Properly pasted wallpaper wallpaper - a real art. And to properly prepare these very walls is an even more complicated process, requiring skill and certain knowledge. If you paste wallpaper on plasterboard without puttying , almost certainly there will be problems: the color of gypsum boards will necessarily appear, when you dismantle it you will spoil it and have to change it. Putty plasterboard under the wallpaper process is consistent and long, but it's quite realistic to master it.
Handling of drywall before wallpapering
- Preparing gypsum cardboard for wallpapering occurs in several stages. First, the surface is primed, then the joints are worked and reinforced, then the whole surface is plastered like a normal wall in three sets.
- Primer for gypsum cardboard under the wallpaper is best applied with a soft roller or a very wide brush. Make sure that the whole surface is evenly worked.
- It is also important than priming drywall under the wallpaper. For the processing of drywall we use acrylic primer, as it protects against the fungus, and the adhesion to the putty improves.
- When puttying gypsum cardboard for wallpaper, we need two different spatulas: it is convenient to take a solution more narrow, and apply it to the wall wide.
- It is very important to correctly prepare the seams between the drywall sheets under the wallpaper, since it is in these places that cracks are usually formed. First, we apply the layer of the mixture to the joint as thickly as possible. Then remove the excess (like cut) and attach a special reinforcing tape. It seems to be pushed into the mix of putty and left to dry completely. Then another layer of the mixture is applied from above.
- In addition to the processing of drywall before gluing the wallpaper, you should take care of the fasteners. All the heads of the screws are painted with paint, which will protect the fasteners from rust and prolong the service life.
- After such a preparatory finish, you can proceed to putty the entire surface. The first layer is applied with a mixture with a coarse fraction. This is the starting coat, it is applied in two layers. Next, you should apply a mixture with smaller fractions, it will be the finish.
- To level the surface and get a finished look, the surface must be sanded. In this case, we grind very carefully, so as not to remove the excess, as it will be necessary to apply a layer of the mixture anew. For there is a special device.
- Preparing gypsum cardboard for wallpapering is completed and now you can start decorating the wall.
