INSTRUCTIONS
Ensure that surfaces to be sealed are clean, dry and grease free.
The application temperature must be between +5°C and +40°C.
In order to reduce the deformations of the joints, their depth must be
much less than their width, minimum dimensions are 5×5 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.
6 mm. joint depth is recommended for joint widths between 6 mm to 12 mm.
Joint width and depth ratio should be about 2:1.
