Watco Firm-Step® Precision Step Covers can be drilled and secured with stainless steel screws. Follow the preparation procedure prior to fixing:

  • Always ensure that the screw length is slightly longer than the plug length to obtain a good fixing
  • Use Watco Mastic Adhesive on the underside to prevent the GRP drumming and rocking on the substrate
  • Fixing is generally recommended at approximately: 70mm from the front, 50mm from each side, 60mm from the back, at a maximum of 250mm apart

If fitting to a metal substrate, use self-tapping screws. There is no need to counter sink the screw holes since the screw can be tightened so that it beds into the gritted surface, making it flush with the wearing surface.


Watco Adhesive Mastic is also a sealant and can be used to seal around the edges and stop water lying between the stair cover and the substrate. Water will not affect the stair covers but can affect the substrate such as wood or metal causing rot or rust. Watco Adhesive Mastic also offers a secondary fixing in the unlikely event that a mechanical fixing fails.

Run a bead of adhesive around the perimeter of the stair tread approximately 25mm in from the edges and then cross hatch at about 200mm apart. Apply sufficient hand pressure to bed the stair cover into position. With Watco Adhesive Mastic, optimum bonding will be obtained after 24 hours (at 20°C). However, stairs can be made available to traffic a few hours after bonding, but this is subject to temperature so it is worth testing first.

One 310ml tube of Watco Adhesive Mastic is sufficient for any one of the following:

  • 5 x 600mm wide step covers
  • 3 x 1000mm wide step covers
  • 2 x 1500mm wide step covers
  • 2 x 1200mm wide step covers
