Plastering vs Rendering

The principal difference between plastering and rendering is very simple; plastering is done on interior surface areas whilst rendering is undertaken on exterior surfaces. More specifically, the key difference between plastering and rendering concerns the combination and materials to be used.

Composition of Material

The basic composition for both plaster and render is broadly quite similar – cement, sand, water and on occasion – lime. When rendering, a coarser, higher proportion of sand is the preferred choice. For plaster work finer sand would be used to ensure a smoother finish.

There exists are a wide variety of premixed renders which can be used on many different applications – some renders such as K Rend – have additives (polymers) which provide more enhanced water resistance and strength which is needed on exterior surfaces. Acrylic premixed renders offer a higher level of resistance to water as well as strength which again is important for exterior surfaces.


Modern day techniques and new skills int he plastering and rendering trade means that different types of finish can be achieved for both internal plastering and external rendering. Rendering will generally produce a coarser finish than interior plaster. Pebble dashing is also a type of rendering.


Top Plastering Tips

There are a lot of things that you can do by yourself today. There is a lot of information available and accessible in this age more than ever before. Whatever your passion is, you can be sure that you will always find good and reliable information on how best to go about it. If you are a person interested in doing plastering either for your own house or as part of your job, there is a little information here that can help you in your work. Plastering is rather a simple but involved process that needs a certain degree of skill. Here are top plastering tips for a perfect job kindly provided by Reskim plastering services in Glasgow.

Best Plastering Tips

Always aim for two coats

The most important characteristic of a good wall is its strength and durability. These two things are not easy to achieve and require a lot of skill. That is why one of the best ways of achieving both is by having a double-coat wall. The first coat should be thin and strong while the upper coat just follows the good foundation laid by the first coat. Having a thin coat for the base is very necessary because it is rather easier to apply pressure on it. This reduces the effort needed to have a thick coat which will require more pressure.

Aim for a flat surface

A lot of people do not concentrate on achieving a flat wall, they are rather preoccupied with its smoothness. This is not the right way to go about it, however. The best way of achieving a good plaster is by applying sufficient pressure on the layer and keeping the focus on its evenness. With a flat surface, it is possible to make it smooth afterward by using a good skimming coat.

Achieving a good skim

A good plaster is complemented with a good finish. The skim coat usually does the job of making a good wall beautiful and smooth. The skim of any plaster should be thin at only one or two millimeters thick. Just like the first coat of the wall, it is very important to apply adequate pressure on the skim coat. Achieving a good skim means that you are able to mix the plaster to a certain degree of smoothness. A good skim should not be thick so that it can flow easily.

Use the right tools

The final and probably most important thing when plastering is to use the tools sufficiently. The trowel, for instance, does most of the job. Achieving a good job with the trowel does not require a lot of technical ability. The only key thing when plastering using a trowel is to apply sufficient pressure and make sure that there are no air gaps left in between the plaster. You also need to have an edging trowel to achieve good corners.

The above factors are the top plastering tips that you will need to do your job. One additional thing to consider when plastering is doing adequate preparation. This involves controlling the suction of the wall to preserve the plaster.
