Sikaflex-295 UV White – UV & Saltwater Resistant Marine Adhesive Sealant, 3 oz Tube – Paintable, Sandable, Bonds Organic Glass

Works great! I bought this glue to fix the windows on my boat, and it worked perfectly. It’s strong, easy to apply, and dries clear, which made the job look clean and professional. Even after being exposed to water and sun, it’s holding up really well. I’m very happy with the results and would definitely buy it again for future repairs. Highly recommend it for anyone needing a reliable, waterproof adhesive!

Everything as ordered

This product sucks. I'm in marine repair biz. I usually use Dow Corning 795 adhesive silicone for boat windows, when polycarbonate or acrylic is to be mounted and sealed. Never had an issue, my always go to product. But then C19 came along and my local supplier was closed so I opted for Sikaflex 295 to remove and reseal large acrylic cabin port light in a Hunter 40. I'm pretty anal about prep, removing all previous adhesive/ silicone and back painting, etc. Using mechanical #10 SS Fasteners to reset the large ports, over drilled, counter bored inside and out...it leaked. Just a few drops at the top. Not good enough. I pulled all 36 fasteners and the entire 4+ foot acrylic panel literally fell off. Zero adhesion. On the port side there was a leak also however 50% kicked and adhered like devil glue. The port side actually broke trying to remove it. I contacted Maritime Plastics here in Annapolis since I was now on the hook to replace the ports ..on my tab. They were surprised that Sikaflex 295UV was still on the market and told me their biggest factory recall job was a batch of Binary Offshore hatches, 60+ were sent to them to rebed when Sikaflex 295 UV failed in new construction. They use GE adhesive silicone and never have issues. Bottom line, I ate that job by using this product and will NEVER use it again. Dow Corning was used on the second go round and NO ISSUES.

Easy use, fast cure. Reasonable marine price.

The product is AMAZING! I highly recommend for bedding hardware in marine applications where you want a good seal and you want the white to stay white. That said, the tube of sealant was poorly packaged (loose in a cardboard box with some crumpled paper). Worse, my tube arrived WITHOUT the screw on tip…. I needed it for a project next day so had to scour Ace Hardware for a tip that would fit. BTW, the tip for GOOP sealant has the same fine threads as the sikaflex. Again, great stuff, but maybe not the best way to get it.

This is excellent for my boat, but these clowns sent a damaged tube, no nozzle. Package was not damaged so they actually put a damaged tube in the box and shipped it. Buy this caulking ..... from someone else.

for a small sealing job, this avoids the inevitable waste of opening a full cartridge

It dries fast so make sure you get whatever it is you're adhering into the proper position as quickly as you can after applying this.

The front glass of my boat had recently gotten loose and threatened to come off completely. This adhesive is resistance to outside elements which is what convinced me to give it a try. The results are fantastic! If you own a boat and need to fix something on it, this Sika product is top notch.

I'm a big fan of Sika products in general, and having repaired a convertible rear glass with a very similar sika product in the past (which is not available at the moment), I decided to go with this one for a similar repair on a different car. Turned out great, this adheres very strongly once cured (go for the full 24hrs or even more if you can) and the seal is now completely leak-free. The added "uv resistance" is certainly a nice feature. Do bear in mind that this stuff is extremely messy to work with, and will stain anything it touches (including fingers) so proper preparation, protection and care when applying are most recommended. That said, once cured, it's fairly easy to scrape any over-application off the glass with a razor blade (DO NOT try to remove/cleanup any of it if it's not completely cured, you'll end up with a huge mess... Ask me how I know! ). There's very little smell/off-gassing/VOCs, so working in an enclosed area is not an issue. OH, as other reviewers mentioned, the little plastic applicator tip was missing, which is a bit of a bummer but not catastrophic by any means as any tip from standard silicone or caulking tube will do. This tube does fit any standard caulking gun, and I don't see how you could apply it without one.

The caulking was great, The plastic tips which are pictured weren't in the package. That was annoying and difficult to find elsewhere. Held up my project from getting done in a timely manner

We just purchased two of the Silkaflex-295. My husband loves this product. He said it's easy to work with and worth every penny. Just as I was going to write this review I noticed that many reviews mentioned that their delivery was missing the plastic applicator. Well we received one with and one without. I'm not sure why this is happening but they were very quick at sending a replacement. Hopefully this issue will soon be resolved for future orders.

The product has an expiration date of may 2026. Not yet out of date but one would expect more than a few month shelf life.
