FAQ - ComposiGrip™ Non-slip Stair Treads

Frequently Asked Questions

1. Can ComposiGrip Non-Slip Stair Treads be Installed on Wooden Steps?

Yes — you can install the ComposiGrip Non­­Slip Stair Tread product on wooden steps, but there are important conditions and considerations to ensure it’s done correctly and safely.

⚠️ Important conditions to check

Before proceeding, you’ll want to verify these:

Structural integrity of the wooden steps

The tread cover itself is not meant to carry the structural load of the step — it relies on the step underneath.

“Step Cover is not designed to bridge large voids or gaps. The load-bearing capacity of each Step Cover is dependent upon the load-bearing capacity of the step it is covering.”

If the wood step is rotten, warped, cracked, or has large gaps/voids, those must be repaired or replaced before installing the cover.

2. Can ComposiGrip Non-Slip Stair Treads be Installed on Painted or Stained Steps?

If using stainless steel fasteners, paint or stain will not affect the installation of ComposiGrip Non-Slip Stair Treads. If you plan to use construction adhesive for the installation ensure the surface is clean, dry and level before installing. Lightly sanding the step and the back of the step cover can help create a stronger adhesion. Finish the installation with stainless steel fasteners.

3. What Adhesive is Recommended for Installation on Wood, Concrete and Steel Steps?

We recommend a premium PL adhesive or equivalent high quality construction adhesive. Ensure to follow the adhesive manufacturer’s instructions carefully for best results.

Using a plastic shovel for removing snow on exterior installations is recommended, as metal shovels may scratch the step cover.

ComposiGrip stair treads are available in the standard length of 48’’. If you require shorter lengths you may purchase custom cut stair covers here. Alternatively, ComposiGrip Non-Slip Stair Treads are easily cut to length using a circular saw with an abrasive cutting blade/diamond blade.
