Unearth the secrets to safely mounting objects on drywall. From understanding interior wall construction to choosing the right hardware, our comprehensive guide gives you the insight to hang items, big and small, with confidence.
Insight
Understanding the weight capacity of drywall is crucial before mounting or hanging objects on it. Though light items can be supported with a few screws, heavier ones require more secure fixing to avoid damage.
Interior walls typically consist of a 2×4 framework covered by drywall sheets. Inside this framework, insulation, wiring, water lines, and other fixtures are accommodated. To avoid any disruption or potential hazards, it is advisable to use a stud finder to locate the studs within the wall structure.
Owing to the low strength of drywall, secure mounting requires proper hardware and locating wall studs. These are the vertical parts of the wall structure, extending from bottom to top. A stud detector can help you find these. When an object is securely fastened to a stud, drywall can bear up to 100 pounds, compared to only 1.6-2 pounds per square foot if mounted directly.
Ceiling joists are comparable to wall studs in their structural role but can support less weight. Average ceiling joists can bear about 15-20 pounds, possibly increased to 30 pounds with reinforcement.
To safely mount objects, hardware such as anchors is essential. Expansion anchors, ideal for small pictures, can hold between five to 20 pounds. Simple threaded anchors, suitable for heavier items like shelves or TVs, can support 25 to 75 pounds. Straight plastic anchors and winged plastic anchors, both suitable for lighter objects, hold around five to 20 pounds.
Further anchor options include toggle bolts and molly bolts. Plastic toggle bolts can carry up to 20 pounds, while metal versions can support up to 100 pounds if properly mounted to a stud. Molly bolts, which work for both walls and ceilings, can hold 25 to 50 pounds on the wall and up to 10 ounces on the ceiling.
Lastly, the type of fastener used plays a role in drywall’s weight capacity. Picture hangers and nails should be used for items weighing less than 20 pounds. Flat mounted hooks and anchors might support up to 50 pounds, while drywall screws can bear around 20 pounds. To hang up to 100 pounds on drywall, secure the object to wall studs using metal anchors and screws over 3/8-inch long.
