Instructions for Use
These items are generally glued and screw fixed. Watco Adhesive Mastic is ideal since it will make up minor deviations in the substrate and prevent the GRP drumming or rocking. Watco Adhesive Mastic should be applied to sound, clean dry surfaces if it is to be the only method of fixing in lightly trafficked areas. 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 (see below). Screw fixing should also be used if the GRP is likely to be trafficked before the Watco Adhesive Mastic has set.
A good quality abrasive disc, jigsaw or hacksaw can be used for trimming. 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.
When drilling holes in the GRP we do not recommend countersinking. When the screw is screwed down firmly, the screw head becomes embedded in the surface texture. The top of the screw head should be flush with the surrounding surface and therefore not present a trip hazard.
