Painting lime plaster internally

292 viewsBreathable Paints

We have a house with lime plaster internally and a Dulux vinyl Matt undercoat has been put on. Dulux have said it is breathable with an SD of < 0.03. Should this be acceptable or is it impossible to have vinyl breathable paint with a low SD? We are considering trying to take it off. Thank you, Michelle.

Dear Michelle

I would be quite surprised if a vinyl matt had such a low SD value, especially as low as 0.03. Have they provided any documentation to state this? Also it is worth checking that if the SD value is just for the undercoat or is it for the paint itself?

An SD value of 0.03 would be suitable for a lime plaster
