9 Factors to Consider for Choosing the Best Drywall Mud for Skim Coat

excess mud

It is important to consider several key factors when selecting a drywall compound for your skim coating project. Because you want to get a perfect finish, you need to make sure that the product is of good quality and will give you excellent results.

Knowing some of these factors will assist you in selecting the right product for your project. So let’s take a look at the factors you should consider when choosing the best joint compound for skim coating.

1. Adhesion

When you apply the compound to your walls, you must ensure that it will adhere well and not slide off.

The adhesive quality of a joint compound is extremely important when it comes to skim coating, as you want the compound to stay in place while you are working on the project.

Upon drying, the compound should remain firmly attached to the surface. As you buy a joint compound online, there is no way to test the quality. So how do you know if it has good adhesion? 

The best thing to do is check the reviews from customers who have used the product. You can also find information concerning the adhesion quality in the product description.

A fiber-reinforced compound provides better adhesion and durability. It is also advisable to look for joint compounds that comply with industrial standards, such as ASTM C475.

2. Crack Resistance

Any joint compound needs to have excellent crack resistance. You should choose a product that is strong enough to prevent the walls from developing cracks, regardless of whether you use it over metal fasteners.

You need to carefully read the product description to make sure that the manufacturer claims that it has excellent crack resistance.

For real-world proof, you can check customer reviews to see if other people have succeeded with this type of product.

3. Drying Time

It is particularly crucial if you want to complete your project quickly. You need a joint compound that dries fast to move on to the next step of the skim coating process. You can find this information in the product description and also in customer reviews.

It is also important to note that some joint compounds require priming before using them, which will add time to your project. So choose a product that does not require priming. It will save you both time and money.

4. Interior and Exterior Use

It is important to pay attention to the type of joint compound you are buying. Some joint compounds are designed for interior use only, while others can be used both indoors and outdoors.

You will find it beneficial to choose a joint compound that can be used in both interior and exterior applications, as this will save you money in the long run.

This type of product is more versatile, which makes it suitable for most projects. The product description contains this information, so read it carefully before purchasing.

5. Ease of Sanding

taping compound

Once the joint compound has dried, you will need to sand it to get a perfect finish. You must choose a product that is easy to sand and produces minimal dust. This will enable you to save time and effort when sanding your drywall joints and other surfaces.

You can obtain this information from the product description, or you can look at customer reviews to learn how others have experienced the product. In this way, you will be able to get a better sense of how easy it is to sand joint compounds.

6. Speared Ability

The product you choose should be able to spread easily across your walls. This will help you achieve a perfect finish and prevent uneven patches from appearing on the surface.

That’s why a lightweight joint compound is popular for skim coating. Such a product can be spread more easily, resulting in a uniform finish. After that, you can sand the surface to get an even easier finish.

7. Shrinkage

You need to check the shrinkage rate of the joint compound. It should be low enough so that it won’t cause cracking or shrinking as it dries. This is especially important if you are using a lightweight joint compound for skim coating.

Low-shrinkage products are preferable because they will provide a better finish and be more durable over time. When you read the product description, look for “low shrinkage” to indicate that it is suitable for skim coating.

8. Quantity

For your project, you will need a certain quantity of joint compound. You should buy enough to cover the entire surface without replenishing supplies in the middle of your work.

Most manufacturers provide information about how many square feet their product can cover so that you can estimate the amount you will require and ensure you have enough on hand. In the product container, image and description, you can find information regarding the quantity of the item.

Depending on the nature of your project, some quality joint compounds may not come in large quantities, but you can buy more than one container to ensure that you have enough.

9. Included Accessories

You should pay attention to the accessories included in the product. Some joint compounds come with special tools that will make the application easier and produce better results.

For example, you may get a putty knife, sanding sponge, tape, or other accessories to help you complete your project. This is important to note as it can save you time and money if you don’t have to buy these items separately.

How Many Coats of Drywall Compound Should I Use for Skim Coating?

topping compound

A general rule of thumb for skim coating is to apply two coats of drywall compound. This will provide a smooth surface and minimize the amount of sanding required between layers.

But if your walls are particularly uneven, you may need to apply as many as five coats to achieve a smooth finish. The type and quality of drywall mud also affect the number of coats required.

For best results, apply four or five thin layers to the surface. In this way, less sanding will be necessary, and the final result will look more professional.

Can You Apply Drywall Compound Over Paint When Skim Coating?

You can certainly apply drywall compound over paint, but there are a few things you need to do first. Most wall paint contains chemicals that impart a glossy appearance, making it difficult for the mud to adhere properly.

So before you start, you’ll need to rub away the existing paint using 280-grit sandpaper. It will create a surface that is a rough and textured wall and will facilitate the adhesion of the mud. After sanding, sweep away the particles, and then you can apply the drywall compound.

How Long Does a Skim Coat of Joint Compound Take to Dry?

skim coat wall

The skim coat joint compound’s drying time varies depending on the temperature, humidity, and product type.

In general, in 70° Fahrenheit (21° Celsius) temperatures and 70% humidity, it can take about 24 hours for the joint compound to dry.

There may be some products with quick-drying formulas that will be set in less than an hour. The drying process for some products may take up to 12 hours.

Always remember that the drying time can vary significantly depending on the temperature and humidity.

Get Smooth, Strong, and Flawless Wall Surfaces with Quality Drywall Compound

It is now evident why you need to use a quality joint compound when skim coating. When selecting the right product, always look for lightweight compounds with a low shrinkage rate.

Be sure to consider the quantity and how many coats are necessary to get the job done. Remember that even if you plan on applying drywall compound over paint, it is essential to sand the surface before application.
