Need to plaster your interior walls but have no clue where to start? Stop. Breathe. And read this rundown on everything you need for creating seamless, smooth finishes with RhinoLite’s comprehensive range of gypsum plasters.
There are two types of plaster:
Levelling plasters are designed to create a smooth finish – “level and plumb”, to use the technical term – on uneven interior surfaces like raw brick or concrete. This plastering calls for a thicker application of the plaster, about 10mm.
Finishing plasters can be divided into one-coat multi-purpose plasters, and skim plasters. A one-coat multi-purpose plaster like Gyproc RhinoLite Projection Plaster One Coat levels and finishes a surface simultaneously. It’s generally applied quite thickly, about 10mm. A skim finishing plaster, like Gyproc CreteStone, is applied to already even surfaces to create a smooth finish. Application of a skim finish is about 3- to 6mm thick, and a fine skim usually 2mm.
There are a few essentials you will need if you want to get started with a plastering project.
A 30-litre plastic bucket will do the trick. Fill with the desired amount of water, then add your chosen plaster and mix thoroughly.
A hawk is held in the left hand with a small amount of the wet plaster, so that you can quickly load it onto your trowel.
The process of ‘floating’ prepares a wall for skimming by creating a smooth surface. It also helps create a fine-textured finish.
This is the tool used to apply your wet plaster mixture onto an unplastered wall and to even out firmed-up plaster.
Whether the plastering project is big or small, here’s what to use when.
The uses: This multipurpose plaster is used for the manual interior plastering and finishing of brickwork, RhinoBoard and concrete blocks.

RHINOLITE PROJECTION PLASTER ONE COAT
The uses: It levels and finishes concrete, brick and board surfaces, using a mechanical projection plaster machine, making it particularly suitable for trade professionals.
The X factor: It plasters faster, creates a smoother finish and reduces costs by saving on time, labour and water.
The uses: It’s formulated for skim finishing of concrete installations, precast blocks and plasterboard surfaces like RhinoBoard, using a steel trowel.
The X factor: It creates a highly polished, smooth-wall surface finish.
Also known as a straight-edge, a darby is usually about a metre long, with two handles. It levels out large areas of plastered walls, ensuring an even surface before applying the skim finish.
So your plastered surface is looking good. Now what? It’s time for Plascon Plaster Primer (UC 56). The formulation acts as a binding and sealing coat on gypsum plaster surfaces. It applies easily with a brush or roller and, what’s more, you can paint over it with a solvent or waterbased topcoat.
