SikaSikaflex 291i – Marine Sealant and Adhesive – Specifically Designed for The Marine Market – Solvent Free – Black – 300ml Cartridge

Excellent product,HOWEVER it was delivered in a slightly padded envelope, so the base of the metal tube is all bent and no nozzle was supplied, not the products fault hence the 5 stars but disappointed with the supplier

Tube was easy to use in my application gun and spreads pretty good nice and smooth. Very messy for hands so ensure you wear gloves you can throw away after use. It glues well to your hands and taking 2 days to fade lol.But seems to have done a good job fixing both of my hatches down onto my kayak.Had a slight leak in the seals thought I'd fix it in readiness for next season.I read great reviews and this is mentioned as the best as its designed for boats and has resistance to salt water and fresh all good, the adhesion to plastic was reviewed as really good on other Google review sites not amazon by the way.I've water tested my kayak with water around the seal a good finish no leaks then I chucked z good size bucket of water as a sort of pressure test gave it a good dowsing of water all good no leaks ... I'd tell anyone to buy its worth the extra money. How long will it last hoping few years, plenty left in the tube.Drying time not on the tube but reviews on a Google search said 24 hrs mine was curing in few hours and after 16hrs I was water testing it so its decent.Just messy be prepared to get this stuff in places you didn't want it.I applied a bit too much and white spirits helped clean up a bit.You don't need loads on lesson learnt the second hatch I fitted to my kayak I used less and its sealed well be aware when you apply force if doing a kayak excess Sealand also goes inside the kayak so I got it on my arms and hands without realising it had gone inside kayak hatch rim lol.Enjoy using it havd gun and if fitting to a kayak hatch like me it's good buy it just take it from me less is better.. Next time thin the amount out on kayak lip... im not a robot really used this gloop highly recommend if you need eater tight. Kev

Good marine sealant using for long time

Used it to stick a steel keel band on a dinghy.To make it fit and compensate for the titchy screws.Discovered after opening the tube, and reading somewhere, maybe on the tube that 291i has a big brother 292! Who sticks twice as fast.Somehow missed that when I was looking Sika up to begin with.

We are hoping this product fixes the gaps between antique wooden flooring now time and walking over the floor will tell

Have used this product often and would certainly buy again.Most recent was on my boat in an exposed area and has done the job well.

Sticks anything to anything or anyone.Doesn't give a damn about anything water or other liquids have to say.You can repair almost anything with this stuff, from skateboard shoes to shower cubicles to super yachts.You cannot live without this, if you have been living without this then your life to date has obviously been a dull and meaningless void.Buy immediately without a further thought.

Dud the job.
