    It must have been wet or damp. That is moisture coming up under the sealer..

    withot seeing it i would guess its this

    i know this is brickwork but it happens to concrete. i would not worry too much about it as if you driving on it it will wear off pretty quickly

    derek,
    will another coat of sealer fix this

    i thought it might be that or salt coming through but i scrubed a patch with water and that didnt shift it so i guessed then it wasnt salt. it doesnt wipe off at all.

    Matron, its not that, have that on my garden walls and its just like powder it rubs off. plus its my back garden so not as much traffic as front

    No, it will be still under sealer. The right process is to remove sealer with xylene and start over. What i suggest you could try is powerwash the surface and let it dry thoroughly. Then seal it. Might work.
