Bottom wooden window sashes can become soggy and wet from condensation inside and lack of putty, paint etc outside and the wood will normally require replacement or serious surgery to restore them.
Outside, exposed wood such as fascia boards can take a severe beating from the elements resulting in a similar problem.
Here’s a simple way to save those sashes etc and prolong their life for decades.
Sand or scrape off any remaining paint or varnish. Using a paint brush, apply several coats of Owatrol oil to the wood over the course of a day until it takes no more, this action will drive out all remaining moisture inside the wood. Any sections that have deteriorated extensively can be gouged out with a chisel or even a screwdriver, and filled with an appropriate wood filler. When filler dries, sand as required. Apply undercoat with about 33% Owatrol Oil mixed in to get maximum penetration. Finish off with an oil based paint of your choice with about 15% Owatrol Oil added in for perfect flow and a brush mark free finish.
How to cure the annoying problem of paint peeling off from wooden windows, fascias, doors, etc.
Paint and varnish mainly peels off because of poor grip and penetration of initial coats applied. This can be made worse by moisture ingress where paint has lifted nearby and frost plays its part also.
THE FIX… Remove all the peeling paint using appropriate means, perhaps a sander, heat gun or even a paint stripper etc. The fix is a similar method to garden table, chairs and bench mentioned on page 5. Mix in at least 33% Owatrol Oil into your first coat of any oil based paint / varnish (can be oil based undercoat or even gloss). That ‘mixture’ will enable the new paint / varnish to soak into the wood providing ‘deep roots’ for your paint which will not peel off as before. A second coat of paint / varnish with less Owatrol Oil (about 15% or just enough to make the paint “flow” nicely) will give a great long lasting finish.
