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

Are you tired of struggling with applying and reapplying thick, clunky silicone sealants that just don’t work well no matter what you do? Then it might be time to switch to our Project 1 Pro Grade RTV Silicone Sealant. This high-quality yet affordable sealant comes in multiple colors - including clear, white, bronze, black, and aluminum - making it perfect for all your DIY and professional projects, whether you’re sealing up your basement, kitchen, or home exterior. 


Because this high-quality sealant also boasts mold-and-mildew-resistant properties, it’s an excellent choice for sealing bathrooms, kitchens, and other high-moisture areas of any home. Never worry about mold, mildew, or bacteria building up where you’ve laid down your silicone sealant. This silicone sealant is not only a great choice for effectively sealing cracks, gaps, and blemishes on many surfaces, but it’s also the best way to keep you, your family, or your clients healthy in the long run. 


Project 1 Pro Grade RTV Silicone Sealant is also exceptionally easy to apply, whether you’re a beginner or you’ve applied countless coats of sealant. Most silicone sealants are inefficient and difficult to apply. Silicone Sealant Depot’s Pro Grade RTV is thinner than typical silicone, allowing it to flow easily on flat surfaces for simple and quick application. It is soft and flexible until it dries, meaning you won’t face challenges while laying down your bead of silicone sealant and applying your seal.


Silicone Depot’s Project 1 Pro Grade RTV Silicone Sealant is a truly professional-grade sealant. It’s both extremely easy to use and more effective to use than any alternative on the market. So if you want a sealant that’s both effective and easy to work with, try our Pro Grade RTV Silicone Sealant today!
