Plastering - Help For You For A Professional Finish

Plastering is definitely an ancient art which is still in use today. Plaster is known as a natural product, hydrated gypsum, with the chemical formula of CaSO4.2H2O. This dries to the fine white powder which may be mixed with additional water and shaped. It has traditionally been used for interior walls, and to create ornate trims. It is the base for painting technique often called fresco where images are painted while the plaster remains wet. The plaster was often stabilized by the addition of materials such as animal hair, or a base like fabric. Exterior walls can be plastered with powdered limestone (stucco).

Many modern interior walls are made from a pre-formed plaster board often known as drywall or sheet rock. Matched against traditional techniques they are easily installed by nailing to studs or joists and having the joints and nailheads concealed by plastered tape. Alternatively the whole surface can be covered with a thin coat of plaster, called veneering.

Either way, plastering is still a task which may be difficult for the average do-it-yourself-er. It is a specialized skill and for the best work, contractors and homeowners hire a professional to achieve acceptable results. Not only does it require experience to produce a smooth surface, but a plasterer is in a constant race with the speed of the chemical reaction as the plaster dries. To achieve that perfect finish it is a race against time because once the plaster has started to set there is not much which the average guy can do about it.

However, for smaller jobs, like to repair wall or ceiling cracks, or small holes, home repairs may be accomplished fairly easily. Blown plaster, where the plaster has separated from the backing, is tougher, but could be tackled by a serious handyman.

With a full plastered wall, initial coats of plaster are applied with a skimming float, a huge flat-surfaced tool which is held at a slight angle to pull the plaster across a wall. Subsequent coats are added with a technique referred to as float and set. This simply means the next coat is applied and floated (smoothed), and allowed to set. To allow each coat to adhere well, there needs to be a means for it to create a key with the surface beneath. On lath, spaces between the slats allow plaster to ooze between and tightly attach. The following coat will be roughened slightly before it has dried to allow the coat above it to stick tightly, and so on.

To achieve an excellent quality plastering job, it is better to call in a professional, except for those small repair jobs. Unless you’re a specialist or you’ve at the very least done it before and you were happy with your result then my advise to the typical guy is, leave it alone. There is nothing worse than seing a poor plastering job and also it can be costly to have it put right. A professional plasterer will likely be expensive. So far as I am concerned, they are worth their weight in gold.

When I say that I understand how hard it can be to carry out these tasks that I have written about in this article. I’ve carried out these tips to many painting projects over the years but at the beginning when I first started out in the painting trade there was a great deal to learn. For my training I joined a firm called Painters and Decorators London. They taught me everything that I know these days. dreamhost discounts
