Plaster Coving Installation - Fitting Plaster Coving
This is the third video in a series of Quick Coving Tips that explain how to fix plaster coving and plaster cornice.
A professional plaster coving installer describes the process of plaster coving installation or how to fit plaster cornice. After measuring and marking up a room the coving is then ready to be fitted.
First take a surform (surface forming tool - a perforated metal grater which is a cross between a rasp and a plane) and run it down to wall and ceiling members (edges) of the coving. This removes any sharp edges and reduces the risk of cutting yourself during fitting.
Apply coving adhesive to both the top member and bottom member with the Small Tool, dabbing it along the edges. The coving is then pushed into place on the wall paying attention always to stay within the chalk line marks made during the measuring stage.
The cornice is then held in place while the adhesive goes off (sets) either by tacks /pins, or by countersunk screws through the cornice. Once in place any excess adhesive is scraped off using a busk/scraper before the next piece of cornice is fitted. Extra adhesive is added to mitres and joins before fitting the next piece to prevent cracking later.
Don’t worry if there are gaps between the cornice and the wall or ceiling after fitting, as these will be filled with Plaster of Paris (casting plaster) during the filling stage of installation. Clean off excess adhesive as you go with a busk/scrapper and then brush down the surface using a wet brush and the cornice is ready for filling. It is important to wipe off excess adhesive as you go and not to let it set on the face of the coving.
