Can you apply microlit on aerated concrete and maintain diffusivity?
Hello!
My painter has puttyed all interior walls with sand putty. After this, the plan was to apply microlit and paint on it. The walls are made of light concrete.
But now we are considering if it is a bad idea because apparently, when you glue the microlit, you lose the wall's breathability??? The glue that attaches the microlit is the problem. The exterior should be lotusan render. Is there any way to get around this?
Best regards,
Rebmic.

Why don't you paint directly on the sand filler?
If you want a more impact-resistant surface than sand filler, sure you can use mickrolite, but why should you have diffusion-open walls when you've painted, as you won't have very high diffusion anyway, and also you don't want moisture in the wall because the plaster outside can freeze and crack if moisture gets in the wall.
I would sand filler and sand the surface and then paint with silica paint... for outward corners, I would reinforce with special fiberglass corners that I spackle over... mikrolite will only become a problem over time in the walls. For the ceilings, I would use mikrolite!

Hello!
Sorry for jumping into an old thread.
But I am in exactly the same situation as you, considering broad spackle on aerated concrete walls with microlit over it. How did you do it? Did you use glue and microlit?

Bumping this thread, as I am wondering about the same thing.
Diffusion openness in lightweight concrete walls with microlit, how does it work?
Are there good adhesives that don't seal the wall?
