What are the advantages of porous paint?

Dear Maid Marian,

Interesting name! Are you into renaissance activities?

Some types of porous paint are used on things so that they will be more historically accurate in the way that they are finished. I.e. houses that are centuries old, early musical instruments, particularly keyboard ones.

I have made types of harpsichords. I would prefer to decorate them in a way that would be like they would have been when they were first invented.

As far as physical advantages, there are both good and bad points to consider.

There are a number of comments concerning porous paint on the following sites. I hope that you might find them helpful.

I believe that the primary advantage is that porous paint allows the material it covers to "breathe". It permits any moisture inside the wall to escape.
