Brick is porous, so even painted brickwork can absorb rainwater and let it seep into your home.
When gyprock sits against damp brick around a window opening, it can draw in moisture and start growing mould or breaking down. That’s why we coat every window opening with a two-part epoxy primer before the gyprock goes on, locking moisture out of the brick for good.
It’s a small step that new building codes now call for, and on renovations like this one, it’s well worth doing even when the windows stay put.
