As an expert in the HVAC industry, I have seen firsthand the importance of properly sealing ducts. One of the most effective tools for this task is duct seal compound. This material, also known as duct sealing putty, is a must-have for any HVAC technician or homeowner looking to improve the efficiency of their air conditioning system.Duct seal compound comes in a 1-pound package and is specifically designed for sealing electrical service inputs, junction boxes, and other devices where weather resistance is critical. Its mass-like consistency makes it easy to handle and apply, making it a popular choice among professionals and DIY enthusiasts alike. But what exactly is duct seal compound used for? This material helps seal and protect openings, holes, and duct openings against dust, moisture, drafts, and noise.
It is non-toxic, non-corrosive, and does not stain, making it safe to use in any environment.
Types of Duct Seals
There are various types of duct seals available on the market, but duct seal putty is considered one of the best. Its soft consistency makes it easy to handle and install for a variety of HVAC purposes. However, its primary use is to seal holes and leaks in ductwork. Duct sealing putty is perfect for blocking dust, moisture, noise, and air movement from duct holes. It is especially effective at sealing small cracks and gaps and works better than masking tape.And the best part? Duct seal compound does not contain asbestos and does not damage plastic materials or corrode metals.
When to Use Duct Seal Compound
Now that you know what duct sealant is and what it can do for your air conditioning system, it's time to learn when and how to use it properly. Leaky ducts are one of the most overlooked aspects of an HVAC system, yet they can cause significant energy loss. In fact, the average home wastes 20 to 30 percent of airflow due to duct leaks. If you're wondering how to use duct sealant to seal gaps in ducts, it's crucial to use quality materials. Don't try to skimp on the cheapest brands out there.Instead, opt for reputable brands like Rainbow Duct Seal and RectorSeal Duct Seal compound.
How to Use Duct Seal Compound
Using duct seal compound is relatively straightforward. First, make sure the surface you are applying it to is clean and dry. Then, take a small amount of the compound and roll it into a ball. Place the ball over the hole or gap you want to seal and press it firmly into place. For larger holes or gaps, you may need to use multiple balls of duct seal compound.Simply repeat the process until the entire area is covered and sealed. Once applied, the compound will dry and form a strong bond with the surface, creating an airtight seal.
