Can I seal only the driveway and not the walkway?

Seal one paver surface and leave the one beside it alone, and the place to look is the edge where the two meet.

ICPI's Tech Spec 5 says most sealers darken the paver surface and enhance its color. That change stops where the sealer stops, at the line where a sealed driveway meets an unsealed walkway, a step or a strip of pavers left for later. How much darker a given sealer reads, and what a wet-look finish adds, is answered on how much darker sealing makes pavers.

ICPI describes the darkening as a change in appearance, and nothing in its documents treats the edge as a fault. Whether a darker driveway beside a lighter walkway suits the curb appeal of the property is the owner's call.

The paver documents a driveway and a walkway both answer to never ask for a matched set.

ICPI's construction guide treats sealers as optional, which leaves a driveway and a walkway free to be decided one at a time. Whether a given surface needs sealing at all is its own question, answered on whether pavers need to be sealed at all.

Where ICPI does single out a surface, it points at the kind that gets driven and parked on: Tech Spec 5 lists driveways, other areas subject to stains, and places where oil drippings are not wanted among where sealers are useful, and Tech Spec 6 adds barbeques. That list names the surface cars are driven and parked on; it does not name a walkway. A newly cleaned pavement, ICPI adds, is “an opportune time” to seal or stabilize, whichever surface that cleaning covered. What a sealer does on a cleaned paver surface is set out in the sealing section of the paver cleaning page.

An association's declaration is a separate document again, and it, not a paver document, sets any appearance standard that applies; that question is covered on whether a wet-look sealer needs association approval.

The paver surfaces 239 Exteriors names are driveways, patios, walkways and outdoor living spaces.

The estimate form asks for the Service needed, with paver cleaning among the choices, and has a Project details field. That field is where a property owner writes which surfaces the request covers: a driveway to be sealed and a walkway left as it is, or the other way around. Estimates are free, and the paver work 239 Exteriors names is described in the pavers section of what 239 Exteriors cleans.

A surface skipped for now is not the same as a surface with a problem. Sunken or loose pavers are a different question from an unsealed one, and whether sealing does anything about either is answered on whether sealing fixes sunken pavers.
