins well because of the pattern running through the product. Travertine and slate finishes generally create a subtle join when fitted carefully. Rough granite styles may show joins slightly more due to the heavier texture.
Where required, a skilled installer can fill or blend the joints to reduce their visibility further.
Interior & Exterior Installation
Flexible stone panels can be used for a wide range of interior and exterior projects.
Popular interior uses include:
- Feature walls
- Media walls
- Bathrooms
- Kitchen walls
- Fireplace surrounds
- Commercial interiors
Popular exterior uses include:
- Garden walls
- Exterior feature walls
- Building facades
- Outdoor entertainment areas
- Commercial exterior projects
Always make sure the adhesive and surface are suitable for the environment, especially for exterior installations or areas exposed to moisture.
Common Installation Mistakes To Avoid
- Installing onto dusty, dirty or unstable surfaces
- Using the wrong adhesive
- Rushing measurements before cutting
- Using a rough blade instead of a fine tooth blade
- Not applying enough pressure when positioning the panel
- Forcing bends without using gentle heat
- Not checking alignment before the adhesive starts to set
Final Thoughts
Flexible stone panels offer the appearance of real stone without the weight, mess and difficulty of traditional stone cladding. With the correct surface preparation, clean cutting and suitable grab adhesive, they can be installed to create a premium stone finish across a wide range of interior and exterior projects.
If you are unsure which finish is right for your project, we recommend ordering a Flexistone sample pack before placing a full order.
