Note: the next layer is generally applied at an interval of 24, and a rough surface must be left between layers.
(3) The insulation layer must be firmly bonded with the base and each structural layer without delamination, hollowing and cracks.

Precautions for crack resistant mortar construction? 1.
Lay alkali resistant glass fiber mesh (1) when the surface of thermal insulation mortar is polished, press the alkali resistant glass fiber mesh directly on the material surface with a trowel and polish it at the same time.
Cleaning (1) after the wall coating is completed, the construction site shall be cleaned in time, and the fallen thermal insulation mortar shall be recycled in time, and those that can be reused shall be reused.
(4) During layered coating, it shall be pressed moderately to ensure effective bonding between layers, but it is not allowed to wipe and press back and forth at the same part.
At the same time, the floor of the construction part shall be cleaned to facilitate the cleaning of the floor insulation mortar generated during plastering after plastering.
The workability can be controlled according to the climate and temperature, and it can be used as soon as it is mixed.
3.
It can be widely used in interior and exterior walls of various buildings.
In case of bulge during application, it shall be removed and repaired in time.
(3) After the initial setting of the second layer is formed (add steel wire mesh), the third layer shall be applied with a thickness of no more than 2cm.
For reinforced concrete, the protrusions on the concrete shall be removed, and the residual sponge strip or adhesive tape at the formwork joint shall be cleaned.
For the base course with strong water absorption or excessively dry surface, the base course shall be painted with bottom sealing agent or sprayed with a small amount of clean water before construction.
7.
Inspection and finishing (1) the surface of the base course shall be clean, the joints shall be flat, there shall be no plastering lines, and the lines and corners shall be straight and clear.
8.
Then apply the boundary agent or roughen it with.
How to use anti crack mortar? 1.
6.
After drying, it forms a rough surface.
The subsequent process construction can be carried out after the insulation layer is cured for 7 days.
It is strictly prohibited to omit laying.
Xiaoencyclopedia anti cracking mortar is a new type of anti cracking material with certain toughness.
3.
It is not necessary to add any admixture for the on-site construction of anti crack mortar, and the water-solid ratio and plastering time shall be strictly controlled.
Thermal insulation mortar shall be applied layer by layer (1) mixing: manually mix the thermal insulation mortar according to the thermal insulation mortar: water = 1:1 (weight) to form a paste.
6.
The required thickness shall not exceed 1.5cm and must be compacted with rough surface left on the surface.
(2) Alkali resistant glass fiber mesh shall be laid flat and without wrinkles, and shall be overlapped in sequence, with the overlapping width of 30-50mm; When laying the outer eaves, the overlapping width is 80-100mm; Press and paste 100mm wide alkali resistant glass fiber mesh at the joint of external corner and thermal insulation.
5.
It has the effects of no cracking, yellow and falling off, so that the putty has better adhesion, simple operation, non-toxic and environmental protection.
7.
The control point of cake thickness shall be set with thermal insulation mortar, the size is 20 * 20, the thickness is the required thickness of thermal insulation layer, and the spacing of thermal insulation layer thickness control points should be within 1.5m.
4.
In fact, anti crack mortar is a kind of anti crack construction material, which solves a major problem that has been perplexing the construction industry – the fracture of light body insulation layer.
Pay attention to moisture, rain and sun protection during transportation.
During storage, the anti crack mortar shall be stored in a dry and ventilated place to avoid moisture.
(2) The thickness of insulation layer must meet the design requirements, and negative deviation is not allowed in single point thickness detection.
(2) After the construction of the insulation layer is completed, a good ventilation and dry environment shall be maintained without watering.
It is directly applied to plywood, calcium silicate board and mortar wall.
Apply the banner interface agent or roughen the cleaned base course, fully apply the special interface agent or roughen it, apply 3-4mm thick anti crack mortar along the joint between reinforced concrete and aerated concrete, then press in 400 wide alkali resistant mesh cloth, 200 wide on each side, and the surface is troweled with anti crack mortar.
Remove the floating dust on the base and spray with water in advance to wet it.
Hotline: 13207528807 many people may not know what anti crack mortar is and how to use it.
2.
The construction and storage temperature shall be above 5 ℃.
5.
If it is caked before use, it cannot be used any more.
For base course treatment, the sundries on the slab bottom or plastered surfaces such as concrete and blocks shall be cleaned.
The anti crack mortar shall not be mixed too much at one time, depending on the construction amount.
(2) Apply a layer of insulation mortar.
Statement: issued by putty mortar branch.
After each construction, the construction tools and mixing equipment shall be cleaned in time to avoid affecting the next use.
Apply anti crack mortar according to the construction requirements of anti crack mortar.
