- Mortar applied too thin-less than 3/4"
Saving the boss man's money is no excuse. Hurry up
construction schedules aren't
a valid excuse either. On block walls usually cracks
appear at every block joint
when the basecoat mortar is too thin. If one wanted to
see every block joint, why put stucco on in the first
place. This quick method may gain short term approval,
and short term profits that are quickly spent, but good
work is what gets the next
job. I say be the turtle here- doing good work will
always bring more work.
The standard thickness of cement stucco is 3/4"-7/8".
True, there are
places that the mortar thickness is more or less, to
make up for irregularities
in the framing. 3/4" should be still considered a
Thickness equals strength. Thin mortar equals weakness.
Don't get gypped. Check the thickness while it's going
on before it's too late.
