 No idea about your paint but i bought standard wood paint, not fence/shed paint/stain, in yellow and purple to paint mine and it covered the old Johnston's wood stain up.

Nothing wrong with Johnstone's paints - it's usually considered a top brand.

We really need to know the type of 'paint' used before, and what the J's paint type is too.

'Shed and fence' paint - the stuff you get in huge tubs and is like a gel - isn't really 'paint' at all, and only works on rough sawn wood. Only the same type of 'paint' will go on to it and stick properly. Not sure what happens if you go for a colour change.

Types of the two paints involved?
