Filler not drying completely

[Sef1928172]

Hi

I have recently used toupret external filler to fill a bit of my front wall where the render had chipped off. It was about 1cm deep.

After several days (of not the dryest weather), there is a patch that has not dried out. See the pic below.

Can anyone advise why this is? Is this going to just pop off soon?

Should I go over with another coat to ensure it is sealed up from any external moisture getting in?

Am guessing any paint I put in there won’t last in it’s current state?

Appreciate any tips for doing a better job next time.

Thanks

Did you cover to prevent weather getting to it?

I did not. I had hoped it would be sufficiently dry to keep water out when the rain came along.

If that is the issue, will it dry out eventually if the weather remains dry?

Thanks

Until protected by paint it can absorb moisture .
