I'm thinking of resealing my pool pavers and pool coping. My question is will resealing over old sealant leave unsightly coverage on my pavers or should I strip away any old sealant first, then reseal, if possible?
 
If you seal over old sealant, what are you really sealing? The adhesion of the new sealant will only be as good as that of the old sealant if you put it on top of it.

Not stripping down to a clean surface is the cheap, lazy way of doing a job.
