Fillcoat Fibres

The Fillcoat Fibres system is designed to be instantly waterproof, have 1300% elasticity and to provide excellent resistance against weather and mineral acids. It is not resistant to solvents and alkaline substrates. It does not contain bituminous products and has excellent adhesion on different substrates.


Remove dust, mud, grease, moss and leaves carefully. Areas to be repaired are cleaned with a hard broom and sponged. In case of repeatedly repaired areas, major or active cracks, apply Fillcoat Fibres crosswise over the cracks or fissures. After cleaning, Fillcoat can be applied directly on bituminous substrates, hard PVC, polyester, zinc, aluminium, glass, tiles.
