Using a gas torch, it is important to pre-heat surface where the product is to be laid to remove any moisture and provide a warm surface to enable bonding. Please read product data sheet to ensure you are familiar with the effects of surface heating and moisture
Place the marking in position and use the gas torch to heat. Move the torch side-to-side over the marking, holding upright and no closer than 150mm. Avoid holding the torch in one place, as this will cause the thermoplastic to scorch.
