A bit off topic but I hope someone has some guidance. I have some cracks in a garden wall, not supporting in any way. The more I read the more confused I've got - What's best to prep & fill them?
Just rough it up, wet it, remove anything loose then a sort of mortar mix - 3 to 1?
Ok. I'll get a photo on - I guess the repair technique is dependant on the crack? Before the the pic arrives, they are max 10mm wide, probably a bit deeper than that. Cheers.
Ok, I can't attach an image and have no server space anywhere. I'll have to describe it. It's actually not as big as I thought 5mm max but has cracked through the wall so it's deep. the wall is breeze blocks then rendered in something that looks like concrete / mortar
