Recommendations for the use of magnesite board «MAGNECO».
Magnesite board should be stored in a dry place with sufficient ventilation. In cases when a specific time magnesite board is stored in the open air, for example, on objects, we recommend you to keep the boards under any open shed to protect from direct exposure to moisture. If the boards are wet, they must be dried before installation.
Immediately prior to installation the magnesite boards must be primed from the front and inner sides, abutting end of the magnesite board with primer coat of deep penetration twice.
When mounting magnesite board it should be taken into account the water vapour permeability properties of the material. To this end, during finishing works on one side of magnesite board, using material which prevents absorption of moisture (ceramic tile, vapour-proof paints, varnishes, wallpaper, etc.), the other side of the magnesite board must be given similar properties. Therefore, it is necessary to treat the opposite side of the board with a vapour barrier materials (hydrophobisators, varnishes, paints, etc.), or by priming with the method of multiple priming to form a film on the surface of a magnesium board.
During the internal work, the installation of magnesite board should be carried out during the finishing works (in winter only with heating), before finish flooring, whereupon all the “wet” processes must be completed and arrangement of plumbing systems and electro-purpose work has to be carried out, while meeting the normal humidity regime. The temperature in the premises, where it is conducted an appropriate work, should be not lower than + 10 ° C. Magnesite board before installation must be appropriately adapted directly in the premises.
In outdoor applications magnesite board must be acclimatized before installation. The ambient temperature and the material should be not lower than + 5 ° C.
Magnesite board is quite easily cut using a usual manual (knife, hacksaw, etc.) or electric (angle grinder, jigsaw, circular saw) tools. Cutting with a knife is absolutely identical to cutting of gypsum board. When cutting the magnesite boards using electrical tools it should be used tools with protection against dust and the presence of diamond cutting edges. Chamfer from the plate ends can be easily removed with the help of the planer and sander.
Magnesite board can be mounted on metal or wooden profile systems, as well as on the glue with additional “umbrellas” fastening.
Firring of profile system is calculated at a pitch of stub not more than 450 mm, taking into account the size, thickness of the board and the requirements for stiffness to the finished construction. There is a rule: the thinner is the board, than, respectively, the less step of firring is used.
If magnesite board is used as the base for the floor (floor batten) or base when gluing tiles, stone and ceilings boardering, the firring step is reduced to 300×300 mm.
For mounting the magnesite board to profile system it is used the self-tapping trim-head screws (with notches on the back of the head). The presence of anti-corrosion coating on the screws is a prerequisite. The screws are screwed to magnesite board at a distance of 10-15 mm from the edge of the board at a pitch of about 15-20 cm. When using screws without the presence of notches on the back of the head, it should be done spotting in places of their installation.
Between the boards it is necessary to leave a gap of about 2 mm (for internal work) and 3-4 mm in outdoor application. The resulting joints are sealed with magnesite filler, with additional reinforcement with painting edging tape.
All work related to the process filling (sealing of joints and places of screws fixing, finish a coat of plaster to a true surface) is better to be done with magnesite filler, produced by Company Magnesite Poland, observing the conditions related to operational.
Painting of magnesite board should be performed with water-dispersible paint that will not interfere with the free absorption and expulsion of moisture.
