Fence treatment

[Petemate]

As title, quick question.
I have a large tub of Ronseal fence treatment. It is quite thin, even after stirring. I have obtained a pump-up sprayer, and wonder if anyone knows if I can use the sprayer with this large quantity of preservative to avoid the purchase of yet more preservative under the banner of 'sprayable'. Obviously, I am a bit of a tight git/don't wanna throw anything away (my lad says I am tighter than two coats of paint lol)

Cheers all! Thanks for all the input. In the end, as I only have 6 panels to do, I decided to save the expense of the sprayer and use a brush. (well, the OH will be doing it lololol)
