If you are considering skim-coating as a wall treatment, you need to understand the basics of skim coating and its application.Īpplying a layer of drywall joint compound will give your walls a uniform, smooth finish that mimics stucco or popcorn textures. The loose sections of plaster can break free from the lath keys behind and will ultimately crack. While skim-coating can solve most cracks in plaster, it can’t solve the underlying problem. The process of applying drywall joint compound over a textured plaster wall is known as skim coating. Some types of joint compound may require more than one coat. A trowel can be used to apply joint compound and press it into crevices and cracks. The main difference between applying joint compound and skimming is that the latter requires no abrasive tools. The process is similar to that of applying joint tape. If you can’t find a brush or roller, you can use a spatula to apply the compound.Īfter sanding and priming, you can apply drywall joint compound over the surface of the textured plaster. The right tool for the job is a 6” taping knife. Beginners can make it easier to spread by mixing ten percent water. The powdered variety is finer than its liquid counterpart.

The powder version takes longer to dry, so beginners can practice a bit before they start sanding. Therefore, you should lightly sand the walls before applying the final coats of drywall compound.ĭrywall joint compound comes in buckets or boxes. Furthermore, if the walls are painted with high gloss paint, the compound may not be held well by it. In such cases, you may need to mix it with more drywall compound to stiffen it up. If it is too thin, it will not hold properly on the wall. The consistency of drywall joint compound can vary widely. The use of joint compound is a great way to refresh outdated walls. On the other hand, plaster is labor intensive and requires more sanding to achieve a seamless finish. However, it is more susceptible to cracking once it dries. It can be used on walls with gaps of less than one eighth inch. Compared to plaster, joint compound is easier to sand. Ensure the area is clean and dry before applying joint compound.ĭrywall joint compound is the material used to smooth textured plaster walls. You can also use paper tape to patch large areas of damage. Sand the wall after applying the joint compound to avoid unevenness. Avoid gluing adhesives to the joint compound, as they make sanding more difficult. A clean wall will adhere better to joint compound. Other methods for smoothing textured plaster walls include using a squeegee or a notched trowel.īefore applying joint compound, you should clean the wall thoroughly and make sure it is free from dust or grease. You may apply additional joint compound if needed. Then, dip a sponge in the joint compound and press it against the wall repeatedly to create a texture on the whole wall surface.

Using a trowel or a wide compound knife, apply a thin layer of joint compound to the wall. The application process for joint compound is comparatively simple.
