Been varnishing some furniture with what Ronseal call "Clear" varnish and it's full of brown/orange streaks.
I expected them to dry transparent, but they haven't.
What can one do (other than buying a different product) to stop this happening again? [I assume the only way to fix this furniture is to strip it and start over].
Having just checked an old tin of Ronseal "Natural Shades" varnish from the shed - by now it's actually a solid lump that rattles about - it clearly states on the tin
Application
"Stir well before use"
If you've got streaks, it's unlikely you stirred it very well if at all.
Is it water based ? I refuse to use water based finishes because of this problem. (Except I do use a water based sanding sealer because of its quick drying and easy clean up.)
There's a difference between "clear" and "colourless". The opposite of clear being opaque.
All polyurethane lacquers have a yellow tinge - don't ask me why. Which on wood usually isn't an issue, as it's not obvious.
From memory for a clear and colourless finish (it always used to be anyway) necessary to faff about with a two part cellulose lacquer or similar. Which meant using natural bristle or hair brushes as the thinners melted synthetic brushes.
When steeping PU lacquer/ varnish brushes in a jar of white spirit prior to washing them, out you'd eventually get a residue of brown varnish settled at the bottom of the jar.
Oh, and the instructions actually read "stir well before and during use". What about yours ?
I've had this problem with polyurethane & similar varnishes --- I think I mentioned it here before & was advised for such varnishes, "clear" means something like "as clear as this kind of varnish can be, but that's not colourless"!
I've used acrylic varnish on top of white paint without any discoloration, though.
