Looking for a bit of advice guys and girl.
Completed a small rendering job last week, the side of a garage, hack off old as was all blown and re render.
Scratch coat was layed on over SBR slurry at 5:1 with waterproofer, left it a week before topping it off.
Scratch was solid.
Gave wall a light dampening down before topping off, waterproofer was definitely working.
Topped it off at 6:1:1, floated up lovely, didn't dry too fast etc/
Came back yesterday to fix pipe brackets back on and gave the wall close inspection, all looked fine and solid, not dry and dusty, not blown at all but then noticed a small patch about a foot square where a few hairline cracks were, gave it a tap and this one area is blown.. But everywhere else is solid.
Any idea what could have caused this?
