Hello,
.. that is absolutely wrong ... on the contrary .. the joint can handle more than a minimum exterior plaster ..
I’m still not sure whether you practice a profession characterized by arrogance - which would be the majority of the certified idiots in our industry (sorry E.Curb - you are definitely not included), whether you are a young buck whose antlers haven’t been changed often enough yet, or whether you just confuse self-confidence with knowledge ... in any case, you are not lacking in confidence.
It is not wrong. I can show you façades - whether finished with synthetic resin or mineral plaster - where a pressure washer provides good service for years. Of course, the proud homeowner does not clean the entire façade, but only the weather-exposed side - and it works excellently. With a little less pressure on one, with a little more on another. Good pressure washers can be adjusted ... y know
Rhineland regards
