Slip resistance is the spec, not an afterthought
On guest-walked surfaces the finish decision is a risk decision. My walkway default is a natural-look matte product that protects the pavers without adding a slick film, because a glossy walkway in a Florida afternoon storm is a claim waiting to happen. Where an owner wants enhancement for a covered or low-water path, that is a deliberate, documented choice.
Joints get equal attention. Washing out the old sand and re-sanding with correct spec sand keeps pavers from rocking and rising into trip hazards, and the stabilizing seal locks the work in place through the rainy season. Before and after photos document the condition either way, which your risk file will appreciate.
Straight answers
The questions I actually get, answered the way I answer them on the phone.
Can walkways stay open during sealing?
Paths get sectioned so an open route always exists, and cure windows are scheduled for the property's quietest hours. Full closures are rare and announced.
Our walkway pavers are already lifting. Seal or repair first?
Repair first where pavers have genuinely heaved; sealing locks in whatever exists. On the site walk I will flag which areas need resetting before the wash-sand-seal cycle makes sense. Honest sequencing beats a pretty photo over a bad base.
