Our 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.
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.
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.
Mix 1/4 a bottle (15ml) – 1/2 a bottle of Extender (30ml) together with a pint. 1 bottle is good for to 2-4 pints. Adding more is not recommended as it will impact your drying and curing time.
Soap and water.
Prep your piece 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 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.
