磁磚外牆防水工程






磁磚外牆透天屋.外觀看起來沒啥異樣!

當進入屋內才知道壁癌如此嚴重

搭架後隔天進場施工.遊走鷹架間.看到了磁磚縫不只是嚴重龜裂.還堆積泥砂(圖左上).並且泥砂堅硬還長了青苔(圖右上).再看抿石牆與窗框銜接處(圖左下)..抿石居然彭龜成薄膜狀.而屋簷角邊居然有個大洞(圖右下).因為水泥長年粉化掉落形成這般天然奇景!
 經過2天大力刷洗.配合砂輪機與高壓清洗機作業.終於牆體洗淨.
牆體洗淨後.清楚看見磁磚縫龜裂情形

磁磚縫重新填縫

窗框外側應加強防水補強


基礎修補工作完成後.開始進行底塗與上塗


底塗時.磁磚縫內施作2道矽酸質滲透結晶材.會再次激起水泥活性提升防水戰力.待養護完乾燥後.再施作2道無膜透氣型油性撥水劑.乾燥後形成長效抗污.耐候.防水並透氣的呼吸塗層.

牆壁透氣的功能:
外牆塗層透氣.塗層不龜裂不突起.牆體常保乾燥.壁癌不生.是現代塗裝的首選工法!
