Abstract

The invention discloses modified direct-scraping thin-layer plastering mortar and a construction method. The plastering mortar is prepared from the following components in parts by weight: 150-200 parts of cement, 700-820 parts of sand, 60-90 parts of mineral micro powder, 0.5-1.2 parts of dispersible latex powder, 0.5-1 part of a thickening agent, 0.2-0.6 part of alkaliproof fibers, 0.1-0.5 part of thixotropic lubricant powder, 0.5-2 parts of multifunctional powder and 150-170 parts of water. The mortar materials disclosed by the invention are small in construction dosage, simple in technology, excellent in bonding force, excellent in crack resistance, and not liable to hollow and crack, the efficiency is greatly improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a building material, in particular to a modified direct-scraping thin-layer plastering mortar and a construction method. Background technique [0002] Plastering mortar is a decorative project that is applied on the walls, roofs, floors, columns and other surfaces of buildings and directly made into a finishing layer. It can not only protect the base layer, increase the appearance, but also provide special functions for the building. The construction process of ordinary ready-mixed plastering mortar includes base treatment, net hanging, leveling, plastering and maintenance. Due to the low adhesion of traditional mortar, the interface is directly hanged without treatment, the mortar layer is thin, and the mortar is easy to fall off and crack. Therefore, in order to have better bonding performance of the mortar layer, the surface of the wall needs to be moistened during the base treatment process. Wet and brush polymer cement mo...
