Great sealant
This stuff works great. I have a small shed that can be opened from the top as well as the doors but anytime it rained or snowed it would leak really bad from the top. I brushed this sealant all over the top especially at the seams to try to prevent leaks. In the past 3 weeks we have had snow and major rain storms. When I opened the door to check in side there were no leaks and everything appeared to be bone dry. Would definitely purchase this sealant again

Easy to use, very good product
Easy to use sealant. Thicker product covers well creating a water tight barrier for my wood planter boxes. Dries quickly. Seems durable. Also used on a cement birdbath that was leaking. Sealed it perfectly. Works very well.

Good product
Works great and dries fast. The brush is a one and done use. But other than that, great product!

Easy to use, dried clear and looks good.
I used this on my wood tiles out on the deck. The tiles that you clip together. Only one coat as this was not enough for 2. It covered 3 boxes of tiles. Also because I was on a balcony had to paint from corner to door, second coat would have been problematic logistically. That said, went on easy, dried fairly quickly and is clear. Hoping it will help extent the life of the wood tiles here in CA. Easy to use.

Don’t get it on your hands.
A thick paint, almost a gel, that applies easily and dries in less than an hour. It comes with plastic gloves, but no instructions that say you should use them. I used it to seal a seam in my gutter. Seems to work. But I was up on a ladder. I carried the YKF in a plastic bag. The YKF has an inner seal, necessary because the cap does not pop on to create a seal. I left the inner seal on the ground and thought the cap would seal the container. It does not. On my way down the ladder, the YKF tilted in the plastic bag and some spilled on other tools. I put my hand in the bag to straighten the container so that it would not continue to spill and got the YKF on my hand…a thin coating that dried before I could wash it all away. It left a clear, thin coating on my hand that I am gradually scraping away. It is difficult. So, be aware that the cap does not seal the container…use the inner seal. And definitely use a brush for application and the gloves if there is any chance of your hands contacting the YKF. 4 stars because of the lack of good instructions and a poor cap.

Not quite what I was expecting!😡
First off, I can’t even get the product out of the box just by simply opening it. It seems it leaked out of its container and solidified on the top corner of the box. Now I have to open the bottom to see if I can get it out. Not even sure if I have enough left inside the container to do the project it was intended for… Welp, it looks as if the top is cracked the liquid slowly oozed out. Not sure if there is still some liquid left inside. Still not acceptable!

Great water proofer
Works great! Actually stopped water from seeping through basement walls. Dries clear. No strong fumes. Easy to apply. Will definitely buy more to do other areas in basement. Just wish it came in gallon containers.
