How to lay the plasterboard for outdoors

The installation of outdoor plasterboard provides the same laying technique as for the classic plasterboard.

Obviously there are some tricks to follow to carry out a work in accordance with that has no unpleasant surprises with the passage of time.

1. First of all, you will have to create the classic structure on which the fiber cement slabs will be fixed.

NB: The metal profiles must be fixed according to a very precise scheme dictated by the manufacturers and must necessarily be in "Aluzink" or have at least one treatment that makes them resistant to external corrosive agents.

2. The cement-based slabs must be fixed to the structure previously created using special screws with "Ruspert" treatment that make them suitable for outdoor use.

NB: the assembly of the slabs must be done by strategically positioning them and creating expansion joints that allow them to "accommodate" the physiological movement due to the thermal expansion of the profiles. In fact the latter with the heat of the sun tend to increase their volume and, at low temperatures, on the contrary, they may undergo shrinkage. This "accordion" movement should be favored otherwise it would result in slabs screwed to the structure of non-repairable tears.

3. The slabs must be "joined" to each other by means of a special fiberglass mesh for joint covers.

Note: the joint cover net must be made of alkali-resistant fiberglass.

4. The constructed façade must be fortified by an armor composed of a fiberglass mesh that will be subsequently shaved to make it uniform.

NB: the fiberglass mesh is commercially available in rolls of 1.00 m in height and 50.00 m in length with a tight 4mm mesh for 4mm. At the ends of the roll there are usually lines that indicate where the net is to be surmounted (or superimposed).

However, for the sake of calculation, many operators prefer the 1.10 m high network.

5. To complete the work it is possible to finish the facade with an external decorative element (marble, tiles, ...) or simply with a quartz or a painting.
