After a year I have the following problem, pieces of plaster (1+ inch
deep, 4"x5" on the surface) from vertical walls occasionally (every 4-5
months) fall off. The problem according to a contractor is the cement.
I think that's without doubt as the plaster falls of with a small piece
of cement always ( about 1/8" ) .

The reason for this was attributed to bad cement mix: The original
fault I was told was the addition of too much water to the mix. does
that sound plausible? provable? The gravel seems to be also a bit too
oblong, slits rather than rounded, but of medium/fine size.

The remedy is quite expensive, injections into the cement. But only
local treatment. Given the rather rare occurrences, and since I repaint
every 2 years maximum, does it really worth it? ( total house surface
1600sqf)

Other solutions
- total replastering ? ( with global cement treatment)
- glass fiber cloth ? ( on existing plaster, without cement
treatment)
- covering with prefabricated plaster on metallic trellis base, on
top of existing regular plaster.

Your ideas?

I could also pursue legal remedies but... am not sure what is best.
it's a bit of gutting experience.


Cement and plaster are two completely different applications.
Stucco does have cement in it. Stucco can chip and peal if improperly
installed. If you bought the home new use your warranty.

Plaster is typically used inside on very high end homes.

Your statements for me are confusing and hard to understand.
