为什么很多家庭的美缝剂都凹陷在瓷砖里？
为什么很多家庭的美缝剂都凹陷在瓷砖里，看上去黑黑的？哪种美缝剂干了会比较饱满？我们装修过程的收尾工序，非瓷砖美缝莫属，因为大面积美缝提前做好；
有被别的装修工具弄坏隐患，所以等到主要装修工序完毕之后，才是大面积美缝的施工表演。为什么会出现美缝都凹陷在瓷砖里还是黑黑的状况？不饱满又是怎么回事？下面让“花哥”为大家来解开这个疑惑。
美缝凹陷在瓷砖里面是怎么回事？美缝凹陷如果是非常一致的凹陷是正常现象，因为瓷砖缝隙里面注入美缝胶之后，会用压缝钢球或者钨钢压缝板对其做一个收匀压严实的动作。
瓷砖缝隙里面多余的美缝胶会溢出，呈现一个八字形态粘接在缝隙两边的瓷砖上面，美缝胶干燥之后用铲刀平行与瓷砖铲掉多余的，缝隙里面的美缝胶铲刀接触不到，所以随便怎么铲都没事。
由于压缝隙的钢球是圆弧形状，钨钢压缝板前端也是圆弧状，所以最后瓷砖缝隙呈现在我们面前的也是均匀的半圆弧度效果。
只有凹陷不均匀才会不好看，当瓷砖的某处缝隙美缝胶弧度突然就深凹下去，或者会比较平，这就不太正常了。
美缝凹陷不均匀通常有三个原因情况1）瓷砖几何尺寸不好，当瓷砖的几何尺寸非常的不好的话，泥瓦工铺贴就不能够保证缝隙的大小一致。尤其在四块瓷砖的九十度角交汇位置，会出现有瓷砖一角突然高低不等的现象。①、缝隙大小不一致，不论压缝钢球或者钢板就无法保证其缝隙饱满程度，缝隙尺寸都不同，压缝工具与其接触的面积肯定就有偏差，缝隙宽的和缝隙窄的地方自然就有区别。②、两块瓷砖有高矮，压缝工具就向矮的一侧倾斜，那么压出来的缝隙弧度就会特别不自然（不会特别凹陷）。情况2）泥瓦工铺贴时缝隙里面的杂质较多，或者瓷砖在切割时候有破损，也会导致美缝胶干燥铲掉时候出现不均匀现象。所谓的杂质也就是残留的水泥没有及时进行处理，正常现象不会有太多，稍微的一点是在所难免，如果美缝商家也懒得处理或者处理不到位，那肯定就会呈现美缝胶缝隙不均匀。情况3）当美缝商家进行美缝施工时，会对缝隙做一个清理，接着用气泵吹干净灰尘才会对缝隙进行打胶。如果遇到做事不负责的工人对缝隙处理不认真，缝隙内存在杂质那美缝剂最后的展示效果肯定会特别差，特别是缝隙存在水泥，美缝剂凹陷状态肯定就会特别不均匀。美缝发黑或者发白怎么回事？1）美缝发黑通常与美缝胶的质量以及施工分不开，由于材质为环氧树脂+颜料与固化剂混合在一起产生的。美缝剂发黑主要是灰尘以及涂打美缝胶时打得不多，有灰尘的话，灰尘混合在美缝剂里面肯定会发黑。同时美缝剂涂打过程不饱满，用不规则的工具收缝隙，瓷砖底层边缘的水泥就会显露。{!-- PGC_COMMODITY:{"charge_url":"https://uland.taobao.com/ccoupon/edetail?e=tOK%2FMpVVO50GQASttHIRqQCgbw9kNBb7RaUIgNtZiaqqxhdm6Navecd37g%2Fm0Cpp9xLnAcTPV6oT5awPToJieVAZaFjg0QxJ9FCHTCQmH28nZ16HabWLU2es8km6%2FnRxcYGT8tarCqma0zrDB%2FfQYP%2BwjH3DCmJrlDnB8bP%2B7409oeDbO1ayY9O6UBgFVvsmJnpj%2BmQe1PlBLQWW799tKi%2BQFCU%2FXXZwAJtV5SE2TVpPJKPpqS6DUj9lK3DYkB14JumwG8FPJqRE%2FvnAbNRDeQ%3D%3D&traceId=0bb623ec16173541057562147e60b4&union_lens=lensId:TAPI@1617354105@0b8476a9_f448_17891d123eb_9523@01","client_goods_data":"{\"promotion_id\":\"3315726366465498216\",\"product_id\":\"545946056107\",\"title\":\"德高美缝剂十大品牌美缝胶瓷砖地砖专用填缝剂勾缝瓷缝剂施工工具\",\"cover\":\"https:\\/\\/p1.toutiaoimg.com\\/img\\/cmp-ecom-alliance\\/FkIf0HgWAfdVmcwh7fmFFVPA9PQc.jpg~400x0.webp\",\"price\":15900,\"market_price\":39800,\"cos_fee\":239,\"detail_url\":\"sslocal:\\/\\/webview?swipe_mode=1&url=https%3A%2F%2Fs.click.taobao.com%2Ft%3Fe%3Dm%253D2%2526s%253DrRcl6iIfzhVw4vFB6t2Z2ueEDrYVVa64yK