Anti-cracking construction method for residential external wall
The invention relates to the technical filed of external wall construction, and particularly discloses an anti-cracking construction method for a residential external wall. The anti-cracking construction method comprises the steps of painting an anti-cracking paint to a substrate, and painting the anti-cracking paint comprises the following specific steps that cement mortar is inlayed; a substratesurface is cleaned; putty is applied; sandpaper is grinded; planishing is conducted; an alkali-resisting glass fiber cloth is paced; the putty is conducted to secondary applying; an investment precoat is painted in a layered mode; and after painting, a constructor conducts a 24-hour continuous water spraying test on the surface of the external wall. According to the anti-cracking construction method for the residential external wall, the surface of an external wall substrate is fully pretreated on the basis of an existing external wall paint painting technology, the self inspection of the construction steps is added in the pre-treatment step, the leakage is timely checked, deficiency is timely supplied, the pretreated materials and construction method are improved, in addition, water-proof mortar is mixed with beneficial cement, a micro expansion agent, an anti-cracking fiber and an anti-cracking water retaining agent, the anti-cracking strength of the mortar surface is improved, andthe service life of the residential external wall is prolonged.
本发明涉及外墙施工技术领域，具体公开了一种住宅外墙防开裂施工方法，包括向基体粉刷防开裂涂料，防开裂涂料粉刷包括以下几个具体步骤：水泥砂浆补嵌、基体表面清理、批刮腻子、砂纸打磨、磨平、铺贴耐碱玻纤网格布、采二次批刮腻子、面层涂料的分层涂刷、涂刷完成后施工人员对外墙的表面进行24小时不间断的淋水试验。本发明提供的住宅外墙的防开裂施工方法在现有外墙涂料涂刷技术的基础上对外墙基体的表面进行了充分的预处理，且在预处理的步骤中增加对了施工步骤的自检，及时查漏补缺，对预处理的材料和施工方法进行改进，且在防水砂浆中掺有益胶泥、微膨胀剂、抗裂纤维和抗裂保水剂，提高了砂浆面的抗开裂强度，延长住宅外墙的使用寿命。
