Plastering is the foundation for every finish that follows in a renovation or extension — paint, fixtures, cabinetry, all of it sit on top of your plaster work. Getting it wrong means visible seams, cracking, and a paint job that never quite looks right. This guide walks through the plastering process from stud walls to smooth finish, where it fits in your build timeline, and the mistakes worth avoiding. Built 4 Constructions handles wall plastering Melbourne homeowners rely on for new extensions and renovations across Frankston, Mornington, Narre Warren, and the surrounding south-east suburbs — coordinated with our carpentry and painting teams so nothing gets missed between trades.
