I plan to use Sandtex masonry paint again as the last lot mostly stuck on for several years.
Rather than paint over the cracks I thought I'd scrape away a bit and discovered a couple of areas where the motar(?) between the bricks is very 'sandy' and falls out easily.
I don't know wether to use some kind of stabilising product, water down the masonry paint and soak it in before a top coat or re-point it first. All of which I am unfamiliar with so thought I'd ask here for a recommended approach before starting.
thanks for helping this old timer!
