Using this crack filler is easy. First, make sure to shake the quart - sized bottle well. Then, snip the top of the bottle to the width you need for filling the crack. Carefully squeeze the bottle to fill the crack in your concrete surface. After filling, just let it dry. Remember, different colors of the filler are for different types of concrete surfaces: brown for exposed pea gravel concrete, gray for exposed gray chipped limestone concrete, and white (light gray) for broomed swept concrete. Keep it in a cool and dry place when not in use. Also, check the technical and safety data sheets for each color before using. This filler will give long - lasting results when used to seal your concrete.
