chink up

To fill in or patch narrow openings, such as cracks or fissures (chinks), of something. A noun or pronoun can be used between "chink" and "up." We live in an area that experiences a lot of earthquakes each year, so we've gotten pretty good at chinking up the walls of our house. No, you can't just chink up a huge crack like this. This indicates that there's a serious issue with the house's foundation. Talk to Dad, I'm sure he has some putty or something that you can use to chink up the crack in your wall.
