Lime Plaster vs Gypsum Plaster
One of the main types of plaster is based on lime and gypsum. Lime plaster is made with a combination of sand and slaked (hydrated) lime, while gypsum plaster is generally made with a combination of sand and gypsum. Both offer a traditional, attractive look and come with advantages and disadvantages.
Lime plaster is highly durable and breathable, meaning it can keep moisture levels balanced and protect walls from water damage. On the other hand, it takes a long time to set, which means it is mostly unsuitable for damp conditions. Gypsum plaster is much faster to set, making it ideal for modern properties or those with a problem with dampness. However, it isn't as hard-wearing as lime plaster and can become brittle if exposed to too much moisture.
What are the pros and cons of cement plaster?
Cement plaster is another popular choice, being quick to apply and able to create a flat, even finish. It also works well with other materials, such as brick and stone, and is very resilient in wet weather, making it ideal for outdoor walls. On the downside, the lack of flexibility could mean the finish is prone to cracking and not as forgiving with changes in temperature as other plasters. It can also be difficult to apply evenly, so it is best left to experienced professionals.

Should I use Venetian Polished Plaster?
Venetian polished plaster is an increasingly popular choice in the home. It has a unique pebble-like texture and is available in a variety of colours, making it great for creating bold, feature walls. It is strong, resilient and well-suited to almost any environment. On the downside, it can be expensive and more time-consuming to install than other types of plaster.

The plaster topcoat is used to give a smooth, polished finish to the walls. It is typically made from a combination of lime and gypsum, or with a combination of cement and sand. The topcoat will need to be applied by a professional, as it requires considerable skill to ensure the mix is consistent and applied in the correct way. Once applied, it forms a highly durable, waterproof surface, allowing you to enjoy the perfect interior finish.
