EXTENDER – Paint additive – FUSION

7.99 $X

EXTENDER is an additive that allows the paint to dry more slowly. This gives you more work time as well as the ability to make corrections. The EXTENDER can also 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;


Mix 15 mL to 30 mL together with a pint of FUSION paint. Adding more is not recommended as it will impact your drying and curing time.

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


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 coat 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.


Once mixed with Extender, the Fusion Paint must be used up within a couple of days. Just mix in what you need to complete your piece, remember you can always add more if needed!
