Definitions
- the present invention relates to a frictional surface product, a method for applying a frictional surface to a rideable board, a kit, and a rideable board.
- skateboards It will be convenient to describe the invention in relation to skateboards. However, it will be appreciated that the invention is suitable for use with other rideable recreational boards or devices such as scooters, surfboards, snowboards, sandboards, wakeboards, wakeskates and the like.
- skaters usually have to completely remove the existing grip material and apply a new sheet of grip material to the deck of the skateboard, which can be a difficult task, or buy a new skateboard.
- skateboard grip materials are comprised of a polymer film (for example polyester) with a layer of abrasive aggregate material (for example, crushed glass, silicon carbide or aluminium oxide) suspended in a hardened adhesive compound (for example, epoxy). It is very similar to the texture of sandpaper.
- the sheet of material has a film of paper-backed adhesive underneath. The skater removes the paper backing and applies the grip material to their skateboard deck. The skater then uses a knife to trim away excess material around the edge of the deck.
- some skateboard manufacturers are applying the aggregate material and hardened adhesive compound directly to the deck of the skateboard as part of the skateboard manufacturing process (and thus avoiding the polymer film layer, and the need for the skater to install the grip themselves).
- skaters prefer grip material with a high coefficient of friction, whereas other skaters prefer lower coefficient of friction. This depends on their skating style. Currently, there are only limited products that allow skaters to customise the level of friction when installing a new grip material.
- skateboards which are substantially longer (i.e. between 1 to 2 metres) than normal conventional skateboards, typically referred to as longboards.
- longboards provide a significant amount of flex in the deck which particular riders find appealing.
- the applied grip tape actually separates from the deck during the flexing motion, which can lead to tearing of the grip tape.

- the liquid adhesive 18 can have the aggregate 19 mixed in by the installer during application using the stirring stick 21, or it may be provided in a premixed form 17.
- the installer may distribute the aggregate over the deck of the board 4 which has the wet coat of liquid adhesive 18 already applied. The installer may distribute the aggregate evenly. Alternatively, areas of the deck which require more or less friction for the rider may receive more of less aggregate material from the installer. Additionally, different sized aggregate material may be used for different sections of the board to provide varying coefficients of friction over the deck.
- the overhanging edges of the installed fabric 3 may be frayed by the installer using a pick 23 as illustrated in Figure 19.
- the frayed overhanging edges 1900 can provide protection to the edges of the skateboard 1 when the rider performs manoeuvres where the edge of the deck may come into contact with the ground surface.

- the method includes the installer using the pointed end of the skewer 22 to form holes 5 in the installed fabric 3 to allow the screws 9 to pass through the installed fabric 3.
- the installer may not be required to provide any additional frictional surface to the fabric in the event that the rider is satisfied that the fabric provides a sufficient amount of friction for their particular requirements. This may particularly be the case in the instance that the user wishes to utilise the board for barefoot riding.
- the method proceeds to step 1495.
- the method can continue onwards to step 1480.
- the method includes the installer applying a liquid adhesive and aggregate material to the upper surface of the installed fabric.
- the liquid adhesive may be applied, then subsequently the aggregate material may be applied to the adhesive whilst wet.

- the installer may then apply multiple coats of adhesive 18 to further capture the aggregate within the applied adhesive 2.
- the liquid adhesive and aggregate may be provided in a premixed form, wherein the mixture is applied in a single step to the upper surface of the fabric.
- the stirring stick 21 may be used to stir the mixture to create an even distribution of aggregate material throughout the mixture prior to application to the fabric.
- the aggregate and liquid adhesive may be provided separately, wherein the installer can customise the amount of aggregate to mix with the liquid adhesive such that the mixture is applied to the upper surface of the fabric.
- the installer can use a stirring stick 21 to mix the preferred ratio of aggregate material within the liquid adhesive based on the required level of friction.
- Step 1480 may be repeated a plurality of times if required depending on the desired level of friction that is required.
- the method optionally includes the installer trimming back the edge 12 of the installed fabric 3.
- the installer may trim it back in line with the edge 24 or the radius 14.
- the installer may trim the installed fabric 3 back such that the edge 12 of the installed fabric 3 extends beyond the edge 24 of the skateboard 1.

- the installer can use the pick 23 to unweave the edge of installed fabric 3 between 12 and 13.
- the method includes the installer installing the screws 9 that secure the trucks 10 and wheels 8 to the skateboard deck 4. This step is generally performed once the liquid adhesive has dried. The installation is complete.
