HOW TO PROPERLY PAINT AN EXTERIOR WALL.
| Pick the right paint. It's hard to find masonry paint in bright colours, though they are starting to become more popular (this trend is only going to grow). Try designerpaint.com for a good selection of colours. | Fix any problems before you begin. Remove any chipping paint with a scraper or a stiff bristle (not wire) brush, and fill any cracks and gaps with a masonry filler. Allow at least 24 hours for the filler to dry and sand it down for a smooth finish.
| Prepare your surface for the best results. Paint over patches of green or grey growth with a fungicidal wash and allow 24 hours to kill the fungi. Paint over flakey or chalky surfaces with a stabilising solution - it's like a sticky primer that creates a better surface to paint over.
