Posting mesh is better, it can also level up by burnt gypsum and then plaster putty.
Mesh is used in external wall thermal insulation building, it will not have a "thermal bridges" or "cold bridges" phenomenon, which has a good effect on building energy efficiency. It is toasted by the construction! In winter, when indoor heat through the mesh wall insulation materials will be isolated and preserved, and when the room temperature drops down, the heat of wall will be released, so as to adjust the indoor temperature; in summer, exterior mesh insulation will also prevent the sun's heat radiation and external incoming interior, so as to keep warm in winter and cool in summer of the building indoor environment, residential indoor environment and physical performance have been significantly improved.
Of course, pasting the whole wall is the best, but the mesh is usually used for cracking at the joint, the whole crack?resistance of dacron cloth is better, but it will increase the budget of $ 5-8. If it is a new house, decoration has better to do patch treatment; if it is second?decoration, the walls are relatively intact, it is not necessary to paste.
So we must follow the specific steps
The mesh can be used for moisturizing or thermal insulation on the wall, mesh is also an important advertisement material, which can effectively avoid the tension contraction and cracking caused by external forces of whole surface in the plastering layer, and thin mesh is often used in refurbishment of wall and interior wall insulation.
