Topic : paint - technical question

Hull all prepped and ready for colour coat. Question is: Are Cellulose thinners [which I have] ok to use with International Toplac or do I need to get a  specific one? I don't want to botch a weeks prep for the sake of the wrong thinner
Any help appreciated.

I think you answered your own question. I always (ish) follow the manufacturer's recommendations - not least if it all goes pear shaped you can try and pin this on their product. International's datasheet recommends Thinner No 1 or No 10 if you are spraying.

What Andy says. I've been caught out in the past using apparently similar thinners which weren't 'quite' the same. Fortunately not on a boat, I hasten to add.

Thanks for advice, thought I might be answering my own question, but always best to check.

Will pop to chandlers once wifey comes back from the links.

Thanks again

Number 1thinner is white spirit. Don't waste your money!

Thanks Chris, just googled it and yep, you're spot on.

Found this snippet "IIRC at one time International Thinners no 1 were actually labelled as white spirit."

Saved a few bob there.

I've just finished using No 10 thinners with toplac and although its smell stays with you for days, it's the right one to use - 'faster' than No 1 (didn't know it was white spirit!)
Been using one of those HVLP sprayers from B+Q and thinned at 20% it works well - found it needed different % for diferent colours though, so it may pay to experiment.

should have added No 10 is the one for spraying, No 1 for brushing, like Andy said,

Id be very interested to know what the no10 thinner actually is. We spray blakes with white spirit with excellent results, certainly never thought of using a different thinner. The old one pack oily was different, very strange stuff but a brilliant product shame they pulled it.

Any ideas if there is an alternative to No. 5 thinner? Used for Hempel / Blakes EPU on the insides of BAU.

No 10 aka YTA063

Seems to be based on toluene not xylene

I have spoken to International and they advise spraying with either 910 or 920 which are professional thinners for spraying industry

Brushing is no 1
