The process of alignment of ceilings and walls with drywall (GLC) is simple, fast and inexpensive. What exactly the material is suitable for finishing wet premises, how to protect it from moisture and arrange the finishing finish - we tell in the article.
The wet is called the premises if the humidity of the air in them periodically exceeds 60%. These are kitchens, showers and bathrooms, winter gardens, etc. In them, the ceiling, walls and floors are often becoming a condensate fallout area or directly in contact with water.
The finish of these surfaces is unstable to water materials fraught with the occurrence of colonies of fungi and mold and premature spill. Therefore, for the leveling of ceilings and walls, the construction of partitions as the basis for decorative finishing and fixing heavy items is used exclusively sheets of moisture-resistant drywall (GVLV).
Plasterboard Waterproof Knauf
Features of moisture resistant plasterboard
Unlike the usual, whose two layers of cardboard has a core from a gypsum sensitive gypsum, special substances that reduce water absorption are introduced into the moisture resistant GKK. Visually to distinguish moisture-resistant material easily on green sheets of sheets. However, there is an alternative to moisture-resistant sheets of drywall, the truth is more expensive. These are cement-fibrous panels, sometimes they are called fibro-cement. They are 80-90% consisting of cement, in which reinforcing fibers and mineral aggregates are present. Fasten the panels as well as GLC, to a metal, less often a wooden frame.
In regions with high humidity, experts recommend using moisture-resistant plasterboard even in rooms with dry and normal humidity regimes
Additional Protection of HCL
After the ceiling and walls are covered with sheets, these surfaces are covered with ground penetration soil, which strengthens them and reduces absorbing ability. Plots near the shells, baths and shower, as well as the bottom of the walls, in a word, everything that can contact with sprinkled water is necessarily treated with waterproofing mastic.
Places of water supply and sewage pipes, angles, in addition to waterproofing, are additionally sampled with sealing ribbons, rings, etc., to make them maximum protected from water exposure. The joints of the walls, as well as walls and gears, are filled with sanitary sealant, which forms a waterproof and at the same time an elastic compound capable of withstanding minor movements of moisture-resistant plasterboard sheets.
Plasterboard List (GLC) Moisture Resistant
Features of styling finishing in GKL
Ceramic tiles are most often used as cladding walls of the bathroom. It is obvious that the plasterboard cover should withstand the mass of the tile itself and the cement tile glue layer, that is, being durable and stable. The most reliable in this case is the sheath of two layers of GVLV. At the same time, vertical and horizontal sheets of sheets should not coincide. The optimal distance between them is from 40 to 60 cm. In addition, they should not tightly lay down to the surface of the floor or ceiling, and be at a short distance from them (5-10 mm). To eliminate the appearance of internal stresses, the sheets are fixed sequentially from the center of the part to the edges or from one edge to another.
The finished tile facing does not give to penetrate the water inside to the carrying structures. To the one who does not want to sneak the walls of the bathroom with ceramics, but prefers decorative plaster or paint, they will need materials that will not hurt high humidity, and which will become an insurmountable obstacle on the way of water to plasterboard. For example, special paint with waterproofing.
