Concrete Base Drying Time

[boatmad]

Hi

I am in the process of having a conservatory built and will need to level the floor with self levelling compound.

The concrete base was installed in early March but because of lockdown the conservatory walls and roof were not completed until 20th July meaning the base was left open to the weather until that date.

The question I have is how long do I have to leave the base before applying primer / self levelling compound.

Thanks

Be worth checking the floor has fully dried from rainfall- put a bit of dpm on the floor, put something heavy on it (bag of cement is ideal), leave overnight. If under the dpm is damp when you lift it, leave it a bit longer before sealing
