Liquid adhesives can sometimes hold a loose drywall anchor temporarily but they are rarely a reliable long term fix.

Liquid adhesives lack compressive strength, which means they do not resist the squeezing forces anchors experience inside drywall, so use them only as part of a repair strategy rather than a standalone solution. For small, light items use a high quality construction adhesive or polyurethane glue combined with a high density filler such as setting-type joint compound or epoxy putty to fill the hole, let the filler cure fully, then redrill a proper pilot hole for a new anchor. When using epoxy putty press it firmly into the void and mold it around the original anchor area, allow the full cure time indicated by the manufacturer, then trim and sand flush before installing a new anchor; this creates a mechanical mass that the anchor can bite into. For medium loads consider switching to a threaded anchor sized for thicker drywall or to a toggle or molly style anchor that spreads load behind the board rather than relying on surface compression. Avoid simply injecting thin craft glue or super glue into the cavity because those products cure brittle and will fail under shear or repeated loading. Always check the weight rating of the anchor system relative to the expected load and if the load is significant consider mounting into a stud or using a bracket that transfers force to multiple fasteners.

Common mistakes include assuming any glue will restore anchor strength, relying on the anchor that originally failed, and not addressing the surrounding drywall damage. People often inject ordinary glue into the hole and expect long term holding power, but ordinary glue has poor compressive and shear capacity and will crumble, so use a structural filler or switch anchor types instead. Reusing the original loose anchor is tempting, but once the drywall fiber is crushed the anchor cannot regain purchase, so remove it, repair the hole with a dense compound or epoxy, and install a new appropriately sized anchor. Ignoring the damaged drywall around the hole lets the repaired anchor pull through under load, so create a solid repair by removing loose material, filling with a setting compound, and reinforcing with a backing plate or larger anchor when needed.
