Explanation/Annotation:For priming of concrete surfaces before coating the water-proof mastic and hermetics.
Detailed model description:The prime coating use ensures the increase of cohesive strength of bituminous-polymeric compositions with machined surfaces.
specifications to a surface:
- the machined surfaces should be dry and clean;
- the concrete moisture shall amount to not more 4 percents;
- the surface temperature shall out-top the minus 10 degree. With;
- at negative temperatures advisible to heat weldfaces by the gas or infra-red burner system for disposal of possible ice hamp or frost.
the prime coating coating:
before its application one should carefully to displace. To rule the prime coating on weldface one should with the help of brush or sprayer with system of airless spraying. After prime coating drying (not more 40 minutes) proceed to pouring the mastic or hermetics.
requirement for safety:
in the composition of bituminous-polymeric prime coating are included inflammable. Is forbidden to carry out priming works near naked light and conducting places of welding. In case of execution of work is forbidden to smoke. The prime coating is to be stored in densely closed container, away from heat sources.
the average consumption of prime coating "of Izhora" 100-200 ã/ì^2.
the technical characteristics makes up:
1. Funnel viscosity, sec. 5-10
2. Mass fraction of low-volatile matters, ïðîö. no less than. 25
3. Drying time to the extent 3, minute. not more. 40
4. Film adhesion, severity, not more. 1 |
