Polymeric Sand for Paver Joints up to 4 Inches on Traditional Installations, Single-Watering 50 lb Bag
Polymeric sand fills the joints between concrete pavers and natural stone for patios, driveways, walkways and pool decks. This Alliance formula accommodates traditional joints from 1/8 to 4 inches wide, making it suitable for projects that combine narrow gaps and wider stone joints.
Single watering activation and a formula designed to sweep clean simplify installation without a blower. Each 50 lb bag comes in Slate Grey, Black Diamond, Ivory or Beige, so you can coordinate the joint color with your paving.
Install only on completely dry pavers and joints above 32°F, with a minimum joint depth of 1-1/2 inches and at least a 2% slope. Overlay joints must not exceed 2 inches wide. Rain-safe timing is 15 minutes for traditional installations and 24 hours for overlays.

Frequently Asked Questions
Can this polymeric sand fill 4-inch joints on an overlay installation?
No. This polymeric sand supports joints up to 4 inches wide on traditional installations, while overlay joints are limited to 2 inches. Both require a minimum width of 1/8 inch and depth of 1-1/2 inches.
How much paving does one 50 lb bag cover?
One 50 lb bag covers 65–85 sq ft for narrow joints or 22–42 sq ft for wide joints on 2-3/8-inch-tall pavers. Black Diamond covers 58–76 sq ft or 20–38 sq ft respectively. Narrow means 1/8–3/8 inch joints; wide means 3/4–1-1/4 inch joints. Joint depth and paver height also affect the amount needed.
How long does this polymeric sand need before rain?
This polymeric sand is rain safe after 15 minutes on traditional installations and 24 hours on overlays. Apply it to completely dry pavers and joints above 32°F.
Can I use this sand around a swimming pool?
Yes, this polymeric sand is suitable for paver pool decks. Pool coping joints must be mortared rather than filled with sand, and the paved surface needs at least a 2% slope for runoff.
What preparation is needed before activating the sand?
Sweep and compact this polymeric sand fully into dry joints, then remove every loose grain from the paver faces before watering. Activate on a shower setting for at least 30 seconds per 30 sq ft, saturating the joints without flooding them. Do not sweep it over asphalt; test clay pavers on a dry surface first.
