Annie Sloan Lacquer is designed to go over Chalk Paint™ for wood or concrete surfaces. This is clear matte lacquer, but there is a very slight sheen because it offers some strength. A matte finish is generally less strong than a shiny finish. As a guideline, we suggest this will cover approximately 12 square meters. This will vary according to the absorbency of the floor. Lacquer is not suitable for areas of high water such as bathrooms. Results may vary depending on previous treatment of surface.
