I was wondering what forum readers would suggest to fill in horizontal gaps between a front door step and the door. They are not huge gaps. I think its just caused by shrinkage as the house is about 60 years old.

I was thinking something along the lines of a mastic sealant as I want to be easy to use and not hugely expensive. It also goes without saying that it must be waterproof.

The biggest gap is about 5 mm wide the rest are smaller.
