Ingasetyenziselwa ukulungisa imingxunya kunye neentanda kwi-drywall kunye ne-plaster. Udaka lwe-drywall luza kwiintlobo ezimbalwa ezisisiseko, kwaye nganye ineengenelo kunye neengxaki zayo. Ungakhetha uhlobo olunye kwiprojekthi yakho okanye usebenzise indibaniselwano yee-compounds ukuze ufumane iziphumo ozifunayo.

Ziziphi iintlobo zeeCompounds ezikhoyo

I-All-Purpose Compound: Eyona Drywall Mud ilungileyo

Abafaki be-drywall abaziingcali ngamanye amaxesha basebenzisa iintlobo ezahlukeneyo zodaka kwizigaba ezahlukeneyo zenkqubo.
