Carts & Millie Suffuse Mineral & Clay hybrid paint in NOIR is a lovely charcoal black.
 
Suffuse meaning is to spread through in liquid and light. It seemed a pretty fitting name for such a delicious paint.
 
The paint is applied like any other mineral paint. It has a slightly longer open time than mineral paint meaning it's easier to blend with and can be reactivated like clay or chalk type paint for a short window of time, depending on your substrate can be reactivated up to 8 hours after drying. 
Once dry, it will dry to a very matte finish with semi self-levelling.
It is a velvety smooth paint which will require sealing. 
Leave to dry at least 24 hours prior to sealing and allow up to 28 days to fully cure.
