How to Use

Surface Preparation

All surfaces must be clean and dry, free from dust and grease or, anything which may be detrimental to correct adhesion of the sealant. Residues of old sealant or other materials as well as mould on the substrate must be removed completely (if necessary, use a silicone remover). To get best sealing results it is recommended to mask off edges of the joint with masking tape before applying the sealant


Sealant application

The sealant should be applied ensuring that the seal is filled. Smoothing off the seal ensures good contact between the sealant and the bonding surfaces. Directly after application, smooth off with an UniBond Sealant Smoother Tool. Remove any tape immediately, before surface skin has formed on the sealant. Smooth over any proud sealant edges immediately.


Cleaning and finishing

Fresh sealant may be cleaned with a cloth soaked in white spirit or alcohol (e.g., methylated spirit) Cured sealant can be removed by scraping (e. g. using a razor blade) or by using a special silicone remover product. 


Drying time

The sealant will be touch dry in 20 mins and fully dry in approximately 24 hours.
