CS-4300 Mirror Adhesive, Low Odor, VOC Compliant, 10.1oz Cartridge

Yeah, so the mirrors in my house decided to start falling off the walls after about 22 years... that was entertaining. "What's the strange crashing sound?" The first time it happened, I thought someone was breaking into the house. Crazy. Near as I can figure, the idiot sticks who build this house didn't know what they were doing. I think they might have just used silicone or liquid nails or something in a half-baked attempt to install the mirrors. I mean it did last 20+ years, but definitely not the right product. Enter CS-4300. I used this product to put the replacement mirrors back up on the wall and all I can say is "wow". Really easy to apply to the walls and it grabs the mirrors and hangs onto them for dear life. Before using this product, I thought maybe I might have to stand there holding the mirror up or secure it during the drying process with tape or something. Nope.... As soon as the mirror back touches this stuff, it's golden. I just did some zig-zag patterns on the wall and some heavy straight lines around the outside edges of where the mirror would lay up to the wall and boy oh boy, did the mirror stick fast. In fact, so fast that you don't have a lot of repositioning time I don't think. Yeah, you can kind slide the mirror over a tiny bit (like 1/16th or so) right after it get up on the wall and before you push the mirror against the surface, but I would say if you suddenly decided you needed to take the mirror back off the wall, I don't know if that would be possible or not. This CS-4300 really grabs on. Once my mirror was up, I also ran a bead along the very top edge of the mirror to provide even more grabbing on power. I don't think these new mirror will be coming off the walls anytime soon. So all in all super pleased. My mirrors were around 30x50" and I used two tubes per mirror. One tube will also get it, but I wanted to have extra adhesive on the wall for each mirror, because let me tell you, cleaning up a shatter mirror that has magically decided to liberate itself from the wall is not a lot of fun. 5 stars on this stuff for sure. If you are putting up mirrors, this is the product you've been looking for. Put the mirror up, push it onto the wall - done.

was easy to apply to the wall and I did a lot of research. I believe it will last a long time. Served my purpose perfectly.

I used it to hang (4) 16"x58" 1/8" mirrors on 4 doors. They weighed about 10 lbs. each. I sanded them with 220 sandpaper to ensure good adhesion (They were painted with semi-gloss paint) and took them down. Used ONLY this glue-NO MECHANICAL FASTENERS!! I used one tube for all 4 mirrors! Three vertical lines of this caulk evenly spaced apart from top to bottom. After 48 hours put the doors back up, and the mirrors are stuck really nicely! It's been a week and those mirrors are still up there as strong as ever!. We didn't want to wait longer then that because we wanted our bedroom doors back up..... HIGHLY recommend!

Supposedly the best thing out there and its certainly working well in my case. Glued a 1/4" thick ~30"x48" mirror with five ~3"x18" contact patches and its holding strong. Its exposed to 60-90deg swings with humidity at times and I've noticed no issues. This is a lot of adhesive though, so it seems excessive if you've only got one mirror to hang. Wish you could buy it in a smaller size.

Works! Glued 4 giant 1/3inch thick 8x4ft mirror panels to create a mirrored wall in my living room against prepped drywall and 3 years on not a single issue. I followed all instructions and applied liberally in a crosshatch fashion directly to the back of the mirrors. Took 2 tubes for a 16x8 foot area. These were, guessing by lifting it, around 150 pounds each easily, probably more. No corrosion on the back, and all 4 haven't misaligned the image at all. Even a fraction of an inch would ruin it. Still feel completely glued all around. If you're considering having a large mirror installed, you can save several hundred dollars and do it yourself. The guy at the glass store said, between me and him, that just about any construction adhesive will work, but to be safe I picked this slightly more expensive product. Very satisfied. What more can I say.

Worked very well. Good value for your money.

This product let go of our mirror 45 minutes after it was on the wall. We held it beforehand to apply pressure and it didn't slide at all when we let go. Then it came down. Thankfully it didn't shatter everywhere. Best of luck to everyone else.

Excellent adhesion for both wood and PVC trim to the mirrors. Used on large and heavy mirrors (4' x 6')

I used this product to permanently glue a mirror in my Daughters Salon Studio. It worked immediately and feel confident it will not fall. Thank you.

Did the job.

It actually worked really well. I had a really large mirror that was thick and heavy and it held nicely to my drywall.

I was uncertain how this product would perform given some of the mixed reviews on Amazon, and elsewhere online. I have to give credit when it’s due, this stuff worked great. I glued a 66”x24” mirror to a white oak frame, followed the instructions to a t, and it did the job. Next to no smell, and quick setup. Left it overnight and the bond seems solid. Highly recommend. Only reason it didn’t get a 5 was due to the lack of an applicator I had to go out and buy before using, would be nice if that was included

Extremely thick, very hard to get out of the tube. Ended up bending the caulk gun making it unusable part way through so had to use clamps to try and squeeze out the rest. Seems to be holding but wasn’t able to get more than 1/3rd out of the tube even after cutting the nozzle wider several times. Must have been old or dried out product.
