Yes, you absolutely can use tape with hot mud, particularly mesh tape.
When working with drywall joints that require a rapid-setting compound like hot mud (also known as setting-type joint compound), incorporating tape is a standard practice for reinforcement and stability.
Using Mesh Tape with Hot Mud
According to experts, it is important to use hot mud specifically with mesh tape. Unlike paper tape which requires a base coat of standard joint compound before embedding, mesh tape is often self-adhesive and designed to be used directly with hot mud.
The process involves applying the mesh tape over the joint first. Then, you apply the hot mud, making sure to push the hot mud through the mesh tape into the joint behind it. This technique is crucial because you want a solid bond between the mesh tape, the mud, and the underlying joint itself. This ensures the joint is properly filled and reinforced, preventing cracks later on.
Key Points from the Reference:
- It's essential to push hot mud through the mesh tape.
- Pushing mud through the tape ensures it reaches the joint behind it.
- The goal is a solid bond involving the mesh tape, the hot mud, and the joint.
- You should use hot mud specifically with mesh tape.
Practical Application
Using mesh tape and hot mud together offers several advantages, especially for repairs or when speed is needed:
- Speed: Hot mud sets quickly, allowing multiple coats or subsequent steps within a short timeframe.
- Strength: The chemical setting process of hot mud, combined with the mesh tape reinforcement, creates a very strong joint.
- Versatility: Suitable for a variety of drywall repair and finishing tasks.
Here are some practical tips for success:
- Apply Mesh Tape First: Ensure the mesh tape is centered over the joint and pressed firmly into place.
- Mix Hot Mud Correctly: Follow the manufacturer's instructions for mixing hot mud to the right consistency. It should be workable but not too thin.
- Apply with Pressure: When applying the hot mud over the taped joint, use enough pressure with your joint knife to force the mud through the mesh openings and into the void of the joint.
- Wipe Smooth: After embedding the tape and filling the joint, carefully wipe the surface smooth, removing excess mud while leaving enough to cover the tape completely.
Using mesh tape with hot mud is a recommended and effective method for reinforcing drywall joints and repairs, creating a strong, durable finish.
