There are many options of coving styles available, and your painter and decorator will be able to help you decide on the style and type which suits your project best. The most popular materials used in coving are plaster and polystyrene; both with their pros and cons.
Polystyrene coving has come a long way from the old, Styrofoam style which could be fitted with Pritt stick! Lightweight and easier to install, polystyrene coving come in many shapes and styles and can be fitted quickly by a professional plasterer, painter and decorator, however, may be more costly than the plaster alternative.
Plaster coving tends to be simple, clean and smart, in comparison with the wider variety of options available with polystyrene coving. Usually painted to suite the style of the room, plaster coving can be easily adapted to fit your colour scheme and décor. Heavy and sometimes cumbersome, a professional coving specialist, or coving fitter, or experienced painter and decorator should be brought in, in order to achieve a proper finish.
