So, probably a silly question, but I have bought the seche vite top coat

[Swifey]

But do I do 2 coats of varnish like normal, and do I let them dry inbetween? Or just one coat of varnish?

Just paint your nails as normal, no need to let them dry in between. The top coat does slightly shrink the polish, so paint over the top of the nail to avoid a gap at the top.

Amazing stuff, stick it on top of wet paint

Ok great, thanks ladies!
