Application Method

Component A and B is mixed under low speed mixer until homogenous mixture obtained. Mixture must be used within 30 minutes. Otherwise gelling occurs and it cannot be recovered. PUB 401 must be used only on horizontal joints. The application surface should be protected from water minimum 6 - 8 hours.
