Plaster Finishing

Getting a professional Plastering Finish

Plasterwork or plastering has been used as a building technique for centuries. The pyramids of ancient Egypt have plasterworks that are made of calcined gypsum more than 4,000 years old. Greek and Roman ruins have evidence of plastering that could have been lime plaster.   A lot of architectural masterpieces especially during the Gothic period have superb plastering that have stood the test of time.

What are the types of plaster?

There are two general kinds of materials for plastering: gypsum based and cement based. Gypsum based plastering are used for interior finishing while the cement based plastering is for exterior finishing. Gypsum based plasters are susceptible to moisture and damp so cement based plastering can be used on interior walls that are prone to moisture and for interior walls that need thicker plastering. The common gypsum cement plasters are:

Note that plaster works on indoor walls only. Take precaution when mixing water and plaster. Use clean water and add plaster to the water and not the other way around

DIY is a leading pastime in the UK today. For those who are not well-versed on the art of plastering (yes, it is an art) here are some information that might prove useful to you.

What plaster to use for what particular surface

Before you buy your plastering material, make sure that you but just the right amount for plaster ahs a very short shelf life.  A rough guide in estimating is a 10 kg plaster should be enough to cover 1.5 square meters at 10 mm thick. The same amount would be enough to cover 5 square meters of 3 mm thick plastering.

Skimming a Wall

"Skimming" means plastering a surface to make it smooth. It is actually the top coat or finishing coat of a wall.  What is quite challenging in skimming is the fact that plastering materials dry quickly. Don't get frustrated if you can't do a great job at first. Skimming is quite challenging and it is to your advantage if you don't take on a big job at first. It is ideal to mix a batch that you can finish before the plaster hardens. Practice on some spot until you think you have gotten into the groove of skimming. If you have wasted packs of plastering without improvement, best if you call in a professional.

Here are some rules to follow when skimming a wall.

Leave the wall to dry for a day or so.
