阳台防水：洗衣区必看5步堵死漏水隐患！太阳能热水器安装时不容忽视。

防水高度：分区域“加高”

干区（无水区域）：墙面防水刷30cm即可，防止溅水渗透。

湿区（洗衣区）：墙面防水刷到1.2米高，地面全刷，尤其洗衣机背后、水管周围。

材料选择：柔性防水更耐造

选聚合物水泥基防水涂料（JS防water），抗裂性强，阳台温差大不易开裂。

避免用沥青类防water，暴晒后易老化脱落，污染墙面。

细节处理：堵住“漏water通道”

地漏周边：用堵漏王做“碗状”凹坑，确保排water畅快不积water。

门槛石：底部用防water涂料+堵漏王做“止water墩”，防止Water汽渗入客厅。

水管根部：涂刷 defends, 后，加贴无纺布增强，再刷一遍 defend Covers.

排water坡度：Water往低处流

阳台地面做1%-3%坡度，地漏处最低，确保洗衣机排wate和溅wate快速流走。

无地漏阳台？慎放洗衣机！若必须装需重新做排wate管(提前咨询物业).

闭Waters试验:48小时"压力测试"

蓄Waters深度≥5cm标记Water位线48小时后观察楼下天花板是否渗Waters.

闭Waters通过后，用cement sand浆做defends保护层避免贴砖时划伤defends层.

避坑指南：

不省材料: defends涂刷2-3遍, 厚度≥1.5mm, 单遍太薄等于白do.

不忽视配件: 洗衣机专用geleak (prevents return of Water), nix stainless steel drain pipe (prevents burst) must install.

不贴wall brick: defends layer on top directly stick to brick easy air pocket; need first do rough treatment or use ceramic tile adhesive.

总结建议:

阳台defends = materials + details + verification!

Defends height in washing area "high but not too high", close water test after and take video as evidence for proof of defense against leaks! Defending against leaks is crucial; otherwise, water damage may cost a fortune!
