Window Scraping and Repair

Some of our time this past week has been focused on removing the roof, adding a temporary covering with a tarp. The insulation and roofing sub contractors will be visiting Mark next week, so our job was to get everything prepped for them (video coming soon). Aside from that, we scraped the paint off the two rear kitchen windows, sanded them, applied a base coat of shellac to seal the wood (until the application of varnish), and re-roped the window sashes. As with most jobs, having the right tools really makes a difference. Mark has a nice collection of scraping implements, each with a unique sharp edge to them. His primary scrapers are tools he makes himself that offer swiveling heads to get into hard-to reach corners. He also has two types of improvised jigs that allow him to scrape and plane the window sashes easily and quickly. There are several strategies for exposing the bare wood, and each situation merits a different approach. Mark experiments to find which works best. For example, these windows we stripped in the kitchen had a layer of shellac and then paint on top. There had been some pretty heavy water damage in that area, which made scraping the windows fairly easy and fast. Had that not been the case, it may have been more efficient to use a heat gun and/or chemical stripper. The upside of those two approaches is that you avoid having to do much, if any, touch-up sanding before applying a new coat of shellac (sealer). The downside is that they can be messier, and in the end, more time consuming. To strip, sand, and shellac took around a day for each painted unit, meaning the sashes and casework. Check back soon for a video documenting the window-stripping process!

    What kind of mask do you use?

      I use a 3M 6300 series face harness. The Filters are also by 3M. I’ve used many varieties of filters and find these to be great, there’s a greater upfront purchase price but they last a long time hence cost effective. The pink filters restrict 100% of the dust particulate and the mask’s seal to the face is wonderful if fitted right. Many paint stores carry the mask, the filters are a bit trickier, an automotive paint supply store around the corner from me carries them.
