What is the difference between drywall and plaster?
There are many differences between the two including material size, hardness, density, installation and repairs and cost.
Drywall, also known as ‘plasterboard’, is made of gypsum mixed with water and spread between two large sheets of paper. Plasterboard is used for the construction of interior walls and ceilings.
Comparatively, plastering is one of the oldest building techniques. Plaster is made of lime or gypsum, a white material which hardens when drying and is predominately used for covering ceilings and walls. Plaster is used as a protective cover over stone and brick masonry and can also be used for creating finish looks.
Plaster is a powdered mixture with water to create a paste before application to walls. Often two coats of plaster are required to ensure full coverage.
One of the benefits in specifying plasterboard that it is fire resistant.
Plasterboard is installed by lifting the sheets and attaching them to wall studs. The front side of the drywall is a smooth, even surface which can be easily paint it over. Plasterboard is effective in noise and humidity resistance.
Plasterboard is more stable than plaster doesn’t require high levels of sanding and is easier to repair.
Ready-made GTEK™ plasterboards quickly and easily attach to your walls or studs. The install process is simply measure, cut the sheets to size, fix sheets to wall and fill the joins and screw holes and you’re ready to paint your new walls and ceilings. Once the plasterboard has been secured, fill in the joints ands screw holes with a one of the GTEK™ jointing compounds.
Due to the premium quality of GTEK™, plasterboards rarely crack and are already dry making it the premier choice over wet plaster. For example: GTEK™ Wall is a flat, smooth, blemish-free and monolithic surface that will readily take decorative paints and thin cover finishes. Also offering ranges for specific use such as: GTEK™ Ceiling is a 10mm plasterboard sheet designed specifically for ceiling use, ideal for residential and commercial applications where economy of effort and cost-effectiveness are crucial.
If installed in wet areas and bathrooms, it is recommended to use a specifically designed product for wet areas such as GTEK™ Wet Area which has been developed with a low absorption core for wet area walls in residential and commercial buildings. Suitable for bathrooms, laundries, toilets and cleaning room areas and external ceilings such as alfresco areas.
Another wet resistance option by GTEK™ is a high performance lining technology that provides superior performance in wet and high humidity areas in both residential and commercial projects. GTEK™ Barrier incorporates high performance non-woven fibreglass composite lining on the face and back provides superior moisture and humidity resistance. GTEK™ Barrier has superior abrasion resistance making this product ideal in high traffic areas when not tiled.
Available in WA, GTEK™ Smartwall is a fast and easy installation applied to double brick construction, drywall lining is used instead of traditional plaster. It creates a premium smooth internal wall and low maintained finish that is resistant to settling and cornice cracking that you would typically see with use of plaster.

GTEK™ Sound and Impact ranges provide sound and temperature insulation solutions.
Overall, the installation process for plasterboard is quick and easy with little to no dry time. Plasterboard is less expensive to install and is more user friendly for the end user as you have easily hang shelving and frames on plasterboard.
Plaster is a hard material that creates a durable surface to be painted over, however it is porous and absorbs moisture easily and can make painting more difficult and costly as there would need more than two coats and dry time to achieve your desired look.
Compared to plasterboard, plaster has a slower installation process as dry time and multiple layers of plaster must be factored into the build or renovation.
Thicker plaster can be a good sound proof solution. Although, long term plaster can be prone to cracking which can cause costly repairs.
Generally, plaster can be more expensive to install than plasterboard (drywall).
Overall, plasterboard, is the more convenient options of the two, awarded the most time and cost efficient choice.
