Thicken or extend your oil paint naturally without toxins and preservatives. Using the same ingredients and techniques as the Renaissance Old Masters, this is a time tested, archival and easy way to create impasto effects or thicken / extend paint.
Watch this video tutorial on "How to mix your own Impasto Medium".
Ingredients: 1 lb. Artist Grade Powdered Limestone Powder
Mix with refined walnut oil or linseed oil to create Impasto Medium.
We ship Priority Mail (2-3 day delivery) for all packages except orders under 14 oz. which ship USPS First Class. We ship within one business day of receiving an order, and a shipping confirmation is automatically sent with USPS tracking numbers for all packages.
All European Orders should go through natural-earth-paint.com
We do ship internationally all over the world and USPS estimates 8-15 days for delivery. You may incur customs fees upon delivery. We unfortunately never know when or if this will happen - it is quite random.
We regret that we cannot provide a real-time shipping calculator on our site since it is cost prohibitive, but you can use the USPS shipping calculator on their website to get an approximate cost and time frame for your delivery. Please contact us if you would like to purchase an expedited service such as USPS Express.
