When it comes to sealing air ducts, putty is the go-to choice for many homeowners. This is because it is easy to use and doesn't leave a residue on your hands. Duct sealant is a soft compound that is often compared to clay and was originally developed for HVAC purposes. It is designed to create a seal that blocks moisture, dust, and air movement, as well as block noise.
It is also non-conductive and non-corrosive, meaning it won't dry out and can be easily removed, reshaped, and reapplied when needed. Duct sealant is primarily used for sealing air leaks in air ducts, rather than pipe leaks. However, it can also be used to protect areas with electrical connections or to ensure that outlets and switches are safe from nearby water sources. When using duct sealant, make sure to read and follow the instructions that come with the product for best results. It will be necessary to allow the putty to dry and cure for 48 to 72 hours before turning the air back on. If you're looking for an easy way to check the sealing of your home's air ducts, you don't have to pay for a service.
You can do it yourself if you don't mind going up to the attic. There are products available that use patented technology to pressurize, identify and seal each of the leaks in the home's air ducts. Alternatively, you can hire a professional home air duct cleaning service who will seal the air ducts from the inside using special equipment and technologies. Plumbing putty can also be used for sealing faucets during plumbing installation, but it is not suitable for sealing threaded or unthreaded water supply pipes, which suffer pressure when water flows through them. In conclusion, duct sealant is an effective way of sealing air ducts without having to worry about getting dirty afterwards. It is non-conductive and non-corrosive, meaning it won't dry out and can be easily removed, reshaped, and reapplied when needed.
