Wet bending 

1. Put the cut-to-length Knauf Boards on a grid made of 

channels or similar with the side to be compressed on top and 

excessing the grid on the perimeters (so excess water can drip off). 

2. Perforate the board laterally and longitudinally with Spike Roller. 

3. Wet the board by spraying or with lambskin roller and let settle for 

a few minutes. Repeat process until excessive water drains. 

4. Lay board on precast molding device, fix with tape 

and let dry.

Construction and Application, Jointing, Surface Treatment 

Construction 

Knauf Ceilings as ceiling lining or suspended 

ceiling are fi xed to the basic ceiling with a rigid 

suspension. Knauf boards and factory or bent 

on site boards with parallel slotting or mitering 

are fi xed to a metal grid of lower and upper C 

channels (D112) or a fl ush grid of C channels 

(D113). 

Settlement joints have to be taken over into the 

construction of the suspended ceiling systems. 

Use control joints in the case of ceiling areas 

over approx. 15 m length, or for narrow ceiling 

spaces caused by a break of a wall. For strongly 

structured suspended ceilings additional movement 

joints may become necessary. 

D19 

Knauf C channels are delivered galvanized. This 

corrosion protective coating is suffi cient for indoor 

rooms, including bathrooms and kitchens 

in private housing. For other areas, e.g. under 

infl uence of outdoor air, additional corrosion protection 

is necessary (see DIN 18168-1 table 2). 

Application 

Grid 

● Rigid suspension with Universal Brackets/ Nonius 

Hanger/ Combo Hangers/ Nonius Stirrups 

with Nonius Hanger Top or Anchor Hanger. 

● Anchored on basic ceiling made of 

Wood: Use Knauf Drywall Screws (fl athead) 

FN 5.1 x 35 mm (used in accordance with 

Construction Supervisory Permit no. Z-9.1- 

251) 

Reinforced concrete: Knauf ceiling steel dowel 

(mounted in accordance with Construction 

Supervisory Permit no. Z-21.1-1519) 

Other building materials: anchors have to be 

permitted and standardized for the building 

material being used. 

● For the spacing of fi xings of the suspenders on 

the basic ceiling and the spacing of channels 

see tables D112/ D113 (TDS D11 Knauf Plattendecken). 

For Apertura Board Ceilings see 

TDS D12 (Knauf Acoustical Ceiling Systems). 

● Connect upper C channels with hangers and 

align them at the required suspension height. 

Connect lower C channels CD 60/27 to upper 

C channels with: Intersection Connectors, 

Clip for CD 60x27 or Daisy Chain Clip. Other 

channel connectors: Multi Connector or Universal 

Connector 60/27. 

Cladding 

Cross mounting of Knauf boards to lower C 

channels, displacement of jointings at least 400 

mm ensuring that end joints bear on C channels. 

Start fastening of Knauf boards either in 

the middle or at a corner in order to prevent upsetting 

deformation. 

Press boards fi rmly on to the grid during screw 

attachment. 

Additional loads 

● Single loads applied directly to the cladding 

must not exceed 0,06 kN per spacing of lower 

channels and meter. 

● Apart from that, additional loads have to be 

considered for the calculation of the dead load 

of the suspended ceiling if they are borne by 

the ceilings subconstruction. The loads are to 

be included when determining the load class 

from the table on page 2 of TDS D11. 

● Other additional loads have to be applied directly 

to the basic ceiling. 

Knauf Drywall Screws for the fixing of Knauf boards onto metal channels with a thickness of d = 0.6 mm 

Thickness of boards Knauf Drywall Screws (DIN 18182-2) Spacing of screws (DIN 18181) 

up to 15 mm TN 3.5 x 25 mm 170 mm 

18 to 25 mm TN 3.5 x 35 mm 170 mm 

2 x 12.5 mm TN 3.5 x 25 mm + TN 3.5 x 35 mm 170 mm 

Jointing 

Fill in joints with Knauf Unifl ott without using 

tape. If using tape, fi ll in with Knauf Fugenfüller 

Leicht or with Ames machine and Knauf Jointfi 

ller-Super. 

Cover all screw heads as well. For double layer 

cladding, fi ll in joints of fi rst layer, smooth joints 

of second layer. 

Recommendation: Fill in and tape cut edges of 

visible layers no matter which fi lling material is 

used. 

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. Joints 

should be fi lled at a minimum temperature of 

10°C. In case of mastic asphalt screed, fi ll in 

joints after screed has been applied. 

Surface Treatment 

Use a primer on Knauf Boards before coating or 

painting them. Ensure that the primer and the 

coat or paint are compatible. The following coats 

can be used to cover Knauf Boards: 

● Coats: Washable and abrasion-proof emulsion 

paint, multicolored (rainbow) emulsion, oil 

paint, matte-fi nish lacquer, alkyd resin paint, 

polymer resin paint, PUR lacquer, or epoxybased 

lacquer, according to intended use or 

as required. 

● Wall Papers: paper-, textile and synthetic wall 

papers. Use only adhesives made of cellulose 

according to „Merkblatt Nr. 16, Technische 

Richtlinien für Tapezier- und Klebearbeiten“, 

Frankfurt/Main 2002, released by Bundesausschuss 

Farbe und Sachwertschutz. 

After wallpapering of paper and fi ber glass 

wallpapers quick drying must be assured 

through adequate airing. 

● Alkaline coats such as lime, water glass colors 

and silicate-based paints are unsuitable 

for gypsum board surfaces. 

● Silicate-based emulsion paints may be used 

after referring to the manufacturer’s recommendations 

and following the stipulated guidelines 

closely. 

Gypsum board surfaces that have constantly 

been exposed to light without any protection can 

develop yellowing agents that show up despite a 

coat of paint. Therefore a trial coat is recommended 

that will extend across several boards including 

all joints. Yellowing can, however, be successfully 

avoided only by using a special shielding 

primer.
