Hidden defect or not - can I proceed with this?

[Henrik Larsson78]

The base of our old house needs care. When the handyman knocks off the plaster, he notices that the base is smoothly plastered over an existing roughcast. The problem is that the roughcast is painted with plastic paint.

The handyman suggests that this may be a hidden defect. Is he right about that? Is it worth pursuing that angle?

Take care, everyone

The plinth of our old house needs care. When the craftsman removes plaster, he notices that the plinth is smooth plastered on previous roughcast. The problem is that the roughcast is painted with plastic paint.

The craftsman says that this could be a hidden defect. Is he right about that? Worth pursuing that track?

Take care everyone

Henrik

Yes, because you couldn't see that it was roughcast without destroying the plastic paint.

What is the problem? What compensation do you want?

What is the problem? What compensation do you want?

Hello! Actually, two errors. Firstly, painting with plastic paint on cement render and then plastering over it.
New plaster adheres poorly to plastic paint, which is why it should be removed.
I imagine that the compensation should be the additional cost. I don't have a quote but maybe 50K.

Hi! Actually, two issues. Partly painting with plastic paint on lime plaster and then plastering over it.
New plaster adheres poorly to plastic paint, so it should be removed.

I think the compensation should be the additional cost. I don't have a quote, but maybe 50K

The compensation is based on how much the final bidding price would have changed if the issue had been known during the bidding, not the cost to fix it. A bathroom for 300,000 in a villa for 10 million is too small of an issue in that price range, for example.

How many square meters are involved and why can't he repair it with a Systemputs instead of tearing everything down at your expense? Painted base to protect against weather is very common and rarely an issue.

I understand how you're thinking but I don't really see that it constitutes an error in that sense.

For example, it's "wrong" if someone were to paint a wall with ceiling paint, it's not correct but it works. Similarly, it seems the smooth plaster on your "old" house has stayed for quite a while? How long has the smooth plaster been there?

I think it's doubtful to consider this a mistake. Over time, there have been recommendations for all sorts of unsuitable colors. And at the same time, there have always been "knowledgeable" people who confidently claim that it is wrong. In the 70s, the so-called "Tosse Magnusson" facades emerged (it was Princess Christina's husband who imported the method from the USA), essentially a plastic paint that completely ruined tens of thousands of house facades.

The paint industry, for example, insists even today, with the stubbornness of a fool, that their plastic paints are suitable for the inside of basement walls. "It's good if visible moisture damage occurs because of the paint, so you know there's a moisture problem."

I assume this is a relatively old house. Then one can expect some questionable building methods that the house has been subjected to over the years.

I think it's doubtful to consider this a fault. Over time, many unsuitable colors have been recommended. And at the same time, there have always been "knowledgeable" people who confidently say it's wrong. In the 70s, the so-called "Tosse Magnusson" facades appeared (it was Princess Christina's husband who imported the method from the USA), in practice a plastic paint that destroyed tens of thousands of house facades.

The paint industry still claims with the stubbornness of a fool today that their plastic paints are suitable on the inside of basement walls. "It's good if there are visible moisture damages due to the paint, so you can see there's a moisture problem."

I assume this is a relatively old house. You can expect some questionable construction methods that the house has been exposed to over the years.

You are right. The house is from 1923. The stucco work is surely 10 years old, and the painted plastic paint could be significantly older. The craftsman who pointed out the "fault" is experienced and credible, but I think it's a long shot to claim hidden fault in a legal sense even if it is, by definition, a hidden fault.
