You used good exterior materials
I think caulking was a waste of money
?Coking is a petroleum compound
Porous materials like stone
Silicone oil into the pores
Penetrated and physically cleaned
Pollution is not removed
then
Why? With buildings like this
?Is there any building that doesn't look like this?
That's right? It's a few thousand won cheaper
It becomes a source of pollution
If you give several thousand won more,
Functional silicone can be used
It is only a difference of several thousand won
Used cars also need interest in buildings that are 100 times and 500 times more expensive as you can see carefully when you first buy them.
