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.

Important note: Paint will not adhere to silicone sealant but silicone sealant will
adhere to most painted surfaces. Always paint first and then seal. Make sure the
paint has had time to dry completely before applying silicone sealant.
Great Product and you can't beat the price and availability! I have been ordering this in clear and other colors now for a few years and is always good!
This silicone adheres to anything. We've used it on ICF, concrete, & sheet metal as well as other standard materials. Also had great customer service.
Very good price
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.
Past supplier has been non responsive
Product was fine but color was a bit to light and the texture was much to shiny, almost like aluminum foil. Not suited for my purposes. If it were paintable I would probably have kept it. Please send return address barcode.
very good product and the service is also great
Great product; adheres well, low odor; received very quickly; great price & free shipping on larger orders . Very Happy with purchases so far.
I ordered a box of this silicone and have been very happy with it. The screw in nozzle has been perfect and I can transfer a nozzle from one tube to another to use every last bit of caulk and maintain a consistent bead size. I used these with a powered caulk gun to seal Truscore PVC wall and ceiling panels and it all worked great. Next step is to order another case and seal all my windows.
