Good evening everyone!

I wanted to quickly ask about the best sequence for applying the acrylic sealant between the ceiling and wall in a new build.

The ceilings in our new build will be covered with paintable fleece wallpaper and then painted white. The walls will have non-paintable fleece wallpaper (partly patterned).

When is the most practical time to apply the acrylic sealant between ceiling and wall?

I would assume the following sequence:

- Apply paintable fleece wallpaper to the ceiling
- Apply acrylic sealant between ceiling and wall
- Paint the ceiling white, including the acrylic joint at the edge
- Apply fleece wallpaper to the walls

Our drywall contractor advised us to apply the acrylic sealant joint after 6 to 12 months. We will be doing it now, after 4 1/2 years.

Acrylic is unfortunately not flexible enough at the junction between a rigid wall and a slightly movable wooden ceiling. It will always crack there. That is why a trim is used. It is different with concrete ceilings, where it works. An elastic alternative to acrylic would be MS polymer. It is paintable but more difficult to work with and more expensive.

Yes, that’s true. I remember they mentioned using a trim. I ignored that – I don’t want a trim!
