In this article, we'll discuss some of the methods available to accelerate the drying process. Arxell Drying Systems deliver targeted, controlled drying, which creates the perfect environment for plaster to dry. Using a dehumidifier and applying PVA glue to the surface will help to prevent cracks from forming. A few other methods can speed up the process, as well. Listed below are some of the more popular methods. Mist coat prevents moisture from being sucked out of the plaster Applying a mist coat is an important step before decorating. Make sure that you use water-based paint that is emulsion in consistency. Avoid glossy or vinyl paint, which will not bond with the plaster and will peel off over time. Oil-based paints will not breathe properly and will lead to damp patches in the future. To prevent this from happening, you should first apply a mist coat on a small patch of plaster before applying it to the entire wall. After applying the mist coat, you should apply a primer to the plaster. You should then apply a second coat of paint. It is best to apply more than one coat to get an even finish. Apply a mist coat on freshly plastered surfaces before applying a topcoat. It is important to stir the mist coat often, as it can easily be absorbed by the plaster. Remember not to apply a mist coat over the same spot as it may cause a hairline crack. To apply a mist coat, you will need to water down a paint. A mist coat can be made by mixing 50 percent emulsion with water and applying it to the plasterwork. However, the mixture will make a mess, so you should use dust sheets to protect the newly-applied plaster. It is usually applied in one coat but you may have to apply another coat if the plaster soaks up the first one quickly. It is easy to mix a DIY mist coat. Mix a water-based paint with plain water to create a mist coat. It is important to follow the instructions on the container to ensure that the paint penetrates deep into the plaster and forms a smooth finish. Mix the mist coat with four parts paint to two parts water. The paint should be mixed in a bucket so that there is room for stirring. If you can afford it, use a microporous paint. These paints contain a polymer mixture that lets the plaster breathe and dry easily. Microporous paints will cost a bit more than the emulsion, but they will skip the mist coat step. However, they do not cause as much mess as emulsion, and will not create a thin mix of paint. Arxell Drying Systems provide controlled, focussed drying to create the ideal environment for drying out plaster Plaster is an excellent example of a material which benefits from the constant control of temperature and humidity. It will dry faster if it is heated, and it will be less likely to crack if it is dehumidified. Natural plasters, like lime and clay, have a high moisture content, so their drying process will not affect the surrounding building materials. High humidity levels can cause a variety of problems in buildings. High humidity increases the risk of condensation, particularly on cold surfaces. It can also result in the growth of mold and fungi. Moisture buildup may also lead to rot and other structural issues. Drying out plaster requires a careful approach to ensure a long-term, healthy home. Using a dehumidifier Using a dehumidifier can speed up the process of plaster drying. Plaster has a standard drying time and rapid moisture withdrawal will result in cracked plaster. This is often caused by the plaster cracking during the natural drying process or by the movement of the house itself. Using a dehumidifier can help speed up the process of plaster drying and prevent damage to plaster. The rate of drying is affected by the laws of physics, and it depends on several factors. For example, a higher temperature will make the plaster vaporize moisture more quickly. Conversely, high humidity will slow down the drying process. Another factor that influences the drying time of plaster is the wall material. Brick walls have good absorption, so the plaster will dry faster. A medium-sized dehumidifier will work best for slow drying plaster. Once the plaster is applied, it will typically take three to four days to dry, while a backing plaster can take 4-6 days. Depending on the amount of plaster you've applied, the dry time may be longer or shorter than normal. In humid climates, a dehumidifier can help the plaster dry faster. Another factor that can affect the time it takes to dry plaster is the thickness of the plaster. A thicker plaster will hold more water and take longer to dry. If you're not careful, overly dry air can cause cracks and eczema. Besides being unpleasant for your skin, overly dry air may also cause a large utility bill. The best way to speed up the drying process is to install a dehumidifier that is rated at 60 percent humidity. Leaving a dehumidifier running for more than a day can cause huge cracks in plaster. During the drying process, fresh plaster should be surrounded by ample air circulation and a low background temperature. If you have to rush the plaster drying process, don't forget to open windows. This will allow moisture to escape. Once the plaster is completely dry, you can paint it, but make sure you use a non-vinyl emulsion. It is also important to keep the room warm and dry before applying paint to the surface. PVA glue prevents cracks from forming This mixture enables you to fix a joint in plaster by gluing the edges together. PVA will also prevent sand from penetrating the cracks and filling in the join. Apply the PVA mix rythmically by using a bottle. The glue may drip out of the hole, so use a paper towel to catch it. If the glue is too runny or blows back, you may need to redrill the hole. Before you start plastering, you need to patch test the wall. This is essential for determining the porosity of the wall surface. If it is a low-suction wall, it should be completely dry after a few minutes. Conversely, if the suction is high, it will need multiple coats of PVA. Ensure you have applied PVA glue in the correct quantities for the surface and its thickness. The main chemical compound in PVA glue is polyvinyl acetate. Unlike traditional glues, PVA doesn't produce toxic fumes when dried. In fact, it can be applied to chipboard, MDF, and plywood. It can also be used as a bonding agent and primer for various surfaces. This means that PVA glue is ideal for both interior and exterior projects. While the cracks around windows and doors are considered harmless, large ones at the wall-ceiling joint may cause the ceiling to separate from the wall. In this case, you should seek professional help to get the job done correctly. Plastering is a difficult, time-consuming process that requires two coats of plaster and a base layer of PVA glue. If you can't afford to hire a plasterer, there are some DIY methods to avoid these problems. To make plaster repairs, you can use traditional materials like lime plaster and matching plaster. You can also fill in pockmarks with proprietary interior fillers gauged with whiting. To control suction, diluted PVA can be used. Alternatively, gypsum can be added to the lime plaster mix for the same purpose. In the event that the plastering solution is ineffective, you might need to replace the plaster ceiling and start from scratch.
