Trim yog dab tsi thaiv lub tsev. Lub qhov rais casings, qhov rooj puag ncig, fascia boards, yas molding, garage qhov rooj jambs - architectural kab uas muab ib lub tsev nws silhouette. Nws kuj yog ib feem ntawm lub tsev feem ntau raug dej thiab tsawg kawg yog siv tau los kho. Txhua qhov chaw kab rov tav catches nag. Txhua qhov sib koom ua ke yog qhov sib txawv capillary. Txhua lub qhov ntsia hlau yog qhov chaw nkag dej.
Tau ntau pua xyoo, trim yog ntoo vim ntoo yog tib qho kev xaiv. Ntoo rots. Xim ncua lub rot. Repainting ncua nws dua. Thaum kawg lub rot yeej, lub trim tawm, thiab lub voj voog rov ua dua.PVC trim thiab moldingrhuav tshem lub voj voog los ntawm kev hloov cov khoom uas ua rau rot. Kab lus no piav qhia txog yuav ua li cas ntoo ua tsis tau, vim li cas PVC tsis, qhov twg qhov hloov pauv tau them rau nws tus kheej sai tshaj plaws, thiab yuav tsum tau txheeb xyuas dab tsi ua ntej xaj.
I. Peb Txoj Kev Wood Trim Fail - thiab Paint Fixes Tsis muaj ntawm lawv
Ntoo sab nrauv trim ua tsis tau los ntawm peb lub tshuab uas sib xyaw ua ke.
Xaus - nplej wicking.Ntoo yog ib pob ntawm cov hlab ntsha microscopic. Txiav ib lub rooj tsavxwm, thiab cov qoob loo uas raug nthuav tawm ua zoo li ib pob ntawm straw - dej uas tiv tauj nws wicks ob peb ntiv tes rau hauv lub rooj tsavxwm hauv ib teev. Xim seals lub ntsej muag nplej tab sis ua haujlwm tsis zoo ntawm cov ntxhib, ntxeem tau kawg. Cov pleev xim miter sib koom ua ke uas zoo nkaus li zoo meej ntawm kev teeb tsa muaj kev sib haum xeeb ntawm kev txiav xaus hauv kaum yim hli.
Hygroscopic cycling.Ntoo absorbs noo noo los ntawm huab cua thiab tso nws. Qhov kev hloov pauv thoob plaws cov nplej yog li ntawm 0.5% mus rau 2% rau 10% av vaum viav vias. Lub rooj tsavxwm raug ntsia rau hauv qhov chaw thiab tsis tuaj yeem txav mus los ywj pheej, yog li kev ntxhov siab concentrates ntawm cov pob qij txha, tawg cov xim zaj duab xis. Qhov no tsis yog xim tsis ua haujlwm. Nws yog ntoo- teeb meem txav uas tsis muaj xim tsim los daws.
Cov kab mob fungal tshwm sim tom qab lub paj.Cov kab mob lwj yuav tsum tau noo noo tshaj 20%. Thaum cov xim tawg ntawm qhov sib koom ua ke - uas nws yuav - dej nce mus txog ntoo hauv. lwj propagates invisibly rau xyoo. Lub caulk zoo li qub los ntawm sab nraud. Ntoo sab hauv yog softening. Los ntawm lub sij hawm ib tug ntsia hlau nkag mus rau saum npoo, rot extends zoo tshaj qhov pom kev puas tsuaj.
Txhua hom tsis ua hauj lwm accelerates lwm ob. Xaus- nplej wicking xa dej. Hygroscopic cycling tawg cov xim barrier. Kev lwj siv cov ntoo tsis sib haum. Tib txoj kev los nres lub voj voog yog tshem tawm cov ntoo.
