About Us


Surface Pro is a biodegradable and natural polymer-based liquid surface protection film that’s applied easily with an airless paint spray machine, preferably an AW-1 cleaner. It dries to create a flexible and peelable temporary protective layer.

It’s suitable for various porous and non-porous surfaces like bricks, bathroom shower trays, tubs, tiled floors, walls, and worktops, guarding them against damage during construction.

Just remove the biodegradable, recyclable plastic film within six months of application when the protection is no longer needed. Plus, it won’t leave any residue behind.
