Thread: Mirka Sanding Mesh

As I’d never used it before, I rang Osmo in Melbourne. They told me how to prepare the surface, what to clean it down with and they told me to go to 180 on pine. Looked great initially but started peeling off.

It’s a shame you guys haven’t had success with Osmo PolyX. I’ve been using it for years and love it.

My early mistakes were around putting the finish on too heavily. Osmo really does need to go on very very thinly. Mostly now I use a small piece of white Scotchbrite pad to apply it thinnnnnly, leave it for 15 minutes then wipe off well. Leave overnight and repeat.

As to sanding I follow Osmo’s product info sheet and sand to 240 (they say 180 to 240 for furniture):

I use Osmo on walnut, maple, cherry and similar - I believe Osmo make a special thin product for difficult timbers - high tannin content etc - but I’ve not tried it.

For anyone new to the product I’d recommend watching the two-part YouTube video on learning to use Osmo:
Woodwork Finishing - Learning to use OSMO Part 1 - YouTube

Good luck!

I’ve never had an issue with Osmo when applied correctly. Thin is the key. I use a microfibres roller and wipe off with paper towel. The second coat is the same but I prolly use half the volume of product. Raking light is important to ensure you are getting full coverage and a consistent sheen.

Another thing.

I find the ceramic net disks by SIA or Norton are much longer lasting than the Mirka product. Shame they don’t do them in 125mm

I just finished watching Part 2 of this video and now believe my primary issue was not allowing enough time for the stain to fully dry. The video suggests 3 days.

So annoying but hopefully thats it.

I assume the white pad that is used is white scotch bright?

Hi Damienol,

Yes. There is another YT video by Peter Parfitt (New Brit Workshop) in which he compares Osmo applied with three different white non-abrasive pads - one Scotchbright, one Beartex and one I can’t remember. All results were the same. The best results were when he lightly scuffed with a dry white Scotchbright after the first coat had dried.

Ive used osmo on timber sanded to 240. All my osmo issues has been applying too heavily - I just wipe it down after a few mins if I get too much on and have done 3 coats before if worried about it being too thin.

I also used livos on 2 tables for my parents and the durability sucked
