Thompson Sandblasting & Painting has been serving the South East South Dakota, North West Iowa & South West Minnesota since 1987. Sandblasting is a process in which sand, glass beads or some other medium is shot at high speed through a machine across the surface of a hard material until it is sanded smooth. Sandblasting is often done to remove a previous finish on an item, to remove rust, or to prepare a surface to receive a new coat of paint. The kind of medium used to blast the surface depends on how difficult the removal is and how much impact the material can withstand. So save yourself some time, money, and energy. Hire a professional painter today so you can enjoy the finished project tomorrow.
