IF FIXING TO CONCRETE
1. Ensure that the concrete is structurally sound and is capable of receiving a mechanical fixing without crumbling away. If necessary use a proprietary concrete repair compound.
2. Ensure that the area is not worn or uneven. Concrete steps can sometimes be 'dished' or lower in the middle of the step. If necessary use a proprietary concrete repair compound.

IF FIXING TO TIMBER
1. Ensure that the wood is sound and capable of receiving a mechanical fixing. Rotten timbers will need to be replaced before overlaying GRIPFAST Products.

IF FIXING TO METAL
1. If a bond only fixing is required, ensure all loose paint and any rust is removed prior to installaion.

2. If possible, prior to installation, lay the panels out in place to check they fit properly. Once you are happy you can carry out the fixing.

IF FIXING TO CONCRETE
1. The recommended methodology for fitting to concrete is to use both an MS Polymer adhesive mastic and mechanical fixings.
2. Lay the panels into position, drill through the panel with a masonary drill bit. Lift the panels and insert plugs.
3. Fixing positions should be placed 50mm in from the edge and at approximately 300mm centres thereafter (see drawing).
4. Apply the adhesive / mastic in a bead to the underside (non gritted side) of the panel 25mm in from all edges and in a in wave pattern across the whole panel (see drawing).
5. Lay the panels into place, taking care to line up with the plugs and screw the panels into place with 1.5" no.10 stainless steel screws.
6. If laying multiple panels allow a nominal 5mm - 8mm gap between each panel edge and fill the gap with the MS Polymer mastic.
7. If required, lay a bead of MS Polymer mastic around the outer edge of the panel to stop water ingress.

IF FIXING TO TIMBER
1. Installation is the same as for concrete, but plugs are not required.
2. Use 1.5” No. 10 Stainless Steel woodscrew .
3. If fitting to a particularly hard hardwood, it is sometimes necessary to pre-drill the timber to reduce chances of shearing off the stainless screw.

IF FIXING TO CHEQUERPLATE & FLAT STEEL
1. The recommended methodology for fitting to steel is to use both an MS Polymer adhesive mastic and mechanical fixings.
2. Apply the bead of mastic to the underside of the panel as outlined above.
3. Lay the panels into place. Note that chequer plate/ mild steel will generally not need to be pre drilled and plugs are not required.
4. Using a powered screwdriver hold the fixing true and slowly start the fixing turning. This will cut through the GRIPFAST® and start to cut into the metal.
5. Once swarf comes to the surface, increase the drill speed until the fixing is tight and securely holds the panel in place.
6. Repeat as necessary until the whole panel is firm with no movement.
7. Should access be possible underneath knock off protruding studs from the underside of the substrate.

Recommended fixings are as follows:

STAINLESS STEEL
1. Stainless Self tapper supplied standard size of No10 x 1.25” (other sizes are available but may be subject to special price and delivery.)
2. Stainless Steel Tek Screw. These are supplied 5mm x 40mm. For instructions on use please refer to section on Self Drilling Fixings.
3. Aluminium rivet. The size of our standard rivets is 4.8 X 18mm. (Please note: not suitable in the food industry as the hole in the top constitutes a bug trap.)

CARBON STEEL
1. Use fixings for stainless steel and also the cfl 32 tek screw.
2. Should security be an issue then a torx headed tek can be supplied.
3. Please note the 32 tek screw has been salt water spray tested to 700 hours but will rust in wet conditions and is not acceptable in the food industry.

FIXING DETAILS
SELF TAPPERS / RIVETS
1. Pre drill the Gripfast® with a masonry bit to the size needed. (ordinarily 4.5 – 5mm)
2. using a hss or similar drill bit (cobalt is very good ) drill through the steel. Cutting oil can be used to prolong the life of the bit but this would need to be approved by the client.
3. Fit the fixing in the appropriate manner.
4. As with all mechanical fixings once they have been fitted they need to be checked that they are secure.

