Marblesheen finishing was a very popular surface of choice in Australia particularly between 1970 – 1990. The marblesheen surface is a mixture of cement and crushed marble and applied using a trowel. The thickness of a marblesheen surface is typically between 5-25 mm, and because of its soft, porous characteristics it tends to wear down over the years.
Common issues we find are with marblesheen include:
- ‘Drummy’ areas where the surface has become soft and week, separating from the concrete behind.
- Black spots and rusty patches (concrete cancer) caused by rusted reinforcing material breaching the surface.
- Calcium build-up and residue.
- Surface cracks.
In order to complete this project we took the following steps:
- Drained pool and removed hydrostatic valve.
- Completed a thorough assessment of the pool’s surface looking for ‘drummy’, soft and weak areas.
- Removed and replaced ‘drummy’, soft and weak areas.
- Removed and replaced all rusted areas.
- Grind the surface smooth removing all black-spots, algae, and calcium build-up.
- Seal the surface with primer coat (vinyl ester resin).
- Applied fibreglass surface.
- Applied filler coat (vinyl ester filler).
- Completed one final grind to render surface smooth.
- Applied top coat (Aquaguard Technology).
