Hot-applied Sealing Compound

Sealing compound for filling seams and joints

Application:

Filling of expansion joints and connections in all types of traffic-loaded pavements
Filling of horizontal or slightly sloping joints with a permissible gradient of up to 8%
Sealing of joints between pavement (concrete, asphalt) and precast, steel elements
Filling and sealing of cracks and damaged seams in asphalt pavements

The temperature of the substrate and air during the works should be from +5°C to +30°C.
Works should not be carried out during precipitation and strong sunlight.
Hot-applied Sealing Compound should be pre-crushed and then heated in a boiler equipped with a thermometer and thermostat to 140 - 150°C in order to obtain a liquid consistency. The mixture should be stirred when heated to prevent local overheating and the deposition of coked sealant compound on the walls of the boiler. In order to obtain the required properties, the temperature must not exceed 180°C. For the same reason, the mixture should not be subjected to repeated heating. It is advisable to heat only the amount anticipated for a full day's demand.
After application of the Hot-applied Sealing Compound check if the product adheres to the walls and if it properly bonds to the previously prepared substrate. The detachment of the product from the covered surface should also be inspected. The product must not be poured lower than the pavement and it is therefore required to check that it has been applied at the correct height. The difference in height weakens/reduces the adhesion of the product.
