Drywall Installation Guide
Drywall Installation Guide
- Installation of Profiles. The upper and lower rails will be made with steel nails (1” type impact nail) every 60 cm maximum, the first and last fixing must be at a maximum distance from the edge of 5 cm. The Uprights must always maintain the same direction, and must be cut between 8 and 10 mm shorter than the internal distance between channels.
- Installation of Plates. It is recommended to leave an upper and lower dilation in the plates of 1 cm. At the top, as an expansion of the structure (slab or roof). At the bottom, to prevent the plate from absorbing moisture through capillarity.
- A piece of the same plate can be cut as a separating element.
- The plates must be installed butt to each other (without distance).
- Fixing the plates. The plates will be fixed with 6 x 1” screws, depending on whether they are galvanized steel or wood profiles. The appropriate length will be the one that extends 10mm through the metal or 6 1/2 inches into the wood.
3.1 Screw installation. The screws must enter perpendicular to the plane of the plate, being slightly recessed in the paper on the visible side of the cardboard gypsum board. If the cardboard breaks, the screw must be replaced by changing it in another nearby place.
The length of the screw may vary depending on the thickness of the plate or if it is more than one. It is recommended that the distance between screws be:
- 25 to 30 cm on the modulation or intermediate uprights.
- 15 cm at the joints of the plates and in a locked shape (zig-zag).
3.2 Important considerations. Missing plate screws can lead to lead or septum line problems; It can also cause mechanical, acoustic, fire resistance problems and even failures in the treatment of joints.
- Union between plates. The plates have a longitudinal recess (long side), which facilitates the treatment of joints on them. It is not recommended to join 2 plates with different edges, this type of union can cause problems in the treatment of joints.
- Meeting between partitions.
- Detail meeting in L:
- T meeting:
- Execution of lintels. On the lintels, the joints of the plasterboard boards should never coincide with the door and/or window frames, since it is precisely at the vertices or corners of the frames that the maximum efforts are concentrated and there is a risk of cracks. in unions. It is recommended in these areas to cut the plates in an "L" or shoulder shape.
- Treatment of Joints For the treatment of joints and protection of edges, the use of strips or corner pieces is recommended, which are always applied with a base putty for joints (in no case should they be done with plaster). There are basically two types of strips: The joint-type self-adhesive fiberglass strip and the special micro-perforated cellulose strip. The combination most used by builders and masters is the Fiberglass strip together with the Gyplac Base Putty. This treatment must be carried out by applying a Gyplac joint adhesive before the putty (Figure 1). The illustration shows the treatment with a paper strip (Figure 2). It is extremely important to generate a filler between the recess of the plates and the tape, otherwise the material (putty) remains working in the air and the risk of sura is high. Figure 2 illustrates the layers of putty that must be present for good joint treatment. First a layer of filler, then the strip and two finishing coats.
- To carry out the correct collection of plates in the field, it must be on a dry, level surface and also maintain the same palletizing system that is sent from the factory. It is recommended to collect a maximum of two pallets in height, protected from humidity and humidity. excessive sun exposure.
- To avoid deformation of the plates on the pallet, the maximum number of units is:
- Stack on plasterboard strips of a uniform height or on a pallet.
- For plates with a length less than 240 cm, the use of at least 5 strips is recommended, as shown in the figure (Figure 3). For a length greater than 240 cm, use 6 to 8 straps as shown in the figure (Figure 4).
- Transfer and Handling. If the plates are moved manually, they must be carried edge-on between two people.
