When finishing a tiling project, one detail that often raises questions is the positioning of the tile edge trim: should it sit perfectly flush with the tiles, or is it okay for the trim to be slightly raised or recessed? 

Many factors come into play when it comes to fitting tile trim: the size of your tiles, the area, and your preferred style. This article explores the importance of fitting tile trim flush to your tiles and provides our expert guidance on achieving a professional finish for your tiling project.

Should Tile Trim Sit Flush with the Tile Surface?

Ideally, yes, tile trim should fit flush to your tiles. Not only does this create a smooth, seamless appearance for your tiling, but it also protects the edges of your tiles, extending their lifespan and delivering a professional finish. 

Should There Be a Gap Between Tile Trim and Tiles?

Although some intentionally opt for a bolder design and want the tile trim to sit proud to frame their tile feature, ideally, there should be no gap between the tiles and trim. The purpose of a tile trim is to strengthen and protect your tiles. If it doesn’t sit flush, it’s not doing its job effectively. 

Pros of Flush-Fitted Tile Trim

• Increased hygiene: A flush trim means zero gaps for dirt, dust or grease to gather and lead to rising levels of harmful bacteria. When your tile trim sits flush against the tile surface, you can easily and effectively clean both the tiles and their edges.

• Extends durability: When the trim sits correctly on your tiles, it helps protect the integrity of your tiles. Tight-fitted tile trims strengthen vulnerable tile edges from chips, cracks, and general wear, ensuring a higher and longer return on investment. 

• Smooth, safe edges: Depending on where your tiles are positioned, exposed tile edges can cause serious problems. Tile edges can be quite rough. So, a well-fitted tile trim provides a smooth edge, eliminating the risk of cuts, scratches, or clothing being caught on jagged edges. 

• Professional finish: Ultimately, whichever type of tile trim you choose, it indicates a job well done. When the trim sits flush with the tiles, it creates a professional look and adds that finishing touch for a lasting visual impact.

Cons of Non-Flush Tile Trim

• Dirt build-up: When tile trim doesn’t sit flush to the tile surface, gaps are exposed. This is a prime spot for dust, dirt, and grease to accumulate. These areas can become difficult to clean, leading to discoloured and unhygienic tiles and surfaces. 

• Messy appearance: Loose or poorly fitted tile trim also has a negative aesthetic appearance. To onlookers, your tiling project may look incomplete. Furthermore, your tiles are at risk of discolouration and losing their allure. 

• Increase tile cracks or movement: Tile trim helps keep your tiles in place. If it is not installed correctly, your tiles are at risk of cracking, damage, or movement. These issues can then become bigger, costlier fixes later on.

3. Precut your tile trim: Measure the length and width of the area you’re tiling and precut your tile trim before you start. This ensures you have enough trim to complete the job.

4. Check as you go: Use a spirit level and tile spacers to ensure everything lines up before the adhesive sets. 

5. Fit trim the right way round: One common mistake is fitting the trim the wrong way round. Apply adhesive to the thinner part of the trim and slot it behind the tile. Push the trim into place until it sits comfortably and flush with the edge of the tiles.
