It can be weathered down again.

Sandstone in most cases is fairly loosely fixed together and usually the individual grains are rounded. This means rain and wind can easily detach them from the rock and carry them down wind/stream to form a sediment elsewhere

Weathering is the important process, which breaks down the consolidated sediments, i.e. sandstone in this case, either mechanically (wind, water or ice) or chemically (hydration/dehydration; solution/precipitation; etc.) or biologically (root penetration and bioturbation, etc).

Sandstone can be brought to the surface due to erosion and uplift. Then it can be weathered and eroded when eposed, leading to the formation of sediment.
