Step-by-Step Preparation and Installation Guide for Porcelain Shower Slabs

A GUIDE TO INSTALLING PORCELAIN SHOWER WALLS: 

1. Design and Planning:

   • Determine the layout and design of the shower walls.
   • Measure the dimensions of the walls to calculate the quantity of porcelain slabs needed.

2. Material Selection:

   • Choose the desired porcelain slabs, considering color, pattern, and size.

3. Preparation:

   • Ensure the existing walls are clean, dry, and in good condition.
   • Repair any damage or imperfections on the walls.

4. Waterproofing:

   • Apply a waterproofing membrane to the walls to protect against water damage.

5. Substrate Installation:

   • Install a cement backer board or similar substrate over the waterproofing membrane. This provides a stable surface for the porcelain slabs.

6. Layout and Cutting:

   • Plan the layout of the porcelain slabs, considering any cutouts for fixtures.
   • Cut the slabs to fit the dimensions of the walls using a wet saw or other appropriate tools.

7. Adhesive Application:

   • Apply a thin-set adhesive to the back of each porcelain slab and press it onto the prepared substrate.

8. Leveling and Alignment:

   • Ensure each slab is level and properly aligned with adjacent slabs.
   • Use spacers to maintain consistent gaps between slabs for grout lines.

9. Grouting:

   • Once the adhesive has cured, apply grout between the porcelain slabs using a rubber float.
   • Wipe off excess grout with a damp sponge.

10. Sealing:

    • Seal the grout lines and the surface of the porcelain slabs with a suitable sealer to prevent water penetration and staining.

11. Curing:

    • Allow the installation to cure according to the manufacturer's recommendations.

12. Final Inspection:

    • Inspect the completed installation for any imperfections or areas that may need touch-ups.

It's important to note that the specific steps may vary based on the manufacturer's recommendations and the characteristics of the porcelain slabs being used. Professional installation is recommended for ensuring a successful and durable outcome.
