Why Tiling Inside Corner is Difficult?

1. Extra Precision

Tiling inside corners is not a task for the faint of heart. While you can certainly get away with cutting 45-degree angles on walls and floors alike, tiling an inside corner requires extra precision. Not only must you accurately measure and cut pieces to fit each wall perfectly, but you must also be sure that everything lines up as it should and looks visually pleasing.

2. Attention to Detail

Another reason why tiling inside corners can be a challenge is the attention to detail required. It’s easy enough to lay tiles on flat surfaces, but when it comes to making sure those two walls fit together perfectly, you need to make sure that each tile is properly aligned and that the grout lines are uniform. This type of precision takes time and practice to get right, so be prepared for a bit of trial and error when you’re tackling this project.

What You Will Need

Before you can start tiling an inside corner, there are certain materials and tools which will be essential for success.

  • Tiles- You’ll need to choose the type and size of tile you want for the project. Be sure to pick tiles that are rated for use in wet or damp areas, such as bathrooms.
  • Tile Spacers- These will help maintain a consistent grout line between tiles while they are being installed. 
  • Mortar- To help secure the tiles in place and ensure they stay stuck to the wall.
  • Grout- To fill in any gaps between tiles and give them a finished look. Depending on your preference, you can choose either sanded or unsanded grout for this task.
  • Utility Knife- This will be used to cut the tiles.
  • Notched Trowel- This tool is essential for applying the mortar and spreading it evenly.

10 Ways How to Tile Inside Corners

1. Prepare the Area

First, you’ll need to prepare the area by making sure it is free of dust and dirt. This will help ensure that tiles adhere properly and look their best when finished. The area has to be clean, dry, and free of debris before you begin tiling.

2. Measure and Mark the Walls

Next, measure each wall where the tiles will be installed and mark them with a layer of painter’s tape so that you know exactly where they should go. This can help ensure that all your tiles are even when it comes time to install them.

3. Cut the Tiles

Using a utility knife, start cutting your tiles to the correct length for each wall. Start with one corner and then move on to the other side, making sure that all your measurements match up perfectly. It may also be helpful to use a straight edge or leveler when you’re cutting your tiles.

4. Apply the Mortar

Once you have cut all of your tiles, it’s time to start applying mortar. Use a notched trowel to spread the mortar evenly on both walls, making sure that it completely covers each area where the tiles will be placed.

5. Lay the Tiles

Once the mortar has been applied, start laying your tiles on each wall. Be sure to use tile spacers to keep grout lines even and consistent throughout. The tiles should fit snugly against one another.

6. Let the Mortar Set

After all of your tiles are in place, let the mortar set for at least 24 hours before proceeding with grouting. This will allow the tiles to adhere fully to the wall and give them more stability when you start grouting.

7. Mix Grout

Once the mortar has set, it’s time to start grouting. Mix the grout according to the instructions and apply it to each section of the tile. Use a rubber float or trowel to work the grout into all of the cracks and crevices between tiles.

8. Wipe Off Excess Grout

Once the grout is applied, use a damp sponge to remove any excess. This step is important for making sure that the finished product looks professional and uniform. The grout should be flush with the tiles, and any excess should be wiped away.

9. Let the Grout Set

Once all of the grout is applied, let it set overnight before proceeding. This will allow the grout to fully cure and adhere properly. Setting time may vary depending on the type of grout you’re using, so be sure to read the instructions carefully.

10. Finishing Touches

Finally, use a dry cloth to buff the tiles and remove any remaining residue or haze. Now your tiling job is complete! Enjoy the beautiful results, and take pride in knowing that you accomplished a job well done.

With these 10 steps, you’ll be able to easily and successfully tile inside corners of any room of your house. Just remember to take your time, measure correctly, and use quality materials throughout the process. With a little patience and effort, you can create beautiful results that will last for many years.

8 Safety Measures to Take When Tiling Inside Corners

Before you start tiling inside corners, here are 8 safety measures to take:

  1. Wear protective gear such as a respirator mask and eye protection when working with tile adhesive or grout. The gear will help protect you from inhaling particles that may be released into the air during tiling.
  2. Cover any pipes or cables in the corners with insulation material to prevent them from getting wet and damaged. Pipes and cables should always be protected when tiling inside corners.
  3. Cover the floor with a drop cloth or plastic sheeting to keep it clean and protect it from tile adhesive or grout that may get on it during installation. Covering the floor will also make it easier to clean up after the tiling is complete.
  4. Wear gloves when handling tile adhesive or grout, as they can both be harsh on the skin and eyes. Gloves will also help to protect your hands from any cuts or scrapes.
  5. Ensure that the corner is properly prepped and free of dirt, dust, and debris before starting the tiling process. This will ensure a smooth installation and better adhesion of the tiles. Dirt and debris can also interfere with the drying process.
  6. Use a grout rake or spacer to maintain the same size gap between each tile so that the finished product looks even and professional. Maintaining a consistent gap is especially important when tiling inside corners.
  7. When cutting tiles for inside corners, use tile nippers and score the surface with a carbide-tipped pencil before applying pressure to the tile in order to break it. This will help you achieve clean cuts and avoid any chips or cracks.
  8. Clean up all tools and materials after the tiling is complete to avoid any potential accidents or injuries. Additionally, if you are using a tile saw to cut tiles in the corner, make sure to unplug it before cleaning it up.

Following these safety measures will help ensure that tiling inside corners is safe and successful.
