Description
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 fitting-out work, the method is particularly suitable for the processing of inner wall of building corner coating.
Background technology
In building decoration engineering, to crack be the key factor that affects decoration quality to external and internal wall coating.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 bottom polishing is insufficient or do not have polishing, as bottom Polyester Paint, because its hardness is high, and good luster, good hand touch, polishes insufficient, as in japanning on glass, naturally causes interlayer poor adhesion, peels off; (3) priming paint do not match or matching poor, as use Polyester Paint bottoming, polish insufficient; With nitro bottoming, nitrate paint does not parch completely just using and contains the middle japanning that strong solvent is relatively many and cause the not obvious even finish paint cracking of the end of stinging; In the time changed by wooden tool effect or temperature, humidity, the inside and outside layer coefficient of expansion is different and cause cracking.(4) priming paint does not parch and is just coated with finish paint, or 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 fully dry, and pH value is (alkalescence is excessive) too.(6) construction environment is severe, and temperature is too low, the temperature difference is large, high humidity, and paint film is caught a cold heat effect and stretched, and causes be full of cracks.(7) be subject to externally temperature influence, timber and paint film convergent-divergent are inconsistent.If these crackles occur in the working face of body of wall spaciousness, for concrete reason, can take appropriate measures and overcome; But in the corner of indoor wall, because difficulty of construction is large, be difficult to control coating layer thickness, often cause crackle more concentrated, and be difficult to control.
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 providing, the method is conducive to simplify the construction of inner wall of building corner coating, cost is low.
The object of the invention is achieved through the following technical solutions:
A method of avoiding corner coating cracking in fitting-out work, comprises the steps:
(1) bracket at corner is fixing: the corner that bracket at corner is fixed on to interior wall, bracket at corner shape is identical with interior wall corner configurations, bracket at corner is 1-5cm at the width of corner body of wall, is highly corner body of wall spatial altitude, and the thickness of bracket at corner is 0.1-1cm;
(2) pretreatment of adhesive tape cloth and fixing: adhesive tape cloth is immersed in propyl benzene emulsion, Silicone acrylic emulsion or aqueous polyurethane after 1-10 hour to natural drying 10-24 hour in air, then paste or be fixed on bracket at corner and body of wall, exceeding bracket at corner width 1-5cm at the width of every face wall body adhesive tape cloth of corner;
(3) be coated with slurry: body of wall corner brushing paint together with metope.
For further realizing the object of the invention, described support is aluminum frame, aluminium alloy post, retort stand or galvanized iron support.
Described support is fixed on body of wall by steel nail or expansion bolt.
Described adhesive tape cloth is acetate fabric adhesive tape or gauze.
Natural drying 20-24 hour in described air.
Body of wall corner of the present invention coating in brushing paint together with metope is the conventional coating of house decoration.As the coating such as ippon, how happy scholar.
With respect to prior art, tool of the present invention has the following advantages and beneficial effect:
(1) the present invention fixes a support at the corner of interior wall, and on support fixation adhesive tape cloth then on adhesive tape cloth brushing paint be convenient to coating application, and be conducive to coating coating evenly.
(2) that adhesive tape cloth is immersed in propyl benzene emulsion, Silicone acrylic emulsion or aqueous polyurethane to 1-10 hour is again dry in the present invention, make adhesive tape cloth there is high resiliency, elongation rate increases 200-300%, and coating sizing-agent on the adhesive tape cloth after immersion is conducive to prevent coating cracking.
(3) the present invention is immersed in adhesive tape cloth in propyl benzene emulsion, Silicone acrylic emulsion or aqueous polyurethane, because performance and propyl benzene emulsion, Silicone acrylic emulsion or the aqueous polyurethane of coating approach, is conducive to the stable and bonding of coating.
(4) after tested, after 1 year, there is not any crack through corner coating in the fitting-out work of the inventive method processing.
