This video is a detailed DIY tutorial on mudding and taping drywall, led by the creator of RR Buildings, who shares his self-taught techniques from years of experience. The process begins with essential prep work, including ensuring all drywall screws are properly recessed, trimming loose paper from joints, and thoroughly vacuuming dust. The creator demonstrates taping various types of joints using different materials: "Straight Flex" tape for sharp inside corners, paper-faced metal beads for durable outside corners, paper tape for standard tapered joints, and mesh tape for challenging butt joints. A significant portion of the video showcases the use of professional-grade Level 5 mudding boxes to efficiently apply consistent coats of mud to flat surfaces. The tutorial covers the progression from a glue-heavy all-purpose compound for the initial taping to lighter, easier-to-sand topping compounds for subsequent coats. The video concludes with the walls fully taped and coated, ready for the final sanding and painting stages.
Drywall Mudding Tips and Tricks for the DIYer
0:28 Pre-Mudding Prep is Crucial: Before applying any mud, ensure all screws are slightly recessed below the drywall surface. Trim any loose or frayed paper from joints, especially butt joints, to ensure the tape lays flat.
3:25 Shaping Uneven Corners: Use a rasp to smooth out any drywall sheets that stick out past each other on outside corners, creating a flush surface for the corner bead.
4:10 Vacuum Thoroughly: To prevent debris from contaminating your mud, vacuum all dust from electrical boxes, joints, and the floor before you begin taping.
7:02 Inside Corners with Straight Flex Tape: The creator recommends "Straight Flex" tape for inside corners, as its rigid design helps create a perfect, straight line with less mud required for finishing.
14:13 Installing Outside Corner Bead: He demonstrates using paper-faced metal corner bead, which is embedded in mud. He advises being careful not to push the bead in too far, as you want a slight gap to fill with mud for a strong, sharp corner.
18:40 Taping Different Joint Types: The video differentiates between easy tapered joints (factory recessed edges) and more difficult butt joints (where two cut ends meet). He uses paper tape for tapered joints and fiber mesh tape for butt joints (26:02), as the mesh is thinner and less prone to bubbling.
22:28 Side Project - Waterproofing Test: The project is briefly paused to test a previous foundation crack repair. The creator soaks the ground outside with a hose for 45 minutes to simulate heavy rain and confirms the basement remains dry before covering the wall.
29:04 Switching Mud for Finishing Coats: For embedding tape, an all-purpose "green lid" mud with more glue is used. For subsequent finishing coats, he switches to a lighter weight topping compound, which is easier to work with and sands more smoothly.
35:07 Using Professional Tools for Efficiency: The creator uses Level 5 mudding boxes (10-inch and 12-inch) to apply mud to all flat and butt joints. These tools lay down a perfectly even and feathered coat of mud far faster than can be done by hand.
39:25 Corner Finishing Strategy: To achieve a sharp inside corner, he applies mud to one side of all corners, lets it dry completely, and then comes back to do the opposite side.
43:04 Don't Overwork the Final Coat: On the final pass, he advises not to obsess over minor lines or ridges left by the knife. These small imperfections are easily removed during sanding, and trying to fix them while wet often makes it worse.
48:50 Next Steps: With all mudding complete, the next phase of the project will be sanding, priming, and painting the new walls.
Summary of YouTube Comments
The comments section reflects a highly engaged community of DIYers and professionals offering their own advice and sharing experiences.
Alternative Techniques and Tips: Many commenters shared their preferred methods. Popular suggestions include sliding a wide knife across screws to listen for a "tink" to find proud ones, using a damp sponge for sanding to eliminate dust, and using a traditional hawk and trowel setup.
Regional Finishing Differences: Viewers from other regions pointed out different standard practices. A commenter from the UK noted that full plastering of walls is common there, while another from the US Northeast mentioned the use of blue board and a hard plaster skim coat as an alternative to drywall mudding.
Constructive Feedback: Some users offered specific critiques, such as questioning if the screw pattern met local building codes, advising against ultra-light mud for being too sandy, and suggesting he was flexing his knife too much on the final coats.
General Sentiment and Appreciation: The overwhelming sentiment was positive. Many viewers expressed gratitude for the detailed tutorial, sharing that they were about to tackle their own drywall projects. Others commiserated on the difficulty of the task, calling it an "art form" or a "form of torture," reinforcing the video's value for those learning the trade.
