Tac-Pads must be applied to a level surface. Surfaces must be dry, clean and free from dust, oil and fuel spillage. Premark Primer is required for concrete, stone and worn macadam surfaces.

Clean application area thoroughly by removing all sand, dirt, chemicals and oily substances.

Remove all moisture present (if any) in the surface with a gas burner.


Position both adhesive and Tac-Pad layers in a position ensuring that the beaded side of the Tac- Pad sheet is uppermost and that the individual pieces are positioned correctly and with no gaps in-between. Sheets may be cut to shape using tinsnips or a stanley knife if required.

Remove the Tac-Pad layer and heat the adhesive layer using a powerful gas burner (pressure min. 3 bar). Move the flame slowly but steadily 10 to 30 cm over the material in a sweeping motion so that heat is evenly applied. The material must be heated until all the material is liquid (approx. 200°C). Immediately after heating place the Tac-Pad on top of the adhesive layer with the beaded top coat facing up.

Applying insufficient heat will result in inadequate bonding and failure. If overheated, superficial scorching of the material can occur resulting in brown blotching, but this discolouring will soon disappear once the marking is exposed to traffic and weather.

For application on non-bituminous surface (e.g. concrete) follow the same steps as above but in addition, apply Premark Primer (sealer) to the entire surface area where the Tac-Pads are to be installed. Allow the primer to dry until it is no longer sticky before applying the Tac-Pads.

Follow steps in the first paragraph above.

Apply Premark Primer (sealer) on to the entire surface area where the marking is to be installed. Allow the primer to dry until it is no longer sticky.

The more porous the surface, the more primer is required.


Both the Tac-Pad and the adhesive layer are 400mm x 400mm.
