Moisture in your home can do a lot of damage. Because of this, you will need to do all you can to keep it from entering. While you might think mainly of leaks from your roof or pipes springing leaks, there are many different ways for water to make it into your home. One important part of your home that protects you from water is a vapor barrier. Vapor barriers can come as a polyethylene plastic sheet, a paint or even paper. They are installed to prevent water from travelling freely through the walls of your home. Depending on the type you have installed, it will need a different type of care, but in the end it all comes down to a simple fact. A barrier that doesn’t cover well is not going to be effective. A rip in your plastic or paper sheet will impact its effectiveness, just like an area where the paint is scratched off won’t serve as an effective vapor barrier.
When installing sheets, care needs to be exercised so as not to rip them on a nail or something similar. When applying the paint, complete coverage is vital.
