Tools and Materials Required
Before beginning the installation, gather these essentials:
- Marble slab (cut to wall size)
- Notched trowel

Step-by-Step Guide to Installing Marble Slab on Walls
Step 1: Prepare the Wall Surface
Ensure the wall is:
- Clean and free from dust, grease, or debris.
- Flat and structurally sound.
- Primed (if necessary) to improve adhesion.
Step 2: Measure and Plan
Measure the marble slab size and dry-fit it against the wall to visualize layout. Mark alignment lines using a level.
Tip: Always plan from the center outwards for symmetry, especially in decorative applications like marble slab backsplash or shower wall cladding.
Step 3: Apply the Adhesive
Use a notched trowel to spread a layer of white thin-set or marble adhesive evenly on the wall.
Avoid grey mortar, as it may stain white marble slabs like Carrara or Calacatta Gold.

Step 4: Mount the Marble Slab
- Carefully press the slab onto the adhesive.
- Use spacers for even joints.
- Tap lightly with a rubber mallet to remove air pockets.
- Confirm vertical alignment using a level.
For large installations like marble slab shower walls, you may need additional support while curing.
Step 5: Let It Cure
Allow the adhesive to cure as per manufacturer’s recommendations (usually 24–48 hours).
Step 6: Grouting and Sealing
- Apply a non-sanded grout between the marble seams.
- Once dried, clean and apply a marble sealer to protect against stains and moisture.
- Buff with a soft cloth to enhance the finish.
