Every house needs to have smooth, flat internal walls and ceilings, and plastering contractors are the right people for this task. When it comes to houses with walls made of concrete blocks, plasterboards can cover the walls’ imperfections and are much easier to decorate and paint.
The ancient craft of applying plaster by using a thick layer of backing plaster covered by a layer of finishing plaster is rare today. There are many disadvantages of using this technique simply because you are introducing a wet kind of material that dries relatively slow. Thanks to the progresses of technology, we can still enjoy the benefits of plaster without the lowdowns. Plasterboards combine the raw material with the innovation of the current technology, bringing many benefits to plastering contractors and homeowners.
* Smooth, flat and easy to decorate, plasterboards have become popular in the past years.
Plasterboard is made of Gypsum compressed between two sheets of heavy paper. Today, it has become the most common material used for wall and ceiling finishes. There are many sizes and thicknesses of plasterboard, enabling plastering contractors to use it for various projects. Moreover, special kinds of plasterboard can be used to insulate the house and improve the overall thermal properties. If you want to use plasterboard into the bathroom, you can choose waterproof plasterboard, which is very resistant to high temperatures, water and steam.
Plastering contractors deliver even more than a nice design, because plasterboards can sound proof the house, maintain the heat and block the fire. Here are two common types of plastering used today:
1. Dry lining refers to large flat plasterboards installed using several techniques: screwing, bonding directly to the wall or nailing. Dry lining is easy, but requires skill and coordination in order to get a good-looking finish.
2. Plaster skimming is a final smooth coating applied at the end of wet plastering or dry lining. The plaster skim is very thin, about 2 or 3 millimetres and it requires a lot of work and experience for obtaining a perfect finish.
When it comes to price, plastering contractors will charge you different amounts. Plaster work can be quite complex, so it is hard to establish a set price per square feet for example. Some plastering contractors will charge you per work day, while others will assess the entire amount of work that needs to be done and will offer you a quote.
* The services of plastering contractors can cost around £150 – £250 for one day of work, but the price can depend on the type of materials used.
* Standard 1200 x2400x9.5 mm square edged plasterboard can cost around £5.
* According to recent studies, plastering work can cost up to £4000 for an average house.
You can compare prices by browsing the Internet or by contacting some plastering companies in your area asking for quotes. From this point further, all you have to do is choose the most convenient offer and start renovating the house.
How To Plaster Onto Plasterboard In 7 Easy Steps
Tools required: Large bucket, gauging trowel, Electric Mixer Drill, Spot Board, Finishing Trowel, Hawk and 1" and 4" clean paint brush. Materials: Bag of Board Finish Plaster or Multi-Finish Plaster, Clean Water.
1. Having applied scrim tape to the joints and nail heads of the wall that you are about to skim, mix the correct amount of plaster to a smooth creamy consistency. Having pre wet the spot board pour the plaster on to the spot board.
2. Having also wet your hawk and trowel, now load the plaster on to the hawk. To transfer the amount of plaster from the hawk to the trowel pass the trowel over the plaster on the hawk and "squeeze" the plaster onto the trowel creating a "sharp" wedge of plaster on the edge of the trowel.
3. Dividing the wall into three horizontal sections is a easy way when learning to apply plaster to the wall, start plastering at the top left (Note: if you're left handed start at the top right) of the top 1/3 of the wall moving across to the bottom right of the top 1/3 of the wall. Apply an even coat of plaster across the area of about 3mm in depth. Once you have covered this top 1/3 move down and repeat the process on the middle third. Once this is covered repeat on the bottom 1/3. This process or "pattern of three" will enable you to maintain control of the wall and predict the way in which the plaster will go off. It also helps you to know where you started using a new mix if you run out of plaster half way through a wall. Now smooth this first coat so that edges and corners are "sharp" using the wet small brush or edge of the trowel. Also, now smooth the wall following the "pattern of three" to a relatively smooth finish.
4. Now make a second mix of plaster and apply. This is the laying down coat. The first coat was called the roughing on coat. Follow the exact same "pattern of three" and this time aim for a smoother finish but without delaying the process of getting the entire wall plastered. Always remember that plaster will only remain workable for between 10 and 20 minutes prior to putting it on the wall.
5. Once you have covered the wall you can now do a first trowel on the wall to get it smooth. Again follow the "pattern of three",making sure holes are filled in and lines flattened. This is really your last chance to get the smooth finish that you require removing large lines and holes.
6. The next step is to trowel the wall in three sets of three trowels. The first set of three trowels is when the wall is becoming firm and you should trowel the wall with single stroke of the trowel three times. Up to 15 minutes later and using a moist 4" brush, brush the wall ahead of the trowel during the 2nd set of three trowels. This will help to lubricate the passage of the trowel over the drying plaster and prevent dragging.
7. Now up to 40 minutes later when the wall feels as hard as it does when set you can use the same technique as the 2nd trowel above to give a final finish to the plaster. This set of three trowels is done in the "pattern of three" and enables you to maintain a consistent finish across the wall. The final finish should be dull in appearance yet smooth to the touch.