8Cckff7TVRAdhuF14FMRRBA%252B6kq7Lr1aH1Hk3GeOif5nGvxlR28b8iqH%252F5lqnzPbQarJ22nn%252Bks8Xx9ge2LJ8yQnCH6WE9i63DAi4kPA%252BXlhgVgeBFgQtkyqhBb5%252B4x8PUddoNe3Agw3DTlIZsxpz4CsMBmzq44JOed0Rxa6M5b1wVol%252FpsGkunOkzL8PQmVrGphhu%252FZEahBoPvMeUI8ybej9eVyNc%252FIjZefNyPKOTCpmaT0DBiq%252FY1S%252FD%252B%252BGaYv8Ah3oUTSU%253D%26union_lens%3DlensId%3ATAPI%401617354106%402108104c_0890_17891d126de_a119%4001\",\"sales\":6664,\"item_type\":7,\"cos_ratio\":1.5,\"favor\":false,\"in_shop\":false,\"platform_label\":\"淘宝\",\"h5_url\":\"https:\\/\\/s.click.taobao.com\\/t?e=m%3D2%26s%3DrRcl6iIfzhVw4vFB6t2Z2ueEDrYVVa64yK8Cckff7TVRAdhuF14FMRRBA%2B6kq7Lr1aH1Hk3GeOif5nGvxlR28b8iqH%2F5lqnzPbQarJ22nn%2Bks8Xx9ge2LJ8yQnCH6WE9i63DAi4kPA%2BXlhgVgeBFgQtkyqhBb5%2B4x8PUddoNe3Agw3DTlIZsxpz4CsMBmzq44JOed0Rxa6M5b1wVol%2FpsGkunOkzL8PQmVrGphhu%2FZEahBoPvMeUI8ybej9eVyNc%2FIjZefNyPKOTCpmaT0DBiq%2FY1S%2FD%2B%2BGaYv8Ah3oUTSU%3D&union_lens=lensId:TAPI@1617354106@2108104c_0890_17891d126de_a119@01\",\"selling_point\":\"\",\"coupon_amount\":0,\"elastic_title\":\"填缝剂勾缝施工工具\"}","commodity_id":"3315726366465498216","detail_url":"sslocal://webview?swipe_mode=1&url=https%3A%2F%2Fs.click.taobao.com%2Ft%3Fe%3Dm%253D2%2526s%253DrRcl6iIfzhVw4vFB6t2Z2ueEDrYVVa64yK8Cckff7TVRAdhuF14FMRRBA%252B6kq7Lr1aH1Hk3GeOif5nGvxlR28b8iqH%252F5lqnzPbQarJ22nn%252Bks8Xx9ge2LJ8yQnCH6WE9i63DAi4kPA%252BXlhgVgeBFgQtkyqhBb5%252B4x8PUddoNe3Agw3DTlIZsxpz4CsMBmzq44JOed0Rxa6M5b1wVol%252FpsGkunOkzL8PQmVrGphhu%252FZEahBoPvMeUI8ybej9eVyNc%252FIjZefNyPKOTCpmaT0DBiq%252FY1S%252FD%252B%252BGaYv8Ah3oUTSU%253D%26union_lens%3DlensId%3ATAPI%401617354106%402108104c_0890_17891d126de_a119%4001","goods_json":"{\"original_price\":398,\"price\":159,\"real_url\":\"https:\\/\\/s.click.taobao.com\\/t?e=m%3D2%26s%3DrRcl6iIfzhVw4vFB6t2Z2ueEDrYVVa64yK8Cckff7TVRAdhuF14FMRRBA%2B6kq7Lr1aH1Hk3GeOif5nGvxlR28b8iqH%2F5lqnzPbQarJ22nn%2Bks8Xx9ge2LJ8yQnCH6WE9i63DAi4kPA%2BXlhgVgeBFgQtkyqhBb5%2B4x8PUddoNe3Agw3DTlIZsxpz4CsMBmzq44JOed0Rxa6M5b1wVol%2FpsGkunOkzL8PQmVrGphhu%2FZEahBoPvMeUI8ybej9eVyNc%2FIjZefNyPKOTCpmaT0DBiq%2FY1S%2FD%2B%2BGaYv8Ah3oUTSU%3D&union_lens=lensId:TAPI@1617354106@2108104c_0890_17891d126de_a119@01\",\"shop_goods_id\":\"545946056107\"}","img_url":"FkIf0HgWAfdVmcwh7fmFFVPA9PQc.jpg","item_type":1,"origin_price":"","price":159,"promotion_id":"3315726366465498216","promotion_source":1,"source":"淘宝","title":"德高美缝剂十大品牌美缝胶瓷砖地砖专用填缝剂勾缝瓷缝剂施工工具"} --}
2）质量太差的美缝剂由于环氧树脂的成分加入别的材质以次充好，其与固化剂在一起硬化之后，不久就会出现局部发黑现象。所以美缝剂不能去买贴牌以及小品牌产品。特别是卫生间潮湿区域或者厨房烟机位置，发黑现象尤其明显。{!-- PGC_COMMODITY:{"charge_url":"https://s.click.taobao.com/t?e=m%3D2%26s%3DbS4kXLeYC3Nw4vFB6t2Z2ueEDrYVVa64yK8Cckff7TVRAdhuF14FMRRBA%2B6kq7Lr1aH1Hk3GeOif5nGvxlR28b8iqH%2F5lqnzPbQarJ22nn%2Bks8Xx9ge2LJ8yQnCH6WE96y6ql6r1WfENRDBmE4EfxQtkyqhBb5%2B4x8PUddoNe3Agw3DTlIZsxpz4CsMBmzq44JOed0Rxa6O0Oia%2FXXd2OIq6Jn15cJf7mVrGphhu%2FZEahBoPvMeUI8ybej9eVyNc%2FIjZefNyPKO6S6GJuzUw36UrQxsR54ZV3BHrKKSAw2SiZ%2BQMlGz6FQ%3D%3D&union_lens=lensId:TAPI@1617354106@2127df56_0860_17891d124a6_57ea@01","client_goods_data":"{\"promotion_id\":\"60735254210400\",\"product_id\":\"607352542104\",\"title\":\"东方雨虹美缝剂瓷砖地砖专用厨房卫生间美缝胶勾缝剂防霉易擦洗\",\"cover\":\"https:\\/\\/p1.toutiaoimg.com\\/img\\/cmp-ecom-alliance\\/FuD83d1NHkX_faQnSGNKGryDC6yE.jpg~400x0.webp\",\"price\":3400,\"market_price\":28800,\"cos_fee\":483,\"detail_url\":\"sslocal:\\/\\/webview?swipe_mode=1&url=https%3A%2F%2Fs.click.taobao.com%2Ft%3Fe%3Dm%253D2%2526s%253DveYOngvqTYtw4vFB6t2Z2ueEDrYVVa64yK8Cckff7TVRAdhuF14FMRRBA%252B6kq7Lr1aH1Hk3GeOif5nGvxlR28b8iqH%252F5lqnzPbQarJ22nn%252Bks8Xx9ge2LJ8yQnCH6WE96y6ql6r1WfENRDBmE4EfxQtkyqhBb5%252B4x8PUddoNe3Agw3DTlIZsxpz4CsMBmzq44JOed0Rxa6O0Oia%252FXXd2OIq6Jn15cJf7mVrGphhu%252FZEahBoPvMeUI8ybej9eVyNc%252FIjZefNyPKOTCpmaT0DBiq%252FY1S%252FD%252B%252BGaYv8Ah3oUTSU%253D%26union_lens%3DlensId%3ATAPI%401617354106%400b847693_3bb6_17891d1267c_3af1%4001\",\"sales\":11453,\"item_type\":7,\"cos_ratio\":14.21,\"favor\":false,\"in_shop\":false,\"platform_label\":\"淘宝\",\"h5_url\":\"https:\\/\\/s.click.taobao.com\\/t?e=m%3D2%26s%3DveYOngvqTYtw4vFB6t2Z2ueEDrYVVa64yK8Cckff7TVRAdhuF14FMRRBA%2