Ultra tough GRP for added grip on heavily trafficked steps
Watco Anti Slip GRP Treads are coated with a coarse carborundum grit which is extremely hard-wearing and provides superior slip resistance. Watco Anti Slip GRP Treads retain good slip resistance in the wet, making them an excellent choice for external applications. For uneven surfaces Watco Adhesive Mastic is recommended in addition to screw fixing to help prevent rocking or drumming.
|Properties||Highly durable, anti slip, chamfered edge to minimize trip hazards|
|Suitable for||Floors, ramps, steps|

|Primer required||No primer required|
The surface should be reasonably clean and dry if the Watco Adhesive Mastic is to be the only means of fixing. Badly dished or holed concrete etc. should ideally be filled. Watco Adhesive Mastic will take up minor undulations and imperfections.
If Application is to damp, dirty or friable surfaces or in very cold weather, use Watco Adhesive Mastic to bed the GRP item into place and then always screw fix. Screw Fixings are generally made at about 600mm intervals. Drilling through the GRP is easy using a standard twist drill suitable for wood or metal. Countersinking is not required.
If you need to cut the GRP product, a good quality abrasive disc, jigsaw or hacksaw can be used. The GRP material is quite tough to cut by hand, so if power tools are not readily available, please ask about our cut to size service.
If mechanical Fixing is required, the following may be used as a guide:
To timber: No.8 x 30mm zinc plated or stainless steel screws.
To steel plate: No.8 x 20mm self-tapping pan head Pozi stainless steel screws or No.8 x 20mm self drilling pan head Philips zinc plated screws.
To concrete: No.8 x 30mm zinc plated or stainless steel impact anchors (Hilti HPS-1 or similar).
To open mesh: Stainless steel or zinc plated saddle clips and domed head bolts suitable in length for the depth of the existing treads.
Lay the items in place to ensure that they fit. Trim using a jigsaw with medium cutting blades (Bosch TI01 AIF or similar are ideal).
Hold the GRP in place and drill holes 15mm in from each edge, one hole in each corner through the panel and into the substrate. A rawl plug will probably be required in a concrete base. The drill hole in the GRP does not need to be larger than that drilled into the substrate.
