What Joint Compound to Use in Shower: A Comprehensive Guide
Hey there, readers!
Welcome to our in-depth guide on selecting the perfect joint compound for your shower. This article will dive into the different types of joint compounds, their advantages and disadvantages, and specific recommendations for shower applications. So, put on your contractor hat and let’s get started!
Types of Joint Compounds
Regular Joint Compound
Regular joint compound is a versatile option suitable for most interior drywall applications. It’s relatively inexpensive and offers a smooth, durable finish. However, due to its moisture-absorbing nature, it’s not ideal for showers.
Setting-Type Joint Compound
Setting-type joint compound sets faster than regular joint compound, allowing for quick repairs. However, it can be more difficult to work with and may crack if not applied properly. Again, its moisture susceptibility makes it a poor choice for showers.
Waterproof Joint Compound
Waterproof joint compound is specially formulated to resist moisture, making it perfect for showers. It contains polymers that create a water-repellent barrier. However, it’s typically more expensive than regular joint compound.
Considerations for Shower Joint Compound
Flexibility
Joint compound in showers is subjected to temperature fluctuations and moisture movement. Choose a flexible compound to accommodate these changes and minimize cracking.
Mold Resistance
Bathrooms are prone to moisture buildup, creating an ideal environment for mold growth. Opt for a joint compound that contains mold-resistant additives to prevent unsightly stains.
Coverage
Calculate the square footage of your shower walls and ceiling to determine the amount of joint compound needed. Consider the thickness of the compound and the number of coats required for full coverage.
Recommended Joint Compounds for Showers
- Custom Building Products RedGard Waterproof Cement
- Ardex WA Waterproof Joint Compound

Joint Compound Application in Showers
- Prepare the Surface: Clean drywall with a damp sponge to remove dust. Apply a coat of primer specifically designed for waterproof drywall.
- Apply Joint Compound: Using a putty knife, apply a thin layer of joint compound to the joints and corners. Smooth out with a wet sponge.
- Tape and Joint: Reinforce the joints with fiberglass mesh tape and apply another layer of joint compound.
- Sand and Prime: Once the compound is dry, sand it smooth and apply a second coat of primer.
Summary Table
| Joint Compound Type | Waterproof | Mold Resistant | Flexibility | Cost |
|---|---|---|---|---|
| Regular | No | No | Moderate | Low |
| Setting-Type | No | No | Low | Moderate |
| Waterproof | Yes | Yes | Good | High |
Conclusion
Choosing the right joint compound for your shower is crucial to prevent moisture damage and ensure a durable finish. By considering factors like flexibility, mold resistance, and application requirements, you can select the perfect compound for your bathroom.
