    Pools return leaks

    Posted by Jennifer Roberts on 21st Mar 2022

    We were dealing with a really stressful leak situation on our newly remodeled pool. The contractor was no help so I did some googling… found Mr. Sticky’s glue and decided to call the customer service number. Boy am I glad I did, Mr Sticky himself brainstormed with me, told me how to work with the glue. And ultimately saved us having to drain our pool to fix the leaks. Amazing glue & customer service, buying more to do our hot tub too just as a preventative

    Plastic to Porcelain

    I glued a black plastic sink washer to the bottom of a sink in order to keep a sink hose sprayer in position. It worked. I did have to build scaffolding to keep in in place over night, but it did the job. I also used it on my tennis shole. First thing that worked on my tennis shoe.

    Used this on return lines on an in ground pool. Didn't want to cut out the pvc and replace. Put around the joints and within minutes there were no more air leaks. Love this stuff.

    Follow The Directions!!!

    Posted by John Stabile on 10th Jun 2016

    Ok, I have read all of the reviews, and I will tell you my experience with this product. It really works great. Read the instructions carefully. Do not cut any corners. If you do, then you have wasted your time and money. The hardest part is, to know when the glue has setup enough before you apply the glued patch. Temperature has a huge effect on how quick this epoxy will setup. If you apply the patch too soon, then the patch will want to move around due to gravity, and will thin out the glue on the patch. If you apply the patch too late, then the epoxy will not adhere to the area you're wanting to patch. Sanding is also extremely important. If the surface is not clean from any algae and not roughened, it will not bond to the existing surface. All epoxies require a roughened surface on both the patch and the area to be patched. This product is no different. If you're on a time constraint, put the patch job off. If you have any questions, and there are no stupid questions, call Al at the main phone number. He is very knowledgeable and easy to talk to. 2 things I wish this product was, black and not white, and pliable. In my case, not having to drain a 5,000 gallon pond and relocating fish, this product is worth it. I may always have issues with the pond liner when the liner gets sub-surface water underneath the liner from excess rainfall, and the patch cannot withstand the movement, because epoxy is generally not pliable. But until technology creates the material I prefer, this product gets my thumbs up. If you get it right the 1st time, then you did better than I did. I learned from my mistakes, which is not the fault of Mr. Sticky's. Follow the directions religiously, and for sure be patient.

    Best Glue I have ever used-Hands Down!

    Posted by Tom on 7th Jun 2016

    I have ordered MR. STICKY'S UNDERWATER GLUE 30G three separate times from this websitre, and I have always received the glue within days of ordering it. I have repaired the gunite on the bottom of my pool using MR. STICKY'S UNDERWATER GLUE 30G. The hardest part of the whole thing was me holding my breath!! I had two spots that that had popped off the size of a dollar bill that I repaired with the glue. it is fantastic. I also glued in several Loop Loc Brass Anchors that had come up from my deck. I can't praise this glue enough-Best Glue bar none!!
