因為要講地話較多,我用回文的方式說明,以供參考
一般在頂樓的泥做設施,日曬時間較長,很容易因為熱漲冷縮,造成牆壁產生裂痕
所以此處施工,水泥的養生很重要,但很難啦...沒幾個人會這麼做
如果這沒有危險性,僅是暇疪,我會建議等個一年,待泥做完整反應全部的物理現象
再一次性使用"彈性補土"做填縫,而後再使用一般補土來批,砂磨,上漆
您所PO的相片裡,有張窗廉的"應力裂痕"(即在窗戶四角處,產生45度角的裂痕)
那必須在窗牆開口四周結構體上,釘上15公分以上寬度的不銹鋼網,再敷上水泥才能強化
否則一經地震,或大車的經過,窗沿就會出現這種角度的裂痕,久之滲水也就難以避免
而磁磚的繃裂,我的看法如同第二行所述
在工序上,最有可能的是磁磚未給予足夠時間的浸泡,或壁體沒經過潤濕
使得水泥硬化過快,收縮率超過了壁磚的承受力了...
如果有扣款,趁剛完工,可要求磁磚復原
不然時間一久,同花色的磁磚就難尋了
