Preparation

Thoroughly clean surfaces and allow to dry.

All loose and flaking material must be removed from the areas to be treated, surface rust may remain in-situ.

If existing finishes are delaminating throughout the roof area, all existing factory finish must be removed in a straight line, across the area to be treated, creating a defined line between the existing finish and the cut edge corrosion treatment.

Suitable preparation methods include but are not limited to: wire brush, grinders and Quill Falcon Kwikblast system.

Surfaces must be completely dry prior to application of the Flexlap silicone component. If an existing cut edge corrosion system is present, consult manufacturer before proceeding.
