I'm looking for advice today.
My project for the next few weeks is to refinish the railing to our deck. In past years, we've sanded and scraped flaking paint on the railing and repainted over it. Living where it's so wet most of the year, paint doesn't hold up well for us.
So, we're going to sand all of the paint off the horizontal surfaces of the railings and use outdoor stain and seal instead of paint. For me, this means I have to sand off every bit of paint, years and years of layers of paint from the top rail and bottom rail. I'll use a grey solid stain (most coverage for a stain) on horizontal surfaces. The stain will need refreshing every year. However, reapplying stain is a lot easier than sanding/scraping and repainting.
Being vertical so water sheds easily, the balusters and support posts for the railing seem to hold the paint well. So, I'll paint all of the vertical surfaces, instead of stripping and staining those parts. I'll use a black paint on vertical surfaces. I'll need to repaint these parts every 5 years or so.
For this project I bought a disk sander designed for stripping paint. It works pretty well, but this is still an involved process. I've worked 2 days so far and have removed the paint from the majority of about half of the top railing. I should have the majority of the entire top rail done by the end of the weekend. I'll still need to go in with scrapers and sand paper to get the bits that are close to the upright posts where the sander couldn't reach. I'll also need to sand and scrape the bottom rail by hand, as the balusters are too close together for the sander.
My questions -- has anybody here ever refinished a deck railing? Have you stripped outdoor paint from wood surfaces? If so, did you sand it off or use chemicals? Do you have any tips for scraping/sanding paint in tight areas? Have you used any special tools for sanding or scraping? Thank you for any advice you can offer.
