Few home-maintenance projects are as important as exterior painting because paint and caulking form the first line of defense against rain, heat, and cold weather. Also, a new coat of exterior paint can make a huge difference in your home atmosphere and curb appeal.
You would want to repair and repaint as soon as you notice paint starting to crack, blister, and peel. Ignoring these problems will lead to a much more extensive and expensive job.
Before painting, all the problems will be resolved. Loose boards will be nailed down. Dirt, grime, and flaky paint will be removed by pressure washing and sometimes sanding of the wooded areas. Putty or caulk can be used to reseal all the small holes or dents created by nails, and elastomeric caulk can be used to seal minor hairlines on your stucco.
