Alliance Gator Nitro X Fine Joint Sand for Pavers, Natural Stone and Porcelain Tile

Why Contractors Ask for Gator Nitro X by Name

Tight joints are the hardest to fill properly, and porcelain tile joints are tighter still. Nitro X is the extra-fine grade built to flow into them and set full depth.

• Extra fine gradation. Flows into 1/8 in joints on both pavers and porcelain where coarser material bridges and leaves voids.
• Rapid Flow Technology. Alliance's name for how quickly it works down into a tight joint.
• Apply rain or shine. Air cure, so rain delays setting rather than ruining the work.
• Extra strength top to bottom. 7 day compressive strength of 926 to 1,470 psi depending on color, well above the standard Nitro.
• Extra low permeability at 0.17 to 0.24 gal/min/sq ft, a much tighter joint than the standard Nitro.
• Five colors and part of the seven-piece Gator Tile System for outdoor porcelain.

Coverage is per 27.5 lb pail. Taupe and Vanilla go furthest, Black the least. Call or text (856) 418-4895 and we will size it against your tile or paver dimensions.

Where Gator Nitro X Works

Alliance rates Nitro X for drainage-base installations on:

• Patios, pool areas and walkways
• Residential driveways with light vehicular use
• Traditional drainage, permeable and hybrid bases

How to Install Gator Nitro X

The full step by step guide is in the official documentation below. Here is the shape of the job:

1. Wet the area to be jointed. More water if the surface is dry or hot — a dry surface is what causes staining.
2. Spread one third of the pail over the surface, soak it thoroughly and work it with a squeegee or hard-bristle broom, pushing diagonally into the joints.
3. Fill and rinse. Bring the joints to 1/8 in below the top surface or chamfer, shower the excess off, and repeat until the whole area is done.

Nitro X vs Nitro: Which Joint Sand Do I Need?

Same air-cure chemistry, different gradation. The choice comes down to how tight your joints are and whether you want water moving through them.

• Nitro X — extra fine, joints from 1/8 in on pavers, low permeability 0.17 to 0.24 gal/min/sq ft, higher strength, 27.5 lb pail, five colors.
• Nitro — standard gradation, pavers from 3/16 in, high permeability 0.7 to 2.3 gal/min/sq ft, 40 lb pail, four colors.
• Tight joints or porcelain, or you want a denser joint — Nitro X.
• Wider joints or a permeable system where you want maximum flow — standard Nitro.

Quick Answers

How small a joint can Nitro X fill?
Down to 1/8 in on pavers, stone and porcelain, which is tighter than the standard Nitro manages on pavers.

Can I install it in the rain?
Yes. It is an air-cure product, so rain delays setting rather than ruining the joint.

Do I need to wet the surface first?
Yes, and keep it wet throughout. A dry surface is what causes staining with this product.

How big is the pail?
27.5 lb (12.5 kg), smaller than the 40 lb standard Nitro pail.

Which color covers the most?
Taupe and Vanilla go furthest, Black covers the least.

Can I power wash it?
Not for at least 28 days.

Is it permeable?
Slightly, at 0.17 to 0.24 gal/min/sq ft, but far less than standard Nitro. If you need real flow through the joint, use the standard grade.
