Jesmonite Flexiguard Sealer is based on nano-technology and is a stain-resistant, invisible sealer
which creates a clear, UV-stable, and extremely durable surface for all Jesmonite composites
when used externally. Flexiguard is unique in that it creates a low-energy surface that prevents
soiling, and mould and fungal growth. This product, once applied, significantly reduces the need for
cleaning and maintenance and is effectively permanent due to the chemical bond made with the
Jesmonite substrate (subject to abrasion). It can be applied very easily almost anywhere – on site or
in a manufacturing environment.

We recommend that Flexiguard Sealer is spray applied as a mist coat onto the surfaces of AC730,
AC830 and AC930. It is important to ensure that all surfaces are clean, dry, and free from any
grease or oil.
The existing surface quality is preserved, becoming highly water and grease repellent, and resistant
to ingrained soiling, mould, fungal growth.
Contaminates are unable to adhere to the surface.
Cleaning becomes much easier and less frequent – typically requires 50-70% less often – and
withstands high-pressure cleaning (up to 50-60 Bar).
The lifespan of the substrate is extended because of reduced cleaning cycles.
The surface remains clean and will not discolour.
Available in 1kg and 5kg canisters.
Keep receptacles in a well-ventilated area. Keep receptacles securely closed and protect
