OTR microwave mounting
SeanG

Hello. I recently purchased a home built in 1925 and am beginning to make some upgrades. What I'm doing now is installing an over the range microwave in the kitchen. My house is block construction and the wall that I need to install the microwave on goes to the exterior of the house (therefor no studs to mount the bracket on, only what appears to be hollow block directly underneath the plaster). My question is if whether or not it is safe to install the microwave there? Will I be ok if I use a masonry bit and some long blue tapcons? Is there a better type of anchor? Also the block seems to be very brittle (I had no issue drilling through it with a small cobalt bit and crappy drill while trying to find a stud.) Thanks in advance for any advice!

Just use molly bolts and remember to blow the dust out of the holes you drill.

Isn't this covered in the installation manual ?

Thanks for the tip. Actually the manual doesn't have anything about mounting to block. One of the location requirements states "Minimum one 2x4 wood wall stud and minimum 3/8" thickness drywall or plaster/lath".

You could glue a piece of plywood to the wall, set with molly's. PL Premium is far better than liquid nails
