IMPORTANT

On rough substrates, use a brush to apply primer and make sure the primer covers all the surface, including voids.

Note: To prevent air bubbles affecting the finish, do not 'over' brush or roll it.

Apply Sikagard®-850 Primer evenly over the prepared coating with a brush or long hair roller at the required consumption rate.

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