    I was wondering what forum readers would suggest to fill in horizontal gaps between a concrete 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.

    Picture would be useful as it depends what you mean by not huge. If they’re big enough I’d be inclined to fill/point them with a 3:1 mortar mix (or a tub of the ready to mix stuff if you don’t have access to sand and cement without buying a 25kg bag of each), and then when cured paint it with a proprietary step paint. Ronseal diamond hard is good stuff.

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