 Help with Stucco Cracks
I stuccoed the outside of the dome on Sunday & kept it covered with plenty of wet burlap (25 sacks) until last night. Tonight I noticed a mosaic of hairline cracks everywhere. I used the high temp formula from the chemist at Lumnite. 2 calcium aluminate, 2 sand , 1 Fireclay approx 3/4 thick.
I mixed the dry ingredients well & then added water to make a pretty stiff mortar.
What's wrong?
Is this normal? or shoud I re do?
Theres too many to grind & fill. See pics, I dampened the stucco down to highlight the cracks |
