Just found an old tin of Schooner varnish which says it needs International 333 thinners. The varnish is years old but stil liquid.

I have a more recent tin of International Thinners, which says it's "suitable for all classic varnishes". The reverse of the tin indicates it's Thinners #1

Can I use this thinners with this varnish?
 
Found the current International website says Schooner is thinned by No.1 Thinners- so unless the formula has changed seems it will be OK.
 
I always though thinners no1 was white spirit ,but that not what the safety data sheet says!

However the Product data sheet does say that it is suitable for Schooner varnish:

"Thinner No.1 is suitable for thinning and/or equipment cleaning in association with: 1-Pack Paints and Varnishes - Yacht Primer, Toplac®, Interlux® Super, Interlux Satin, Pre-Kote, Interdeck®, Danboline, Interstain, Original, Goldspar®, Goldspar Satin, Intertox®, Dex 1+2, Schooner®, Intertuf® JBA016/Interteer "Vrij", Interpreg, Interfill® 100."

Although the data sheet for Schooner does say use thinners 333 I cannot find any info on that.

See what you can find for yourself on the website http://www.yachtpaint.com/uk/

Found the product data sheet (and the safety sheet)now "Premium flow-agent for thinning Brightside and other 1-pack paints and varnishes.

Still dont really know what it is though.
 
I have just been using Schooner. At first I used white spirit to store brushes overnight, but I found the varnish residue hardened at the bottom of the jar and in the bristles. At great expense, I bought a tin of 333 thinners, as specified on the varnish tin, £9.50 for 500ml, ouch! It does exactly the same as white spirit, I've also tried petrol.
The only way I find I can avoid Schooner hardening in the brush is to get the bulk out with thinners, and immediately wah with hot water and washing machine detergent. I've not tried to thin it with any of these liquids.

[/ QUOTE ]They're both spirit-based thinners. No 1 is basically white spirit; No 333 has lighter petroleum-based distillates as well. MSDS for 333 is here.
 
Thanks i did eventually find both safety sheets but the description of them did not mean much to me. More useful were the lists of uses on the product data sheets.

I have found that both work equally well to clean Schooner varnish from brushes, but if you want to thin the varnish then No 1 behaves better.
 
Thanks guys, all these different Thinners numbers make for confusion, and I too could find nothing about 333.

Just managed to do the first thinned coat on my tiller, and UV sprayed my sprayhood in the back garden before the rain came- hurriedly put it all away in the garage so something achieved today.

i have just given my Vertue 7 coats of schooner after rubbing and stripping back to bear wood ( hardwood teak and mahog ) the first three coats were mixed 50/50 with turpentine and the next 4 were mixed with 10% owertrol oil , between each coat i rubbed down lightly with 240 grit dry then washed down with soapy water and dried with kitchen towel , it takes me 2 hours to rub down and 1 hour to varnish the finish is superb and i have to do two more coats to be totally happy, regarding the brush , i use a very good brush about 7 euros and when i have finished varnishing i get as much varnish as possible out of the brush and then leave in clean cold water up to the stock of the brush , i have left this way for two weeks before and when ready to varnish again knock the water out of the brush and use paper towel , you are then ready to varnish , if you ever use thinners on a brush it starts to harden the bristles even if you wash with warm soapy water , i believe you can leave a brush in water for quite a long time and it will still be good as long as you ensure the bristles are covered in water ,
