I have a lot of kitchens to install on walls with double drywall over metal studs. My Franklin Sensors stud finder is great for single drywall but is failing on double, I have been having to search for them with a screw and things aren’t really OC. What strategies are recommended for finding studs in such a situation?

  • How would one of those old school cheapo stud finders work? The type that uses a magnet to sense the nails, but in this case, it's the studs themselves – Ack Sep 1 '20 at 23:00
  • Is adhesive used to bond the two layers of drywall? Are the seams staggered? – Jim Stewart Sep 2 '20 at 18:04
  • I see from the OP's comment above that these are "heavy gauge" studs. So the OP's choice of self drilling #12 screws into the studs to secure cabinets sounds much better to me than at first. In fact I can see it being absolutely first rate,, but I still think that for installing "many kitchens" there ought to be a professional evaluation, but the OP may have done that without saying so. – Jim Stewart Sep 3 '20 at 10:59

    Does your stud finder have a "deep scan" or "metal stud" mode? Some modern ones do and may find those studs without issue. It might just be a matter of the right device. – isherwood Sep 3 '20 at 14:48

The same way we find studs for single drywall.

Magnetic stud finder

enter image description here

Your drywall has to be screwed in properly. You will have vertical columns of screws. When the magnet hits something, go up or down a little, if it hits a vertical column - there is your stud. Since it is double drywall there would definitely not be skipping of studs so you should be able to mark everything in kitchen in a few minutes.

  • Yeah, I think the magnet might be a rather good bet here actually – ThreePhaseEel Sep 3 '20 at 0:56
  • That stud finder represents the best $7 I've ever spent! So much easier to use than the electronic ones, and it works great on my plaster walls as well. – PhilippNagel Sep 3 '20 at 13:27
  • @PhilippNagel The only issue I have had - and I have bought 5-6 of these for my teams... is the pointer at the bottom of the picture is a hard plastic. It is solid. But when it drops from 4 feet onto concrete it cracks. But this tool is a time life saver. Side note - I have also used it to find surveying stakes outside in yards. The magnet is so strong that if I am within 6 inches, using a sweeping motion I will notice a tug. – DMoore Sep 3 '20 at 16:21
  • I’ll give it a shot thanks :) – Jacko Sep 4 '20 at 17:24

Worth investigating: NEW Walabot DIY Stud Finder In-Wall Imager.

You could consider avoiding the metal studs. Use proper drywall anchors for #12 screws. Drywall is very strong if the clamping force of a fastener can be spread out.

If you are installing many kitchens, I would think you should get a professional expert to recommend the fastening system for hanging cabinets on 1 inch thick drywall on "heavy gauge" steel studs.
