Hemway Construction Light Grey Sealant & Adhesive 300ml - 1 Pack | All-In-One Hybrid Polymer, Superior to Silicone Sealant, Waterproof, Odourless, Anti-Mould, Paintable, for Indoor & Outdoor

Plugged the hole i needed it for. Waterproof and hasnt leaked so i assume its good quality and durable. Straightforward to use simply insert into silicone gun and snip the end off. Colour is indeed jetblack.

Exactly what I required, correct colour, delivered on time. Very tough when cured.

Seems ok

Used for sealing my fishing bait boat, it’s quick dry and does the job.

Easy to use, goes on great and drys quite quickly.

I'm sure this sealant works - but getting it out of the tube is an issue ! The stock was manufactured in March 2024 and may therefore be a bit old, but even with the nozzle cut to give a thick bead I had to use both hands on the steel dispenses to get anything out. I will try it with my cordless caulking gun to see if that can extract it without bursting the tube. Disappointing.

Good product excelent service reasonable priced.

Don't very often use sealant but this went on a treat and looks good

Resealable tip is very pleasing and the tube itself high quality. I pumped countless tubes of caulking. The "Hybrid Polymer" proclamation was new to me. Everybody wants to be unique. This is polyurethane, not silicone. Like silicone, it comes in a plastic tube and pumps out with a high sheen, but its similarities to silicone end there. This caulking is like any other high quality polyurethane based caulk. It is sticky and does not like to be worked. It is not overboard like a butyl caulk. Have paint thinner ready if you can't make any mess. It compresses and eventually drips from a drip-free caulking gun. Overall, I am happy.

Worked fantastic, used for gluing together flowers made from upcycled glass and dishes. Held all pieces together thru rain and high humidity. Have not tested thru the winter months yet. Live that it dries clear and easy to apply. Let dry indoors for 48 hours before hanging outside.

This product did better than expected.

Just put it in my chicken coop. So far it’s great! I’ll update if it doesn’t hold up but I foresee it lasting. Also painted over it and it was seamless. I actually really like the grey colored one because it’s way easier to work with and see.

Très efficace
