Invisible Sealer is a non-film forming impregnating treatment. This advanced water based formula allows you to seal your paving immediately after installation and allows efflorescence/salts and moisture to pass from the mortar bed through the paving. This sealer is an environmentally friendly product, completely waterborne, non-toxic, solvent and silicone free.
Features and Benefits:
Delays the penetration of water and oily liquids, allowing time to clean up spillages to prevent staining of the hard landscaped areas.
Treated surface remains both air and water vapour permeable
Internal and external use
Always carry out a test first in an inconspicuous area to ensure the finished result is acceptable. One to three coats may be required depending on how porous your product is. Please refer to the Invisible Sealer Technical Guide for full usage and instructions.
