IP has several brown ring stains on ceiling in two bedrooms. Looks like some major leaking in the past and mould.
I have just finished painting the house. Thoroughly cleaned ceiling. I Painted over them with Zinssar stain blocker oil based. Then two coats of ceiling paint. A week later the brown rings have come through and look worse or are more obvious than before.
Are there other products I can use to stop the stain penetrating?
