Topic tags/keywords: shellac linseed finish appropriate steelwool mortise tenon keyed chair

I am just about to add a finish to a chair that I have been working on for quite some time. The chair has alot of keyed tenon joints and I am wondering what the most appropriate finish would be. I have used shellac in the past, on dark Tasmanian blackwood and the finish was beautiful rubbed back with a bit of ultra fine steel wool. But for this project I have reservations about the shellac because there are lots of little nooks and crannies + mortises which I’m worried that the shellac will collect in. I have never worked with linseed oil before—so any tips would be appreciated/ any suggestions other than linseed oil. I am after a very natural finish that alters the colour of the wood as little as possible.

You could use tung oil which is a little more protective than linseed. Spray rattle-can lacquer, in light coats it will not pool. Or rub on the shellac so that it doesn’t pool.

You can mix the linseed oil with turpentine and add a little extra japan drier to speed it up a little.

there are more BLO reciepies that you can use than you can shake a stick at, both commercial and home brewed. Most work well. If you plan to use BLO straight, use light coats. Timing between coats really depends on the wood. I can coat some old plane handles 2 or three times in a day, but normal kiln dried lumber is typically a multiple day dry time.

I am not sure what wood your chair is made of. If it is maple or cherry or something similar I would start with thinned BLO as noted above. After a few days drying time put on a dilute coat of Zinser’s Seal Coat (Shellac Base) [50% Seal Coat and 50% alcohol]. After a few hours, rub this down with #0000 steel wool then wipe on several coats of diluted polyurethane (50% poly and 50% mineral spirits). Rub this down with #0000 steel wool and finish with Minwax Finishing wax rubbed in with #0000 steel wool then buff.

Shellac wouldn’t be my first choice for a chair, but you can get rattle cans of shellac that would help with the nooks and crannies. I spray it anywhere I can’t pad it on…..which is those things with nook and crannies, and it turns out very nice.

I agree Linseed oil is a poor product . If you finish it in dewaxed shellac you can always add a poly later if you don’t care for the shellac finish because shellac will allow almost any finish to adhear to it. Shellac is a far better product than Linseed oil but still is not the water resistant. If you can spray on the finish with a paint gun or rattle can and that should help you control how much finish goes where.

I wouldn’t use shellac on an outdoor chair but it is plenty tough for an indoor chair unless people will be resting their drinks on the arms (in which case you should kick them in the shins). People used shellac on floors for years until varnish became readily available.
