Plasterboard joint filling without tape

murphaph

I have the "shell handover" of our house here in Germany tomorrow. It's my responsibility to joint the plasterboard in the whole house. The house builder recommends a product called Knauf Uniflott + Knauf Uniflott Finish.

Uniflott (and Variogips by Lafarge and presumably some other products) has a fibre mixed in with the powder and you mix it up and apply flush with the joint with NO TAPE. It will pull in a bit as it goes off and will be below the level of the joint when dry. 30mins after application you scrape off any excess with the trowel/knife. You then apply the Finish (which comes ready mixed in 20kg tubs) to this and sand when dry (apparently if done properly there is very little sanding to do).

I tried googling for something similar in the English speaking world, but it always seems that taping (either paper or self adhesive mesh) is always recommended and maybe these "reinforced" joint filling compounds don't even exist, or do they?

Skim coating plasterboard is more or less unheard of here. It's all tape and joint or "tapeless" jointing as above. Just curious if anyone knows of the "tapeless" jointing practice in Ireland?

Well its a long time since I was on a site so have never come across it. But If it were me I'd run scrim tape down joints just to be sure. Scrim tape is fairly cheap and it takes not time to run it down a joint and onto next one. You'd scrim a whole house in a couple of hours.

ive never liked 'tape and fill' as a finish.. it ALWAYS exposes a line after a couple of years, especially on a TF build.

I've never used the stuff you mentioned but as another poster said its cheap to buy a few rolls of sticky scrim and put it on before filling out the joints .
Years ago they used to leave a gap the thickness of a 50 pence piece between the slabs and "cork " the joints without using scrim - trowel the skim up into and out the back of the slabs so the joint was held together like that before skimming . They still used to scrim the angles with the old horse hair scrim .
You will get the hang of not putting on too much finishing compound after you've sanded down a few strong joints !
Would be worth getting a plasterer to do it ? It will be a finish you'll be looking at for a while if it doesn't turn out well

Are the joints in the board rebated to allow the scrim or tape layer?
