I have some old stairs I'm trying to scrape off. The paint is basically just sitting on top of the wood but it's hard to scrap it off because it's weathered and not a very flat surface. I was thinking to use some stripping agent but the paint will still get pressed into the creases when scraping off. So I thought to then use power washer but that would be setting all sorts of lead into the ground even if used tarp underneath going to run off. Don't want to poison the groundwater... What's the best solution?
Power washer probably overkill.
Stripping agent, scrape off, some more stripping agent and a soft wash/wipe should do it. Some stripping agents can be as bad or worst than lead paint for your health.
Use protective gear. Depending on the locals, might need to have professional lead removers do the job, you might not be allowed to do it yourself.
Just need to remove the loose paint, not all of it, then paint over to cover. Think there are paints made for covering lead paint, do not know if any exterior paints for this.
