honed black absolute granite Description

My contractor sealed my black honed Granite (http://tanbrown.org) with 511 porous plus 
sealer, but it left a residue.  Is it possible to try a color 
enhancing sealant, after I just sealed it with 511 or do I need to 
get some product to take the first sealant off, in order to use a 
color enhancer?

Thank you,
