For painting drywall, many homeowners and DIY enthusiasts may wonder if it is possible to skip the mudding process altogether and paint unfinished drywall. Adding a specialized topping mud or applying joint compound for sealed and primed drywall panels, is done to create a smooth and even surface for painting.
However, it can be time-consuming to hide imperfect drywall seams, which may lead some to skip them altogether. While it is technically possible to paint drywall with no mud & drywall tape, it is there for a good reason, so it isn’t recommended to paint drywall without mudding.
Without mudding, the seams between drywall panels will remain visible and may even be accentuated by the paint. The lack of joint compound can make the surface more vulnerable to damage and cracking. Some techniques and products can minimize the need for mudding.
Mesh tape, for example, can reinforce the seams between drywall panels and create a smoother surface for painting. Specialized topping mud can create a smooth finish without multiple coats of joint compound. In our guide, you can learn more about do you mud the entire drywall before painting. By the end, you’ll better understand mudding walls and why you must mud to get the best finish. (Learn How To Hang Dry Erase Board)
Do You Have To Mud Drywall Before Painting?
It is generally recommended to mud drywall before adding new paint. Mudding, or applying joint compound to the seams between drywall panels, helps create a smooth and even surface for painting.
Without mudding, the seams between drywall panels will remain visible and may be accentuated by the paint. The lack of joint compound can make smooth joints on the surface more vulnerable to damage and cracking over time.
- For example, drywall properly taped with mesh tape reinforces the seams and creates a smoother surface for painting.
- Specialized topping muds can also create a smooth finish without several coats of joint compound.
- Even if the drywall has been previously mudded with several coats, it may require additional touch-ups before painting.
- This can include sanding down rough patches or applying additional joint compound to fill in gaps or imperfections.
Why is Drywall Mud Necessary?
Drywall mud, or joint compound, is critical in finishing drywall installations. It fills gaps and cover seams where drywall meet, creating a smooth surface ready for painting or wallpapering.
Here are some reasons why drywall mud is necessary:
- Stopping moisture: Drywall mud helps to seal and protect the drywall from moisture, preventing mold and mildew growth that could lead to structural damage or health problems.
- Fire hazards: Drywall mud also provides fire resistance to drywall installations. When properly applied, it can help slow the spread of flames and smoke in the event of a fire.
- Pests: Drywall mud can also help to prevent pests, such as rodents and insects, from entering through gaps and seams in the drywall.
- Building code: In many jurisdictions, building code requires drywall mud to finish drywall installations in homes and attached garages. This ensures that the drywall meets fire safety and other building standards.
Poorly finished drywall could also be aesthetically unpleasing. It is crucial to use the correct type of mud and apply it correctly to ensure the durability, safety, and aesthetic appeal of the drywall installation.
Steps To Properly Mud and Paint Drywall
Properly mudding and painting drywall is crucial for achieving a smooth and flawless finish. Here are some steps you can follow:
1. Mud and Tape Drywall:
- Begin by applying mesh drywall tape over the seams of the drywall sheets.
- Use an all-purpose joint compound to cover the tape and fill any gaps or cracks in the drywall.
- Apply your second coat of joint compound, then let it dry.
- Sand the seams with a sanding block or pole sander to create a smooth surface.
- Apply a third coat of joint compound, feathering the edges to blend with the surrounding drywall.
- Let the joint compound dry completely before proceeding.
2. Sand After Final Coat:
- After the final coat of the joint compound is dry, use fine-grit sandpaper to sand the surface smoothly.
- Wipe the drywall surface with a damp cloth to remove any dust.
3. Prime Drywall:
- Apply a high-quality primer to the drywall surface to seal the joint compound and provide a base for the paint. Also, it delivers a blank canvas for your new paint.
- Allow the proper primer to dry completely before painting.
4. Paint Your Walls:
- Choose your desired paint color and apply it in even strokes with a roller or paintbrush.
- Apply multiple coats as necessary, allowing each coat to dry completely before applying the next.
- These steps ensure your drywall surface is smooth and properly prepared for painting.
How many coats of paint do you need for bare drywall?
When painting bare drywall, applying at least two coats of paint is generally recommended.
The first coat serves as a primer, helping the paint adhere to the surface and providing a consistent base color. The second coat is applied for coverage and to achieve the desired final paint color. (Read Drywall Screw Size Chart)
Before applying any paint, properly preparing the drywall surface is essential.
This can include sanding down any rough spots or imperfections, filling in gaps or cracks with joint compounds, and ensuring the surface is clean and free of dust or debris.
- Priming the surface with a high-quality primer can also help ensure the final paint adheres properly and provides even coverage.
- When applying paint, it’s essential to use a high-quality paintbrush or roller to ensure an even application.
- Applying too much pressure or using a low-quality tool can result in uneven coverage or visible brush marks.
- In some cases, additional coats of paint may be necessary depending on the desired finish or color and the quality of the paint being used.
- However, two coats are typically sufficient for most standard applications, even if you have correctly sealed and primed drywall.
What Happens If You Don’t Mud & Tape Drywall Before Painting?
If you don’t mud and tape drywall before painting, the surface may look uneven, with visible seams and imperfections.
Mud, or joint compound, fills the gaps between drywall panels and creates a smooth, seamless surface. These gaps will be visible without mud, and the surface will not look smooth. Taping drywall together is also important because it helps reinforce the joints between drywall panels and prevent them from cracking or separating over time.
If you attempt to paint over unmuddied and untaped drywall, the paint may not adhere properly, resulting in an uneven and unprofessional finish. The paint will highlight imperfections or gaps, making them even more noticeable when painting unfinished drywall.
To achieve a smooth and professional-looking finish, it’s essential to properly mud drywall joints before painting. Taping drywall together involves applying drywall tape over all the joints and embedding it in the joint compound, followed by another layer of joint compound and sanding.

Creative Ways To Hide Drywall Seams Other Than Tape & Mud
If you’re looking for creative ways to hide unfinished drywall seams other than tape and mud, there are several options to consider. More flat or matte paint may also be effective in minimizing the appearance of seams, although it may not be as effective as textured finishes.
Note: never use high gloss paint in your finishing drywall painting process. Unlike flat paint, high gloss reflects lights and shows imperfections, such as where drywall sheets meet each other or the paper tape, even on a primed wall. Another option is to install trim or molding, such as quarter round or chair rail, to hide drywall seams.
While tape and mud are the traditional methods for hiding drywall seams, many creative alternatives exist. Whether you choose to do wall paint, use texture, quarter-round trim, tile, or lighting, there are endless possibilities for creating a unique and attractive wall surface besides painting plain drywall paper or hiding drywall seams.
Can You Paint Drywall Directly?
Painting drywall directly with no preparation can lead to various problems. It is not recommended to skip essential steps like mudding drywall joints, sealing drywall seams, or priming the drywall. Mudding drywall joints is crucial for the surface to be smooth on sealed drywall.
In addition to sealing and priming, adding drywall paper before painting can provide extra protection for the drywall. Suppose you paint the entire wall and don’t adequately cover your vertical or horizontal seam. In that case, you may encounter problems such as peeling paint, uneven finish, and an unattractive appearance on your painted space.
Peeling paint can occur when the paint does not adhere properly to the drywall surface, which is more likely to happen if the drywall is not properly sealed and primed. (Learn How Many Coats Of Primer On New Drywall)
