How to seal the cracks under my garage door?

[lovemachine]

I have mice coming into my garage. And the concrete floor is cracked a bit under one of my garage doors. Large enough cracks for mice to get in.

I already have a new rubber piece mounted to the bottom of the door itself, but it's not enough to cover the cracks in the floor.

I found this:
10 ft. Gray Garage Door Threshold Kit-51010 at The Home Depot

Is that the best method? Or does anyone have any other ideas?

Can't you just get some grout mix and fill the cracks in the concrete? If the crack is big enough for mice won't they just go under the threshold?

Before you glue down the threshold seal i suggest filling the cracks first with Concrete sealer that is SELF LEVELING. Like this example or something similar, remeber it has to be/say SELF LEVELING.

Available Sizes: 10 fl. oz., 28 fl. oz.

Color When Dry: Limestone Gray

Loctite® PL® S20 Polyurethane Self-Leveling Concrete Crack Sealant is a professional grade sealant for concrete. It is a one component, polyurethane, self-leveling sealant for contraction / expansion joints and cracks in concrete floors and decks.

Its abrasion and tear resistance makes it ideally suited for applications exposed to pedestrian and vehicular traffic.

Steel wool slows them down for the most part. The ^ suggestion is recommended.

How well does the loctite work?

I used a similar product in bulk form for a large crack in my porch and it worked very well, after I repaired the crack I painted over it just to make me feel good, but you probably need to find a couple days of "warm" winter weather
