A Handy Guide to Plaster Types
Until fairly recently cement plaster has been the most common type of plaster to be applied to both interior and exterior walls. It is usually based on a mixture of Portland Cement, fine aggregates and water. Like Gypsum plaster it initially inhibits the spread of fire well, but unlike gypsum it later becomes brittle and looses it's bond with the wall. It is not as easy to mix and prepare as gypsum and does not have as smooth a finish.
Unfortunately, cement plasters are weak in tension and have very little ability to flex making them prone to shrinkage and cracking. They are not recommended for kitchens and bathrooms as they are not totally permeable to water and can lead to the formation of condensation and moulds.
Interior cement plasters are rapidly being overtaken by the use of gypsum based plasters.
Gypsum has a long history as a building material and is still widely used as a component in many types of interior plaster mixes today. It has the benefit of being worked quickly and easily, is tough and hard-wearing, and is extremely durable.
Gypsum itself is a naturally occurring chalk-like mineral found in layers of sedimentary rock. It is composed of calcium sulfate dihydrate and is formed by the evaporation and replenishment of waters containing calcium and sulfates. Once quarried, it can be dehydrated and ground into a fine powder. When mixed with water it becomes pliable until it hardens, thus providing a good smooth surface to cover brick, block, or concrete walls.
Because it contains approximately 20 percent chemically bound water by volume and is non-combustible, gypsum plaster offers excellent fire protection, an important factor in any home. It also has low thermal conductivity, thus helping to save on fuel bills. Unlike cement plaster, very little heat is produced during the reaction stage with water, so it does not shrink during the drying process, and is less subject to cracking. Gypsum plaster also has good acoustic insulation properties, is moisture controlling and resistant to impact damage. It is vapour free and does not release harmful chemicals whilst it is drying.
The smooth finish of gypsum plaster makes it an ideal choice for smooth, modern interiors. Walls are aligned perfectly level with a flat blemish-free finish. Corners are sharp right angles that make a bold elegant statement.
At Plastering Doncaster we commonly use Flat Venetian Plaster, White Plaster of Paris Dry Mix and Plaster of Paris.
Many older properties in the UK, especially those that were plastered before the last century, are likely to have walls coated in a lime based plaster. Lime is an extremely versatile plastering material that was used as far back as the Roman period. Before the growth of the cement industry in the nineteenth century, quicklime from lime pits was mixed with horsehair and other binders before being applied in layers onto a surface. Traditional lime plaster was gradually superseded by the introduction of cement plasters, but now it is once again gaining in popularity as it's benefits are becoming better understood.
There are many advantages to using lime plasters, the main one being its ability to let the structure underneath breathe. Before modern double-glazing and uPVC was introduced, many houses were constructed with the idea that the draughts flowing through wooden-framed windows and doors would keep air constantly circulating throughout the building. This perpetual movement of air helps to remove internal moisture and prevents damp, and subsequently mould, from forming. Lime mortars assist in this process by being vapour permeable, allowing air to move through the structure of the building and filtering moisture out through the walls. When a modern non-breathable plaster is used in an old property, it seals in the internal moisture causing damp and mould to accumulate, especially if the building also has tightly sealed modern windows and doors. This trapped moisture can eventually lead to serious structural issues in a building, and may cost a great deal of money to put right if it is not dealt with early enough.
Lime also functions as a natural fungicide due to it's high pH value and breathability. Mould and fungus struggle to grow on lime plasters, making it an extremely healthy choice, especially for older properties. Lime plasters are also extremely flexible and elastic, and will easily expand and contract under pressures such as heat and moisture. This means they will not shrink or crack compared to cement plasters, and they require no expansion joints.
Lime plasters have a very low carbon footprint. It is possible to manufacture them on a small scale without the need for large and damaging industry. All other materials involved in the process of making the plaster can also be fully reused with no leftover waste.
There are a few disadvantages to using lime plasters, however. They are trickier to apply, and many plasterers today don’t have the necessary skills required to work them effectively. They also take much longer to dry than more modern products, and these factors unfortunately make lime plasters more expensive to use than Gypsum. However, in recent years several companies have developed improved versions of traditional lime plasters with the addition of plastic polymers intended to make the mix easier to work with. This is creating an increase in the popularity of lime plaster with a subsequent drop in costs.
Plastering Doncaster use the following lime plasters; Breathaplasta, Hydrated Lime Type S and N, Miracle Morta-Lok and Masons Hydrated Lime.
Stucco (Portland Cement Plaster)
Stucco is a specific type of plaster used mainly to achieve decorative effects. Although it is used on both internal and external walls, in Britain the term is usually applied to external stucco only. It is composed of aggregates, a binder, and water, and when applied wet it can be moulded into shapes before it hardens to a dense solid. It is therefore ideal as a sculptural and artistic material for elements such as internal cornices and mouldings, as well as a decorative and protective coating for exterior walls. Stucco was extremely popular in Britain in the Regency period where it was used to disguise exterior brickwork and create the appearance of finely jointed stonework. A good example of this is Carlton House Terrance in London.
Originally made with lime plasters, stucco could be brittle and liable to cracking after a period of time. These days it is now generally made with Portland cement to provide increased strength and durability.

Natural Clay Plaster
These type of plasters use natural clay as the binding material for a mix of aggregates and fibre. Clay plasters give a beautiful, organic and earthy look to a room and despite being made of natural products, are extremely tough and durable.
Used all over the world, clay can be simply dug out of the ground and applied to a wall. But to make life easier there are many pre-prepared clay mixes available on the market, and it is a great alternative to more environmentally damaging plaster products. Clay plasters are incredibly ecologically friendly because the materials are easily sourced and require no large scale industry to produce. They also require minimal processing and contain no synthetic ingredients.
There are no chemical reactions taking place during the setting of the clay and so it can be easily moulded into a variety of shapes and patterns. This allows for a variety of creativity in it's application and can be used by both amateur and professional plasterers. Unfired clay plasters are ideal in bathrooms and kitchens as they will absorb moisture in the air, releasing it again slowly when the air becomes dryer. Clay is also vapour free, meaning there are no toxic chemicals to worry about when it is being applied.
The Future of Plastering
As the needs and styles of our modern buildings change, so the technology of the plastering industry is also continually advancing. In recent years a variety of new and exciting products have been created to make plasters more durable, efficient, and easier to apply. These products often combine the best of traditional materials with the latest scientific discoveries, such as polymers and acrylics, to produce new plasters that look amazing without costing the earth.
Plastering Doncaster have extensive experience in using these products and are happy to advise on their suitability for your particular project.
