Wood preserver pigment

[Sonic70]

Hi All,
I have a 3 year old 5l tin of barretine wood protective treatment in golden brown. When I poured some out today it looked like if was full of brown bits, I think the colour has separated to an extent even after a good shake. I'm using it on the interior plywood garage roof. Is it still OK to use or should I bin it.

The colour pigment is irrelevant to the preservative properties. I think you mean it is a wood preserver.

You can try using a mixer spinner, like a propeller on a long shaft, that fits an electric drill.

You could use a wood dye, first, to colour the timber. I find the spirit based dyes, such as Blackfriar, to be much better than water based dyes, but you have to let them dry thoroughly before trying to use a water based treatment on top, as the oil residue will prevent water wetting the surface. With Cuprinol wood preserver, you can add the dye to the preserver so the colour soaks in. I don't know if that will work with Barratine.

If your product is a water-based treatment that leaves a tinted waxy film on the wood, like a fence stain, then the bits you gave found are probably the wax, which will reduce its effectiveness to the extent that it has precipitated out.

Thanks for advice. It is oil based. I will give it a good mix with the drill and mixing tool.
