Please adhere strictly to the instructions described on the following pages during application\u2013otherwise errors are virtually inevitable.<\/p>\n<\/div>\n\n\n\n

\n

The application of the system is basically quite simple. The potential for errors is often hidden in the details!<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n

\n

Consequence<\/strong><\/h3>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

Substrate not Q2.<\/p>\n<\/div>\n\n\n\n

\n

Risk of marking of substrate unevenness.<\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Not primed with DEKOZELL Isogrund.<\/p>\n<\/div>\n\n\n\n

\n

No clearly defined absorbency and adhesion of the substrate, therefore risk of delamination. The Isogrund protects the plasterboard during the drying time of the spray filler and also prevents the screw heads from rusting during the drying phase.<\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Adhesive bed thinner than 300g\/m\u00b2.<\/p>\n<\/div>\n\n\n\n

\n

No full-surface adhesion of the acoustic plaster base fleece, therefore risk of detachment or voids.<\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Acoustic plaster base fleece not bonded with DEKOZELL dispersion adhesive.<\/p>\n<\/div>\n\n\n\n

\n

Risk of detachment during drying of the final coating due to insufficient water resistance of the adhesive bond.<\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Acoustic fleece not pressed down with wallpapering spatula after application.<\/p>\n<\/div>\n\n\n\n

\n

No full-surface adhesion of the acoustic plaster base fleece, therefore risk of detachment.<\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Adhesive dried before laying the next track.<\/p>\n<\/div>\n\n\n\n

\n

Danger of marking out of steps, the final coating with acoustic spray filler only compensates slightly.<\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Acoustic spray filler applied too thinly or to very different thicknesses.<\/strong><\/p>\n<\/div>\n\n\n\n

\n

Risk of holes in the GK board showing through after sanding. As a remedy, a second coat is necessary.<\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

No polishing sanding with eccentric and 320 grit, only basic sanding with Flex Giraffe.<\/p>\n<\/div>\n\n\n\n

\n

Sanding marks, sanding grooves and uneven velvet sheen as a result of not polishing.<\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Screws not filled and not sealed with Isogrund.<\/p>\n<\/div>\n\n\n\n

\n

Formation of rust stains during drying. Remedy only possible by partially replacing the top coat.<\/p>\n<\/div>\n<\/div>\n\n\n\n

This list of errors does not claim to be complete (completeness on website). We generally recommend that inexperienced tradesmen set up a practice area or book a construction site training course.

Install perforated panels according to the manufacturer’s instructions and fill\/sand to Q2.<\/figcaption><\/figure>\n<\/div>\n\n\n\n
\n

Install perforated plasterboard ceiling according to manufacturer’s specifications Knauf or Rigips and pre-fill\/sand to Q2 and prime with deep primer all around at least the ceiling edge. In principle, any perforation can be laminated, but the use of maximum perforation 12\/25 is generally recommended from an acoustic point of view.<\/p>\n\n\n\n

Do not forget to place a mineral fiber mat as the actual sound absorber behind the perforated panel!<\/p>\n<\/div>\n<\/div>\n\n\n\n

so as not to tear away the dried Isogrund or dried adhesive at the very end and thus damage the still wet edge of the acoustic spray trowel.<\/figcaption><\/figure>\n<\/div>\n\n\n\n
\n

The final coating with the acoustic spray filler applies a layer thickness of approx. 5-6 mm when wet, which then shrinks to approx. 3 mm during drying. It has proven to be a good idea to apply a fabric adhesive tape (e.g. Tesa 4363, width 35 mm) approx. 5 mm below the ceiling before applying the insulating primer. The blue fabric tape will later form the final edge of the acoustic spray filler. So place this tape neatly!<\/strong><\/p>\n\n\n\n

The masking film for the wall can also be clamped under the blue fabric tape (e.g. masking film purple no. Secure).<\/p>\n\n\n\n

To ensure that the Isogrund and then the dispersion adhesive do not adversely bond with the blue fabric tape, we recommend overlapping this blue tape by a few millimeters with a weaker adhesive crepe tape or yellow grooved PVC tape:<\/p>\n\n\n\n
