The paint will continue peeling effecting building aesthetic 2. Plaster and brick of wall will be exposed to other factor such dampness without a layer of protection of paint. 3. Causing honeycomb at plaster making it more easier to deteriorate. Possible Causes 1. Lack of waterproofing between tiles and plaster from the inside of the toilet Remedies 1. Remove the grout line along the wall tiles using a grinder 2. After de-grouted the tiles in a reasonably sized area, the tiles can be removed. 3. Turning the chisel around, tap at the wall tiles with its handle, seeing if there a loose one that will come away more easily 4. Insert a flat tool between tile and the wall. Gently tap the handle of the tool with hammer until it comes away, making sure to have someone on hand to catch the tiles. 5. Clear the remaining grout away carefully using a putty knife. 6. Using a paint roller, start apply primer from the back corner and work the way around the walls to a height of about 20cm. 7. After the primer has dried, silicone seal all of the gaps between the floor and the wall. 8. Use a paint scraper to remove any excess silicone. Then let the silicone dry for 24 hours before you start waterproofing. 9. Use a roller to apply the waterproofing agent on the wall .Then apply it around the width of the paint roller where the wall meets the floor. 10. Cut the waterproof membrane into lengths of the bathroom walls. Lay the membrane down on the wall and the other half on the bathroom floor covering the crack. To stick the membrane , use either a paint roller or brush to paint over it with the waterproofing agent. Repeat this until all of the gaps on the wall are covered with membrane and painted over. 11. After covered all of the membrane on the walls with the waterproofing agent, paint the rest of the floor. Then leave it to dry for 24 hours. 12. After letting the waterproofing agent dry, apply a final coat of waterproofing to the walls with a brush or roller. let this second coat dry another 24 hours before it’s ready. 13. Prepare the adhesive. Apply the adhesive to the wall with a notched trowel, holding the trowel at about 45 degrees so the furrows of adhesive are uniform in height. Do not hide the layout lines with the adhesive. 14. Place the first row and column of tiles along the layout lines, pressing the tiles firmly and twisting them slightly to embed them into the adhesive. Do not slide the tiles into position. 15. Use tile spacers to set consistent gaps for grout joists, as needed. Most wall tiles have built-in lugs that automatically set the grout gaps. 16. Install the remaining tiles, working from the first row and column. 17. After the tile adhesive has fully cured. Apply the unsanded grout with a rubber grout float, pressing the grout firmly into the joint spaces. 18. Make a second pass diagonally across the tiles, holding the float at a steep angle, to remove excess grout from the tile surfaces. 19. Gently wipe the tiles and joiints with a grout sponge and clear water. Let the grout set up, then buff away any grout haze from the tile faces using a soft cloth. 20. Remove the paint in the affected area. Use a wire brush or paint scraper to scrape off all loose paint. 21. Sand the space in order to ensure a wall surface free of any grooves or lines. Use a very fine-grit sandpaper. 22. Using either a tack cloth or a lightly damp (not wet) sponge, wipe off the area to be painted; wipe again with a clean, dry rag and let dry thoroughly. 23. Cover the area with primer, allowing the surface to dry according to the manufacturer's directions. 24. Apply a first coat evenly over the prepared area.
