Help please! Stripping & restoring magnificent cedar fireplace, architraves and doors
Hello, I am looking for suggestions regarding the stripping and restoration of cedar timberwork in the bedroom of my 1850s homestead. There is a fireplace surround, 2 French doors, solid door, window, architraves and skirting boards. I have had a little experience in stripping paint from cedar in another room and finishing it with shellac. For some reason the shellac/varnish in this room is extremely crazed and thick. I am not sure why this has happened. I have started on the fireplace rubbing it back with steel wool and metho and lots of elbow grease. It is a big room so I was wondering if there are any easier methods to use, I am guessing the answer is probably no! All suggestions from the gurus of cedar and shellac gratefully accepted. Should I use a different technique/finish on say the skirting boards compared to the doors? Looking forward to your responses. Marion
Please follow the restorer's code - less is best
Hi,
I have restored a 3 storey sandstone ashlar heritage house in Tasmania (National Trust and National Estate listed) and won an award for what we did so I do have some experience. Please do not use Tung oil on a heritage fireplace. Wonderful though that may be in some circumstances, it is not appropriate for heritage conservation. Besides IMO a good shellac finish gives a better view into the beauty of the timber (except outdoors of course where the weather destroys it).
I agree with others here that the lovely old crackle finish was the best, and very beautiful in its own right. After all, why try to make an old house new? BUT, having started please do the minimum and keep a shellac finish.
I hope that you enjoy your old house and do not remove all the signs of age -- those signs are the patina that makes the place special. If you want everything new you may as well buy a brick veneer!
This forum is about timber and the beauty of it as shown in woodwork and turning. You will not get the best advice about heritage work from those who only make new woodwork, no matter how expert they are at what they do (and many are very expert in that compared to me).
Regards
David
Do you have an old house to match the door? That determines the finish
Hi Dave,
If the door is in an old house then yes, I would certainly recommend shellac, as that is what would have been used and it gives a really great finish that shows the beauty of the timber. Now, as a personal preference, I have to admit to a dislike of orange flake shellac, BUT others love it and I respect that. I polish with the original button shellac, others love flake and it is worth looking at Ubeaut's offerings as they can provide an easy entry to a good shellac finish.
Your door looks like Californian Redwood if it is old enough, but later and similar doors were made in Oregon and Western Red Cedar (All North American conifer timbers that were imported here).
I hope that this helps. Feel free to PM if you want my supplier for the button shellac.
Regards David

Appropriate finish for that age (internal joinery and furniture) is button shellac

Hi Dave,
I have finished some internal Australian Cedar doors with brown button shellac and a lacquer brush and have had good results. Back in the 1880s button shellac would have been the only choice I think, though I do not know when flake shellac was introduced. The orange flake gives everything a distinct orange colour. Today you can buy all different types including different colour buttons and made-up solutions that are clear and harder than the original.
See photos below for effect with the brown button shellac. For furniture I find that applying the shellac with a rubber gives the best results by far, except for carved and small diameter turned sections. A rubber is simply a piece of fine, lint-free cotton (like old sheets) around a smooth pad of some wadding like cotton wool (roll form is better than the cotton balls).

However, for the doors, using a rubber would take a very long time and is not necessary. The lacquer brushes that I use are special extremely fine natural hair brushes - squirrel hair being one of them. As you can see, you get a decent result. The technique is to break the buttons into smaller pieces and dissolve them in metho. I use a 4 litre bottle from bunnies as it is cheapest. First you make up a stock solution with about 250 grams of buttons to 4 litres. You need to then filter the solution through some cheese cloth (or other coarse fabric of some kind) to remove the muck in it. Depending on my patience level I either break that solution down 1 part stock to three parts metho to make my working solution - or leave it more concentrated if I want a faster build up. The faster the build the more opaque the finish - less clarity and beauty of timber showing. Between every couple of coats - once they are dry - you must rub the finish over with very fine (800 to 1000 grit at first) wet and dry sandpaper. That rubbing down helps to keep the finish smooth and even. I rub down between the final few coats with 1200 grit. The paper clogs easily so you need a good, more affordable bulk supply like from the Sandpaper Man.
UBeaut sell a polishers handbook that most likely gives much better instructions than I have given here. I must admit that I do not have a copy as I was taught to polish by an Austrian cabinetmaker about 40 years ago and have developed my own versions that work for me, but the book would be a good start for someone just learning the techniques.
I hope that this helps.
Regards
David

Hi Dave,
I knew that question was coming and have been searching for the answer. It isn't that long ago that I bought new ones (after the Brisbane 2011 flood that ruined my earlier ones) so I should have the details somewhere - but just where escapes me at the moment. My original ones were purchased from Tas paints in Hobart and were over $60 each. They don't sell them anymore but they did give me a recommendation as to a new source, and I purchased from that source. From memory the new brushes were about $30 to $40 each. I am awaiting a call back from the owner of the store so will post the details if he calls me.

Tas paints come up trumps

Hi Dave,
Simon Desmarchelier from Tas Paints has come up trumps. The Woodworks Book and Tool Co, Sydney has them. Here is the link: http://www.thewoodworks.com.au/index...nufacturer_id=
The other brush I have is the skunk hair and it is expensive - about $83 now! The squirrel hair works just fine though!

Another supplier for fine hair brushes for shellac and lacquer
Hi Dave,
it was good to meet you in person today at the Brisbane wood show.
Leonhardy, the German company that makes these brushes tells me that their Australian agent is The Gold leaf Factory International Pty. Ltd. Email: [email protected] | Web: www.goldleaf.com.au PO Box 912, Frankston VIC 3199, Australia Telephone : +61 3 9786 2247 | Facsimile: +61 3 9785 1145.
Andrew from that company has contacted me to say that they have the squirrel hair brush at about $17.00 (plus postage of course) http://www.goldleaf.com.au/catalog/f...s-c-33_67.html
I have also been thinking about the finish for your doors. I do believe that shellac is the best finish, and that a brushed on finish is ok for doors. I also know that you have a critical shortage of time to prepare the room. Why don't you buy some shellac while here in Brisbane and use the finest brush that you can find? As long as you sand it back between every few coats you will get a good finish.
Regards
David
