You better do some research before you put a "water borne" product over a solvent base. You should be fine with what you already applied.
Applying a clear coat designed for floors to a vertical substrate is a bad idea. Always check with paint store or manufacturer before using a coating product for other than what it was designed for. My .02 with over 30 years as a painter and 20 as a painting contractor.
