Repainting painted bricks in enclosed formerly external porch
Posted: Wed Sep 23, 2020 2:30 pm
Hi,
We have a ~1900 built house which had an external porch area- quarry tiles and brick which has latterly been turned into an inside porch with a uPVC door.
The bricks in the porch have been painted magnolia with what we suspect (but don't know) is a vinyl emulsion. The paint has bubbled ins some places presumably due to damp/ salts/ efflorescence.
The bricks have signs of a chemical damp proof course being injected too.
I want to repaint the bricks white but am keen to do this in a way which is breathable and lets any further moisture escape rather than trapping it in the wall where it might pass into the plastered hallway.
I have been trying to research different paints which are breathable but some designed for painting brick need to bond with the brick which isn't possible here as it's already painted.
Would be really grateful for thoughts on what to paint with and how to prepare area where paint has bubbled.
Thanks.
