Fusion Extender

Regular Price$6.99

Fusion Extender is great for those who want a longer open time with the paint, to help minimize the look of brush strokes and to extend drying time.

Painting in a dry climate or a space with low humidity? You may find your paint dries too fast. Buy yourself time with our uniquely formulated non-toxic extender – simply add it to the paint and you’ll have more time to brush back and forth to get the look you’re after!

The recommended ratio of 15 mL per pint (500 mL) of paint.

Using too much of this product will increase drying time substantially, but also increases cure time.  Add a maximum of 10% of the original paint volume.



Application Tool: Drop in to paint

Location: Interior/Exterior

Re-coat Time: 2-12 hrs

Dry Time: 2 hrs

Clean Up: Water

Coverage: 1 bottle is good for 2-4 pints. Adding more is not recommended as it will impact your drying and curing time. The recommended ratio of 15 mL per pint (500 mL) of paint.

Recommended Uses: To increase the open working time of acrylic water-based paints and finishes like Tough Coat for no brush strokes

What It Will Look Like: Fusion Extender is a clear liquid and doesn’t change the colour of your paint.

Cure Time: Using Fusion Extender does increase the cure time and dry time of your paint.

How To Use:

Add no more than 10% extender into your paint. 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. It is 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.

What do I use Fusion Extender for?

Fusion™ Extender is used to “extend” the open time of Fusion Mineral Paint™ - meaning it takes longer to dry. People use it mainly to help avoid brush strokes and to help make blending really easy.

How do I use Fusion™ Extender?

If you’re doing a large piece, mix 1/4 bottle of Extender into a pint of paint and mix well. It is recommend using only about 1 part Extender to 10 parts paint (10 mL of Extender to 100 mL of paint).

I want to use more than the recommended ratio, what will happen?

The more Extender you use, the longer it will take to dry. If you use too much, you could end up with a drying time of more than a day! It will also increase your cure time, which means the paint will take longer to get to its most durable state.

Why does using the Extender make the curing time longer?

The Extender has propylene glycol in it, which draws water toward it. Because it likes to hold onto the water, it takes a long time for the water to evaporate from the paint and cure. The more Extender you add, the more water it holds, and the longer it takes to cure.
