Step-by-step Instructions for How to Tile Outside Corners Without Trim

Step 1: Inspect the Corner

Before beginning any tiling project, assessing the corner for damage or other problems that may need repair is best. Ensure there is no loose mortar and everything is level and even before continuing. Once you have inspected the corner, use a tile saw to cut two pieces of tile for each side of the corner. Make sure all pieces fit before continuing to the next step.

Step 2: Attach the Tile

Use a tile adhesive or mortar to attach one piece of tile on each side of the corner. It is important to use an appropriate amount of adhesive so that it will bond correctly and not crack when dry. Once you have placed the adhesive, set each piece of tile in its place. Use a level to make sure they are even, and then use spacers if desired to ensure that there is a consistent gap between tiles.

Step 3: Grout the Tile

Now it is time to grout the tile. Make sure you use an appropriate grout color and texture for the tiles you use. Apply the grout with a trowel, making sure it is fully pressed into all the gaps between tiles. Once you have completed the grouting process, use a damp sponge to remove any excess grout that has been left behind.

Step 4: Allow the Grout to Dry

Let the grout dry and set for at least 24 hours before continuing. This will ensure that it reaches its full strength. Once the grout is completely dry, you can apply a sealer to protect the tile from water and dirt. To finish the project, use a silicone-based caulk to fill in any gaps or cracks along the edges of the tiles. Make sure it is applied evenly and smoothly.

Step 5: Enjoy Your New Tiles

You are now ready to enjoy your new tiled corner! The job may have seemed tedious, but it is sure to pay off. These steps will help you achieve a beautiful tile corner without the need for trim or other additional materials. With just a few supplies and some time, you can easily create perfect corners.

What is the Best Technique for Tiling Outside Corners Without Trim?

The best technique for tiling outside corners without trim is to use internal corner pieces specifically designed for this purpose. These pieces come in a variety of sizes and shapes to fit different types of tile, allowing you to create a seamless look where two edges meet at an angle.

To install the guard, line up the edge of the guard with the edge of the tile and press it firmly into place, making sure that it fits snugly. Once installed, grout around the corner pieces to ensure a secure fit.

Another effective technique for tiling outside corners without trim is to use bullnose tiles. These are tiles that have been shaped and finished on one side so that they can be used for outside corners. To install, place the bullnose tile where two edges meet and press it into place. Then, use a wet saw to cut off any excess material so that the edge is flush with the other tiles. Once done, grout around the edge of the tile to secure it in place.

Are There Any Special Techniques for Cutting Tiles for the Corners of an Outside Wall Without Trim? 

When tiling an outside wall corner without trim, you will need to use a combination of techniques to achieve the desired look. First, you’ll need to determine how much material is needed for the job and then select the correct tiles for your project.

You should also ensure that the tile layout allows for extra space at each corner where the tiles will meet. Next, you’ll need to create a template for the tile cuts. To do this, you can use thin cardboard and trace out the shape of the corner with a pencil.

Once you have your template cut out, use it as a guide when cutting your tiles. You may also want to draw chalk lines on your wall to ensure you properly line up your tiles. When it comes time to cut the actual tile, you’ll want to use a wet saw or a handheld tile cutter for larger pieces.

If using a wet saw, make sure that it is equipped with an adjustable rip fence so that you can adjust the angle of your cuts without having to start over. You can also use a handheld tile cutter or nippers for smaller pieces.

What Are the Best Practices for Cleaning and Maintaining Tiles in an Outside Corner Without Trim?

Having outside corners without trim may look aesthetically pleasing, but it does require some extra attention to ensure that the tiles remain clean and in good condition. Here are a few best practices for cleaning and maintaining tiled outside corners without trim:

  • Cleaning Tiles Regularly: Dirt and other debris can accumulate on tile surfaces, especially in outside corners. Cleaning tiles regularly with a mild detergent and warm water can help prevent dirt buildup and reduce the risk of staining or discoloration.
  • Sealing the Tiles: Sealing the tiles can help protect them from damage caused by moisture, spills, and stains. Look for a sealant that is specifically designed for outdoor tile, and apply it according to the manufacturer’s instructions.
  • Repairing Damaged Tiles: If a tile is cracked or otherwise damaged, be sure to repair it as soon as possible to avoid further damage. This may involve replacing the entire tile or simply applying an adhesive to fill in any cracks.

By following these best practices, you can keep your tiled outside corners in tip-top shape and look great for years to come! With proper care and maintenance, your outdoor tiles will truly shine.

How Long Does It Usually Take to Tile an Outside Corner Without Trim? 

Tiling an outside corner without trim usually takes two to three times longer than tiling a standard inside or outside corner with trim. This is because the process requires more precision and care when cutting tiles to fit the exact angle. On average, it can take anywhere from 2 to 4 hours to tile an outside corner without trim, depending on the size of the corner and the complexity of the cuts.

To ensure that you get a perfect fit, measure each tile multiple times before cutting. You may also want to practice making test cuts on scrap tiles first to get an idea of how much material needs to be removed. Additionally, some tile cutters offer specialized attachments or blades specifically designed for tiling outside corners without trim.

Practice Making Test Cuts on Scrap Tiles

Using these tools can help you get more precise cuts and a better-looking final product. When tiling an outside corner without trim, it’s important to take your time and be precise with each cut. With patience, the right tools, and some practice, you should be able to achieve professional-looking results.


In conclusion, tiling outside corners without trim is a great way to enhance the look of your home. It’s relatively easy to do and inexpensive. You don’t need special tools or materials, just the right technique, and patience. Start by measuring the area you want to tile, then lay down the tiles in a straight line to overlap them slightly. The next step is to grout the tiles, making sure to fill any gaps and joints.

Finally, you can use caulk or silicone sealant to help protect the corners from water damage. I hope this article has been beneficial for learning how to tile outside corners without trim. Make Sure the precautionary measures are followed chronologically.
