When to trowel plaster is crucial to ensure a smooth finish. Troweling plaster should be done gently, without applying too much pressure. Using light pressure will help remove any brush marks. Lightly trowel corners that have been left unpainted. If the plaster is too wet to be troweled out, it should be left until the next step. This article will explain the correct way to trowel plaster. You can read the other articles in this series to learn more about how to use the various trowels. Flexible trowels The flexibility of a flexible trowel is the key to a cracking finish. Using a stiff trowel for flattening plaster requires a higher degree of effort than using a flexible trowel. While a standard trowel is an essential tool for plastering, it is usually made of a heavier alloy and has a longer breaking period. While this tool is lighter than a traditional trowel, it does not provide the cracking finish you're looking for. In this video, Armand Paul Hoafat explains the principles behind the Venetian method of plaster application. To create this look, a Venetian trowel should be used. Its blade is flexible and curved at the corners. It's lightweight and helps prevent wrist strain and burn marks. In addition, the Venetian trowel's flexibility makes it the perfect choice for marmorino plasters. Using a square application trowel is another good option. The blade is slightly flexible, and it works well for applying thin plaster on drywall or to finish a thin plaster over a base coat. Another option is stainless steel, which reduces rusting and is better suited to gypsum plasters. A good quality plastering trowel can last for years if cared for properly. The Elite Series XtremeFLEX finishing trowel is made of premium stainless steel and is one of the lightest available on the market. It has a smooth blade with no exposed rivets along the bottom. Its machine finished blade edges help provide a smooth finish to the plaster. Flexible trowels can also be useful for finishing drywall. The best ones feature stainless steel construction, which prevents rust. Triangular trowels Unlike traditional trowels, triangular trowels are ideal for use in tight spots, where the blades of the conventional version won't fit. Masons and stucco plasterers use smaller pointing trowels for small spaces, while larger pointing trowels are ideal for large areas. Always choose the right size for your project, as the trowels come in different sizes, from small to large. You can choose between two basic types of plastering trowels. There are standard steel trowels, as well as steel, plastic, and wood trowels. Stainless steel trowels are more durable and offer more flex. However, they require breaking-in and can develop rust over time. If you're worried about rust, you can get pre-worn stainless steel trowels that feature machine-worn edges. Finally, there are pre-worn gold trowels, which are the most expensive but offer the longest life and highest performance. Another type of trowel is the pointed trowel, which is useful for spreading mortar on top of bricks or blocks. You can use it to check whether mortar between chimney bricks has cracked, and if it is, it needs to be repaired. Pointed trowels are made with flat, smooth edges on two sides, and have notched edges on the other side. They can combine different materials, and are usually used for adhesives and mortars during wall installations. Jigane Among the many uses of a plaster trowel, the polished one is most often used for deep compression and surface smoothing. While a steel trowel only compresses the surface, the Jigane trowel pushes the plaster deep into the wall, resulting in a much fuller finish. Before using a Jigane trowel, be sure to check its edges with 1000-grit sand paper to eliminate any micro-scratches. Most factory-made jigane trowels are stamped from steel and fitted with handles, but Sugita-san crafts a variety of styles of these tools, making each one unique and special. While forged jigane trowels are a coveted item among plasterers, hammered jigane require a great deal of extra work. The iron is heated, distorting its shape. To use a jigane trowel, start by preparing the area where the plaster will go. If there are areas of roughness, you can trowel them to smooth out the surface. To flatten a first coat, start at a corner and work your way outwards. Remember to hold the leading edge of the trowel 10 to 15 millimeters away from the wall. After the plaster has dried, you may want to smooth out any bulges. Abarayaki When to trowel plaster Abarayaki? If you are using a wooden trowel, make sure you have prepared it properly. You should be able to handle the tool with ease and use it to create a smooth surface. However, if the material is already too hard, you may have trouble achieving the desired result. A good way to remedy this problem is to use a smaller trowel, which has a softer quality than a regular plaster trowel. To apply a first coat of plaster, hold the trowel at an angle to the wall. With the long side of the trowel flush to the wall, push the plaster along the surface, flattening out the edges of the first layer of plaster. Make sure to use firm pressure while pushing the trowel across the surface, avoiding bulges and marks. The first coat should be flat and with no bulges, as the plaster will be smoother with each pass. To apply cement or lime based plasters, the primary application trowel is used. If you are using a cement mortar, use the Honyaki, which is a steel plate. The Honyaki is thin, but has a high hardness level. It is useful for plaster applications in difficult areas. While it may not be as flexible as an abarayaki, it is still recommended. There are some other types of trowels for use on plaster. Scrim tape It is best to use scrim tape when troweling plaster for several reasons. This tape can allow for movement below the skim coat and can prevent the plaster from cracking during the drying process. It can also be used to cover visible cracks or joints between boards or sections. Using scrim tape when troweling plaster will keep your home's interior dry. And while it is not as powerful as other adhesives, it will prevent your plaster from falling off while troweling it. Before you start applying plaster, make sure that it's still in date. Don't forget to close up plaster bags that are half-used. Out-of-date plaster will go off faster and take longer to flatten. Also, remember to use scrim tape to reinforce weak areas. Use scrim tape to protect joints and corners, as well as any areas where the plaster is prone to cracking. The tape will also prevent any lines that may show up in the future. When troweling plaster, keep in mind that you shouldn't fill the trowel too much. Too much plaster will drag through the scrim tape and ruin the finish. If you overfill the trowel, the plaster will end up on the floor. Try to find the perfect amount of plaster for each coat. Remember, plastering walls is a difficult job, so take your time and don't rush. Start by applying a thin layer of plaster on the wall, which should be about 2mm thick. Once the first coat is applied, you can apply a second coat to cover any uneven patches. Size of trowel The size of the trowel is an important consideration when troweling plaster. A finish trowel is used to smooth the plaster surface after the base coat is applied. A finish trowel's blade is cross-ground, so it will hold its shape better than a plain one. The handle is also curved, such as the Camel Back pattern or California pattern, to help the user hold it comfortably. Each handle is machine-fitted to a milled shank. If you plan on troweling the wall yourself, you can start with a smaller trowel to get the hang of the process. Larger trowels are useful for larger sections, but their weight and size can cause hollow areas on the wall. For beginners, smaller trowels will be more suitable to start with. If you are not sure which size to buy, ask an expert. A good hardware store will carry four or five sizes, so you can choose what's right for you. A steel trowel is similar to a hand float, except that it is sturdier and narrower. The hawk is an open square that tapers hold in their opposite hands. Hand trowels can range from nine to sixteen inches in diameter, but you should also consider the type of handle. Some trowels have a knob handle on the underside. You'll need a narrow-bladed trowel for final finishing.
