Can You Paint Over Drylok Fast Plug?
The cement-like color of Drylok Fast Plug might not be aesthetically pleasing for a lot of people, so wanting to paint over it is not uncommon.

Drylok Fast Plug, like most hydraulic cements, can be painted over once the area is completely cured.
How Long Does Drylok Fast Plug Take to Set?
Drylok Fast Plug typically takes between 3-5 minutes to set. However, humid and cool temperatures can prolong dry time, so keep this in mind. Another factor that can extend cure time is using cold water instead of room temperature water for the mixture.
Before applying the Drylok Fast plug, you need to make a mixture of 3 parts Fast Plug and 1 part water. For instance, if you are using 3 cups of Fast Plug, you should only use one cup of water. Stir thoroughly until the mixture becomes warm to the touch. That’s a clear sign that it has started to set and this is when you start counting your 3-5 minutes.
Alternatively, you can mix and wait 1 minute before applying.
Because Drylok Fast Plug sets really fast, it is advised that you mix in batches so that you have just enough to use at once.
