Let each section dry completely before moving on to another area. This will help prevent cracking once everything has dried completely overnight. Make sure not to leave behind any gaps as this could lead to uneven coverage when painting later on. Start at one corner of the room and spread outwards in small sections until you reach all four corners. Now it’s time to apply your joint compound onto your prepared wall surface using either a trowel or putty knife. Once this is done, use sandpaper to lightly scuff up any glossy surfaces so that they have more texture for better adhesion of the joint compound. If there are any cracks in the wall surface, these should be filled with spackling paste before proceeding with the skim coating process. This will help ensure that the skim coat adheres properly and provides a uniform finish. Preparation of the Wall Surfaceīefore beginning any work on your plaster walls, it’s important to ensure that they are clean and free from dirt or debris. With the right preparation and materials, you can achieve excellent results with minimal effort. ![]() The process involves preparing the wall surface and applying a thin layer of joint compound or skim coat to create an even, seamless look. Skim coating over painted plaster walls is a great way to give your interior walls a smooth, professional finish. Can You Skim Coat Over Painted Plaster Walls? ![]() Key Takeaway: Skim coating is an effective way to give walls a smooth finish, and when done correctly can create a stunning effect. Additionally, if there are any cracks, dents, holes, or other imperfections on the wall, they will all be covered up after the skim coat has dried, giving you a clean slate for your next project such as painting or texturing your walls again with wallpaper.įinally, because this process only requires one thin layer, it can save time compared to traditional methods like drywall taping and mudding which require multiple layers before being ready for paint application. One major benefit of skim coating is that it creates an even surface on the wall which allows paint colors to look more uniform when applied over it. It’s important to note that skim coating should not be confused with drywall taping and mudding which requires multiple layers of joint compound applied thicker than what would be used for skim coating. The purpose is to create an even surface before repainting the wall or adding a new texture. Good luck.Skim coating involves the application of a thin layer of joint compound or plaster over existing walls that have been painted or textured with wallpaper. It only takes 20mins for most joint compounds to set, so the lengthy process time comes in if you don't do it right the first time and you end up sanding your life away. This is a very easy process to learn if you are willing. ![]() I'm not sure why you would get a friend who has no experience in this to do this for you. In regards to the pro giving bad advice, you have to take responsibility to verify that info regardless. I would just use a putty knife to scrap off the poorly adhered compound, if you choose to tackle it on your own. Make sure you don't wait too long though or you might start seeing some cracks in your wall that you will have to fill. Shellac would probably the best for a top coat because it's super hide and seals. You have to seal again after, either with Gardz or Shellac. ![]() It's also possible that he was confused about you were asking or covering. Maybe he meant you don't have to prime, but you do have to seal. I've used both as a base for skim coating and prefer Gardz, since it is easy to apply with a brush, clear, and doesn't stink like shellac. You have to seal the wall for the joint compound to stick. ![]()
