Can I Put Too Much Mud on Drywall? [Best Practice Explained]

Quantity is always important in mudding. To apply the drywall mud, it has a specific recommended quantity.

So now the question is, can I put too much mud on drywall?

The answer is that you should not use too much mud on drywall once because there is a high chance of mud peeling if mud is too thick.

Don’t try it in one coat if your drywall project needs a thick layer. Use multiple coats with the proper method. 

In this article, I will explain the layer of mud and related topics.

How thick should each layer of drywall mud be?

Drywall mud layers divide into 3 layers. Tapping coat, filler coat, and final coat.

If you use paper tape, you have to use a tapping mud coat on drywall joints. This coat should be ¼ inch thick. 

After applying the tape, you have to use a filler coat. This coat thickness should be ⅛ inch. 

After drying the filler coat, you have to apply the final coat. After lite sand, you should use a very thin coat for finishing.

How wide should drywall mud be

As mud layers, there are different widths for applying mud. 

For tapping coat layer, 4-6 inches wide is recommended. 

For filler layer coat, 6-8 inches wide is recommended.

Final coat, 12-14 inches wide mud coat recommended.

However, you can adjust your mud layers for your needs. But the above numbers are recommended for general use. 

How wide should drywall knives be?

To help mudding different wide, you need specific knives called tapping knives.

The tapping coat needs a 4-6 inches wide knife, the filler layer needs a 6-8 inches knife, and the final layer needs a 12-14 inches knife.

This is my recommended tapping knife. You can use it for your project.

What consistency should drywall mud be?

Drywall mud consistency plays a big role in mud projects. If mud is too watery, it can not bond properly, or with less water, the mud can not stick properly.

In other article I explained why drywall mud not stick properly, you can check.

How much thin mud is needed depends on your project type, joint compound type, and weather. Generally, joint compounds need less water like for 1 kg compound, around 1 cup water. 

As well as, we use water in premixed mud. And the water quantity also depends on the project.

I already described premix vs setting compound, you can check.

Always manufacturer mentions how much water is needed for their product. Follow the manufacturer guide.

For example, Sheetrock mentions that Eseysand of 20lb bag needs 5.4 liters of water. Every manufacturer mentions the consistency of mud.

How thick should taping mud be?

Taping mud holds drywall tape. I already described how thick mud should be.

The tapping mud should be ¼ inch thick. And the mud thickness should not be watery, and it should hold tape properly. Follow manufacturer guides, like to use water.

After applying the tape, mud should be dry at a primary level within 5 to 45 minutes for the filler layer.

Conclusion

You should maintain the right thickness, width, lengths, etc to make the drywall finishing project successful. In the article, I touched on the topic.
