At the risk of opening up some old wounds.....
Just finished rendering 3 boundary walls (both sides and pillars) and went back to inspect my work following a frosty night. (AND NO I DIDN'T USE PVA
)
On close inspection I noticed a couple of very small cracks in 2 of the sections although the surface is sound (no hollows).
Thinking my worst nightmare was about to repeat itself I remembered that on these 2 particular wall sections, I had added waterproofer to the scratch coats by mistake . Which shouldn't be a problem - or should it
I used 5:1:1 on scratch and 6:1:1 on the top coats and wetted the wall down with a hose as the day was sunny and walls dry. (I even got sunburnt) but the temperature dropped to -2 that night.
Any ideas
