Re doing topcoat silicone

Hello,

We've just had a blockwork seating area rendered in the the silicone enhanced render (comes in 25kg bucket) from Johnstones.

After some unexpected rain, the seat bases took on alot of water making it go soft before being able to fully cure the recommended 24hrs. Now that its dried out the seat bases have lots of what looks like small pin holes everywhere. The verticals look fine.

Can this be rectified by just going over the seat bases again with the same topcoat mix or will it not bond?

Thanks in advance
