How long should you wait after applying patch work stucco to a block wall house ? I have patched many small and a few larger areas and am ready to paint. I read somewhere where stucco takes 28 days to completely cure ? The stucco patches have been on a week...is it ok to paint over them now ?
Thanks, Tim R
stucco patch is not stucco.
what does it say on the side of the can? is there an 800 # on it? if so, what did they say when you called it and asked this question?
Press 1, for English?
Bags of mixed or containers from the local diy borg? When I'm happy with small stucco patches from a container and after a few days I paint.
no can...80lb bag of stucco mix (quickcrete I think)..bag says 30 days but that's after two base coats and one finish coat about 3/4 inch total...I am just spreading top patches about 1/4" thick..with the typical southwest roughed up texture...so someplace it's even thinner.
seems to me the 30 days is for the complete job...with all three coats...that makes sense ? Question is what's the problem (how long to wait) with painting a thin patch layer over a 3/4 inch thick 30 year old stucco wall ?

Its not moisture that is the issue its the chemical reaction, so wait
30, but isnt that what the BAG says.
The paint would not know whether you have one layer or ten. Mortar and new plaster take time to cure completely. It is typical, for all the paint labels I can recall reading, to wait thirty days before primiing/painting new concrete.
I have used water based latex (DAP?) stucco patch from the box store. It is avail. plain or sanded and can be painted much sooner. Don't know how it is for real stucco, but works like a charm on our Florida concrete block/stucco. Even used it like mortar, with concrete pavers, to fill a defect on exterior wall where we took out an old, rusty fire extinguisher cabinet. It shrinks a bit when used heavilly, but another application after it dried filled in our problem area.
