  • Polystyrene coving
  • Coving adhesive
  • Tack nails (small nails)
  • PVA glue watered down
  • caulk
  • scrap piece card


  • Find the depth of your coving on the packet and mark on a piece of card.
  • Hold up the marked card along the top of the ceiling, then mark the walls where the pencill mark lies. Repeat in regular intervals and do the same with the ceiling.
  • Hold up a straight edge, such as a spirit level and meet the lines with the majority of them. Although ignore the spirit level bubble.
  • Hammer in the tack pins/nails along my bottom pencil mark all the way around the room.
  • Next, if you have a painted surface, brush all over the coving area with PVA solution and leave to dry. Note, you may need to remove any loose bits of paint or plaster for good adhesion before this.
  • Then, using a coving cutting tool and preferably a scalpel, cut your mitred corners. To see how I do it, refer to the video below or read the notes above.
  • Once cut, gently fold the cut away and sand with fine sand paper to remove any burrs to reveal a clean cut.
  • Run over the back of your coving with Everbuild’s Coving Adhesive and press on to the wall while resting it on the nails. However, leave a couple of millimetres gap in the mitred corners for easy fitting your next corner later.
  • If your wall is too long for the coving, then work on your opposite corner with a new piece and mark where it starts to overlap. Then draw a straight line with a speed square and cut with a fine tooth come.
    NOTE: if you want to be perfect with invisible joins, you are better also making these mitred cuts too, but for ease, I went for straight.
  • Continue all around the room until finished. If you have any pipes, then also read the notes above.
  • Leave to set overnight and remove all the nails.
  • Then fill any gaps and along the top and bottom of the coving and remove with a wet finger or decorator's wipes. Note, it's best to focus on a small area at a time.
  • If you haven't painted your walls yet, masking tape the wall, then paint the coving with white emulsion and leave to dry.
