防(fang)(fang)水(shui)涂料使用(yong)年限到(dao)期后(hou)，如(ru)何重新(xin)涂刷：準備(bei)工(gong)(gong)作(zuo)：清(qing)理(li)(li)(li)舊(jiu)防(fang)(fang)水(shui)層(ceng)(ceng)：首先要清(qing)除已失效的(de)(de)防(fang)(fang)水(shui)涂料層(ceng)(ceng)。如(ru)果防(fang)(fang)水(shui)層(ceng)(ceng)表(biao)面只是(shi)輕微損壞，如(ru)局部(bu)粉化或小面積(ji)剝落，可以使用(yong)工(gong)(gong)具（如(ru)、鋼絲刷等）將損壞部(bu)分小心地刮除。對于(yu)大面積(ji)失效的(de)(de)防(fang)(fang)水(shui)層(ceng)(ceng)，可能需要使用(yong)高壓水(shui)沖洗或借助(zhu)化學清(qing)洗劑來去除舊(jiu)涂層(ceng)(ceng)。在(zai)清(qing)理(li)(li)(li)過程(cheng)中(zhong)，要注意盡量(liang)不損傷基層(ceng)(ceng)表(biao)面，哈(ha)密防(fang)(fang)水(shui)乳化瀝青涂料，因為基層(ceng)(ceng)的(de)(de)平整度和完整性會影響(xiang)(xiang)新(xin)涂料的(de)(de)施工(gong)(gong)效果。例如(ru)，在(zai)清(qing)理(li)(li)(li)衛生(sheng)間舊(jiu)防(fang)(fang)水(shui)層(ceng)(ceng)時，防(fang)(fang)水(shui)乳化瀝青涂料訂購，要先將瓷磚縫(feng)隙中(zhong)的(de)(de)舊(jiu)涂料清(qing)理(li)(li)(li)干凈，避免殘(can)留影響(xiang)(xiang)新(xin)涂料與(yu)瓷磚的(de)(de)粘結。

防水涂(tu)(tu)料使(shi)用(yong)(yong)(yong)年限(xian)到期后，如(ru)何重(zhong)新(xin)涂(tu)(tu)刷(shua)(shua)：施(shi)(shi)(shi)工(gong)(gong)過程：施(shi)(shi)(shi)工(gong)(gong)方(fang)式：根據涂(tu)(tu)料的類(lei)型(xing)和(he)施(shi)(shi)(shi)工(gong)(gong)要求(qiu)，可(ke)以采用(yong)(yong)(yong)刷(shua)(shua)涂(tu)(tu)、滾涂(tu)(tu)或噴涂(tu)(tu)的方(fang)式。刷(shua)(shua)涂(tu)(tu)適用(yong)(yong)(yong)于小面(mian)(mian)積(ji)(ji)、細節部位(wei)的施(shi)(shi)(shi)工(gong)(gong)，如(ru)陰陽角(jiao)、管道周(zhou)圍(wei)等(deng)；滾涂(tu)(tu)適合大面(mian)(mian)積(ji)(ji)的平面(mian)(mian)施(shi)(shi)(shi)工(gong)(gong)，能夠保證涂(tu)(tu)層厚(hou)度相對均勻(yun)；噴涂(tu)(tu)則可(ke)以提高施(shi)(shi)(shi)工(gong)(gong)效率，適用(yong)(yong)(yong)于大面(mian)(mian)積(ji)(ji)的屋(wu)面(mian)(mian)等(deng)區域。例(li)如(ru)，在重(zhong)新(xin)涂(tu)(tu)刷(shua)(shua)衛生間墻(qiang)面(mian)(mian)時，先用(yong)(yong)(yong)毛刷(shua)(shua)將陰陽角(jiao)處仔細涂(tu)(tu)刷(shua)(shua)，防水乳化瀝青(qing)涂(tu)(tu)料多少錢一桶(tong)，然后再用(yong)(yong)(yong)滾筒進行大面(mian)(mian)積(ji)(ji)的滾涂(tu)(tu)。

防(fang)水(shui)(shui)(shui)涂(tu)料的(de)特點(dian)：優良的(de)防(fang)水(shui)(shui)(shui)性(xing)(xing)能：防(fang)水(shui)(shui)(shui)涂(tu)料經固化(hua)后形成(cheng)的(de)防(fang)水(shui)(shui)(shui)薄(bo)膜具有一定(ding)的(de)延伸性(xing)(xing)、彈塑性(xing)(xing)、抗(kang)裂性(xing)(xing)、抗(kang)滲性(xing)(xing)及耐候(hou)性(xing)(xing)，防(fang)水(shui)(shui)(shui)乳化(hua)瀝青涂(tu)料批發(fa)價，能起到(dao)防(fang)水(shui)(shui)(shui)、防(fang)滲和保(bao)護作(zuo)用。良好的(de)溫度(du)適應性(xing)(xing)：可(ke)在常溫條件下(xia)形成(cheng)連續整體的(de)、具有一定(ding)厚度(du)的(de)涂(tu)料防(fang)水(shui)(shui)(shui)層。操作(zuo)簡便：防(fang)水(shui)(shui)(shui)涂(tu)料易于施工(gong)，可(ke)以采用刮涂(tu)、滾涂(tu)等多(duo)種施工(gong)方(fang)法(fa)。易于維(wei)修與維(wei)護：防(fang)水(shui)(shui)(shui)涂(tu)料形成(cheng)的(de)防(fang)水(shui)(shui)(shui)層在出現破損時，容(rong)易進行局部修補和維(wei)護。
