Invisible Oil Primer is a water-based wood primer with excellent adhesion, that gives wood a matt, untreated appearance when combined with WOCA Invisible Oil. Invisible Oil Primer is the first stage in a high quality water-based oiling system and should therefore be used together with WOCA Invisible Oil. The Invisible system has been developed for use with light wood varieties, where a high quality oil and newly-sanded, untreated appearance is required. The range gives the floor a surface that is both comfortable to walk on and soft to the touch. The floor is also left with a soft, water-resistant surface that is easy to clean and maintain.
