Surface preparation

Position warning signs and cones if necessary and ensure all vehicles are removed from the working area. The surface of the road must be dry and clean. If there is any surface water, sweep this away and dry out dampness with a torch. If the ground in cold, heat with the blowtorch before laying the markings. This will aid adhesion to the surface of the road. 


If appearance is critical we recommend the application of a small trial area first.  

Remove the protective plastic film and place it into position. When laying lines, ensure they are ‘butted’ up correctly and straight. Set regulator at 25psi, ignite and turn torch on to required pressure. Position nozzle of blowtorch 4-6 inches above the centre of the marking at one end. With a ‘pendulum’ motion from side to side, bring the material to a fluid state so that the marking bubbles and then proceed down the marking using the same action. Care must be taken in the speed of the bonding. Too slow and the marking may burn, too fast and the marking may not bond. If the flame is too high and incorrectly angled, it is possible to distort the markings. Good application can be achieved with experience. If the marking is multi-layered apply base layer first and allow to cool. Then position the second layer and repeat the fixing instructions. Allow material to cool before removing cones. If fast cooling is required, it is suggested that water may be sprayed over the markings.
