Skim coating is an essential technique professionals and DIY enthusiasts use to achieve a smooth and flawless finish on drywall surfaces. This process involves applying a thin layer of joint compound over the surface to even out imperfections and create a seamless appearance.
However, not all joint compounds are created equal, and choosing the right one for skim coating can be a daunting task. Here, we will delve into the world of joint compounds and discuss the best ones for achieving a perfect skim consecutive coat. We will consider factors such as ease of application, drying time, and overall quality to help you make an informed decision.
Can You Use Joint Compound To Skim Coat?
Skim coating is one of the major treatments for drywalls. You can use joint compounds for skim coating the interior drywall at your house. All you need is to mix the drywall mud or joint compound perfectly and apply it to the wall. When you apply the joint compound on the drywall, it repairs damages and nail holes. Again, it’s an effective hack to remove any blemishes. A thin layer of drywall mud will smoothen the surface for painting and repainting.
There are several reasons for using joint compounds to skim coat. The first reason is the glass-like finish. A knife for drywalls and texture sprayer is generally handy to skim coat. Joint compound comes in different shapes and packages. Powdered, liquid, and premixed are the major ones. Apply it with a knife or sprayer, depending on which classic type of joint compound is suitable.
6 Best Joint Compounds For Skim Coating
A joint compound is an integral part of the finishing process for any coating. Not only does it help to create a smooth finish, but it also plays a crucial role in protecting the underlying surface. One of the primary functions of a joint compound is to reinforce the structural integrity of the surface.
It acts as a barrier, preventing moisture, air, and other potentially damaging elements from penetrating the coating and reaching the substrate. This protective layer helps to minimize the risk of corrosion, water damage, and surface deterioration, thereby prolonging the lifespan of the coating and the surface to which it is applied. Here are six of the best joint compounds for this purpose:

Considerable Factors While Choosing Joint Compound for Skim Coating
Skim coating is convenient and easy when you have the right joint compound in stock. At the same time, it can be difficult and somewhat impossible if you’re messed up with the joint compound. Therefore, picking the joint compound should be perfect. Take a look and match them before buying the product from the list.
Smoothness
Evenly spreading is a must factor for a good quality of joint compound. Smoothness assured from the product is the first thing that you should consider. An unsmooth surface or drywall cannot be painted. When you find drywall mud that spreads fast and quickly, it’ll surely meet your needs. Choose the joint compound that offers even spreading and smoothness.
Texture
Texture is another factor to consider when purchasing a joint compound. There are white, grey, and multicolored textures. Most of the joint compounds offer a white texture. This should match your requirements. Also, you’ll have to ensure that the texture goes with the painting. In many cases, the drywall cannot meet the requirements for the texture. Avoid any multicolored textures if you’re planning to paint afterward.
Drying Duration
Drying duration often hampers the construction or renovation process. If the joint compound takes a lot of time to dry before the next skim coating, it will hamper your time, money, and quality of the skim coating.
Depending on your expected period, choose a particular joint compound that dries as per your expectation. If you are short on time, go for hot, dry mud. These dry fast, and you can apply another coating quickly. Also, drying duration varies according to the material and ingredients used in joint compounds. If premixed joint compound for skim coating is used, this requires less time to dry. However, the price is very high.
Lightweight And Heavyweight
If you’re a beginner in this job and don’t know about skim coating, a lightweight joint compound is a safe choice. It gives better coverage and evenly surfaces. Lightweight compounds also mix easily. Heavyweight, on the other hand, is convenient for professionals. You can purchase them for renovators for large repairing purposes. However, it is recommended only when you need total renovation.
Coverage Rates
It determines the cost and its effectiveness for drywalls in the long run. When you can cover the majority portion of the drywall, it saves money. An evenly, smooth, and large coverage will offer better efficiency and effectiveness to your walls. Such a renovation will also have a direct impact on the cost.
Interior Or Exterior
The last factor is deciding whether to apply the joint compound to recover the interior or exterior walls. If you’re looking for exterior damage control, it should be weatherproof as well as waterproof. Regarding the interior, the glass-like finish will matter the most. Managing the coverage of cracking, nail holes, and blemishes within the approach is essential.
Price
The last but not least factor to consider is price. For personal DIY projects, less pricey ones are preferred. If you’re up for a large repair concept, we suggest getting an expensive one. This will improve the outcome several times. Expensive materials often have better features, improved performance, and enhanced aesthetics.
