i am looking to paint a hall, stairs and landing previously done with Venetian plaster. Could you please advise on a suitable product to use as a primer so ordinary emulsion can be applied afterwards. Thanks
Assuming the venetian plaster is absorbant, clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Keim Optil for a paint finish.
This is available in a range of colours in a matt finish.
