    BLO-how long to dry?

    I covered a workbench top with a door skin. I will use it partly for assembly. I decided to use boiled linseed oil as I figured that would help with the glue issue if the wax becomes thin. I don't know if that is right or not. I have never used it before and do not have a fininhing book. My questions are: 1. How many coats? I am thinking that when it quits soaking in that is enough. 2. How long between coats if I need more than one. and 3. How long shoud it dry before putting wax over the top of it?

    Allen, while no expert, I would thin the first coat 50/50 BLO and thinner. Let it soak for 30 min or so then wipe off. Let that sit for two or three days then give it a good coat of BLO, wipe off and let it dry for at least a week, two or three would be better. If you don't wipe it off it will never dry and will become sticky. DAMHIKT

    Thanks Cecil, To late for thinning the first coat as I put it on a couple of hours ago. Seems like thinning it would have been a good idea to let it soak in deaper. I guess that now I will just wait a few days and go with another coat and wipe it down and wait two or three weeks and then put a few coats of wax on it.

    Allen, I've always been told that the "smell" test is a good rule of thumb for BLO. When it doesn't smell anymore, then it's time to put your topcoat on. It sounds kinda silly but when it stops smelling the it should be cured.
    Thanks, Mark.

    Due to the ordor that it puts off that does seem logical.

    My only experience with boiled linseed oil is observing what others have done on gun stocks. Too often, I have seen cases where the finish seems to never dry and remains forever sticky. That is why I avoid it and use pure tung oil instead. The quality of the product seems to determine if it dries properly. Also, after a period of time, low quality products can get sticky again. Now, this is with something that is handled frequently and gets exposed to the elements. The only product that I know of that has a reputation for going on beautifully, drying properly and remaining that way over many years is Birchwood Casey Linspeed. I don't know what is different about it, but, by reputation, it is the best.

    Now you tell me Frank. Since that you mentioned it I think that I really meant to use tung oil. When I was at the store I was trying to remember what some guy said a while back that he used on his MDF assembly table and all that I could come up with was BLO. Live and learn I guess.

    Allen, as said above, BLO should dry at least a week or until you can no longer smell it....It will soak in and dry. I use it often after sanding on cherry and walnut prior to shellac and top coat..

    Wow, I haven't seen that name around in years. I used Linspeed about 25 years ago as a finish on a lap steel guitar I made, and it's still holding up beautifully. I was under the impression that Lindspeed was just thinned BLO, but perhaps they are adding other things to it. All I know is it created a nice glossy finish after several coats (and good wax afterwards).

    Allen, the others have given advice that mirrors my own experience with BLO. The only times I've run into problems with BLO is when I don't wipe it off soon or thoroughly enough. Several thin coats seem to cure much better than one thick coat. I'm sure Marty can relate, after getting the first coat of BLO on his shop floor a bit too thick.
