Problem screwing renovation plaster

[ERJ]

Trying to screw 6 mm gypsum onto chipboard, on a lot of the screws the gypsum raises around the screw like in the picture. What am I doing wrong? I've tried several different types of drywall screws but it turns out the same.

It turns out that way with drywall screws of 6 mm, I think it's because the paper is reinforced with fiberglass. 13mm boards are better to use.

Try using chipboard screws instead, maybe it works better?

Or just put up the skivor with sättlim.

It might be worth trying different types of drywall screws. When we installed renovation drywall at our place, this type of screw from Grabbers worked very well, tighter thread and double head seemed to help.

Adhesive paste is a nuisance. It requires copious amounts of glue.

Tile adhesive is a nuisance. You go through copious amounts of adhesive.

Aha!
Lucky that we didn't know that when we renovated the bathroom in the vacation house

Gypsum plaster that you spread with a notched trowel and then a few screws along the edges to hold it up while the gypsum plaster sets.

Thanks for the help. I'll try it when I finish the rest.

I think Biltema's drywall screws work well. Much much better than other cheap screws I've used anyway.

My experience is that it's better to screw in the screw with full speed on the screwdriver in one motion. If you don't manage to screw it in completely and tighten it a little extra afterwards, the result is worse. In other words, it’s important to have a bit of a feel to drive the screw to the right position the first time.

I used drywall screws with a slightly smaller head from Byggmax (Heco) and they have worked well. I had the same problem as you before I was recommended these screws.

Press harder with the screwdriver and ideally with your hand next to the screw to prevent the board from lifting off the surface while the screw is driven in. Alternatively, the surface might be so uneven (or soft) that the board does not make contact. When it looks like in the picture, the board hangs in the paper just because the gypsum is cracked. Spackling won't work well either since the board will move if pressed. The board must be intact and flush against the surface at the fastening points for it to be properly installed. Remove the screw and drive in a new one a bit away from the damage.

Chipboard screws don't work on gypsum because the head drills into the material and removes the paper that the screw should rest against.

Mounting adhesive, no. Pity the one who needs to remove the board in the future.
