When renovating a building or room, the walls are initially covered with a layer of plaster. This is normally the job of a trained specialist. The disadvantage this has is that a large amount of moisture enters the place; therefore, taking a few weeks to dry out completely.
The subsequent insertion of solid partitions and attic extensions cause similar problems. Bricks must be placed and plastered. Moisture is also formed and this must be removed, before placing wallpaper or tiles.
In order to avoid the problem of excess water, drywall interior fitting is recommended (water is only added to the mixing material and the mix binder).
With this alternative to classic extension techniques, plasterboards are attached to wooden or metal sub-constructions, making it easy for the DIY enthusiasts.
