Application steps

SUBSTRATE PREPARATION

The substrate must be clean, dry, sound and free from oils, grease, dust, cement laitance and loose or friable particles.

Note: Primers and activators are adhesion promoters and not an alternative to improve poor preparation or cleaning of the joint surface. Primers also improve the long term adhesion performance of the sealed joint.

APPLICATION

Apply a single coat to the prepared substrate using either a clean brush or roller. Tightly re-seal container immediately after each use.

Use within 1 month after opening the container. Discard any primer that has gelled or separated.

 

CLEANING OF TOOLS

Clean all tools and application equipment immediately after use. Hardened material can only be removed mechanically.
