Abstract
The invention discloses an anti-cracking real stone paint spraying method, which comprises the following steps: s1, processing a base layer to be smooth and rough; s2, coating and scraping a leveling layer by adopting exterior wall putty powder, and polishing and leveling the exterior wall putty leveling layer after drying; s3, removing floating ash on the leveling surface of the outer wall putty after polishing and leveling, reserving a first expansion joint, spraying a primer for the first time, reserving a second expansion joint after the primer for the first time is dried, and spraying a primer for the second time; s4, after hardening the primer, polishing the outer surface to be rough by using sand paper, removing floating ash, reserving a third expansion joint, and then spraying real stone paint; and S5, spraying finish paint after the stone paint is dried. The method has the advantages of convenient operation, simple steps, easy construction and good anti-cracking effect.
Description
Technical Field
The invention relates to the technical field of building coatings, in particular to a method for spraying anti-cracking real stone paint.
Background
The stone-like paint is a building material prepared by mixing a plurality of natural stone powders and a plurality of bonding materials according to a certain proportion, and is usually applied to building external walls and internal walls because the appearance and the feeling effect are similar to natural stone, and the cost is far lower than that of the natural stone. The stone-like paint has the advantages of low cost, good safety, short construction period, beautiful effect and the like, and is widely popularized in recent years.
Because the stone-like paint is directly attached to the outer surface of the building, the outer surface of most buildings is a cement mortar layer, the stone-like paint is generally not easy to fall off when being attached to the surface of the cement mortar layer, but the stone-like paint also can fall off due to the problems of construction process and product quality. And the quality problems of cracking, falling and the like of the stone-like paint caused by the temperature difference are more common.
Disclosure of Invention
The invention provides a cracking-proof real stone paint spraying method for solving the problem that the real stone paint is easy to crack and fall off in the background technology.
The invention adopts the following technical scheme:
the anti-cracking real stone paint spraying method is characterized by comprising the following steps:
s1, base layer treatment: the outer surface of the building base layer is flat and rough, and has no floating ash, no stain, no iron nails and other materials;
s2, leveling putty: coating and scraping a leveling layer by adopting exterior wall putty powder, and polishing and leveling the exterior wall putty leveling layer after drying;
s3, primer spraying: removing floating ash on the outer surface of the polished and leveled outer wall putty, reserving a first expansion joint, spraying the primer for the first time, reserving a second expansion joint after the primer for the first time is dried, and spraying the primer for the second time;
s4, spraying of real stone paint: after the primer is hardened, the outer surface is polished to be rough by using sand paper, floating ash is removed, a third expansion joint is reserved, and then stone paint spraying is carried out;
s5, spraying finish paint: and spraying finish paint after the real stone paint is dried.
Specifically, in the step S2, the thickness of the putty leveling layer is 5mm to 12mm, and the external wall putty powder used by the putty leveling layer is 300 to 350 meshes.
Specifically, in the step S3, the first expansion joint and the second expansion joint are arranged at staggered positions.
Specifically, the third expansion joint in the step S4 is disposed at a position offset from the second expansion joint in the step S3.
Specifically, the widths of the first expansion joint, the second expansion joint and the third expansion joint are between 4mm and 8 mm.
Compared with the prior art, the invention has the beneficial effects that: the invention combines the conventional real stone paint method, the expansion joints are arranged before the priming paint spraying and the real stone paint spraying, and each expansion joint is arranged in a staggered way, so that the priming paint and the real stone paint coating are alternately arranged, under the condition of temperature influence, the displacement between the coatings is restricted by the expansion joints, and the cracking caused by the deformation between the coatings is avoided. The construction method is simple, convenient to operate, good in crack resistance, suitable for various environments and suitable for being popularized vigorously.
Detailed Description
The present invention is further illustrated by the following examples, which should not be construed as limiting the scope of the invention.
Example 1: a cracking-resistant real stone paint spraying method comprises the following steps:
s1, base layer treatment: the outer surface of the building base layer is flat and rough, and has no floating ash, no stain, no iron nails and other materials;
s2, leveling putty: coating and scraping a leveling layer by adopting exterior wall putty powder, and polishing and leveling the exterior wall putty leveling layer after drying;
s3, primer spraying: removing floating ash on the outer surface of the polished and leveled outer wall putty, reserving a first expansion joint, spraying the primer for the first time, reserving a second expansion joint after the primer for the first time is dried, and spraying the primer for the second time;
s4, spraying of real stone paint: after the primer is hardened, the outer surface is polished to be rough by using sand paper, floating ash is removed, a third expansion joint is reserved, and then stone paint spraying is carried out;
s5, spraying finish paint: and spraying finish paint after the real stone paint is dried.
Specifically, in the step S2, the thickness of the putty leveling layer is 5mm to 12mm, and the external wall putty powder used by the putty leveling layer is 300 to 350 meshes.
Specifically, in the step S3, the first expansion joint and the second expansion joint are arranged at staggered positions.
Specifically, the third expansion joint in the step S4 is disposed at a position offset from the second expansion joint in the step S3.
Specifically, the widths of the first expansion joint, the second expansion joint and the third expansion joint are between 4mm and 8 mm.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
