Frequently Asked Questions

Q: What surfaces can this RTV silicone gasket maker be used on?

A: This high-temperature black RTV silicone gasket sealant is designed for use on metal, rubber, and other common engine surfaces. It is ideal for sealing engine gaskets, valve covers, oil pans, timing covers, and other automotive joints where a secure, flexible bond is needed.

Q: How long does the RTV silicone sealant take to cure?

A: As a Room Temperature Vulcanizing (RTV) sealant, it begins to cure at ambient temperature immediately upon application. Full cure typically occurs within 24 hours. Avoid running the engine until the sealant has fully cured to ensure the best seal.

Q: How much sealant is in each tube, and which size should I choose?

A: Each tube contains either 50g or 85g of silicone gasket sealant. For single repairs or small jobs, one tube is generally sufficient. Ordering a 2- or 3-pack is great if you perform regular vehicle maintenance or want to keep spares on hand for future use.

Q: Is this sealant safe to use indoors or in a home garage?

A: Yes — this automotive sealant is formulated to be low odor, making it more suitable for use in home garages compared to many traditional sealants. However, always ensure your workspace is adequately ventilated and follow safe handling practices. Refer to OSHA guidelines for working with chemical adhesives.
