I'm palm sanding (quarter sheet) flaking/chipped paint from exterior hardwood siding I want to preserve. I read some hints here, but I'm seeking any other labor-saving hints - this job is tedious. Here's the best of my knowledge so far:
- First scrape loose material with a good 5-in-1 tool - avoids gummed paint in paper.
- Separate sanding/painting teams - paint teams need clean air & surface.
- Pre-drill a big stack of sheets with vent holes - avoid manually punching holes with each paper change.
- Change paper often - gummed paper works much worse than new, and new paper is probably cheaper than your time. Is paint stripping sandpaper definitely an advantage over general purpose sandpaper? They don't sell it at my local big box stores.
- Use good breather, snug gloves, safety glasses, and ear protection - have good knee pads handy for low work - throw in some earphones & music, this is a long job.
- Spot prime after rough sand - use finer grit for resanding before later coats.
- Use the best quality paint you can afford - you don't want to do this job again soon. Modern oil based primers will accept latex paint.
