MUROBOND Sealer & Binder is a specialised sealer for binding chalky, powdery or very porous masonry and alkali substrates. It forms an alkali resistant film that binds the surface and seals it ready for top-coats.
Suitable: this is the recommended sealer before applying MUROBOND Cement Paint. It can also be used to seal and bind old lime, cement, or chalky water-based paints which may otherwise cause adhesion failure. Can help consolidate flaking paint. It will not prevent tannin bleed or efflorescence.
