Tiles installation onto Existing tiles?

You can choose to have fresh tiling appearance if your floor is starting to seem worn or if you’re sick of its old design.

Instead of ripping out your existing tiles and re-tiling your floor or wall, tiling over existing tile is typically a more simpler and less expensive choice. This has the benefit of removing the requirement for debris cleanup, reducing noise pollution, and preserving structural integrity without interference.  Additionally, pulling out the old tiles reduced labour hours, allowing for considerably quicker completion and completion of the project.

It is crucial to check the current tiles to make sure they are adhering properly to the substrate. When tapped, tiles with good adhesion do not produce a hollow sound. It is preferable to tap each tile with the back of a screwdriver and listen for a hollow sound to determine whether or not it is hollow. It is suitable for tiling over if the tiled area is 95% free from hollow noises. Remove any localised loose tiles and clean the area.

Now you may begin the retiling work. When putting tile over tile, the following measures might be helpful advice:

• Use soap and water to wash the existing tiles to get rid of any wax, sealants, and grime. Clear the surface with water, then allow it to air dry.

• Combine and apply thin-set adhesive on a prepared tile surface that can be covered throughout the adhesive’s open period.

• To guarantee a perfect adhesion, push the fresh tiles against the adhesive while twisting them.

• When tiling a wall, a minimum combined weight of 32 kilogrammes per square metre must be considered. The second layer will load the substrate after the first layer of tiles and glue, but before both layers have fully loaded the substrate.

• Floors with sufficient falls to avoid standing water and shaded outside walls are suitable.

• External applications such as high facades and walls, cantilevered verandahs or decks, and tiled driveways should not use “tile-on-tile” installations as these areas might be subject to severe pressures and motions.

• Ponds and swimming pools, as this is not advised as usual practise. (C2TES1) to install big format tiles over already-installed tiles.
