Fiberglass masking net is used mainly during puttying. It is necessary to prevent shedding of building compounds at the joints of walls with door and window frames, ceiling and floor, etc.
Painting grid (serpyanka) with a 2x2mm cell is indispensable in construction work for closing cracks in ceilings, joints of drywall, fiberboard, particleboard, etc. This reinforcing material is designed to improve the quality characteristics of the processed surface. It protects walls not only from mechanical damage, but also from technological defects and even temperature changes.
The paint net has the same properties as all other similar special building materials. It is made of fiberglass, which is bound and additionally impregnated with a special substance that is resistant to alkaline conditions. Such a mesh is necessary to improve the adhesion of finishing materials, well accepts the load, contributes to increased wear resistance of the surface. It is not flammable, non-flammable, resistant to frost, non-toxic, environmentally friendly. However, in order to perform its functions, it must be properly placed. It should be located between the layers of the mortar, and not between the surface and the putty (plaster).
Depending on the size of the cells, the masking grid is used in construction for different purposes. Also, its specifications may vary to some extent. Outwardly, it resembles gauze. When carrying out work inside buildings or outside, it is most often a reinforcing element. If necessary, it can also be used for other purposes: when plastering walls, installing a thermal insulation system, laying tiles, in an external protective layer. The mesh can significantly increase the strength of the treated surface and make it more resistant to destruction. Another plus of this material is that building mixtures on top of it lie smoother.
A masking grid is also used to decorate window and door openings, during decorative and restoration work, as well as when leveling bulk floors. It is very easy to use: you just need to put it on glue (for example, PVA or any other adhesive mixture) and stretch it on any surface, then apply plaster or other building mixture on top.
The most important indicator of mesh quality is the tensile strength coefficient. The cell sizes are quite small and amount to 2x2 mm. This is necessary for the strength of the reinforced mortar (putty) and for other types of work in which a paint net is used.
You can buy it today in absolutely any hardware store or order it in an online store with delivery. You need to choose the material depending on the base and reinforcement. Most often, a mesh is purchased for protective, restoration and decorative wall coverings, puttying , strengthening ceilings and walls, joints in slabs, facade insulation works , also for floor reinforcement or for laying a water-repellent roof.
