Application

Ensure that surfaces to be sealed are clean, dry and grease free.

In order to reduce the deformations of the joints, their depth must be much less than their width, minimum dimensions are 5x5 mm, for wider joints the depth should be preferably half of the width and it is adjusted by the use of a backup material.

After the application, the sealant must be tooled with light pressure within 5 minutes to spread the material against the joint surfaces and to obtain a professional finish.

Excess uncured sealant may be cleaned with solvent. Cured sealant can be removed barely mechanically.
