Chemlink M-1 (Gray) Structural Adhesive Sealant 10.1 oz Cartridge (1 Tube)

Easy to apply and very sticky. Not that difficult to remove from fingers and hands. Sealed minor cracks in cinder block walls for me and has kept the water out of the house and from entering through windows. Sticks to old cinder blocks, painted block etc. I painted over it the next day with no problem. I also used it for a couple painting and bathroom projects and a caulk/seal on roofing material. A++ in my book!I bought 7 tubes this past August and it worked well. I was about to run out and I ordered 5 more. I received 6 and a thank you card. Thanks for the extra, and may God bless you for your kindness!

I’ve used this caulking on my roof at work from small leaks to the larger ones and haven’t needed a roofer in years. It has also worked on my camper roof. Great product and I will definitely buy this again.

I put this in a rusty old metal gutter that the landlord would not replace. Some of the holes were big enough to be almost waterfalls. Live in the northwest so we’d get lots of rain. All of the holes that were patched held through the winter.

The glue worked perfectly for putting back a couple of fallen tiles from my jacuzzi wall.

Best stuff for sealing gutters and it lasts a long time. Pricey so four stars.

This is what they use on pontoon boats to seal the aluminum skin in between the pontoons

I purchased this M1 adhesive to glue my pool tiles back onto my Gunite pool. It’s been multiple weeks and none of the tiles fell off. I am very satisfied with the product and would buy again.

Strong sealant that cures with in 30 minutes or less depending on ambient temperature. Used this to seal around the holes for an inlet and outlet valves for a stock tank pool. No leaks!
