Plasterboard on fiberboard

[daniel_jagerman]

Hello
I'm planning to spruce up a wall (with textured wallpaper and several layers of old wallpaper) and I'm thinking of attaching drywall directly to a Tretex board. The Tretex is probably a few years old and is a bit soft. If I screw the drywall in, I'm thinking it might start to shift south over time. As a solution, can I let the drywall rest directly on the floor as "support"? It's a plastic/laminate-type floor with underfloor heating.

What do you have behind tretex?
In older houses with tretex, there might be a plank wall, and in that case, just choose screws that grip into it.

If you are going to install drywall with all the work that spackling and new moldings entail, take the opportunity to remove the Treetex first. Treetex tends to have an odor, so it's good to get rid of it, and you'll have a new wall that matches windows and doors with standard moldings instead of ledge moldings.

I think it's more or less directly on a brick wall. Maybe some thinner framework

If you're going to install gypsum anyway with all the work that spackling and new moldings entail, take the opportunity to remove the Treetex first. Treetex tends to smell, so it's just as well to get rid of it, and you'll have a new wall that fits against windows and doors with regular moldings instead of step moldings.

It's a small wall without doors and windows, so it doesn't matter if it adds a bit.

We are renovating the living room and have put gypsum on tretex directly both because we have grooved in the tretex for electricity and also because it probably has a small insulating effect.

If you're going to put up gypsum board with all the work that spackling and new moldings entail, take the opportunity to remove the Treetex first. Treetex tends to smell, so it's a good idea to get rid of it, and you'll have a new wall that fits better around windows and doors with regular moldings instead of step moldings.

Question out of personal interest (I'm considering whether to just put renovation gypsum over the Treetex in our summer house this spring, or remove it and start from scratch) - do you have any experience if you can eliminate the smell by putting gypsum board over Treetex?

 

[Janus82]

I have never tried to incorporate treetex so I don't know if it affects the smell, but it seems doubtful. I only know that there is a difference between the rooms that have treetex and those without when it comes to scent. It doesn't smell much, but it's nice to get rid of it.

There must be a solid material behind the plaster where you screw. Otherwise, the screw heads will go through the plaster. Remove threetex or add studs on the outside.

Hi, may I ask how the result turned out? Did you screw the gypsum to the wood behind the tretex? How did you handle the joints between the gypsum boards?

Yes, screwed plasterboard screws into wood behind the tretex. We used fiberglass tape on the joints and then filled it with spackle. I am pleased with the result...

Yes, screwed drywall screws into wood behind the tretex. For joints, we used fiberglass tape and then putty. I am satisfied with the result...

Thanks for the response! They should be long drywall screws, right?

Thanks for the reply! They should be long plaster screws?

Well, I think I used 35mm with 6mm renovation plasterboard
