MAKING A PLASTERBOARD WALL IN 10 MOVES:

1. First of all, we create a metal perimeter structure on which we will then fix the plasterboard sheets:

- draw the guidelines with a pencil remembering to mark also the position of the doorway if provided. On the ground interruption of the rail, position two vertical profiles and a crosspiece at the top to indicate the presence of the door.

- check the exact match of the traces on the ceiling and on the ground with a lead wire (or with the aid of a laser) so that the wall is perfectly straight.

- apply adhesive insulation strips on the back of the profiles (to avoid thermal and acoustic bridges) before fixing them to the floor, wall and ceiling.

- fix the metal structure to the ground and the ceiling with expansion plugs at a distance of about 60 cm from each other.

Note: for the profile on the ground we can proceed with fixing with a double-sided adhesive tape if we do not want to damage the underlying floor.

2. Now let's go to build our metal mesh by inserting vertical profiles (uprights) inside those previously placed on the perimeter (guides):

- insert the uprights in the guides at a distance of 60 cm, check with a magnetic level with bubble vials (or with the aid of a laser) that the uprights are perfectly vertical so as to obtain a lead wall.

Note: the uprights should all be directed to the same side.

- only after having established the exact position, fix the uprights to the guides with suitable flat head self-drilling screws (teks screws) or make use of a manual punching machine for 7mm sheet profiles necessary to assemble the two metal profiles by punching.

- the first and last uprights must be fixed to any side walls with expansion bolts at a distance of about 60 cm from each other, taking care to fasten one close to the floor and one close to the ceiling.

3. Now we start to fix the plasterboard sheets to the metal structure:

- ground some 1 cm spacers on which we will support the plasterboard.

- then position the plate in contact with the structure.

- fix the first plasterboard plate with black phosphate self-tapping screws and screwdriver with torque adjustment or depth limiter, making sure that the distance between the screws is about 30 cm from each other and about 1 cm from the edge of the slab same.

- continue in this way along the entire length of the metal structure created, so as to uniformly fill the wall.

Note: if the last slab is longer than the metal structure, cut it with a professional cutter and file any edges with a file planer so that the edge of the slab is perfectly in line with the metal profile.

- now arrange, if necessary, any acoustic or thermal insulating panels inside the concave part of the metal structure and in the eventuality carefully cover the entire surface of the wall to obtain a performing technical result.

- the interspace in the wall is ideal for installing, moreover, systems and piping. Any openings for sockets and switches can be made with a drill bit.

4. We carry out the same operation from the opposite side of the partition wall following the instructions in point 3.

Note: the insulating material must remain in the middle.

5. Now let's move on to the grouting phase:

- fill the edges on the ceiling and on the floor, fill the joints of the slabs and the heads of the screws.

- after drying, sand the whole with abrasive paper and try to make the surface uniform.

6. Apply a strip of self-adhesive mesh tape over the entire length of the joint on the horizontal and vertical joints.

7. On top of the self-adhesive mesh tape strip, apply a little (small amount) of plastic wall filler. We have to spread it out well with a spatula.

8. With the spatula we pass a little more plaster, trying to equalize everything and make the surface perfectly uniform.

9. On the surface we spend one hour a slightly moist sponge.

10. Let dry and then shave the small imperfections with the trowel.

Here is our plasterboard wall, that is to say an element of separation within a large environment that we want to separate in two environments.
