Hi, I have a raised bungalow and the exposed foundation walls are roughly three feet high from grade outside. The previous owners painted the parging with latex paint. I would like to stucco but not sure how to remove the latex paint from the parging since everyone tells me they will not sandblast it off and that there are no pressure washers with enough psi to strip it. I really need help to get this paint off and secure the stucco to a solid base
Thanks for replying
When deck posts exceed what the prescriptive code tables allow, it's time to consult a structural engineer for post sizing and possible bracing.

What's the issue with sandblasting?
I suppose you could use a regular paint stripper, wash well, then etch with muriatic acid.
Why No Sandblasting?
We have a traditional, 3-coat stucco home in southern CA, originally built in 1961. It had been painted a few (perhaps 3?) times in the 1980s - 1990s.. The home was to receive a new "color coat" to match an addition. The general contractor hired a sandblaster to remove the paint and otherwise help prepare the old substrate for the new color coat.
The old latex paint hadn't really penetrated the old stucco at all. The sandblasting seemed to remove ALL the paint, and much of the original color coat. If your foundation is really parged with genuine concrete, I would think it would be EASIER to sandblast than CA stucco.
This happened in 2001, and the "new" color coat on the old stucco has held up well with no problems.
I'm surprised sandblasting isn't an option for you...it should be the cheapest and quickest route. Since you only have the foundation, I suppose you could go with chemicals. Our stucco work was done by professional plasterers [sub'ed to the general], who only did this type of work; they were satisfied the sandblasting would suffice, and they were right.
Will they not sandblast due to lead paint concerns?
The sandblasting companies are concerned for the neighbourhood. Saying the dust will be everywhere and most people will be upset with me for them having dust and dirt everywhere. I thought sandblasting would of been the easiest but this is turning into a rather big mission. One sandblaster told me to use a grinding wheel.....but that seems like it would take forever !
It is, of course, possible to sandblast and contain the dust and debris, but likely either the sandblasting company isn't equpped to do this or they don't think you'll want to pay the extra $$.
