I'm using some Ronseal diamond hard satin clear 'water based' varnish on a
table top. It says on the tin to use a *synthetic filament * brush, which
is annoying, since all my brushes are bristle.

Would using a synthetic brush make any noticeable difference to the final
finish? Anyone know why they would recommend a synthetic brush please?

YES! use a synthetic brush with a water based product. You wake up in the
morning and your hair is wild and wooly, you jump in the shower and wet you
hair down and it become limp. Water based products make you natural bristle
brushes limp also.

Also, don't buy a cheap synthetic. Look for Purdy, Lindser, Wooster, etc.

I don't suppose the manufacturer would know anything about their
product, huh?

But it isn't only Ronseal, synthetic bristle brushes work _much_ better
w/ water-based finishes owing to the tendency of water to soften natural
bristle. If you're at all interested in a quality finish, follow the
recommendation and use a good quality brush, not a 50-cent cheapie.

Because it works better and gives a better finish?

I've ruined a perfectly good high quality bristle paintbrush
with water-based polyurethane. (didn't say anything about it on
the tin, unfortunately). The stuff just goes off in the higher
parts of the brush. Also it doesn't flow out very well, which
makes for a patchy/streaky finish. It flows much better out of
synthetic brushes and it doesn't stick to the filaments the way
it sticks to bristles, so you don't end up chucking your
favourite finishing brush after the first coat.
