Application Procedure



Preparation of Substrate


The surface must be dry and clean before application. All joints before filling shall be carefully cleaned by metal brushing or sanding. The dust should be removed by pressured air. PUK 401 causes foaming when applied on moist surfaces. Therefore the joints must be dry and the sealant must not contact water until chemical curing occurs.


Application Method


Component A and B is mixed under low speed mixer until homogenous mixture obtained. Mixture must be used within 30-45 minutes. Otherwise gelling occurs and it cannot be recovered.



Consumption



1,25 kg/lt



Packaging



A component + B component = 5 kg set



Shelf Life



12 months in original, unopened package.



Storage



Store in dry area between +5°C and +35°C. Protect from heat, freezing and direct sunlight.



Cleanup Information



Clean tools and equipment with industrial type solvents immediately after use. Dried material can only be removed mechanically.
