ᐅ Creating Vinyl Stair Nosing Using a V-Groove Router Bit

I am familiar with grooves that are not only V-shaped but also rounded so that a round metal profile can fit inside for reinforcement (common in timber construction). This way, the hard surface material, which is often less than 1mm (0.04 inches) thick anyway, remains intact, with a bonded metal profile directly underneath. This should also work well as a stair edge. Surface hardness is provided by the remaining vinyl, and the metal ensures dimensional stability.

Hello everyone!
A well-glued stair edge is very durable and long-lasting.

This video shows how the assembly adhesive is applied to the front edge of the stair and also features the aluminum profile suggested in an earlier message (for worn steps).

Regarding the wear layer: If you are more concerned, you can choose flooring with a thicker wear layer or use a PU sealer to increase the wear layer’s durability.

How is a weak point supposed to develop there? Milling a 45° V-groove is basically the same as making a miter joint. The flexible wear layer bends, the substrate adjusts, then the 45° angles fit together tightly without any gap...

The image in post #2 does not show a V-groove, someone just ran a cutter through it.
