my recipe at the moment is 1:1:1 of turps:boiled linseed oil:estapol

and uno how as your oil finish drys, glossy patches are left. hot spots. so you gota wipe it over before it gets too tacky to get rid of the patches.

I find this process a bit bloody annoying. cause they keep on appearing....so you gota always be around to get them before they dry too quick....and there's always a patch I miss down the track.

do you know if theres anything you can add to the mix or whathaveyou to avoid all this.

Jake, haven't had that experience, maybe cos I'm using commercial products.

So just off the top of the head ...

I guess you are flooding the piece and then wiping off the excess before it gets tacky?

Maybe increase your solvent proportion.

What happens when you build up the coats? Same problem?

Maybe try wetsanding the first coat to fill the grain. Or as a last resort apply a sanding sealer first off.

Good luck.

ta Ern,

yep, I'm flooding the piece and wiping off. same problem every coat. its as though I wipe it down and they still keep appearing over areas I've already wiped down.

I'll give your ideas a go. ta.

I find that the same thing happens with Tung or DO when working on larger pieces.

At first I tried increasing the turps in my home-brew, but found that while it gave a longer working time it also tended to dissolve the already applied coats, making them tacky in patches instead... which is an even worse problem. :doh:

As I have a dislike of sanding sealers I like to flood-coat and wet-sand for the first coat, let it dry for a week and then do a finishing sand. This seems to reduce the problem, but doesn't eliminate it.

So I work in smallish areas at any given time, trying to blend the next area in after wiping it down. The "overlaps" between areas tends to be obvious for the first couple of coats, but these start to blend in after a few more. (Well... normally they do. :rolleyes:)

Works for me, anyway. Your mileage may vary. :D

I've run into this a number of times and so far the only cure I've found is to keep your eye on it and wipe ASAP. :(
