finishing vic ash

Hi All,After a few mishaps i was wondering a good solution to use to filla few areas of small chips, raised grain etc.

Anything larger i've used either clear epoxy or tinted epoxy.but for the small hardly there as per photo i'm in two minds to try fill with putty / wood dust mix or try a slurry method with osmo.Finishing is planned to be osmo raw

What's everyone using?

For timber as lightly coloured as this, I'd use both methods. PVA/wood-dust for the larger chips, but a wet-sand to fill the bulk of 'em with slurry.

The results won't be 'invisible' fills - the glue/dust tends to be more obvious - but generally look like minor natural defects in colour.

I prefer the glue/wood dust filler over a commercial timber filler because it can be a right PITA getting the commercial filler in a close enough colour match, but primarily because of my scottish ancestry. (Short arms and deep pockets. ;) )

Unless I'm looking at the wrong defects, a smoothing plane will clean it up nicely.

Kind regards,
Lance

If it's small, I've been using some of this medium CA glue https://www.timbecon.com.au/ca-cyanoacrylate-super-glue with activator if needed. Seals and sands easily without the long waiting time of epoxy. Epoxy for the big stuff with a drop of black stain mixed in.

Thanks for the replies,

I'll give the cyanoacrylate a go maybe as its all minor stuff now anything major i filled with either clear epoxy or as you said with a drop black (I've been using black iron oxide as thats what i had around)

I might give a few spots a god with the dust / glue method just to try it out.

A plane would work but i looks like its just mostly 1 section / board so in my very amateur hands i'm likely to make a mess and cause it to be be unlevel

Could you please explain the “wet-sand/slurry” method?

Cheers

It's nothing special. Apply a coat of whatever I'm finishing with (usually Tung Oil, but it depends) and wet-sand with a mid-range grit. Say about 360-480grit, but this depends on the timber. Fine-grained timber I may go higher; for coarse-grained, possibly lower.

Let it dry, cut back with the same grit, then continue finishing as one would normally.

Vic Ash can be prone to small sections breaking away and lifting, almost as though you've worked against the grain. When you're stuck with such a recalcitrant piece, no amount of planing or sanding will help... what you remove just reveals more. These pieces respond very nicely to spot filling where needed and a slurry coat, which has saved my bacon on a few jobs. ;)

Thanks for that

This is essentially what i did when i first got a tin of osmo on a test piece. As i noticed vic ash likes to break away if you get overly "aggressive" with it like you said.

Basically gave it a light final sand at 240grit put a thin coat of osmo raw and gave it a quick sand while wet, let it dry off, it was then a bit rough to the touch due to the dust / raised grain.
I then sanded at 400 just to smooth it off and level it out

Finally i did 1 more coat as you normally would. I let that dry and it was ever so slightly rough i gave it a few strokes with a very fine grit then wiped it off and it seems to work some what well.

The test piece didn't have as many tear aways / lifting so was curious if after filling the bigger ones if the "slurry" method as above would help fill the other smaller ones

Thanks Skew.i am aware of the wet slurry when finishing but I somehow interpreted your reference as something being done while sanding in the intermediate but before applying a finish.
Cheers

Good advice above.

I've used a fair bit of Vic Ash, but I thought to mention that if one gets it wet it has a nasty habit of turning a hideous green tinge. Applying an acid of some kind (I'll find my info on it - muretic?) removes the green.

My experiences are the same as above - if a bit wants to stick up it will not sit down! Just like bad hair before a date.... its always the way. My method is to apply/wick a little thin CA glue, no activator. It hardens up the recalcitrant fuzz and tames the sanding.

For making the dark colour I've used dry coffee grounds, India ink, lamp black (my favourite), black milk paint (from the Old Milkpaint Company) and RIT dye. All work. Just mix a little in to the CA, let it set, sand it back and it looks just like an inclusion.

These are just my experiences. I made a bunch of displays a while back and was the first time I seriously used Vic/Tas ash... oh man, what a learning experience! It was a nice result... but.... that GREEN!!!! OMG (doom!!!) :) . I avoid water and moisture completely now, even my hands. May be overkill/paranoia :)

On finish, my absolute Go-To for Vic Ash is Livos Kunos oil.... oh, seriously wow.... you really need to try it out! On Vic Ash it is like touching fresh silk.

Green haven't see that before, n another thread this benchtop got rained on when my patio leaked i managed to get most of the water out quite quickly and it's dried back to the original colour. I wonder if the green tinge is some type of treatment?

Hi All,

After getting this prepped for oil i've now gone ahead and used OSMO polyx clear matte on the under side.

It's now touch dry and i'm not overly happy with the finish as it appears there is different "sheen" levels.
The method i used was

1. Apply a thin coat using a white scotch bright and work into the wood
2. Wet sand with 320 grit
3. Let dry over night
4. Sand back lightly with 320 grit
5. Apply 2nd thin coat with white scotch bright

It's as if its drying at a different rate in different areas or my sanding technique is off when rubbing back so there is high and low areas? or the application was uneven?
It looks quite even application wise until about an hour later when its really started drying and its drying in a patchy manner.

Not too concerned about the underside but better to resolve the issues before moving to the top side. It's possible it just need longer to cure and level out?

I'm thinking to move to a microfiber roller for the top side with no wet sanding

Did you give the can a good stir? I usually sand to 180-220g and roll it on with a foam roller. Once the first coat is dry (usually overnight), dry sand with 320g and then go for a second coat. Maybe the oil didn't penetrate enough and you've wet sanded back to wood.

If I read correctly, you've finished the bottom without moving to the top? Probably a good idea to finish both sides evenly to minimise any warping issues.

With Vic Ash & OSMO polyx clear. I have had great success.
1. Sand timber @ 180.
2. Quality 4mm nap roller. Thin coat.
3. Dry overnight.
4. Wet sand (wet & dry 400+ with a flat block). Light sand!
Repeat 2, 3 & 4 as necessary.

Hi,

Thanks to all who answered!

I checked i used a 125ml can it had the rate as 125ml to 3sqm so the maths is about right.
To be honest maybe i didn't shake the can / stir it well enough it's certainly a possibility, i'll make sure on the next can i do this very very well.

It seems to have penetrated ok and is now smooth just the sheen level seems off, i'll move to the top this evening so it coated evenly as you suggested. I can live with an uneven "sheen" in places i can't see......

I think i'm going to follow mostly your process and not over work it or over complicate it.
As when i just used a brush for a thin coat with a slight rub between coats with 400 grit it came out fantastic.

Seems like you both have a very similar process.

1. Sand timber @ 180.
2. Quality 4mm nap roller. Thin coat.
3. Dry overnight.
4. Wet sand (wet & dry 400+ with a flat block). Light sand!

@graham that looks fantastic!
