Substrate Preparation

Remove all residues of existing sealing material. Clean glass surfaces very thoroughly.

Derust and clean steel surfaces, then apply two priming coats of Capalac AllGrund.  

Method of Application

Fill the joint with Capadur Repair FK (avoiding blistering) and smoothen with a joint scraper, suitable for sealing glass.
Use suitable adhesive tape in the border area before filling joints to obtain a sharp and linear edge. Remove the tape directly after smoothing. Do not use smoothing agents such as soapy water.

Surface Coating System

Cured Capadur Repair FK can be primed with Capalac Allgrund or Capacryl Haftprimer. The surface can be painted, when the priming coat is thoroughly dry.

Priming coat: Capalac AllGrund. 
Finishing coat: Capalac Venti or Capalac BaseTop.

Priming coat: Capacyl Haftprimer.
Finishing coat: Capacryl PU-Satin/Gloss or Capalac Aqua PU-Alkyd Satin/Gloss

Note: Always prime the full casements in order to avoid wetting failures.
