Repairing a staircase

[OlgaK]

Hi Bunnings Workshop team,

I have an outdoor staircase with two sections. The upper section is in better condition, but the lower one is more damaged.

I need to fix and refresh the stairs and a few steps. What would be the best and most budget friendly way to do this?

Replacing the steps fully isn’t an option, as it would mean taking the whole staircase apart, which I can’t do.

Some steps have cracks and gaps up to about 1 cm.

Thanks in advance for any tips.
