Exterior house painting was completed Wed 9/19 - Started raining very heavily Friday 9/21 and still raining. Will the rain adversely affect the paint n some way? It is Dunn-Edwards Acrylic paint.

If it was warm the day of and the day after the paint should fine, if it was oil then thered be a problem but laytex dries quick, id dare say your house was dry the same day it was painted for the most part, unless it was cloudy or overcast
