Air Cured Resin Joint Sand
Installing joint sand on paver projects is crucial for both the structural longevity and lasting aesthetics of the installation. All joint sand fills the gaps between concrete pavers to lock them together, creating a rigid yet flexible surface. It evenly distributes weight, stops pavers from shifting, prevents weed growth and keeps out insects.
Today though, we're tip-toeing into air-cured, resin paver joint sands.
If you’ve been installing pavers for a while, you already know joint sand can make or break a job. It’s the last stage of the project and often the final step before you collect your check.
With polymeric sand, installers must keep a close eye on the weather, temperature, and even ground moisture levels that may keep your concrete pavers too moist on a shady day.
That’s where air-cured resin sands have been gaining traction. From our side of the counter at Christensen’s, we’re seeing more contractors make the switch simply because it takes a lot of the guesswork out of the process. Site prep and scheduling are more straight-forward. Yes, it’s initially more expensive than traditional polymeric. But it’s also more forgiving and less weather-dependent. With resin sand, you’re not racing the clock or watching the weather the same way you are with polymeric. There’s also no chance of polyhaze showing up after the pavers have dried and your crew has left the site.
The big win we keep hearing about is workflow. You can pack up larger equipment, clean your site, and move right into sanding the same day. No scheduling a return trip on a dry day just to finish joints! For companies juggling multiple jobs, this is real time-saver. As the saying goes “Time Is Money”
The installation is straightforward.
- Clean the compacted pavers surface, leaving it slightly damp (not flooded)
- Sweep or squeegee the sand into the joints with the help of a garden hose.
- Sweep off the excess
- Lightly mist to settle everything in.
After that, it cures from the top down as the resin becomes exposed to air. No mixing, no polyhaze, and no stressing about a surprise rain shower rolling through right after you leave.
Gator Nitro Joint Sand (stocked at Christensen’s) brings something extra to the table with its semi-permeable setup. It firms up hard and allows water to pass through. This can help with jobs where drainage matters or where permeable specs come into play.
Gator Nitro-X Fine Joint Sand installs the same way as the original Gator Nitro, but features a finer grain, making it a better fit for tighter joints and more refined surfaces. This tighter joint surface encourages water to sheet from your paved area. This may be especially useful near pools where you may grade towards a drain channel.
At the end of the day, resin joint sand isn’t necessarily about replacing every bag of polymeric sand you use. It’s about having another tool that’s a little more foolproof when conditions aren’t perfect or timelines are tight. Resin sand may offer a smoother day on site, and fewer return trips just to deal with joints.
