Keeney K836-22 Anti-Condensation Toilet Tank Liner Insulation Kit, Prevents Water Damage to Floors, 16-Inch x 48-Inch, White

After reading reviews on the product I was weary about whether or not it would work, but because I needed something to help with the condensation I took a gamble. The delivery was quick and the product was as described on the package. The installation was not hard just had to make sure that after cutting the pieces , they fit before exposing the adhesive. The sides and most of the bottom adhered very well because it was dry, however a couple of spots on the bottom was wet and I had to use glue for it. All in all the product stopped the condensation which is what I needed it to do.

This failed a week after I used it. I took my tank off the toilet. Uninstalled all components and let it dry out before installing the insulation. My toilet tank still was sweating after putting the insulation in, but it was reduced. However, the adhesive failed after a week, and now I'm back to square 1 and down $15. Really poor quality. For it to be effective, it would need to have triple the thickness and a better adhesive. Cost me both money and time for it to be headed to the trash.

I read the other reviews & found using extreme glue no drip Gel Loctite one tube only. Still have 1/3 left. Glue inner by one inch & two inches in between . I did use this on a new one piece toilet in not having any issues with wetness I believe it is best with no bonding concerns. It is still best to cut each side separate as tanks are all different as mine had radius to deal with. This will give you more time to do it correctly with no mess. Yes you will have seams. I also used amazing goop clear for seams for concerns of edges from peeling in the future.

The adhesive doesn’t really work. I found that 2 sided tape works better. 3m makes a good product. The important part is the thin foam that is flexible and water resistant...which is what I was really after.

This stuff does not adhere if water can get behind it. I recommend once you install it you use silicone around the perimeter, or the window and door expanding foam. If you use this to seal all the seams and bottom it works great. (You can always trim it when it dries) This by itself isn’t much use. I had great results using expanding foam on the bottom of the tank and around the bottom edges and seams. No more condensation!

I took everything out including the water. Let it sit to dry and applied the product. Next day I came and the it has started piling off. The toilet was still sweating like nothing has been done to it. 2 days later I noticed the water was running longer and I checked and the product was blocking the stop mechanism because it was piling of even more . By day 5 I decided enough was enough , more that half of the product was not attached and was sort of floating. I decided didn’t want my bathroom and basement to flood and took it out. Waste of time , energy and money. Don’t buy it’s not worth.

Installed by a plumber into a brand new toilet in September of 2019 following all directions. In less then 6 months it started peeling off. Today after less then a year we had to remove it all because it wouldn’t stick. It was preventing the plunger part from sealing causing the water to continuously run because the back couldn’t fill. Every time you flushed you had to reach into the back of the toilet and pull the insulation piece out of the plunger seal so that it could seal and the toilet could fill. Waste of money. The only reason I gave it two stars is that it did reduce the condensation for about 6 months.

To be successful with this kit, you have to dry the inside of the tank, I used a wet/dry vac. Also I cut mine into 4 pieces, wide part of tank front & back and the narrow sides left & right. I purchased a tube of Loctite extreme glue gel from HomeDepot. I put a strip of glue every 2in from bottom to top of inside tank, one section at a time, pulled backing off insulation and press onto wall of tank. I let it sit for 45 min before refilling tank. Worked great! No condensation yet!
