Wondering why you should choose plastic coving over plaster coving cornice? See below.

For those who aren’t worried about traditional perceptions, there are a lot of benefits of hardened polyurethane (plastic) coving cornice over conventional plaster coving cornice. Hardened polyurethane coving cornice falls into the PVC coving cornice category, which has advanced significantly since the original release of polyurethane coving cornice into the market. It could be argued that if hardened polyurethane coving cornice had been invented prior to traditional plaster coving cornice, no one would have thought to use plaster coving cornice.

Polystrene, hardened polyurethane, and other types of plastic coving cornice are very easy to install. The low structural weight of the coving cornice enables easier handling and installation by a single worker. What’s more, it can be installed in buildings with all types of ceilings. The installation of plastic coving cornice is much faster and the only extras items required are a saw, miter box, and adhesive. Hardened polyurethane coving cornice is much tougher, making it less susceptible to breakage. Since it is plastic-based, there is no risk of cracking, crumbling, or deterioration over time as is the case with plaster coving cornice.

Polystyrene and polyurethane coving cornice is usually supplied primed, which means only one cost of paint is required for an easy finish. Furthermore, as it is plastic, it is completely waterproof, making it a great option for kitchens, bathrooms, and even outside environments.

In contrast, as a result of the heavier weight, plaster and Gyproc coving cornice can not be installed on plasterboard ceilings or suspended ceilings. In addition, the installation of Gyproc cornice coving needs two people and it generally requires pinning. The installation process is a difficult job that takes a lot of time, heavy lifting and additional finishing. Working with plaster and Gyproc cornice coving is very dirty work with considerable dust and water. Refurbishments that require plaster coving cornice are consequently quite problematic. The lengths and joints of plater and Gyproc coving cornice develop cracks as they age. In comparison to plastic-based cornice coving, plaster and Gyproc coving cornice is very absorbent, meaning it needs lots of coats of paint for a nice finish.

Moreover, Flexi cornice coving is part of the plastic cornice coving product range. An expert is needed to install curved plaster coving cornice, but the rubberized Flexi cornice coving option available in the plastic range means just about anyone can install plastic cornice coving on curved walls.

Hardened polyurethane cornice coving is a much higher grade product, but there are still specific use cases for polystyrene coving cornice. The finish is now much smoother, and the ease of installation and low cost make it a great product.
