Description

Select Neutral Cure 100% RTV Silicone Sealant (Detached Nozzle)

Some construction and DIY projects - like those that involve adhering materials to surfaces like vinyl windows, doors, and more - require a silicone sealant that is just a little stronger than what’s on most shelves. If you’re looking for the perfect silicone sealant for specialized jobs, look no further than Project 1 Neutral Cure Silicone Sealant. 

This high-quality, professional-grade sealant can be used to adhere to concrete, limestone, brick, mortar, and more surfaces where other products just don’t work. Project 1 Neutral Cure Silicone Sealant adheres  to concrete, limestone, and other surfaces thanks to its strong adhesion. It’s also resistant to both low and high temperatures and UV rays, making it ideal for outdoor use. 

Because it is a neutral curing silicone sealant, Project 1 Neutral Cure Silicone Sealant isn't just effective and easy to apply, but it also has a minimal odor, meaning that the smell won’t be overpowering when this sealant is applied. It’s perfect for indoor use and outdoor use alike and makes for a simple and pleasant application process that differs from many other non-neutral curing silicone sealants out there on the market. Neutral curing silicone sealants like the Project 1 Pro Grade RTV Silicone Sealant are speciality products that can only be purchased from silicone sealant specialists like our team at Silicone Depot. 

Also note that Project 1 Pro Grade RTV Silicone Sealant is your only choice if you’re looking to work on vinyl surfaces, since other types of silicone won’t properly adhere to vinyl windows, doors, and siding. This sealant will form a long-lasting seal on all of these types of surfaces and will not wear down over time, while other types of silicone won’t even adhere. 

If you’re looking for a 100% silicone sealant for use on masonry surfaces that won’t wear them down or corrode them but also won’t wear away in the long term, Silicone Depot’s Project 1 Neutral Cure Silicone Sealant is a great choice. You can use it on any surface from vinyl to concrete, limestone, brick, and mortar.

    Great adhesion to silicon roof coating

    Great quality for the price. Would have given 5 stars but the color (white) is semi transparent instead of a solid white which made it hard to see while sealing cracks.
