Tired of nasty winter weather making a mess of your garage floor? It's time to say, ?mess no more!? Here's how to make a garage floor dam that says: ?mess stopper, that's what I am!? From deep within the Carey brothers? vault of holding back can be a good thing, it's dam good ideas that we bring. You can keep winter snow and slush that melts and makes puddles from running and spreading all over your garage floor by creating a dam around three sides of your car. The dam will contain the mess and channel it back out toward the rear onto the driveway -- outside where it belongs. The easiest way to accomplish this is to lay a single bead of minimum expanding spray-can foam insulation across the front and down both sides of your car. It will last all winter, and can be easily scraped off in the spring. Want a bit of extra protection? Add cement sealer on the floor under your car.
