Self-leveling compound 50 sqm pine floor

[Bezt]

And cheaper. But if you don't want to build it up in height, you might as well tear up the plank flooring first.

In hindsight, I regret not tearing up the old floor... The thing is, I have framed the old interior walls and built two new interior walls on the existing floor... believing that I could simply use leveling compound to make everything even.

Yes, in hindsight, I regret not tearing up the old floor... The thing is, I have framed up the old interior walls and built two new interior walls on the existing floor... in the belief that I could just self-level everything.

NO PROBLEM!
You can saw alongside the walls and fix the rest!
You'll be satisfied!
