Step-By-Step Guide

Installing large tiles could be tedious and requires a lot of patience. Ensure that you carefully follow the steps below.

  • Layout: First, create a layout without adhesive or mortar. Use a pencil to draw on the surface.
  • Measure the wall: Next, start measuring your wall from the center to balance the installation. Then, the next tiles go to the sides of the first one.
  • Cut the tiles: For smaller areas, cut the tiles into smaller parts and place them at the far end of the wall.
  • Seal the tiles: Seal the tiles using 511 Impregnator before installing to protect them from stains due to mortar.
  • Clean the wall surface: Cleaning the bathroom wall surface is important. Make sure to fix all holes and bumps before working on your project.
  • Install a level ledger board: Screw it to the wall to support the first row of tiles. Use the laser level to ensure the tiles are aligned during installation.
  • Mix the mortar: Follow the instructions on the packaging for mixing the mortar. Mix it in a bucket using the mixing paddle.
  • Trowel the mortar: Trowel the mortar to the surface. Hold the trowel at a 45-degree angle and cover the entire area. Trowel it in the opposite direction of the longest side of the tile.
  • Apply mortar on tiles: Use the flat surface of the trowel and apply a thin coat of mortar to the back of the tiles before installing.
  • Use leveling spacers: The leveling spacers keep the tiles from moving while curing. This is also to ensure that your wall is even and level before applying tiles.
  • Set the tiles: Set the tiles. Then, press them against the wall and carefully slide them up and down to ensure all the tiles' ridges are settled.

Finishing Touches After Installing The Tiles:

  • Remove the leveling spacers once the tile adhesive sets. 
  • Apply grout to the seams using the grout float. Flatten and wipe the excess grout as much as possible.
  • Let it settle for a few minutes, then come back later to remove excess grout using a sponge. Wipe the surface and prevent pulling too much grout from the seams.
  • Wipe the tiles with a wet sponge to clean them and to avoid grout haze, which is the excessive grout stain on the tiles.
  • Let the grout cure for 3 days before cleaning. Use a heavy-duty cleaner to clean any grout residue before sealing the tiles.
  • Sealing is important if you have natural stone tiles. Apply 511 Impregnator to the tiles, and you're done!
  • You may need to drill holes for light wiring and for a toiletries rack.

Tips And Tricks

  • Choose the right tiles for your bathroom. Don't just choose the color you want, also consider the materials, quality, and durability. Color and design are not enough to select the tiles you want to install.
  • Tiles have different water absorption. So, non-vitreous tiles absorb most water and should not be used in showers. However, semi-vitreous tiles have low absorption and are ideal for water splash areas. High-density glazed porcelain does not absorb water, which is perfect on bathroom floors and walls. Ask your dealer about tiles for the shower.
  • Layout your wall before installing tiles. Knowing symmetrical, level, and square installation is necessary to avoid mistakes. You wouldn't want to waste tiles and start all over again.
  • Use a pre-mix thinset mortar for high moisture areas.
  • There are parts where you need to cut and install the cut tiles. Place them towards the far wall and hidden from visible areas. 
  • Use a water-resistant grout because it allows water to pass through without breaking down.
  • In a grouting application, work the grout float in a diagonal motion.
