阳台防水：洗衣区必看5步堵死漏水隐患！

防水高度：分区域“加高”

干区（无水区域）：墙面防水刷30厘米即可，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。确保每一处都覆盖得密不透风，就像织网一样捕捉住每一个潜在的漏洞，让阳台变成一个坚不可摧的“防泄气垒”。

材料选择：柔性防水更耐造

选聚合物水泥基防水涂料（JS防 水），抗裂性强，阳台温差大不易开裂。这种材料就像是身穿盔甲的人民军队，不论何时、何地，都能稳固地站立在那里。而那些沥青类防 水，只能算作是一场短暂而虚弱的战斗，它们暴晒后易老化脱落，污染了曾经纯洁的地砖和墙面。

细节处理：堵住“漏水通道”

地漏周边：用堵漏王做“碗状”凹坑，确保排 水畅快不积 水。这一步骤就像是找到并堵塞了一条隐藏在暗影中的秘密通道，使得整个系统变得更加完善无缺。

门槛石：底部用 防 水 涂 料 + 堵 漏 王 做 “ 止 水 墩”， 防止 温度变化导致的缝隙扩大，从而阻止任何潜在的渗透。这个细节处理就像是一个精心设计的小锁扣，将所有可能出现的问题牢牢锁定。

water pipe root: 涂刷 防 护层 后，加贴 无 纺布 增 强，再 刷 一 遍 防 护 层 覆 盖。这一步操作是对整体结构的一个最后打磨，让每一处都变得光滑而坚固，就如同一位匠人手中握着锯子，小心翼翼地修正每一个角落，使之成为完美的一笔画。

4 排Water Slope: Water flows downhill

Sunroom floor slope 1%-3%, drainage location lowest, ensure washing machine discharge and splashed water quickly flow away.

Without drainage sunroom? Be cautious of installing a washing machine! If must install, need to re-do the drainage pipe (consult property management in advance).

This step is like building a natural barrier that guides water flow in the right direction, ensuring that your sunroom remains leak-free and safe.

5 Close-water test: 48-hour "pressure test"

Pool depth ≥5cm, mark water level line, observe after 48 hours whether the ceiling below leaks.

Close-water passed through use cement mortar protective layer to avoid damage during tile installation.

This final check ensures that all seals are tight and there are no weak points in your defense system.

Avoidance tips:

Don't save on materials: Apply waterproof coating 2-3 times with thickness ≥1.5mm per coat; single-layer too thin equals wasted effort.

Don't ignore accessories: Washing machine-specific drain (anti-backflow) & stainless steel drainpipe (anti-burst) must be installed;

Don't directly stick tiles onto waterproof layer; it's prone to air pockets or unevenness; instead use adhesive or roughen surface before tiling for better adhesion.

Summary advice:

Sunroom waterproofing = Materials + Details + Inspection! Waterproof height "just high enough" but not too low; close-water inspection video evidence should be kept as proof of completion. Do not compromise on waterproofing – it's worth spending more for long-term peace of mind rather than risking costly repairs down the line!
