What is it?
Colspray is a bitumen cold joint sealer & tack coat spray that is applied onto vertical edges and the surface base before the application of asphalt. It will increase the bond of the material to the substrate and waterproof the area. This will significantly enhance the reinstatement’s performance by preventing the ingress of water and freeze/thaw effect.
Where to use?
- Transverse or longitudinal vertical joints
- Patch repairs
- Trench reinstatements
- Drain or manhole frames
- Kerb channels
Colspray is supplied in 750ml spray cans, with the bitumen being discharged by inverting the container and pressing the spray button.
Remove as much standing water and loose particles as possible prior to product application. The sealer can be applied to damp or dry surfaces.
Hold the can tightly and shake vigorously before use. Invert the can and press the spray button. Cover the area to be sealed with long strokes from a distance of 175mm to 250mm, working from the top downwards. Ensure that the entire surface is covered.
Point nozzle upward immediately after use and spray for a few seconds to clear it, taking care not to spray into wind. Failure to clean the nozzle after use could result in the aerosol becoming blocked rendering the product unusable.
Aerosol cans must NOT be exposed to direct sunlight or temperatures above 50°C. Store in a cool well-ventilated place.
