Amazon Customer: Used this to seal up a solar cable gland on a bus roof. Then used it in a few other projects. It has performed amazing in all situations.

Rob H.: It’s great stuff works really well but I ordered 2 white tubes and had one black, one white.
Doesn’t seem to be anyway to complain and receive another so $30 wasted

Don M.: This is an excellent product but I ordered black and white was shipped. I had to make it work because of time constraints so I used the entire tube. Super pain because now I still have to try and hide the white residue 😕
No provision in “wrong item” category for compensation after you have used it. Fair enough but decal on tube said black and on the base of tube it said White .

Colorado: Wonderful, grippy, but gooey to apply - super great adhesion - but absolutely need humidity such as East or West coast, near water, Great Lakes or humid Georgia. I live in Colorado and it is still gooey on my sailboat - called the company - they said need 50-60% humidity or it won't dry. Used in my bathtub and I had to leave hot steaming water in the tube twice and it adhered perfectly. Otherwise would be 5 stars in a humid climate. 2 stars for Colorado - but it's not chemical reaction for drying - it's reactive to humidity.

James: I used this to redo all the outside joints on my RV. First, I removed the old caulk and cleaned the joints with a cleanser and then washed the cleanser off with rags and water, then rubbed dry with a clean rag. Then left the joint to continue to air dry any remaining moisture as moved to another joint. Once air dried as well, I applied the Sikaflex-291 and left the seams to cure overnight.

I found it really difficult to apply and the best way to smooth the joint was dipping my fingers in rubbing alcohol first and then smooth along the seam. Wipe any excess collected on a rag, But always moisten your finger first with the rubbing alcohol before touching the Sikaflex again. (I had no success using soapy water - but rubbing alcohol allowed me to smooth joints or overlap caulking joints.)

Then leave it alone.

It states somewhere in my reading that it can take up 10 days to cure. And I found that to be pretty accurate except for the North side of my RV does not get any sun on it at this time of year. (October) And that side is taking forever to cure - it is still tacky to the touch and 14 days have passed so far. It's curing slowly but on what time table I do not...
