How long to leave mortar repairs to dry before covering with filler?

Afternoon folks

I've been doing some filling around the house. Some of it was quite deep, so I've used mortar for the bulk of it and will finish with filler on top. How long should I wait for the mortar to dry before using the filler?

Cheers

Till it looks dry, indoors with heating on it shouldn't take long at all. It'll go a light colour when it's dried.

Thank you. It looks to have dried pretty well and is certainly lighter in colour, but to be on the safe side I'll put the filler down and wait a little longer. Wouldn't want to have to do it all again and there's plenty of other jobs to crack on with!

Cheers
