    • Great marine grade sealer

Used this product to seal a freezer ice bath. Product worked phenomenal, was a fraction of the price of comparable products. Easy to use, has held up well for months with no signs of breakdown

    • Great product if you have humidity
Size: 10.1 oz Color: White Number of Items: 1
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. ... show more

    • Dispensing is incredibly difficult.
Size: 3 fl. oz Color: Black Number of Items: 1
The material in the dispenser is great, I've used it in a standard caulking gun for years and never had an issue. I have a small spot to hit on a seam that was about 3 ft long and didn't want to use an entire cartridge so I thought I would try the smaller tube. Let me say that I'm in construction and in pretty good shape, physically stronger than most men. Encounter, and trying to dispense the caulk out of this was incredibly taxing. I struggled for half an hour to caulk a 3-ft line. It wasn't that cold out. Maybe 80° so it wasn't for sure. It was just that the caulk is thick and difficult to use in that applicator. ... show more

Body shop wanted $1000 for new front valance because a tab had broken off. Upon the shop’s recommendation I purchased this and glued the piece in place. Problem solved and you can’t tell the difference.

    • This stuff is the best.
Size: 10.1 oz Color: White Number of Items: 1
I worked for about 10 years in the professional yachting industry in Europe and that's where I learned about Sikaflex. It's the absolute go to for any type of sealant needed on oceangoing yachts. I'm back in the States now and working on a camper conversion project and I've mainly been using Sikaflex, I did try using some regular polyurethane sealant from the hardware store and Sikaflex is so far and beyond a better product. When it's wet it's easier to work with, and when it dries, it doesn't shrink and it's far more durable. I absolutely recommend it. ... show more
