If you have a metal roof in your home or in the industrial setting then you must choose the paint for such a roof with caution. It could prove to you to be expensive if it is not done the right way. Since this paint is not available in the local hardware store, you may have to get it especially on order. So, if you want to get metal roof painting mi done with durable and long lasting effects you must bear following points in your mind
- Determine the material: there are a variety of metals that are being used as roofs. So, it is important for you to determine the metal type of your roof before you can start the process of painting it. Different metals undergo varying amounts of expansion and contraction during summers and winters respectively. The surface of the metal undergoes any change in dimension due to change in temperature, the first. This may lead to the cracking of the paint. As soon as there is a change in temperature, it will cause a considerable change in the dimension of the metal roof depending on the time of the day and the weather of the year.
- Know your paint: you must choose a paint that has the property of expanding and contracting with increasing or decreasing temperature. It is important that the paint has the same expansion and contraction as that of the metal roof. This will prevent the paint from leaving the metal surface due to the difference in the expansion coefficient of the two. If the coefficients of expansion are not similar, the paint may crack and chip off. This expansion should be same for the primer as well as the top coat for a better life of the paint.
- Choose the right paint: for the paint to last long, you must choose the right kind of paint for metal roof painting mi. It is always better to choose acrylic paints that are water-based. This is designed to be used on metal and if at all it spills you can easily clean it up. Many people may say that solvent based products are more durable, but the water based paints are less brittle and also environment-friendly.
- The life of paint: if you follow all the instructions of the manufacturer the paint would last not less than 10-12 years. Though no manufacturer gives any guaranty of life of paint but still, generally it lasts quite long. The life of the paint is mainly dependent on the way it has been applied to the walls or metal. If you follow the industry guidelines, the paint will last very long. Also, the life of the paint depends on n the temperature and its variation in your area. If the temperature sees a lot of variation, the paint is bound to crack and have a shorter life span. So choose your paint wisely and remain stress-free for a very long time.
