Customer Questions & Answers

is this galvanized steel?

Asked by: dg
The Eureka model is electro-statically galvanized with a finish paint top coat that is powder coated. It is designed to be used in exterior installations. We recommend however if the installation is in a coastal region, close to the ocean, you use the Enduro Steel which is hot-dipped galvanized to withstand the harsher environmental conditions with the high salt air content.

What glue do you suggest using to adhere stair tread covers?

The tape that was included is useless and I tried some glue but all have blown off in the wind!! Very frustrating for an expensive product. Would appreciate help.
Asked by: Mags
We are sorry for your frustration with the adhesion of the stair tread covers. The Eureka model can be installed in an internal or external installation. The 2-sided tape is included for the internal installations but is not adequate to withstand external climate elements. There should have been a drawing included with the pack of the stair tread covers suggesting a silicone adhesive and showing a S line type of application of the adhesive to the tread covers. We have found that customers have the best success when installing the stair tread covers if they will first use a light sandpaper to "scuff" the bottom side lightly of each tread cover and landing cover. This provides a little better surface for any adhesive to "bite" the PVC material used for the tread covers. We have also found that a high quality silicone adhesive works the best. There is a GE product called Silicone II that is used for Gutters & Flashings that has been an extremely effect product that will actually adhere to both PVC (tread covers) and to the metal (12 gauge steel) of the actual stair treads. Should you have any further questions or need additional assistance, our Customer Sales & Support team can be reached via our toll-free telephone number at (888) 782-4758 or via our email at We hope this information will assist you in completing your Eureka stair installation project and look forward to speaking with you if we can provide any additional assistance.
