Ceiling coving, or crown moulding, decorates the edges of the ceiling where it meets the walls. It is available in various designs and materials. Polystyrene is the cheapest form of coving and is lighter and will not require painting. Paper-coated plaster coving is heavier and must be painted. Plaster coving is the most expensive option and is finished in smooth, brilliant white that does not need painting. Coving is also available in various styles from modern to traditional styles. The kitchen coving project should take less than a day to complete.
Place the coving in the desired place and mark the top and bottom edges on the wall and ceiling. Use the pencil to mark at regular intervals.
Connect the pencil marks using the edge of the spirit level. Remove any loose wallpaper or flaky paint. Scratch cross marks between the guide lines with a craft knife to provide a base for the adhesive.
Measure the length of the coving. Cut the end at a 45 degree angle using the saw and mitre block. Use sand paper to smooth any rough edges. The coving should be cut at angles to allow a smooth joint between two lengths.
Spread an even layer of coving adhesive over the top and bottom of the back of the length of coving, using the filling knife. The coving will be in contact with the wall and ceiling.
Hold the coving in place. Line up the bottom edge with the pencil guide line on the wall. Press the whole length of the coving so the adhesive sticks evenly.
Support the bottom and top edges of the coving with the galvanised nails. Hammer the nails into the wall under the coving. Cover the nail heads with filler when the coving adhesive has dried.
Fill the gaps between the wall and ceiling. Use caulking to fill the small gaps between the edge of the coving and the wall and ceiling. Smooth the caulking with the filling knife or a damp cloth or towel.
Use screws to fix the coving on bowed walls.
Keep the kitchen ventilated when using the adhesive which may produce toxic fumes.
