As someone who loves DIY projects and painting furniture, I have always been curious about using chalk paint on my projects. However, I was also skeptical about its durability and protection. That’s when I discovered the idea of using polyurethane over chalk paint. In this article, I will share my personal experience and everything you need to know about using polyurethane over chalk paint.
What is Chalk Paint?
Chalk paint is a type of paint that gives furniture a vintage, matte finish. It is made with natural ingredients, such as limestone and clay, and does not require any sanding or priming before application. Chalk paint is known for its easy application and ability to adhere to various surfaces, including wood, metal, and plastic.
What is Polyurethane?
Polyurethane is a clear, protective coating that is commonly used on wood surfaces. It provides a durable finish that protects against scratches, stains, and water damage. Polyurethane comes in various finishes, including matte, satin, and glossy.
