The answer is no, General Finishes Milk Paint does not require sealing, especially for lower use pieces such as a coffee table. General Finishes Milk Paint is a high tech mineral based paint created using modern technology. We recommend a top coat if you want to increase the sheen or for more durability in high traffic areas such as a table top or kitchen cabinets. Waxes are optional, and are usually used for style and design purposes. General Finishes prefers top coats over waxes for durability and performance reasons. General Finishes High Performance Top Coat, and Glaze Effects to compliment the Milk Paints. You can also two tone the top with a Gel stain - see Chrissie's Collection page for some fine examples.
