Thank you for your question.
Either Watertite product should be fine with your adhesive. We recommend testing the paint on a stir stick first. Allow for full cure, which is 7-14 days, depending on temperature and humidity. Once cured, apply your PL300 adhesive to the stick and see if it dries and sticks. If your test is successfully then you should feel confident that the adhesive will stick to the painted concrete.
We hope this answers your question. Feel free to contact us again if you require further information.
