Anyone have tips on anchors that have worked well to attach baseboards to plastered träullit (a rather thin layer of plaster)? The old baseboards were attached with regular yellow plastic anchors, which didn't work so well.
You need an adhesive that grips immediately, such as casco Xtremefix. However, you will probably still need to fasten with screws and plugs until the adhesive has dried.
No plug bites into träulit, how thick is the träuliten, the problem is that a plug will always follow around if it doesn't have something holding it back, and the träuliten is fragile with lots of air in it + wood fiber strands. Gluing is the same as having studs on the floor between the walls that hold the baseboard in place, any gaps between the wall and baseboard are removed with latex caulk, the painter's best friend.
No plug works in wood wool cement board, how thick is the wood wool cement board, the problem is that a plug always wants to turn unless it has something to hold it in place, and the wood wool cement board is crumbly with lots of air in it + wood fiber strands.

It's probably that bad. The wood wool cement board and the plaster build up about 35-40mm from the concrete hollow block. Might have to trust that the plug grips sufficiently in the plaster. I'm testing with Fischer Duopower, which seems the most promising unless anyone has another super plug to recommend.

Maybe glue the plugs? Some form of two-component adhesive or chemical anchor. But it might tear out the next "layer" of the wood wool cement board?
Might help somewhat. It feels like I won't get away from using glue in some way.
I have weak lime plaster in parts of the house's basement. A bit of the same problem. The solution here is a hole, smear in Husfix, and insert a regular plastic plug. The next day, it's possible to screw.

Do you need many fasteners, there are in the grabbers assortment 4.5 X70 mm and some other long slim ones, you'll need to get a 100 mm carbide drill bit and use a red plug, then I think you'll manage. Search for Wood screw 5X70 mm and you'll find plenty of options to choose from.

Good backup if it doesn't work with just the plug. Need to buy a small piping bag so I can fill in some cavities in the träullit

About 50 attachment points might be needed, but it depends on if it grips or not . I assume you mean that the screws/plugs should be long enough to grip in the concrete block? Then I might need longer plugs than red plugs unless I push them in a bit into the wall.
Thin screw and double red plug usually attach quite well. Then you can countersink in the baseboard. Claes's idea of filling is also an option. It's a bit stubborn to get it there, though. But you have to be persistent.
When I attached building boards to Träullit, I drilled straight through the Träullit and into the concrete behind. Then I hammered in long nail plugs so that the expanding part ended up in the concrete.
Of course, my Träullit wasn't that thick.
