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: for interior and exterior use. This is the recommended sealer before applying MUROBOND Cement Paint. It can also be used to seal and bind old lime paints, 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.
