Stair Treads: Frequently Asked Questions

Q: Why are the stair treads I received oversized?

A: Stair treads are usually supplied oversized, with untrimmed ends, to allow extra material to compensate for variations in step dimensions. It is a normal installation requirement to trim the stair treads for a proper fit.

Q: My stairs are only 10" deep but the stair treads all come 12" or more. Can I cut them to fit?

A: Yes. It's not cost effective to mold stair treads for every possible step size. You may notice the pattern molded into our rubber star treads does not continue all the way to the back of the tread. This allows for a trim fit without the need to make an unsightly cut thru the pattern.

Q: How do I trim my stair treads to fit my stairs?

A: Stair treads should be individually trimmed to fit each step, both in depth and from side to side. The rear cut should be made with a slight under bevel for a better fit. The stair treads can be marked with an awl and cut with a steel straight edge and a linoleum knife. Caution: do not apply a lot of force while cutting and be sure to keep all body parts clear of the knife, should it slip.

Q: Why are my existing stair treads cracking along the front edge?

A: During the installation, epoxy nose caulk should be used to fill any void between the step and the tread. This may be a result of worn or damage step. Even a slight difference in the shape of the front edge of the step and the molded shape of the stair tread could allow movement or flexing. This constant movement, no matter how small, is the reason for this unsafe condition. To prevent this on your next installation, apply a bead of #110 epoxy nose caulk along bend of the nose along the underside of the stair tread. The epoxy will expand and fill the voids and harden to prevent flexing and cracking.

Q: How do I prepare my steps for stair tread installation?

A: The surfaces of steps must be flat, clean, dry and free from oil, grease, rust, paint, varnish and old coverings, adhesives and any other foreign substance. Wooden steps should be thoroughly nailed or screwed down to avoid movement and defection. Worn or dished-out steps, cracks, holes, depressions or any irregularities on the step should be replaced or repaired by filling, sealing and smoothing with an appropriate leveling compound that will not crack or breakdown under normal use.

Q: What adhesives should I use for installing these stair treads?

A: If your stair treads are vinyl, you will need to use #400 neoprene contact cement. For rubber stair treads, you can use the #400 contact cement as well or any other suitable rubber flooring adhesive depending on the stair conditions.

Q: Do you provide other products not shown on web site?

A: Yes the products displayed on our website are roughly 20% of all the architectural products we have available. This 20% represents 80 to 85% of the products our customers purchase. It would be cost prohibitive for us and difficult to navigate our web site for the consumer if we put it all out there. If you are unable to find a product that properly meet your needs at, please use our free 888-432-2657 phone number for assistance or email us at You can also visit for commercial and industrial fabrications. 

Q: Color is very important to me, are stair tread samples available?

A: Yes, we understand how important color selection can be. We will provide stair tread samples upon request, free of charge.

Q: Why is the shipping cost not included when checking out from the site?

A: There are too many variables that determine the actual shipping cost; quantity, weight, size of package, ship to point and fuel cost. Prior to processing your order, we will have our shipping department confirm the best shipping method and cost. We will contact you with that cost and only process your order once we have your approval for the total charge.

Q: Are rubber and vinyl stair treads suitable for outdoor use?

A: Although this is commonly done, environmental factors, such as fluctuating temperatures, humidity, acid rain and UV rays can cause rubber and vinyl stair treads to harden and break down. The manufactures of these products do not recommend or warrant rubber and vinyl stair treads for use outside.

As an alternative, we offer the GSA Grit Surface Aluminum Stair Tread line.

Q: Do you have a matching landing tile for the vinyl stair tread #375?

A: Unfortunately, the vinyl stair tread manufacturer does not have a vinyl landing tile.

As an alternative, you may want to look at the M700 runner matting.
