I was replacing a round junction box on my deck to install better lighting and a small thin layer of stucco chipped off around the box. The area is less then half of the diameter of the box, about an inch in width and about 1/4th inch deep. It is basically a surface that has come off. Can I wait until summer to repair this? I am located in the Seattle area and with the constant drizzle it might take forever to dry?

I am trying to apply [url=https://www.homedepot.com/p/Eagle-5-gal-Supreme-Seal-Clear-High-Gloss-Solvent-Based-Acrylic-Concrete-Sealer-EU5/202374894]this acrylic concrete sealer[/url] to my concrete floors indoors. I am in an industrial loft with concrete on the bottom floor and was attempting to create a high gloss finish. The problem is that, while the sealer is creating a nice, smooth finish in some areas, it is not working properly in others. There are patches where the sealer is [url=https://imgur.com/EnSjUnk]clumping together[/url] rather than spreading evenly across the concrete, as well as patches where the sealer [url=https://imgur.com/QM1J8GB]doesn't seem to be adhering at all[/url]. Lastly, there are areas where the sealer is covering, but with a [url=https://imgur.com/CJRVMeI]bumpy or uneven finish[/url]. The concrete was burnished prior to application, thoroughly cleaned and dried, and had a previous layer of sealer from years ago (to which it owes its color). Does anyone know what I'm doing wrong here, and how to fix this uneven application into a smooth layer of sealer? I have already applied two coats, so additional coating doesn't seem to do the trick.
