Fusion Mineral Paint Extender

Fusion Mineral Paint Extender

Extender works by not allowing the paint to dry quickly, therefore giving you what’s known in the paint industry as “more open time”, which is more working time with the paint before it dries. Extender can help eliminate the appearance of brush strokes.


  • Makes Fusion Mineral Paint and other water based paints flow more smoothly
  • Reduces brush and roller marks
  • Reduces wear on spray guns
  • Cure time may increase depending on how much extender is added.
  • This eco friendly version does not add additional VOC’s!


Mix 1/4–1/2 a bottle of Extender (15-30ml) together with a 500ml pot of paint. 1 bottle of Extender is good for to 2-4 500ml paint pots. Adding more is not recommended as it will impact your drying and curing time.  Once mixed with Fusion Mineral Paint, apply paint as usual. You will notice a longer open drying time, thus giving you time to work with the paint and smooth out brush strokes. Once your first coat fully dries, apply a subsequent coats as needed. We recommend waiting at least 4 hours between coats when using the Extender. Should you notice that applying your second coat is lifting off the first, either too much extender was used, or it needs more time to dry and cure before applying another coat.

Prep your piece as you would to paint with Fusion Mineral Paint. Clean your piece with TSP and give it a light scuff sand.