IF FIXING TO OPEN GRATING :
1. If fixing to open grating we recommend the use of 'U' Clamps and integral locking nut.
2. Use approximately 10 clamps per square metre of Gripfast.
3 It is important to make a template for the hole centres so that they match the grating pattern and also miss the structural sections on the grating.
4. Pre-drill GRIPFAST® as previously described.
5. Insert bolt through hole and locate into “U” clamp and tighten then fit the nut to the thread below the clamp and tighten to secure the fixing.

1. Please note GRIPFAST® Heavy Duty DDA Compliant Treads are not load-bearing. They are not designed to be unsupported. If left unsupported they will break.
2. The tread is designed to be both bonded and mechanically fixed (See drawing.).
3. When fitting the tread it is important to ensure that it is pushed tight against the leading edge of the step.
4. Under no circumstances should the tread be allowed to overhang the leading edge.
6. Ensure sufficient mastic is placed underneath the tread to bed the tread down and minimise tread movement.
7. If required seal all edges with MS Polymer Mastic
8. When applying mechanical fixings, ensure that the tread is also fixed through the colour contrasting nosing. (See drawing.)
9. If it is not possible to fix through the front nosing, contact Polydeck Limited for advice.
10. Please note that failure to fix through the front nosing may cause the tread nosing to move excessively and ultimately come apart.

FIXING 2MM NAIL DOWN PRODUCT
1. 2mm Nail Down is designed to be fitted to a reasonably flat, good quality flooring and sealed concrete. It should not be used to cover chequerplate or heavily contaminated floors.
2. The product is designed to be bonded and then mechanically fixed with either nails or dome headed screws. The use of countersunk stainless steel screws or cfl fixings is not appropriate.
3. Fixing 2mm Nail Down in areas of direct sunlight should be avoided as too much movement can occur. If in doubt about your application, please contact Polydeck Limited.

USING TWO PART ADHESIVE TO FIT TACTILES
1. For large areas and a stronger bond a two part epoxy adhesive can be used. This is sold in a 5kg kit and will cover approximately 2 square metres per kit.
2. Before use, please ensure adequate preparation is completed. Ensure the area is clean and dry and free from dust or grease.
3. Mark out the area where tactiles are to be applied with masking tape or similar.
4. Decant Part A into Part B, thoroughly mix with a mixing drill for two minutes until both parts are uniformly mixed and a uniform colour is achieved.
5. Apply the adhesive to the floor with a notched trowel.
6. Peel off the backing from the tactile and apply the tactile to the floor. Ensure all air is expelled when laying the tactile to ensure complete contact with the glue.
7. Weight the tactiles down (with a heavy weight) and leave to cure for approximately 6 - 12 hours depending on external temperature.

EDGE SEALING
1. When fitting into the Food and Beverage Industry all edges will need to be sealed with approved sealant to avoid ingress of contaminants and to eliminate bug traps.
2. Both the GRIPFAST® and the substrate will need to be dry and free of grease and remain so whilst curing takes place.
3. Curing times are affected by temperature. As a rough guide: working time 5 – 10 minutes, cure time 24 hours (2 – 3 mm bead. )

MASKING
1. Areas adjacent to the joint should be masked with tape to prevent contamination of substrate and ensure a neat sealant line.
2. Masking tape should be removed immediately after tooling.

PRIMING
1. No primer is required on most non – porous surfaces, including vitreous enamel, ceramics and glazed tiles.
2. For some metals primers are required. Please refer to Gripfast® Technical department or refer to Data Sheet.

FINISHING
1. The joint should be “tooled” within 5 minutes of application to ensure good contact between the product and substrate.
2. Tooling of the sealant also gives a smooth, professional finish.

CLEAN UP
1. Excess sealant may be cleaned off tools and non porous surfaces whilst in an uncured state using silicon cleaner.
2. Cured sealant may be removed with the aid of silicon remover, abrasion or other mechanical means. Care should be taken not to cause damage to surrounding surfaces.
