    What product should I use to fill cracks in concrete deck?

    There are several cracks, hairline to 1/4" wide, about 2 feet long, in our 10 year old concrete deck surrounding our pool. What is a good product to use to fill them? I saw a Sakrete product at Lowe's. It seemed liquidy and it pours into the crack to fill it. I like that idea, but I don't really know. Thanks in advance.

    A polyurethane caulk will last longer than about anything. It will be very, very difficult to get anything inside a hairline crack but it will do well on 1/8" or wider.

    I would not bother with any masonry product which I assume the Quikrete product is.....it won't flex and you need that.
