When you have your little repair project around the house, such as blocking a hole or filling a gap, Haohai PU foam is a good assistant! You might have noticed how it swells up after you spray it out of the can. So how does this Haohai expandable filler foam work?
PU foam is short for polyurethane foam, a peculiar material which expands when it is in contact with air. There are two primary components inside the can that combine when you press the button and spray: polyol resin and isocyanate. When the two ingredients mix, they cause a chemical reaction that generates a gas. This gas gets trapped in the bubbles of the foam, making it expand and grow larger.
Here are a few things to remember to ensure you get the best performance from your Haohai PU foam. Shake the can well before opening to ensure that the ingredients are thoroughly mixed. Then, when you’re ready to clean, hold the can upside down and spray momentarily before each use in order to eliminate trapped air in the nozzle which can lead to the foam drying and clogging it. Clean the nozzles by just wiping it with a damp cloth every after use. Lastly, work in a well-ventilated space to ensure you don’t breathe in any fumes from the foam itself.
Sometimes you may not want the PU foam to spread all over the place, for example when you are working with a cavity. Alternatively, you could wet the area of your project where you’ll be applying the foam to help control that expansion. It will help moderate the expansion. Additionally, you can use a knife or pair of scissors to cut off excess Haohai expanding foam filler after it has dried and set. Practice — apply in small amounts of foam at a time to see how much it will expand.
Why to choose Haohai PU foam? Haohai PU Foam has many more benefits for your expanding. It may also be used to fill gaps and cracks and to insulate recessed and hard-to-reach areas. Once the foam has been cured, it is waterproof, which is great for outdoor use. It also helps minimizing noise and vibrations, creating a quiet, peaceful home. The Haohai expandable foam caulk is extraordinarily light and easy to handle – and that means you’ll be getting less work when using it in your DIY projects.
When using PU foam, there are pitfalls to be aware of. One common mistake is dispensing too much foam at once, causing over-expansion and waste. Another error is squeezing the foam and not wearing protective equipment, like gloves and goggles, while working with the foam. Do not touch the Haohai expanding foam gap filler with bare hands - it will remove just fine once dry. Finally, please be certain to read and follow the instructions on the can to learn how to use it appropriately so you can be safe.
