A kind of method of avoiding corner coating cracking in the fitting-out work
Technical field
The present invention relates to a kind of building finishing coating for wall surface coating, particularly relate to a kind of method of avoiding corner coating cracking in the fitting-out work, this method is particularly suitable for inner wall of building corner coating and handles.
Background technology
To crack be the key factor that influences decoration quality to the external and internal wall coating in the building decoration engineering.Its main cause relates to: (1) surface of wall is unclean, speckles with greasy dirt, moisture or dirt.(2) bottom surface is too smooth, and the bottom polishing is insufficient or do not have polishing, coat with lacquer with polyester like bottom, because its hardness is high, and good luster, good hand touch, it is insufficient to polish, and as in japanning on glass, causes the interlayer poor adhesion naturally, peels off; (3) priming paint do not match or matching poor, as with polyester lacquer bottoming, it is insufficient to polish; With nitro bottoming and nitrate paint does not parch fully just using and contains the more relatively middle japanning of strong solvent and cause the not obvious end even the finish paint cracking stung; The about layer coefficient of expansion is different and cause cracking when changed by wooden tool effect or temperature, humidity.(4) priming paint does not parch and just is coated with finish paint, or the first floor finish paint is blocked up, without parching and overcoating second layer finish paint, makes two coatings flexible inconsistent.(5) cement bottom layer is without abundant drying, and pH value is (alkalescence is excessive) too.(6) construction environment is abominable, and temperature is low excessively, the temperature difference big, high humidity, and paint film is caught a cold heat effect and stretched, and causes be full of cracks.(7) receive externally temperature influence, timber and paint film convergent-divergent are inconsistent.If these crackles occur on the spacious working face of body of wall, to concrete reason, can take appropriate measures overcomes; But in the corner of indoor wall,, be difficult to the control coating layer thickness, often cause crackle more concentrated, and be difficult to control because difficulty of construction is big.
Summary of the invention
The present invention is in order to solve above technical problem, and a kind of method of effectively avoiding inner wall of building corner coating to crack that provides, this method helps simplifying the construction of inner wall of building corner coating, cost is low.
The object of the invention realizes through following technical scheme:
A kind of method of avoiding corner coating cracking in the fitting-out work comprises the steps:
(1) the corner support is fixing: the corner that the corner support is fixed on interior wall; Corner support shape is identical with the interior wall corner configurations; The corner support is 1-5cm at the width of corner body of wall, highly is corner body of wall spatial altitude, and the thickness of corner support is 0.1-1cm;
(2) preliminary treatment of adhesive tape cloth is with fixing: adhesive tape cloth is immersed in propyl benzene emulsion, Silicone acrylic emulsion or the aqueous polyurethane after 1-10 hour in the air air dry 10-24 hour; Paste then or be fixed on corner support and the body of wall, the width of adhesive tape cloth exceeds corner support width 1-5cm on every face wall body of corner;
(3) be coated with slurry: the body of wall corner is with the metope brushing paint.
For further realizing the object of the invention, said support is aluminum frame, aluminium alloy post, retort stand or galvanized iron support.
Said support is fixed on the body of wall through steel nail or expansion bolt.
Said adhesive tape cloth is acetic acid cloth rubber belt or gauze.
In the said air air dry 20-24 hour.
The coating of body of wall corner of the present invention in the metope brushing paint is house decoration coating commonly used.Like coating such as ippon, how happy scholars.
With respect to prior art, the present invention has following advantage and beneficial effect:
(1) the present invention is at the fixing support of the corner of interior wall, and fixation adhesive tape cloth on the support then on adhesive tape cloth brushing paint be convenient to coating application, and help the coating coating evenly.
(2) that adhesive tape cloth is immersed in propyl benzene emulsion, Silicone acrylic emulsion or the aqueous polyurethane 1-10 hour again is dry in the present invention; Make adhesive tape cloth have high resiliency; Elongation rate increases 200-300%, and coating sizing-agent on the adhesive tape cloth after the immersion helps preventing the coating cracking.
(3) the present invention is immersed in adhesive tape cloth in propyl benzene emulsion, Silicone acrylic emulsion or the aqueous polyurethane, because performance and propyl benzene emulsion, Silicone acrylic emulsion or the aqueous polyurethane of coating are approaching, helps the stable and bonding of coating.
(4) through test, through corner coating in the fitting-out work of the inventive method processing any crack did not appear after 1 year.
The specific embodiment
In order further to understand the present invention, below in conjunction with embodiment the preferred embodiment of the invention is described, describe just to further specifying feature and advantage of the present invention but should be appreciated that these, rather than to the restriction of claim of the present invention.
Embodiment 1
A kind of method of avoiding corner coating cracking in the fitting-out work comprises the steps:
(1) the corner support is fixing: the corner support is fixed on the corner of interior wall, and corner support shape is identical with the interior wall corner configurations, and the corner support is 3cm at the width of corner body of wall, highly is corner body of wall spatial altitude, and the thickness of corner support is 0.5cm; Support is an aluminum frame, and support is fixed on the body of wall through steel nail.
(2) preliminary treatment of adhesive tape cloth is with fixing: adhesive tape cloth was soaked after 5 hours in the air air dry 20 hours in aqueous polyurethane; Paste then or be fixed on corner support and the body of wall, the width of adhesive tape cloth exceeds corner support width 3cm on every face wall body of corner; Adhesive tape cloth is the acetic acid cloth rubber belt.
(3) be coated with slurry: the body of wall corner is with the metope brushing paint.The coating of body of wall corner of the present invention in the metope brushing paint is house decoration how happy scholar's coating commonly used.
Through observation, through corner coating in the fitting-out work of present embodiment method processing any crack did not appear after 1 year.
