HANDLING INSTRUCTIONS
Sealant components are mixed just before use by hand mixing or spiral drill (in order not to create extra air bubbles speed of drill should be not more than 300 rev/min) till getting homogeneous paste, but not more than 5 minutes. Quality of sealant depends on mixing accuracy. Partial mixing is not recommended, as there is possibility of wrong measurement of components.
Mixing with solvents is strictly prohibited, as it leads to loss of thixotropy and other properties, cause shrinking and cracks.
Sealant layer should be not more than 3-4 mm.
Viscosity of sealant components increase under low temperatures. Mixing and storage is recommended in heated buildings.
