Hi all just wondered if it would be possible for me to use A star nails acrylic liquid but a different product of powder ? thanks for replying

No. although EZ Flow say their Boogie nights powders can be used with any monomer. But no do not mix brands.

Each systems powder has a certain amount of catalyst (starts the cure) in it, that amount is precisely required to complete the polymerisation (cure) of the enhancement. Each system has different amounts of catalysts and different reaction speeds. That is why mix ratio and using the same brand is sooo important.

Kinda like baking powder in a cake, if you don't have the right amount it ain't gonna be pretty.. Hope that all makes sense..
