The standard Coppertone sunscreen says

Directions: Apply liberally 15 minutes before sun exposure. Reapply: after 80 minutes of swimming or sweating; immediately after towel drying; at least every 2 hours

I’ve always heard this as time to absorb to become waterproof, but I’m not sure if it’s actual skin absorption or the liquid used to convey the sun blocking compounds to dry or evaporate. Either way, apply and then wait.
