Hello BNPH,
This depends on the application temperatures and thickness that was applied. Within 1-2 hours it is typically ready to be painted over (emulsion). If this has been used externally, there should be no direct water contact for atleast 5 hours due to being water-based.
If you feel you have met these requirements, please email online@screwfix and we can look into this further.
Thank you for using Screwfix Q&A.
A.K.C.
