Grid for plaster: yesterday and today
Wall plaster has been used for a long time. Confirmation to that is found by scientists from all over the world in the excavation of traces of human presence, which date back to the end of a past era. And already very long time for qualitative performance of plaster works the reinforcement is used - plaster of walls on a grid which in advance is fastened on a processed surface.
Today, reinforcement is most often performed by means of a special mesh - metal or polyurethane, and earlier for this purpose shingles were used( for internal and external surfaces) or sometimes - a homemade wire frame. Grid is fastened with glue, screws, screws or other similar devices.
Types of mesh for plastering
The following types of nets are distinguished:
- masonry - plastic, made of polymer substance, with a cell size of 5x5 mm, is used for brickwork;
- universal small - made of polyurethane material, with a cell size of 6x6 mm, is excellent for reinforcing both plaster mixes and finishing. Convenient, widely functional, allows you to work any area;
- universal - the same in structure as the previous one, but with a cell size of 13x15 mm;
- is a large station wagon - this grid differs in the size of the cell - 22x35 mm, it is used for reinforcing over large areas( warehouses, facades of production departments and other large-sized structures);
- glass mesh - consists of specially treated fiberglass fibers, with a cell size of 5x5.It is characterized by high resistance to chemical and thermal influences, heavy-duty, capable of carrying large loads. The use of this base for reinforcement is very wide and has almost no limits;
- plurima is a biaxially oriented plaster mesh made on the basis of polypropylene, with a cell size of 5x6 mm. It is characterized by lightness and chemical inertness, it is used both for internal and external finishing works;
- Armaflex is a polypropylene mesh, with reinforced knots and a cell size of 12x15 mm. Ultra-strong, excellent for use in places with high load of plaster layer;
- sintoflekas - a mesh consisting of polypropylene, with a cell size of 12x14 and 22x35 mm. It is light and inert to the effects of chemicals. Suitable for exterior and interior decoration;
- steel - is based on steel rods, welded in knots, with a wide range of cell sizes. The metal mesh under the plaster perfectly holds the load, but it is applicable only for interior finishing, since unprotected steel does not tolerate atmospheric precipitation;
- galvanized - mesh, binding of galvanized rods, welded in knots, with a diverse cell size. Excellent for both indoor and outdoor work, it is distinguished by its high strength and high durability, it is used practically in any conditions.
Wall plaster on the
grid Depending on the layer you are applying( spray or cover), the plastic mesh for plaster or metal can be fixed in different ways. The lower layer of plaster is reinforced with the selected mesh on top of the thickness of the solution applied, slightly drowning it.
Ideally, for the application of the last - covering or decorative layer, the reinforcement is first secured with special devices to the dry surface. But when processing small areas as a fastener can make itself a solution for plastering the walls. In this case, it is first applied first to fix the mesh. And after - the required thickness of the plaster layer is uniformly spread over the whole surface.
Using a grid can greatly facilitate the finishing work, and the choice of a particular type depends on the specifics of the work and your solvency.
