Plastering
Patches, full walls, suspended ceilings and decorative finishes, set flat and sanded clean.

Good plastering is the part nobody notices. Walls sit flat, joins disappear and the paint goes on clean. That is the standard on every job, from one patch to a whole shop.
Plastering is where Delta started, and Kosta has been doing it for more than 25 years. A small repair gets the same care as a full room.
We work in traditional and decorative plaster and build suspended ceilings for shops and restaurants, in homes and commercial fit-outs alike.
We work across Bayside, the south eastern suburbs and Metro Melbourne.
What we take on
- Wall and ceiling repairs

What plastering covers
New walls
Sheeted, taped, set in coats and sanded, ready for paint.
Ceilings
Cracked or sagging ceilings repaired, or taken down and replaced.
Patches and repairs
Holes, cracks and damaged sections cut out and patched so the repair does not show.
Suspended ceilings
Framed and hung below the structure for shops, restaurants and offices.
Decorative plaster
Cornices and decorative finishes for period and modern rooms.
Clean finish
The site is cleaned up when we are done, and you walk through the result.
Three kinds of plaster work
Walls and ceilings
Plasterboard sheets are fixed to the frame, the joins are taped and set in coats, then everything is sanded. Done well, you cannot see where one sheet ends and the next begins.
- New rooms and extensions
- Replacing damaged walls
- Covering bare brick
