The use of projection plaster in South Africa is four times faster than conventional plaster, reducing labour and increasing production levels, according to Werner Smith, business manager of plaster at Saint-Gobain Gyproc.
He says Saint-Gobain is addressing the need to improve skill levels by offering machine operators a controllable supply of quality-assured material ready to be applied via a spray-plastering machine.
“Projection plaster enhances speed, efficiency and controlled application of RhinoLite projection plaster one coat, an internationally acclaimed light-weight gypsum levelling plaster.
“It is sprayed directly onto walls, ceilings and columns and dries to a gypsum quality, smooth finish, all in one application. Once dry, it is ready to be painted and needs no priming,” he adds.
Smith says the company developed the technique in response to the demand for quality finishes that can be applied quickly and with minimal specialised skills or training.
“The benefits for large commercial areas are great both for the contractor and the client because the key benefit is consistent quality, speed and cost savings,” he explains.
Additional benefits of the product are that paint can be applied directly to plastered surfaces without the need for a primer. It is suitable for application to brickwork, blockwork, concrete, various heating and cooling systems and polystyrene surfaces.
“It is non-corrosive to metal, wood and glass, and is fire-resistant for up to 30 minutes if applied to a 10mm thickness. Its 97% gypsum content makes it environmentally-friendly and the product meets ISO 14001 standards.
Saint-Gobain Gyproc was approached to provide an alternative fast-track building solution for the construction of the 840 three-bedroom apartments that made up the All African Athletes Village in Maputo in 2011.
“One of the most significant timesavers in the project was the use of the projection plaster methodology,” says Smith.
“Projection plaster machine operators skim-plastered the interior walls and ceilings at a rate of over 450m2 per machine per day. A total of 300 000m2 was constructed for the internal walls and ceilings, and this included the installation of insulation and the plastering. It took just 120 days to complete, using eight projection plaster machines,” he says.
One of the trained and accredited applicators of projection plaster for Saint-Gobain Gyproc, The Monarc Group, is currently using this methodology in the 50 000m2 Mirage Hotel development in Cape Town.
“In addition, there are currently more than 200 000m2 of projects in other parts of the country where RhinoLite projection plaster has been specified, thanks to the product’s speed and finish.”
Saint-Gobain Gyproc is the only company that has developed, invested in and funded modular, mobile plaster units, available on a contractual basis. These units can be used by previously disadvantaged individuals to offer a projection plaster service to the building and construction industries.
“We are currently broadening our portfolio of RhinoLite products, by addressing the express needs of our customer base. From a single product in the 1990s, Saint-Gobain Gyproc will have expanded the RhinoLite stable to over eight products by next year,” adds Smith.
