Paint Extender
£5.99
Our Extender is great for those who want a longer open time with the paint to help minimise 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 – add it to your 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.

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.
WHAT ELSE CAN IT BE USED FOR?
Our Extender can be used with other water-based paint products.
Add it to your Tough Coat for a longer open time and a smoother finish.
Metallics can dry fast adding Fusion Extender helps to get a brushstroke-free finish.
HOW TO USE
Add no more than 10% extender into your paint. Once mixed with Fusion Mineral Paint, apply paint as usual. However, 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, you can 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.

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. We 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 have a drying time of more than a day! This is because adding an extender will also increase your cure time, so the paint will take longer to reach 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.
