Problems solved by technology

[0003] At present, the traditional repair method is usually to use whitewashed gypsum leveling, internal pressure alkali-resistant glass fiber mesh cloth, and then scrape water-resistant putty for repair or use the original decoration process for repair, but the effect is often not good. Cracks began to appear again, especially for curved walls built with composite lightweight aggregate slats, the problem became more prominent

Embodiment 1

[0046] This embodiment provides a method for repairing cracks at the stubble joints of a composite lightweight aggregate slat wall, which includes the following steps:

[0047] S1. Base treatment: use a wide shovel to scrape off the decorative surface 3 on both sides of the crack with a distance of 80mm from the crack, expose part of the first composite light aggregate strip 1 and part of the second composite light aggregate strip 4, and expose The residual substances on part of the first composite light aggregate slat 1 and part of the second composite light aggregate slat 4 are cleaned up to obtain the first bare panel and the second bare panel.

[0048] S2, brushing interface agent: take interface agent, evenly brush on the surface of the first exposed panel and the second exposed panel in step S1, to obtain an interface agent layer with a thickness of 1.5mm, the interface agent has very strong permeability, can The surfaces of the first exposed panel and the second exposed...

Embodiment 2

[0057] This embodiment provides a method for repairing cracks at the stubble joints of a composite lightweight aggregate slat wall, which includes the following steps:

[0058] S1. Base treatment: use a wide shovel to scrape off the decorative surface 3 on both sides of the crack with a distance of 50mm from the crack, expose part of the first composite light aggregate strip 1 and part of the second composite light aggregate strip 4, and expose The residual substances on part of the first composite light aggregate slat 1 and part of the second composite light aggregate slat 4 are cleaned up to obtain the first bare panel and the second bare panel.

[0059] S2, brushing interface agent: take interface agent, evenly brush on the surface of the first exposed panel and the second exposed panel in step S1, to obtain an interface agent layer with a thickness of 1.8mm, the interface agent has very strong permeability, can The surfaces of the first exposed panel and the second exposed...

Abstract

The invention relates to a method for repairing a crack at a jointing part of a composite lightweight aggregate batten wall and belongs to the technical field of building decoration. The method comprises the following steps: treating a base course; brushing an interface agent; brushing a first layer of gypsum; paving an anti-cracking paper tape; brushing a second layer of gypsum; brushing a firstlayer of putty; paving alkali-resisting glass fiber gridding cloth; and brushing a second layer of putty to finish repairing the crack. With adoption of the method, the anti-cracking capacity at the jointing part between the composite lightweight aggregate battens is greatly enhanced, and the appearance quality of the composite lightweight aggregate batten wall is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of architectural decoration, and in particular relates to a method for repairing cracks at stubble joints of a composite light aggregate slat wall and a repair layer thereof. Background technique [0002] In the construction of concrete engineering or building decoration, etc., composite light aggregate slats are often used as partition walls, and then a decorative surface layer is laid on the surface of the composite light aggregate slats for decoration, which is very convenient to use. When the composite lightweight aggregate slats are spliced, gaps will be formed at the stubble joints. After filling the gaps with mortar, the decorative surface layer will be laid for decoration, and the laid decorative surface will have cracks on the surface due to the gaps, which will affect the appearance. . The cracks on the decorative surface at the indirect stubble of composite lightweight aggregate slabs, especially...
