The joint surface must be thoroughly dry, clean and frost free. Remove all dirt, laitance, loose materials and foreign matter from the joint faces. Remove all rust, scale and protective lacquers from metal surfaces. Remove all round or sharp edges and corners. The surface should be degreased using SOLVENTE 10.
A thorough wire brushing, grinding or sandblasting may be required to expose a clean and sound substrate.
Ensure that the substrate is absolutely dry before the primer is applied.
SEALPRIME NP should be stirred thoroughly before application.
SEALPRIME NP shall be applied to the joint faces prior to the installation of backer rod or bond breaking tape. Apply using clean, dust-free cloth or brush in a thin uniform coat. Avoid excessive application on ponding of the primer. Allow the primer to dry for a minimum of 10 minutes Re-priming is required it the sealant application gets delayed by more than 3 hours after application of the primer.
When applying the sealant, ensure adequate tooling force, so that the sealant comes in good contact with the primer.
For obtaining a clean and neat finish, masking tape should be applied on both the edges of the groove before applying the primer and shall be removed after the sealant installation is complete.
Tools used should be cleaned with SOLVENTE 10 immediately after use. Hardened material should be removed mechanically.
