Plastering the Garage Conversion
Before plastering can commence dust sheets were laid to protect the new flooring from debris and spillages. All holes were covered (ceiling lights and plug socket holes). Gaps between plasterboards were also taped offering a flat platform for the new plaster.
PVA was then inserted over all plasterboards creating a bond between the layers of plaster. This was diluted to a ratio of 1:4 (1 part PVC to 4 parts water), this is rolled on as a PVA glue.
The first layer of plaster is then coated using a hawk board, trowel and float. The plaster is placed onto the hawk board using the trowel, then the float is used to force the plaster from the hawk onto the walls. Plastering is an extremely skilled job so we only use the best plasters in Peterborough.
Once all of the walls are plastered then skimming and smoothing is required. We normally wait for around 20mins to allow the first coat to settle before skimming. This is where we get rid of any lumps and bumps providing the perfect finish. A wet brush can also be used around the edges ensuring a smooth finish.
The surface can then be scraped before a second coat is added. This is achieved using a devilling float. The second layer is then applied which is a thin smooth layer of plaster approximately 2mm thick.
A spray gun is then used to polish up as a finish look. A trowel is used to smooth the surface. A float is then used ensuring a smooth flat finish.
