Decorative moldings hi architectural decoration-a thil pawimawh tak a ni a, an sak dan quality hian aesthetics zawng zawng leh durability zawng zawng a nghawng nghal vek a ni. Decorative moldings dahna hian design mamawh a tlin theih nan construction standard kaihhnawih te khauh taka zawm a ngai a ni.
Material thlan leh pawm dan
Decorative moldings hi thil chi hrang hrang hmanga siam a ni a, thing, plaster, PVC, leh thir te pawh a tel. Thil hman tur dik tak chu hman tum dan a zirin thlan tur a ni. Installation hmain moldings te chu surface flatness, crack{2}}free surfaces, leh dimensional tolerances national standards (a tlangpuiin, ±1mm phal a ni) zawm leh awm loh enfiah hmasa phawt ang che. Thing moulding-ah chuan moisture-proofing treatment a ngai a, metal molding-ah chuan environment zawm a nih theih nan rust-proofing a ngai thung.
Substrate buatsaih dan tur
Substrate chu a flat, a nghet a, a hring emaw, a chhe emaw a awm lo tur a ni. Concrete emaw plaster emaw substrate chu a vawt (moisture content 8% aia tlem emaw, a tlukpui emaw) a ni tur a ni a, thing substrate chu a flat leh warping awm lo tur a ni. Substrate a inthlau chuan putty emaw cement mortar emaw hmangin level rawh. Drying hnuah sandpaper hmangin a smooth ang a, installation hnuah moldings-ah gap leh unevenness a awm loh nan.
