Knauf TRIAS
Gypsum compound for filling joints of drywall systems by hand application
Product description
Fields of application
Properties
Knauf TRIAS is a special gypsum-based, synthetic-tempered, powdery material, adjusted with
additives for its fields of application.
Joint filler type 4B acc. to EN 13963.
Knauf TRIAS is used for filling of joints by hand
application for
■ gypsum boards or composite boards with HRK
(half-rounded edge) or HRAK (half-rounded tapered edge), without joint tape on paper covered edges,
■ gypsum boards with AK (tapered edge, particularly with Knauf Horizonboard) in connection with joint tape, preferably Knauf Joint Tape
Kurt,
■ perforated gypsum boards with edge type SK
(cut edge) or FF, e. g. Knauf Cleaneo® Acoustic boards.
Colour and absorptivity of Knauf TRIAS comply
with the characteristics of the gypsum board paper liner after drying, providing low-contrast surfaces, e. g. for paint coats or fleece wallpaper.
■ Extremely low drying shrinkage

Application
Coats and linings
Substrate
Knauf Boards should be applied tightly on a steady
substructure, clean and with dust-free joints. Prime
edges of Knauf Cleaneo Acoustic SK Boards.
Mixing
Sprinkle Knauf TRIAS in clean water up to close
below water line (5 kg in approx. 2.4 l water) and
mix immediately with slowly running mortar mixer
(min. cage diameter 80 mm) or by hand with trowel, without any further additives to a creamy, firm
compound. Use clean mixing vessel and tools.
Application (non-perforated gypsum boards)
Apply in usually two operations, depending on required surface quality level. Fill joints fully in the
first operation. Create a smooth and levelled transition to the board surface in the second operation
with Trowel or Wide Spatula. Fill screw heads as
well. Sand after complete drying, e. g. with Knauf
Abranet Rasp Mesh. Clean tools and pails after
use.
Application (perforated gypsum boards)
See installation guides Knauf Cleaneo® Acoustic
SK (TRO14.de) and Knauf Cleaneo Acoustic FF
(TRO14FF.de).
®
Application time
Hardening starts approx. 45 minutes after sprinkling (at 20 °C). At low temperatures a shorter application time can be expected, while at high temperatures a longer application time occurs. Application time is shortened if unclean pails and tools
are used. Do not use hardened material and do
not try to fluidize it by adding water or stirring to
make it processible again.
Application temperature/climate
Filling and covering of joints should only take
place after the boards have been allowed to rest
in the given humidity and temperature zones, and
no more longitudinal changes can be expected, i.
e. expansion or contraction. In case of mastic asphalt, gypsum and cement screed, fill joints after
screed has been applied. Do not fill joints at air
and surface temperatures below 10 °C. Notes of
the Code of Practice no. 1 “Baustellenbedingungen” of the BVG (IGG) are to be observed.
The filled surface should be dust-free.
Prime if necessary for special requirements of the
following coat or lining (e. g. wallpaper primer, interior silicate paint), acc. to BVG (IGG) Code of
practice no. 6. "Vorbehandlung von Trockenbauflächen aus Gipsplatten zur weitergehenden Oberflächenbeschichtung bzw. –bekleidung".
Ensure that the primer and the coat or paint or lining are compatible.
In case of wallpaper lining a primer that allows an
easier removal of wallpaper for redecoration is
recommended. A sealing primer of Knauf Flächendicht is required for covering splash water areas
with tiles.
After wallpapering with paper and fibre glass wallpapers or the application of resin / cellulose plasters, quick drying must be ensured through adequate airing.
