Walls and Ceilings - excessive drywall compound

while drywalling our basement we may have forgotten
to sand the edges of the drywall and after taping and
spackling the seams are showing. How can we possibly fix the problem ...Also we probably used too much compound in other areas of the wall that may not have been moist enough and left ridges around the compound from not being sanded enough between coats. is it advisable to try and put more compound on and try to feather out the edges or to take the drywall off and start over as the ridges are quite noticeable even after extensive sanding.

Thanks

Hi alleycat52,as far as the seams showing after you sanded,just add some more joint compound to the seams that are showing and sand again.As far as to much compound on the other area,you can also add more compound to blend the ridges.I would sand the ridges out then add somemore mud to that area also,then try and sand it out.

Good Luck

You can also wet sponge it. The water in the sponge will rewet the compound enough to make it soft. Also as an added bonus the compound wil also smooth out under the sponge so that there will be less sanding.
