hi all, i want to render an external concrete block wall i have built, what mix do i use ? its a cavity wall so do i need to add a waterproofer ? how long between coats ?
also i was wondering if i used a 5;1 mix for the blockwork would a stronger mix of render have any effect on the blocks in any way as that mix could be stronger ?
thanks
