Hi, we are looking for a paint to use internally (white) finish for a grade II listed building. Can you recommend an economical product to give a good level of breathability?
Assuming the walls are lime based or plaster, they are clean, dry, sound and prepared as detailed in the technical data sheet you could consider Graphenstone Ambient Primer L42 followed by Graphenstone GCS Interior.
This is available in a range of colours and Graphenstone Samples are available.
