Why does my sealer blush out when it rains on it and then dry back clear?

Ask a Pro

Hi Earl,
Hope you are well. I watched all the videos, asked you a ton of questions and ordered the artist grade interior stain kit. My project involved smooth concrete on a porch covered by an awning. On the website I did not see a specific difference between the products for interior and exterior projects. I have stained the porch with Riverstone, neutralized thoroughly and put on my first coat of sealer. We have had tons of rain so I am waiting for the opportunity to put down the second coat of sealer. The first coat of sealer is more shiny than expected but not bad-the Riverstone color is perfect! I was very careful to put down a thin coat of the sealer.
The sealer dried for a couple of days before the next rainstorm. The awning is not up now (but will be soon) and when it rained the porch got very wet. I noticed some small pooling and where the rain pooled, it looked like fresh sealer, kind of blue and milky white. I left the areas alone and the rain dried and everything looks fine. Is this normal? Does this mean the sealer is not completely dry yet? It provided a great surface, not slick and it isn't sticky-maybe the humidity could be affecting it? It will be at least a week before I am able to put on the second coat of sealer...
Along with the interior kit I received the wax which I ordered in a matte finish. In an earlier response you suggested waxing the porch since it is covered. How long should I wait to wax after applying the second coat of sealer?
I am very pleased with the Concrete Camouflage product line and my porch looks great! Just want to make sure I am doing everything correctly.
Thanks for your time (again!),
Please take a look at our article on blotchy sealer issues.
I hope this helps,
