ThermaBandPlus is an overbanding product made from preformed thermoplastic, which is used to seal joints in asphalt surfaces, preventing water ingress & associated frost damage. It has an advanced Plus formulation which retains flexibility even in cooler conditions and has an anti-skid treatment impregnated into the surface.It is easily laid, durable, and meets Highway standards, without the need for boilers and associated hot-work risks. The advanced Plus formulation overcomes a major drawback with other brands and enables work to continue through winter months.

Features and Benefits:
- Use of overbanding prevents frost damage due to water ingress through joints
- Advanced Plus formula retains flexibility in cooler conditions
- Economic way of overbanding
- No specialist boilers or complicated equipment required
- Has anti-skid grain already impregnated - no broadcasting required
- Can be trafficked very quickly, to minimise road closure times
The application surface should be sound and clean, free from grease, oil, rust, scale, dirt, or any other soiling that might affect adhesion or performance. In any case, but especially in the case of overcoating existing line markings, it is further recommended that test areas be coated to ensure good adhesion and/or compatibility with the substrate.
Asphalt – weathered - It is recommended that asphalt and other similar surfaces be allowed to through harden for up to 6 months before painting. Test trials should be carried out in the first instance on a small area.
Concrete & other cementitious surfaces – ThermaBand is not recommended for use on concrete surfaces
Asphalt & tarmacadam - no primer required on weathered surfaces; ProTack aerosol primer or BituSeal edge sealer may be used to improve adhesion if desired
Product supplied ready to use, straight from the box
Pre-mark to show where product will be installed. Lay out product and cut to size, by scoring with sharp knife & gently bending back on itself to "snap" clean. Put product to one side
Use gas torch to pre-heat surface where product is to be laid, to remove any moisture and provide a warm surface to enable bonding.
Place the product in position and use gas torch to heat. Go over the marking in a pendulum motion, holding the torch no closer than 150mm to the product. Avoid holding the torch in one place, as it will cause the product to scorch.
You will notice the product beginning to shrink/melt into the profiles of the surface. The edges will also ‘bevel off’ as it melts. Apply heat until the whole area is fully bonded to the surface.
Do not apply when the air or surface temperature is below 5°C or less than 3°C above dew point, or if this is likely to occur during the curing period.
Do not apply when there is rain, mist, fog, or snow imminent; when humidity is high or the surface is wet with condensation or likely to be during the drying period.
The product should not be trafficked until it has cooled to the temperature of the surface it is laid on. If required, cold water can be used to cool the product
