Small tile installation and backsplash mosaics is a relatively simple job to accomplish, but the same is not true for large format tiles, which come in the size of 12X24, 18X18, 24X24 and 18X36. If you are looking to install large sized tiles on your wall, then you will have to follow the following tips to get it done the right way in the very first time.
Unlike small tiles, you need to make sure your wall is strong enough to support the weight of your ceramic. If necessary, screw down your gypsum, plywood or cement board so that the sheet is firmly anchored in the wood structure.
Also, check that your structure is solid: avoid laying large tiles on a wall of retractable door, unless it solidifies. Also, if your structure is moving, solidify there before laying your gypsum, plywood or cement board. If you have surface defects, take the opportunity to rectify the situation: you will save time for the future.
Finally, make sure that the surface you are going to stick on is clean and that the adhesion is good. Given the weight of these tiles, avoid sticking on greasy surfaces or painted with oil.
As large tiles are heavy, you will need to go from the floor to the ceiling. First, make sure your floor is level for which, you can draw a corrective line if necessary. Also, measure what will be your ceiling cut to see if you can start with a solid tile on the floor. Use crossbars to prevent the tiles from sticking together and getting uniform joints.
Normally, you will have to center your wall installation by drawing a centerline and checking what kind of piece it gives you on the sides, whether you will leave either side of the line or rather the center of the tile on the line of center.
To ensure a good adhesion, use an adequate trowel (3 / 8X3 / 8 or 1 / 2X1 / 2 as the case may be) and make a double bonding, i.e., to apply cement-glue on the wall with the serrated side of the trowel and on your tile with the flat side of the trowel. This method will also allow you to correct some surface defects. Finally, to ensure a flatter surface, use the Raimondi system.
In conclusion, if you follow these tips, you will not just get beautiful looking walls, but also the walls that will be strong and durable.
