When the floor is dry, put the sealer in a large paint tray. Use a brush to cut in the perimeter and then roll the rest with a mediumnap paint roller, equipped with a long handle.

I just used Thomson's concrete sealer. This is a decent sealer for an indoor garage, the sales guy at my local Do-it-yourself store said it was cheap, this is true for external sealing. There's a costlier product by EPOXY. I stayed away from it as it was $60 for the kit. It just cost me under $30 for Thomson's sealer, a roller, paintbrush, tray, degreaser, a pack of 10 gloves. It was an afternoon well spent and a I now have a smoother garage surface.
