Yes - we recommend adding up to 10% mineral spirits. You can add more mineral spirits, but test first. The mixture will thin out quickly. Using more than 10% can affect the performance and durability of the finish, but as a glaze, this is not as critical an issue because your topcoat will protect the finish.
