Manual of gluing cardboard-gypsum panel

The surface must be solid and all binding processes must be completed, dry, free from any grease, old paint coatings, loose plaster particles and dust, free from any biological corrosion.
In order to uniform the surface absorptiveness it’s necessary to prime the whole surface by using Universal Polymer Primer ACRYL-PUTZ® or Deep-penetrating Polymer Primer ACRYL-PUTZ®, and in the event of smooth concrete surface use - PA 10 FOVEO TECH Primer.
Preparation of cardboard-gypsum panels must be commenced by cutting them to the height of the wall and diminishing them of 15 mm – to provide proper space between the floor and the ceiling.
Before commencing to glue the panels it’s necessary to complete all floor works and electric works. It’s necessary to cut out all kinds of wholes for electric sockets or lamps, for example.
Prepare the Gypsum based adhesive ACRYL-PUTZ® in accordance with the manual displayed on the container. It’s worth paying attention so that the ready adhesive is used within 1 hour, and each new adhesive mixture must be prepared by using clean tools and containers.
Gluing must be carried out in temperature between +5 0C and +30 0C with the use of stainless trowel, brick trowel or putty knife.
Apply adhesive upon the surface of the panel in patches of 2 cm thickness and around 10 cm diameter and keep the distance between them from 30 to 40 cm, as well as a few spread patches along the edge.
The panel must be put against the wall and press slightly by using floating rules of 1 or 2 m height. Leave around 2mm space between the panels and 5 mm between the panel and the ceiling and 10mm between the panel and the floor. They will enable the air to circulate and as a result the adhesive will bind properly.
In order to put the panel upright it is necessary to take advantage of a contour line against the panel surface. Time necessary to adjust some corrections amounts to 10 minutes. Another panel must be glued after 15 minutes.
Before the final stage of binding it’s necessary to control the position of the panels on the wall by using a contour line.
Surface of panels neighbouring with windows, was basins, chimney etc. must be covered in whole and not only in patches.
In the event of surfaces of significant roughness, exceeding 20mm it’s recommended to level the difference by 10 cm wide gluing stripes made of cardboard-gypsum panels. The stripes must be glued both vertically and horizontally every 60 cm.
After full binding we can commence to carry out pointing of cardboard-gypsum panels by using the following:
- Without the use of tape - Special patching mortar ACRYL-PUTZ® for pointing of cardboard-gypsum panels
- With the use of tape or nonwoven interlinings – Special patching mortar ACRYL-PUTZ®.
