Red Jaemtland Limestone from Sweden can be used outdoors in certain applications. This type of limestone is known for its durability and weather resistance, making it suitable for exterior projects such as outdoor flooring, paving, facades, and wall cladding. However, it is important to consult with a professional stone supplier or architect to ensure that the specific variety and quality of Red Jaemtland Limestone you are considering is appropriate for your intended outdoor use.
