Abstract
The invention discloses a novel construction process capable of preventing the coats of an inner wall and an outer wall from cracking and discoloring. The construction process comprises the steps of paving a layer of fiberglass meshes or iron wire nets on a cement mortar rendering layer of each of the inner wall surface and the outer wall surface of a building; then paving a putty layer; coating acrylic waterproof primer at one to two times; then coating acrylic elastic coating at one to two times. The wall surfaces constructed by the process are avoided cracking of the coats on the wall surfaces, and the color can be maintained for more than ten years.
Description
Technical field
The invention belongs to building coating for internal and external wall construction technology technical field, what relate to is a kind of coating application technique preventing inner-outer wall coating cracking and decolouring.
Background technology
What current building coating for internal and external wall construction adopted is traditional coating application technique: first do putty layer on building inner-outer wall cement mortar floated coat surface, then brush 1-2 all over alkali resistant sealing bottom coating material, alkali resistant sealing bottom coating material is 1-2 all over topcoat paint.Although this traditional coating application technique is fairly simple, because building inner-outer wall wash cement mortar plastering layer is different from building inner-outer wall body of wall material, in dry run, cement mortar floated coat surface can produce the strain crack differed in size.These strain cracks differed in size can make building inner-outer wall surface coating ftracture, and the alkali part in cement mortar floated coat makes the color of coating that transfer decolouring occur by the paint cracks on building inner-outer wall surface.Particularly southern china rainy humid region building has just been handed over soon, and building surface coating just there will be cracking and decolouring phenomenon, and very ugly, rainwater enters in building the safety endangering resident family and building masonry wall by building surface coating crack.
Summary of the invention
The present invention is to provide a kind of coating application technique preventing building inner-outer wall coating cracking and decolouring.
In order to overcome existing building inner-outer wall coating cracking and decolouring phenomenon, the present invention proposes one and spreading one deck grid cloth between original cement mortar floated coat and putty layer, increasing the effect of prestressed of putty layer and dope layer.
In order to realize foregoing invention object, present invention employs following technical scheme: first the cement mortar floated coat surface of outside spreads one deck grid cloth in building wall, do putty layer again, then 1-2 is brushed all over brushing 1-2 after sealing acrylic primer again all over acrylic acid painting coating, to reach the effect of prestressed increasing putty layer and dope layer, prevent the decolouring of coating.
Owing to have employed technical scheme described above, the present invention has following good effect:
First the cement mortar floated coat surface of the present invention outside in building wall spreads one deck grid cloth, then does putty layer, then brushes 1-2 all over brushing 1-2 after sealing acrylic primer again all over acrylic acid painting coating.Because in building wall, first the cement mortar floated coat surface of outside spreads one deck grid cloth, this layer of grid cloth adds the pulling force of putty layer, the crackle that cement mortar floated coat is less than 1-2 millimeter for putty layer, dope layer without any impact.Dope layer does not ftracture, and rainwater can not enter in the crack of cement mortar floated coat, and the alkali part in cement mortar floated coat can not ooze out dope layer surface, maintains color and the quality of dope layer, ensures that the wall surface coating of building does not ftracture and decolours for 10 years.
Detailed description of the invention
The surperficial grid cloth first spreading layer of glass or polyethylene or iron wire and make of the cement mortar floated coat of the present invention outside in building wall, do putty layer again, then 1-2 is brushed all over brushing 1-2 after sealing acrylic primer again all over acrylic acid painting coating, to reach the effect of prestressed increasing putty layer and dope layer, prevent the decolouring of coating.
Below in conjunction with embodiment, set forth the present invention further:
Embodiment 1
In building wall, first the cement mortar floated coat surface of outside spreads layer of glass grid cloth, do putty layer again, then 1-2 is brushed all over brushing 1-2 after acrylic acid anticracking waterproof coating again all over acrylic acid elasticity painting coating, to reach the effect of prestressed increasing putty layer and dope layer, prevent the decolouring of coating.
Embodiment 2
In building wall, first the cement mortar floated coat surface of outside spreads layer of polyethylene fibrous mesh cloth, do putty layer again, then 1-2 is brushed all over brushing 1-2 after sealing acrylic primer again all over acrylic acid painting coating, to reach the effect of prestressed increasing putty layer and dope layer, prevent the decolouring of coating.
Claims (5)
1. one kind prevents the coating application technique of inner-outer wall coating cracking and decolouring, it is characterized in that first the cement mortar floated coat surface of this construction technology outside in building wall spreads one deck grid cloth, do putty layer again, then brush 1-2 and brush 1-2 acrylic acid painting coating again all over after sealing acrylic primer.
2. a kind of coating application technique preventing inner-outer wall coating cracking and decolouring according to claim 1, is characterized in that: first the cement mortar floated coat surface of this construction technology outside in building wall spreads one deck grid cloth, then does putty layer.
