施工要點

先對(dui)施(shi)工(gong)(gong)物表面做防腐(fu)處理(li)→充分攪拌均(jun)勻防火(huo)涂(tu)料→施(shi)工(gong)(gong)以(yi)(yi)刷涂(tu)為主，施(shi)工(gong)(gong)第一(yi)遍厚(hou)度(du)為0.10-0.15mm為宜，表干后(hou)進(jin)行第二次施(shi)工(gong)(gong)，涂(tu)層厚(hou)度(du)以(yi)(yi)0.15-0.20mm為宜，以(yi)(yi)后(hou)各遍施(shi)工(gong)(gong)涂(tu)層厚(hou)度(du)應控制(zhi)在(zai)0.20mm左右，直(zhi)至達到(dao)規定(ding)厚(hou)度(du)，每次施(shi)工(gong)(gong)時間(jian)間(jian)隔以(yi)(yi)涂(tu)層不沾手為準（一(yi)般(ban)在(zai)18-24小時左右）。

驗收注意

涂(tu)(tu)層當平(ping)整，無(wu)(wu)明(ming)顯(xian)凹陷，粘(zhan)結牢固，無(wu)(wu)粉化、松散和浮漿(jiang)，乳突已剔除，無(wu)(wu)漏涂(tu)(tu)、脫粉、明(ming)顯(xian)裂縫等。用(yong)(yong)0.75～1kg榔頭輕擊涂(tu)(tu)層檢測其強度等，用(yong)(yong)1m直尺檢測涂(tu)(tu)層平(ping)整度。
