How To Choose The Right Polymeric Sand?

Consider these factors when choosing reliable polymeric sand.

  1. Quality: Good-quality polymeric sands prevent weed growth and damages caused by insects. They are made of finer sand and can fill the smallest and tightest joints.
  2. Drying time: Polymeric sand usually takes 24 to 48 hours of drying time for non-drainage applications. Some polymer sands employ Rapid Set technology, which allows quick setting in 15 minutes for drainage applications.
  3. Resistance: Superior-quality polymeric sands are resistant to erosion from wind and freeze-thaw and are also rain-safe. These sands are also haze-free, dust-free, and blower-free.
  4. Application: Polymeric sand can be used for commercial and residential applications. It is also suitable for overlay, no-overlay, and false joint pavers. Consider the application before choosing one.
  5. Color: Polymeric sand comes in a wide color range, including beige, gray, and slate gray. Pick a color that blends perfectly with the color of the pavers or stones.

Frequently Asked Questions

1. Is there an alternative to polymeric sand?

Yes, cement or natural sand are good alternatives to polymeric sand.

2. When should I not use polymeric sand?

You should refrain from using polymeric sand when it rains or if rain is forecasted shortly after application. This is because rain can activate the polymers and harden the sand even before the sand is installed.

3. Can I pressure-wash polymeric sand?

Pressure-washing polymeric sand can remove the sand by softening the binders. However, for tough areas, you may need mechanical removal methods.

4. Should I seal my pavers before installing polymeric sand?

It would be best to seal the pavers after installing polymeric sand. Modern methods require only a 30-day delay before sealing.

5. Can I put new polymeric sand over old polymeric sand?

It is not recommended to apply new polymeric sand over the old one. Remove the old polymeric sand and clean the area before installing the new polymeric sand.
