Sika – Sikaflex – Pro-3 Purform – Polyurethane Sealant for Floor Joints and Civil Engineering Applications – Results in a Flexible Seal – Black – 600ml

This stuff is fantastic. Thick and dense like black pudding from hell. I used scraper to apply it otherwise you will end up with Sika on your gloves and that's it. Press hard and it will stay in place. Used on my chimney to seal it and hold it in place. Great stuff. As soon as you apply it, then it's sealed and water proof. Very sticky and I mean very sticky. To get Sika out of the sausage package at the beginning is not that hard but as soon as you get to the end of it - its a strong man exercise mission. Definitely recommend. Good luck 🤞

I like the product Do the job perfect 👌

Very difficult to work with, the recommended delivery device is useless given the products properties. Literally spent days trying to get it off my hands.

The grey sealant is great to use as described, and very responsible and responsive seller, thanks a lot
