Description

Pro Grade RTV Silicone Sealant (Multiple Colors & Fixed Nozzle)

For a sealant that truly lives up to its Project 1 "Professional Grade" name, 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. 

Easy application is a major plus to our Pro Grade RTV Silicone Sealant, 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, and aluminum.

    Pro Grade RTV Silicone Sealant

    Just what I have been looking for to set and seal the Portlights (windows) on my boat. Even with a fix nozzle it laid a nice thick bead. Nice squeeze out when screwed down firmly. Very reasonably priced.
