Pro Grade RTV Silicone Sealant (Detached Nozzle)

For a sealant that truly lives up to its Project 1 "professional grade" moniker, look no further than our Pro Grade RTV Silicone Sealant. With its impressive durability and flexibility, it's perfect for use in any environment, indoors or outdoors, and it will last for years to come without you needing to lift a finger to reapply. The Pro Grade RTV Silicone Sealant is incredibly easy to apply, with its smooth texture and fluid flow from the detached nozzle. The detached nozzle also makes it easy to switch between nozzles, clean your sealant tube, and dispense as much sealant as you need at any given time. 


Easy application is a major plus to our Pro Grade RTV Silicone Sealant with a detached nozzle, but it is also an extremely durable product. Our Pro Grade RTV silicone sealant can hold up against the elements outdoors, and can easily take wear and tear indoors without looking unappealing or needing to reapply.  Plus, its mildew-resistant properties make it a no-brainer for use in moisture-heavy areas such as kitchens, garages, bathrooms, and laundry rooms, so you can use the same tube of sealant all around your home or your client’s space. 


No matter what you’re sealing up - from bathrooms to basements to attic spaces - you’ll need the right color for the job. We make it easy for you to find what you need at Silicone Depot, since we stock our project 1 professional-grade RTV silicone sealant in multiple colors including clear, white, black, aluminum, and bronze.

    Pro Grade RTV

    Love the detached and longer nozzle. The only thing keeping it from a 5 is no cap to put on the end of the nozzle to save partial tubes. Response from Silicone Depot: Hello, Scott! Sarah from Silicone Depot here. Thank you for your great review! You bring up a great point about the need to save partial tubes. The best way we found to avoid them drying up is to gun out a bulb of silicone so that it looks like there's a little mushroom cap on top of your cartridge and let it cure. While we can't guarantee any silicone that has been opened, you should be able to pull the bulb off and continue caulking. Give us a call if you have any questions! (812) 824-8000
