Sorry forgot B&Q do discount on multi finish buy and so £27.50p and the pva I should price at £5 for only using half of a tub tbh = £32.50p in effect there is £9.50 difference, interesting
Stats worked out of 5 bags if it was 4 well that would be very interesting lol
9.50 x 240 working days = £2280 so it's not really interesting at all it's a no brainer.
