Plasterboard
As can be said, whether the plasterboards can be used in rooms with high air humidity, no risk of damage?
Building plasterboards are suitable for rooms with high air humidity, type B, impregnated (abbreviation GKBI). These plates are printed in blue on green cardboard.
What tests should be carried out on the substrate made of built-in plasterboards before applying the coating? How can possible damage to the hob be identified??
Required substrate tests and damage identification features:
| Substrate research | Damage recognition |
| Inadequate fastening | the plates move when pressed |
| No reinforcement at the board joints | visual; bald forms between the edges of the plates |
| Uneven filling of joints | visual; with incidental lighting |
| Surface damage | visual |
| Moisture | visual; based on the color of the plates |
| Dirty | visual |
| The presence of coloring materials | visual; on the basis of the yellow tint |
Please draw various shapes of plasterboard edges and define the scope of application of these boards.
