HI - just going through the first stages but would like to get the treatment sorted out - are we using OSMO ? if so which one - my bench is f/e ply legs and birch top
I wanted to use Osmo hard wax oil satin finish, but none of the stores had it. One store had the Osmo in high gloss, but I didn't want a glossy work surface. I went with a different brand in a semi-matte, and am pleased with the results.
I used
this teak oil. Whatever, suggest use a short hair roller? Roll over holes to keep clear?
Even then, I have a piece of dowel with sandpaper to clean out those which received a bit of
sealant.
I brushed my finish on for both coats. I had a 250ml can, and the roller would absorb too much that I couldn't recover. I didn't bother with cleaning the holes for the first coat because the oil was absorbed quickly by the Valchromat and there wasn't much to wipe off. However, the second coat was not absorbed as much and I did clean out any oil that built up in the holes.
My lesson learned on the second coat was to pay attention to the instructions on the can. When the manufacturer says wipe off after ten minutes, they mean ten minutes. Ten shall be the number. Not nine, except when going directly to ten. Eleven is right out. And don't even think of twenty, like I did.
The oil was not a problem on the first coat because it was mostly absorbed, but after the allotted time on the second coat, it started to set up and became difficult to wipe off and leave a good surface. I was not happy with the finish, and after it dried for two days, I went over the surface lightly with P400 grit on the orbital sander. Then I applied a new coat in small sections, five total, that I could handle easily. Success!
