No more chipped corners!

We have kids running around the house, and our old tile corners were constantly chipping. This metal trim provides excellent protection and still looks sleek. Highly recommended for high-traffic areas.

Professional results for DIYers

I was worried about installing this myself, but the putty-style edge made it forgiving. It covers uneven tile cuts perfectly. My kitchen backsplash looks like a pro did it.

Perfect for modern minimalist bathrooms

The ultra-narrow profile is exactly what I needed for my bathroom renovation. It disappears into the grout line beautifully, giving a very clean look without the bulky plastic trims of the past.

Invisible finish achieved

If you want that seamless look where the tile just turns the corner without a visible strip, this is it. The narrow edge is barely noticeable once grouted. Very happy with this purchase.

Good value for the price

Solid product. The only reason I didn't give 5 stars is that shipping took a bit longer than expected, but the product itself arrived in perfect condition with no dents.

Great quality, requires careful cutting

The aluminum feels very sturdy and the white finish takes paint well if you need to match a specific wall color. Just make sure you use a fine-tooth saw blade to avoid scratching the surface during installation.

5 FAQ

Q: What is the actual visible width of the trim after installation?

A: Once installed and grouted, the visible face of the trim is approximately 3mm wide, providing an ultra-narrow aesthetic that blends seamlessly with standard grout lines.

Q: Does this come with adhesive or do I need to buy it separately?

A: The trim is installed by embedding it into the tile adhesive or mortar bed during the tiling process. Adhesive is not included in the package, as the type required depends on your specific tile material.

Q: Can this trim be painted to match my wall color?

A: Yes, the matte white finish is specifically designed to be paintable. We recommend using a primer suitable for metal before applying your chosen latex paint for the best adhesion.

Q: Is this suitable for wet areas like a shower stall?

A: Absolutely. The aluminum alloy is anodized to resist corrosion and rust, making it ideal for high-moisture environments such as showers, bathtubs, and splashbacks.

Q: What tool is best for cutting these aluminum strips?

A: For straight cuts, a miter saw with a non-ferrous metal cutting blade works best. For smaller adjustments, a high-quality hacksaw with a fine-tooth blade can also be used effectively.
