THE DIFFERENCE BETWEEN PLASTERING AND RENDERING
Undoubtedly, this topic will have probably been keeping you awake all night wondering the exact nature of the difference between plastering and rendering – it certainly did us, until we happened on the answer. Well, okay, it did not exactly, and it probably hasn’t occurred to you either, but if you are going to get started on any plastering based DIY task, it pays to know these basics. After all, the last thing you want to do is walk into the DIY store and buy all the wrong things!
We have been there and done that and bought the t-shirt (as well as several other items that we should not have done, either). For a professional service visit http://plastererbristol.net
So, for once and for all, let us at this moment lay to rest the difference between plastering and rendering. In fact, the most basic bones of it can be laid bare in just one sentence. Plastering is done indoors whereas as rendering is outdoor. This is in a nutshell, the essence of it. However, there is more to be expanded on here.
Allow us to continue…
Less cement is used in the preparation of plastering an interior wall, than an exterior one. This is because we want the walls to look lovely and smooth and much more receptive to the paint that you are going to put on them.
Of course, there still may be a degree of difference between the exact composition of the materials used for an interior plastering job, depending on which room it is being used in. You know how you can get different types of paints for different rooms – we do not just mean the colours or the finish here, but the thickness and the consistency. For example, you may use a special paint to paint the bathroom or kitchen area, where there will be steam and condensation. Alternatively, smoke and heat. These paints will be designed to withstand this. Likewise, you may wish to mix the plaster for, say, a bathroom, a little differently to the living room, for the same kind of reasons.
So, as we now know, rendering is the name for the kind of plastering we do on the external walls. Once again, the exact mixture and the amounts of cement may vary depending on just how weatherproofed you need this to be. So one thing you may wish to do is work out which way the wind is blowing – literally! Is your wall north or south facing? Does is get a battering in prevailing storms? The tougher it needs to be, the richer the mix will have to be.
Which can lead us on to our next problem, that of breaking. This is something that needs to be given consideration and one reason why all walls were not created the same when it comes to rendering!
You will also want to think about which materials are the most suitable for the job in hand. Polymer works well for added water resistance whereas acrylic can also boast stamina and versatility of applications, as well. Some acrylics may even be applied by spraying, offer a variety of different finishes and will dry far quicker than some other types.
