Venetian Plastering What is It

ventiona plastering project exampleVenetian plaster is a popular way of describing plasters that were manufactured in the north of Italy and primary in places like Venice. However, most people in this particular industry use the term Venetian plaster more as a technique or style rather than the actual product, and it can also be named marble plaster or polished plaster, although not all finishes are polished up, yes it can get a bit confusing.

A traditional Venetian plaster will be made with lime and marble dust, although lots of the modern-day Venetian plasters are synthetic-based and are made to imitate the appearance of authentic Venetian plasters, however, there are several purists who will exclusively use the traditional lime based Venetian plasters and in the end, it’s really down to what the consumer wants and is willing to pay for.

What’s the difference between Synthetic Venetian plasters and natural lime-based Venetian plasters?

That is a question that gets discussed quite a bit on many communities globally, and of course it has come up numerous times on the plasterers forums. Some feel that nothing is better than using all natural lime-based Venetian plasters, for example, the traditional way of doing things. On the other hand, many others believe synthetic Venetian plasters are better because they are more controlled, and you know how they’re likely to react, but then again, can a traditional Venetian plaster be beaten with quality not to mention the desired look and feel. There’s a good blog on this subject available here.

Venetian plaster is generally an extremely thin finish that you either apply using a small trowel or spatula, and the finish is built up over many layers. These layers are then burnished to create a smooth surface that gives the illusion of great depth and texture. When Venetian plaster is left unburnished it provides a matte finish.

There are lots of Venetian plaster techniques and a few of the ones you may have heard of are marmorino, and scagliola and travertine but the sky is the limit when considering designs and textures… When Venetian plaster is applied properly it can be used to produce a marble like finish as an alternative for the genuine thing when it’s impossible to use the actual marble, For example, making a column out of marble will be very expensive but employing a Venetian plasterer to create the marble effect will be a hell of a lot less, and you wouldn’t be able to distinguish the difference.
If you’re looking for Venetian plastering in the South of England, then I can really only advocate one company, and that is a plasterer in Weybridge named CES Coating. I’ve worked with them a few times over many years and over the years, their business has grown exponentially through word of mouth and repeat business.

What is Wet Plastering?

For licensing purposes, wet plastering refers to the application of a mixture of lime, cement or gypsum plaster and/or sand and water (or other materials to achieve the desired result) for the covering of walls and ceilings internally. Wet plaster is applied whilst wet/plastic, usually by trowel, and will dry and harden after application.

Wet plastering is often referred to as solid plastering and should not be confused with external rendering.

Wet plaster can be applied in numerious situations including (but not limited to) brickwork, stonework and concrete surfaces or to existing board linings.

Pricing For Plastering

If you need plastering work done in your home then the price will depend on exactly what work needs carried out, the location of the job, the type and structure of your property, and the amount of prep work needed. Whilst plastering a straight wall or ceiling may seem relatively straightforward when carried out by an experienced plasterer in Chester, plastering around dormer windows, alcoves and all the other structural features in a home takes much more time and expertise irrespective of the size of area involved.

Pricing for smaller plastering jobs will of course differ from larger contracts too, as the majority of plasterers work on a day or half day rate as opposed to a price per room and if the work mainly consists of patching as opposed to for instance skimming an entire wall or ceiling the price for the job would again be different, in short, each job is unique and will be priced individually. If you have various small patching jobs that need carrying out then it would be advisable to get them all done at the same time, making the work more attractive for a plastering company to undertake.

Essential DIY Plastering Tips

Plaster refers to the material that is applied in wall finishing to produce a surface that is amenable to decoration. Mastering the art of plastering takes years, but with time it is something you can learn to do by yourself if you are keen enough. Therefore you should not expect to produce a smooth, attractive finish after a couple of attempts. Here are a few DIY plastering tips that will help to get on your way to becoming a competent plasterer.

Best DIY Plastering Tips

Plan the job

For a beginner, it is advisable to start small and not to bite off more than you can chew. Therefore do not try to work on all four walls at once since this may sour the whole experience and result in a situation where nothing gets done to a satisfactory level.Try to focus on one surface at a time and leave the bigger walls until last.

It is also useful to assemble the requisite tools before embarking on your plastering DIY project. Some typical tools include hard (or wire) brushes, trowels, cutting tools, mixing buckets and plastering tape.

Practice builds confidence

As a novice, you can benefit from starting in a spare bedroom with a poor finish that needs improvement. This is because successful plastering has a lot to do with confidence and practicing in an area where there is little pressure will stand you in good stead when you start working on the main project. Try to plaster skim over the walls as many times as possible to perfect your skill.

Cement and sand

Using cement and sand works great if you want to improve as a beginner. This is because the mixture takes 24 hours to dry, and therefore you have enough time to experiment and work on your skill.

Area preparation

Preparing the area to be plastered is critical so as to eliminate any unevenness in the final finish. Using a hard brush, delicately remove any dust, loose particles of existing plaster and crumbly material from the surface. This will help you achieve a superb, smooth and durable finish.

After brushing, you also need to give the surface a good washing before applying your primer. This is normally a mixture of water and PVA glue. An initial coat of primer gives a good foundation to your plaster and minimizes the possibility of the wall sucking out moisture which may result in the plaster becoming powdery and brittle and then drying and cracking. You can then apply a second coat of the primer, and this should be moist before application of your new plaster. This will be the bonding surface, and will make the application of a new and smooth plaster easy. It will also make your plaster long-lasting.

Cleanliness

Successful plastering is heavily influenced by the cleanliness of your water and the tools you use. Any little contamination will render the attainment of a perfect finish nearly impossible. Even tiny flakes of old plaster will leave unsightly marks on your hard work. This can be quite frustrating, but can be correctly easily if you observe high levels of cleanliness.

Patience

Many DIY plastering enthusiasts try to make everything perfect the first time. Use our trowel to judge the application process of each stage. Each swipe of your trowel will enable you to assess how smooth your plaster is. It is always useful to undertake a practice run initially in order to get a proper feel of the mixture of plaster that you intend to use.

Focus on flatness

Flatness is key when plastering. Many people focus on attaining a smooth surface and totally forget this. Smoothness will be achieved through repeated skimming so concentrate on making your plastered surface flat.

You should also pay special attention to the corners, which must be completely flat. For internal corners, the right and left corners must be totally flat when you hold a straight edge vertically. Likewise, the top and bottom must be flat when you hold a straight edge horizontally.
For external corners (on outside walls), the angle beads must be straight and should be in line with surrounding frames or walls.

Trowel pressure

Ensure you apply firm pressure on your trowel to eliminate bulges. The trowel must also be held at the correct angle. As a result, the plaster will be pushed across the entire length of the trowel and will be forced into all holes on the plaster surface.
