785 Manhattan Grey 310C | Strong ceramic and porcelain adhesion, with mould resistance and a tack-free finish in 1 hour.

Very good

Just as described and works great

Was not clear on the page that this doesnt come with the nozzle - so take note if you're expecting one like I was, the money saved to somewhere like Screwfix may not be worth it. Luckily I re-used an old nozzle. Other than that product performs well on application, time will tell to see if it performs well in bathroom and its longevity.

Made my bathroom joints tighter than my bank account after payday. I grabbed this Dowsil 785 in Manhattan Grey because my old sealant was basically giving water a free “back-door pass” into the walls. That old stuff was patchy, saggy, and about as reliable as my late-night DIY skills sober… which is to say: not. Once I squeezed this 785 out, the silicone lay down smooth and confident — like it knew exactly where it was meant to go. Within an hour it was tack-free, and within a day it felt like I’d welded the joint shut with silicone-grade Kevlar. It sticks to porcelain, tile, glass and other slick surfaces like it’s using industrial-grade superglue, but stays flexible so when things move a bit under weight or temperature it doesn’t crack. Handy when showers, baths, or sink units shift ever so slightly. The built-in mould and bacteria resistance feels like a bonus bodyguard against mildew, E.coli, and general damp nastiness — perfect for bathrooms, kitchens or any damp corner you don’t want turning into a fungal rave. Five stars. If sealants were judged by how smugly they repel water and dirt, this one would be strutting the job site in a suit.

Perfect for my needs.

Wouldn't use anything else, best Sealant make in my opinion

I know this is a top quality product but wish I’d bought from screwfix as it came without a nozzle. So if I never had one I wouldn’t be able to use it.

Always use Dow Corning, great flow and adhesion.
