The Paint Shed recommends

A great primer for bare plaster and as a sealer on chalky surfaces, it provides excellent resistance to alkali attack.

Johnstone's Trade Alkali Resisting Primer is a solvent-based primer and sealer for interior and exterior use on new or bare plaster, concrete, cement, render, or wood and metal surfaces. It is suitable for interior and exterior use, and provides exceptional resistance to alkali attack when used as a primer on unpainted surfaces, or as a sealer on powdery substrates. 

Applying Johnstone's Trade Alkali Resisting Primer

For best results, apply using a brush or roller to a clean, dry surface. Stir well before use and always ventilate the area being painted.

Customer Questions
Can I use this primer on exterior wood ?
Yes, The Johnstone's Trade Alkali Resisting Primer can be used on Exterior surfaces.
Would a standard emulsion take on top of this primer? I have had trouble in the past using an acrylic primer rejecting the top coat
Most Oil based paints can be applied.
Can this be used on solid oak architrave in our hallway?
No, The Johnstone's Trade Alkali Resisting Primer can not be applied.
Does this contain shellac ?
No, The Johnstone's Trade Alkali Resisting Primer does not contain Shellac
Can this primer be used over existing oil based high gloss and the painted over with a water based paint
No, Johnstone's Trade Alkali Resisting Primer provides exceptional resistance when used on unpainted surfaces or as a sealer on powdery substrates. We would advise using Zinsser Bullseye 123 Primer to use on top of glossy surfaces and a water-based paint can also be used on top of this product.