B6kq7Lr1aH1Hk3GeOif5nGvxlR28b8iqH%2F5lqnzPbQarJ22nn%2Bks8Xx9ge2LJ8yQnCH6WE96y6ql6r1WfENRDBmE4EfxQtkyqhBb5%2B4x8PUddoNe3Agw3DTlIZsxpz4CsMBmzq44JOed0Rxa6O0Oia%2FXXd2OIq6Jn15cJf7mVrGphhu%2FZEahBoPvMeUI8ybej9eVyNc%2FIjZefNyPKOTCpmaT0DBiq%2FY1S%2FD%2B%2BGaYv8Ah3oUTSU%3D&union_lens=lensId:TAPI@1617354106@0b847693_3bb6_17891d1267c_3af1@01\",\"selling_point\":\"\",\"coupon_amount\":0,\"elastic_title\":\"东方雨虹瓷地砖美缝剂\"}","commodity_id":"60735254210400","detail_url":"sslocal://webview?swipe_mode=1&url=https%3A%2F%2Fs.click.taobao.com%2Ft%3Fe%3Dm%253D2%2526s%253DveYOngvqTYtw4vFB6t2Z2ueEDrYVVa64yK8Cckff7TVRAdhuF14FMRRBA%252B6kq7Lr1aH1Hk3GeOif5nGvxlR28b8iqH%252F5lqnzPbQarJ22nn%252Bks8Xx9ge2LJ8yQnCH6WE96y6ql6r1WfENRDBmE4EfxQtkyqhBb5%252B4x8PUddoNe3Agw3DTlIZsxpz4CsMBmzq44JOed0Rxa6O0Oia%252FXXd2OIq6Jn15cJf7mVrGphhu%252FZEahBoPvMeUI8ybej9eVyNc%252FIjZefNyPKOTCpmaT0DBiq%252FY1S%252FD%252B%252BGaYv8Ah3oUTSU%253D%26union_lens%3DlensId%3ATAPI%401617354106%400b847693_3bb6_17891d1267c_3af1%4001","goods_json":"{\"original_price\":288,\"price\":34,\"real_url\":\"https:\\/\\/s.click.taobao.com\\/t?e=m%3D2%26s%3DveYOngvqTYtw4vFB6t2Z2ueEDrYVVa64yK8Cckff7TVRAdhuF14FMRRBA%2B6kq7Lr1aH1Hk3GeOif5nGvxlR28b8iqH%2F5lqnzPbQarJ22nn%2Bks8Xx9ge2LJ8yQnCH6WE96y6ql6r1WfENRDBmE4EfxQtkyqhBb5%2B4x8PUddoNe3Agw3DTlIZsxpz4CsMBmzq44JOed0Rxa6O0Oia%2FXXd2OIq6Jn15cJf7mVrGphhu%2FZEahBoPvMeUI8ybej9eVyNc%2FIjZefNyPKOTCpmaT0DBiq%2FY1S%2FD%2B%2BGaYv8Ah3oUTSU%3D&union_lens=lensId:TAPI@1617354106@0b847693_3bb6_17891d1267c_3af1@01\",\"shop_goods_id\":\"607352542104\"}","img_url":"FuD83d1NHkX_faQnSGNKGryDC6yE.jpg","item_type":1,"origin_price":"","price":34,"promotion_id":"60735254210400","promotion_source":1,"source":"淘宝","title":"东方雨虹美缝剂瓷砖地砖专用厨房卫生间美缝胶勾缝剂防霉易擦洗"} --}
3）美缝剂涂打之后不久就会严重泛白，是因为地面瓷砖缝隙里面水分太多引起。因为卫生间泥瓦工做好后，由于卫生间是装修过程必须用水位置，用水必然会渗水到瓷砖缝隙（局部保护难免会有破损）。如果所有装修工序完毕再做卫生间的美缝，出现泛白现象难以避免。所以卫生间的美缝必须做在泥瓦工完工后，大面积最后施工，才能有效避免卫生间的美缝泛白现象。结语个人观点认为，美缝凹凸状态不均匀是多方面因素引起，其中最为突出的是瓷砖几何尺寸不标准是师傅不能规避的问题，所以瓷砖的选择也特别重要。其次为选择技术过硬的施工团队加上美缝剂质量，才能达成优质的呈现效果。希望此回答能够解除你的疑惑，祝你生活愉快、工作顺利！
