ᐅ Which type of filler or joint compound should be used?

Hello everyone,

We need to get joint compound for our painter now. The base materials are gypsum fiberboard walls and gypsum plasterboard ceilings.

He doesn’t have a strong brand preference, normally he uses Knauf UniFlott, which he says has inconsistent quality. In terms of application, he prefers Gima joint filler. There is also Rigips Vario, which can be used without reinforcement tape, and Rigips Super joint filler, which requires reinforcement tape. There is, of course, a price difference:

Knauf 33 EUR
Gima 32 EUR
Vario 38 EUR
Super 22 EUR per 25 kg (55 lb) bag

Are there any significant quality differences here? In another forum, I read that one should look for a fiber-reinforced product to help prevent cracking. Any opinions?

If he prefers Gima, then just buy Gima... If you choose something else and then something doesn't fit, you'll only hear "I suggested Gima after all."

Do not skip the strips of fiberglass mesh. Painter's filler: often Sto fill in

• 15kg (33 lbs) 23.00
• organically modified
• fiber reinforced
• easy to sand
• quick to recoat

I would completely agree with Lumpi_LE here; if you are already providing him with the materials and he mentions one he normally works with, it would be better to buy that as well. That way, you will be on the safe side.

Basically, I had planned to get the Gima as well. Unfortunately, there is hardly any information online about its quality or crack resistance. He only mentioned that the Gima is easy to work with, but there is no long-term experience.

I am also considering the Rigips product for 22 EUR...

Absolutely clear: the craftsman gets the materials he requests. Period.

Otherwise, I am happy to work with Pufas filler. For the finish, Alsecco ready-mixed filler from the tub.
