Description

Firm-Step® Heavy Duty GRP sheets bring maximum safety underfoot in heavy traffic industrial environments. Ideal for areas in constant use, Firm-Step® Heavy Duty GRP Sheets enable you to produce continuous slip resistant walkways and workspaces with hardly any downtime. The resin bonded ceramic grit surface offers the same superior durability as the Firm-Step® Heavy Duty GRP Step Covers. Available in four colours and in fine or coarse grades.

Recommended areas of use

  • Ramps, walkways, fire escapes, all staircases, mezzanine floors, train track crossings, areas of heavy foot traffic
  • Internal ramps and staircases
  • Ideal for wet or very cold areas where the application of a coating may be impractical. Also suitable to be used around oily machines and for chemically damaged floors

Features

  • Tough and hard wearing for continuous slip resistance that won’t rot, warp or corrode
  • Heavy wear, slip resistance for vehicles, forklifts and pedestrians
  • Extremely low slip potential (Wet PTV 70)
  • Available up to 2400mm x 1200mm with our free cut to size service. Or can be trimmed to size on site

We recommend screw fixing to most substrates, combined with Watco Adhesive Mastic to prevent rocking on uneven surfaces. Screws and fixing plugs and a free pre-drilling service are available if required.

Application

Preparation

Any damage or undulations to the substrate should be remedied to ensure that the flat sheet will be on a reasonably flat and even surface. If using an adhesive, the substrate must be clean and dry and free from oils, grease, dust and any loose particles. The underside of the sheet must also be clean and dry. Where the substrate is contaminated (e.g. by oil), mechanical fixing is essential. Prior to applying any adhesive, it is advisable to carry out a dry-fit first to ensure a suitable fit. 

Watco recommends a double fixing method for installing GRP anti slip sheets, consisting of a high strength adhesive or double sided tape such as Watco Mastic Adhesive or UltraBond Tape, both supplied by us, and mechanical fixings. Please note: Watco Tape Primer should be used with UltraBond Tape when fixing to unsealed, porous concrete, brick, stone, blockwork and surfaces prone to dust.

Mechanical fixing

Firm-Step® Heavy Duty GRP Sheets can be drilled and secured with stainless steel screws. Follow the preparation procedure prior to fixing: 

1. Always ensure that the screw length is slightly longer than the plug length to obtain a good fixing.

2. Use Watco Adhesive Mastic on the underside to prevent the GRP drumming and rocking on the substrate.

3. Fixing is generally recommended at approximately: 70mm from the front, 50mm from each side, 60mm from the back, at a maximum of 250mm apart.

4. 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.

Bonding

Watco UltraBond Tape is suitable for bonding to concrete, wood, metal and steel in conjunction with Watco Tape Primer for unsealed, porous concrete, brick, stone, blockwork etc. Watco Adhesive Mastic is also a sealant and can be used to seal around the edges and stop water lying between the sheet and the substrate. Water will not affect the sheets 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 sheet approximately 25mm in from the edges and then cross hatch at about 200mm apart.

Apply sufficient hand pressure to bed the sheet into position.

With Watco Adhesive Mastic, optimum bonding will be obtained after 24 hours (at 20°C).
