Plaster your walls properly

Nov 10, 2016

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.

THE BASICS

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.

THE TOOLS

There are a few essentials you will need if you want to get started with a plastering project. plaster01

MIXING BUCKET 

A 30-litre plastic bucket will do the trick. Fill with the desired amount of water, then add your chosen plaster and mix thoroughly.

HAWK plaster02

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.

RUBBER FLOAT plaster03

The process of ‘floating’ prepares a wall for skimming by creating a smooth surface. It also helps create a fine-textured finish.

STEEL TROWEL plaster04

This is the tool used to apply your wet plaster mixture onto an unplastered wall and to even out firmed-up plaster.

DARBY

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.
