Plaster Finish

Plaster wall finishes generally last longer than paint jobs or wallpaper do; after plaster dries, it hardens, stone-like, similar to its original form as raw limestone or gypsum. In addition to wall finishes, plaster today is often used to construct surfaces that need to be hard, such as a squash court.

Rough Plaster

Rough Cast Plaster: Rough cast plaster is composed of sand and gravel in a specific proportion and is applied over a freshly plastered surface. The base of plaster consists of two coats under a 12 mm thick layer and a top layer with thickness of 12mm in a cement mortar ratio 1:3.

Finish Plastering

Finish Plaster is a mill-mixed lime/gauging finish plaster that requires only water to achieve a high-quality plaster lime/finish with easy troweling characteristics. It is designed for finishing conventional and veneer plaster interior surfaces. Offers a setting time of 60-70 minutes with excellent working conditions.

Wall Finishes Plaster

Plaster wall finishes generally last longer than paint jobs or wallpaper do; after plaster dries, it hardens, stone-like, similar to its original form as raw limestone or gypsum.

Wall Plaster Material
