Used this to fill the seam between the hull and deck. Used an electric calking gun allowing for controlled flow into the seams which were 22ft runs from stern to bow. took two tubes of Silkaflex. While fresh it was easy to use a scraper to push this material deeper into the seam and simple to remove excess leaving a smooth seam level with the deck. It took several days to harden to my satisfaction and in the meantime collected a layer of dust onto its surface. Once painted there is a subtle but clear discoloration showing through the paint. It's a good product but as this was a restoration job on a classic wooden boat I think epoxy would have been a better choice. But, no complaints with how this material works and I'm sure it will hold up for some time as the hull and deck flex a bit with movement and with the natural swelling and shrinking inherent in wood.

This is a very good product. It would probably stick to water. D

I bought this Sika 291 to repair an aluminum canoe. This marine urethane is basically the same thing that SportsPal sells in their repair kit. I haven't used it yet but based on other reviews it will be fine for the repair I set out to accomplish Regarding other reviewers stating they received out of date or wrong colour product, I ordered black and got black and the use by date was 9 months into the future (July 2025) beyond my purchase date Nov/2024.

I used this adhesive to bond a sonar transducer to the bottom of a fishing kayak after watching some helpful videos on You Tube, it does as advertised and created a strong bond and there is no signal interference whatsoever.I would suggest bonding and orienting the transducer while the kayak is in the water so you can match the actual depth and the reading on the sonar as it needs to be oriented perfectly.
