Thanks, everyone. I couldn't think of a reason why they shouldn't mix, but I thought I'd ask as I'm no expert in these things. I picked up yet another pewter pint pot for £2 on Sunday (so I've five to do)....... it was a good morning all told - I got a 5ltr coloured Johnstone's pliolite masonry paint (which is enough to do my back walls) for a fiver and a set of four unused Wood Beaver augers for a tenner. :lol:
