Crown Trade Alkali Resisting Sealer is ideal for priming and sealing new, dry alkaline surfaces such as new lime plaster, concrete and cement. Suitable for interior and exterior use.
It can be used to seal stains such as water and nicotine due to its excellent stain blocking properties and can also be used for stabilising powdery chalky surfaces and promoting adhesion to glass, ceramics and some hard plastics and PVC-u.
