OK, thanks. So what still available now, that you would class as
"traditional" varnish?
Any of the high VoC content jobbies, and not the quick drying type. (the
latter are not as hard wearing)


What's puzzling is that none of the high VOC varnishes I've seen in
the sheds are billed as floor varnishes - for example:

http://www.wickes.co.uk/Professional...sh/invt/170505

I also have a tin in the cupboard of Ronseal Ultra Tough Satincoat,
also high VOC, which I used on a worktop. The tin suggests uses on all
sorts of furniture, but omits to mention floors.

I'm puzzled that while the sheds continue to sell high VOC solvent
based varnishes, the only ones they have that are explicitly floor
varnishes are medium or low VOC water based varnishes. Makes no sense
to me.

Maybe one reason is that use on a floor can be overwhelming due to the
high VOC. On more modest things the absolute amount will be lower.


Which is why the two pack acid cat floor varnishes don't seem to be
generally available now. They have the advantage of being extremely
tough and totally clear.
For a mellow yellow look, I'd use a standard polyurethane, even if it's
not specifically for floors.
Water based varnishes are certainly clear in the sense that they don't
change the colour, but they still have that cling film look, which I
think is the nature of the acrylic beast. The harder the resin, the
higher ambient temperature it requires to cure and remain clear, so
d-i-y stuff is never going to have the toughness you can achieve in a
controlled environment
