Re-stucco house lots of questions!

Am getting a 1920’s home renovated. Location is Southern California. This is not a DIY post requesting help but one asking for advice on how to proceed and have contractors do the right work for the house’s specific case. Some questions:


Outside Stucco:
The outside stucco has multiple layers of paint on it which is beginning to delaminate. I have decided to get it restuccoed. I get conflicting advice from contractors that I should opt to 1) sandblast away the old paint, then some patching of cracks will be done, then brown coat and color coat versus or 2) scrape off old paint, power wash, have fiberglass mesh installed over entire house, then brown and color coat. For #2, I am also told a weep screed needs to be retrofitted as the house currently has none. 3) Another contractor said sandblast (or scrape and power wash), add wellcrete (or some other bonding agent) then brown and color coat. What would you do? Also, I understand the weep screed concept but is it absolutely necessary as I have never seen this on an old house before. Also, I know stucco is permeable cladding and it seems the layers of paint have protected the house from moisture so is doing a restucco a mistake? Should I opt to just scrape and powerwash then just paint again?

Thanks in advance!

these are all valid points. a consideration for sand blasting is the dirt and risk of lead contamination/exposure. I have resisted installing retrofit weep screeds when requested. It is expensive and I think hard to get a moisture resistant installation. As far as applying mesh there are materials that would embed the mesh then let you finish over that.

and bonding agents are only as good as what they are applied to so if you scrape and power wash there is a risk, albeit probably a slight risk of the paint letting loose and taking the bonding agent and stucco with it.


I probably am causing you to ask more questions than giving answers.
