I have a project in which a member of the owner's team wants me to specify linseed oil-based paint for exterior wood trim on a building with some historic significance (1820s Ohio). The few sources I have found online so far are in Europe. A commercial paint representative I have worked with for a few years told me the paint is very expensive, has a long lead time, and may have prohibitively high VOC content. Any input from the 4specs group on cost and availability of this product would be welcome. Thank you. Dave Wyatt Ronald J.

You need better clients I don’t think linseed oil-based paint has been produced in the United States since the 1920s. But I guess that would be new technology for your building, and perhaps the building owner. It is not all that uncommon for painters today, to add 10 percent linseed oil to oil-based paint to improve flow. Linseed oil is sold at most of the box home improvement stores. Perhaps that would satisfy your client. However, few paint manufacturers would recommend an oil-based paint for exterior applications, considering the advancements in water-based paints. Good luck.

Especially on exterior where it can destroy the wood fibers from the lack of UV protection. David J.

It confirms the traces of information I have so far. Apart from that, I hope things are going well for you in Florida.

Any 19th Century painter know how to make paint. The process is shown at: https://www.youtube.com/watch?time_continue=425&v=-UxsAij-ykg. Send us pictures showing the progress.

Can understand why one might want to use it in a historic restoration, but an alternative may need to be found which remains true to the spirit of the restoration work, is compatible with existing substrates (probably includes previous paint layers), and offers better protection.

My guess is that tying into the exiting coating will be tricky at best and I question whether the owner will be comfortable stripping everything down to bare wood or if that's even advisable. Somehow I have to wonder if going to Home Depot for a can of Kilz primer is going to cut it for this work. Any chance of bringing in the big guns like KTA Tator in Pittsburgh, https://kta.com/, to weigh in on this?

Brian Powell and Melissa McGrew are two of their experts in painting and finishing. Their work is not exclusively in NE. Our National Park Service has an excellent resource in their Preservation Briefs, including several about exterior woodwork and painting. - Paul Sweet (Unregistered Guest) Unregistered guest Posted on Thursday, April 05, 2018 - 12:36 pm:    https://www.nps.gov/tps/how-to-preserve/briefs/10-paint-problems.htm
