I'm tired of the bubbling/peeling paint all over the front concrete porch. It's time to take care of this. I'm looking at Home Depot's BEHR Concrete and Masonry Paint Stripper. Any thought on this product or others? It sounds like I'll need a good pole scraper and wire brush, as well as possibly a pressure washer to finish things up. Any experience with this job or any opinions at all? Thanks!
