A minimum of 24 hours drying time is required prior to allowing significant foot traffic and 48 hours for vehicular traffic on the paver surface. Polymeric sands are designed to soften and re-heal.
How do you store polymeric sand?
If you have leftover polymeric sand from your project (and it’s still in the bags), the bags can stored in a dry location for future use. Properly stored and kept in a low humidity environment in its original unopened bags, our polymeric sands should be usable for up to five years.
Does polymeric sand harden over time?
particles is another step that is often rushed through or skipped to save time. However, once water is applied, any remaining polymeric sand particles will harden and remain on the surface resulting in an unhappy customer.

Can you apply polymeric sand twice?
First, you run the danger of disturbing your base/shifting your pavers. Secondly, you will have to wait a day while the surface dries before you can reapply your new sand. Remember polymeric sand and moisture don’t mix until after it’s in the joints!
Why is my polymeric sand not hardening?
Polymeric sand cures by drying. And in order to fully set, it needs to dry out completely. If your polymeric sand didn’t harden up, it’s pretty much guaranteed there’s a moisture issue. If the joints remain wet after the installation, they will remain soft until they dry.
How long before it can rain on polymeric sand?
Most poly sands are considered “rain proof” after one hour, but I wouldn’t bet the bank on that. You really want at least 24 hours of warm, dry air to ensure that the poly sand completely sets. Sustained dampness prior to setting may damage the poly sand to the point it will never set.
How do you activate polymeric sand?
Quote from the video:
Quote from Youtube video: Water i always want to be careful. If there's any foaming any of that suds that starts to appear in those joints i want to back off the water i don't want to wash the polymers out of the joints.
How long after polymeric sand can you seal pavers?
24 – 48 hours
If us- ing polymeric sand, you can install it after the sealer application has properly cured for 24 – 48 hours. If polymeric sand is installed prior to sealing, be sure surface is dry for 24 hours before applying sealer.

Do you need to seal polymeric sand?
Without any kind of sealer, the sand in your joints will blow and wash away. Fortunately, if you use one of Seal \’n Lock’s paver sealers, you won’t have to worry one bit about purchasing or installing polymer sand.
Why does polymeric sand fail?
Epic Fail #1: Too much or too little watering.
A polymeric sand installation requires the use of a controlled and methodical watering technique. Using too much water can cause the sand to wash out of the joints. On the contrary, using too little can result in the product not setting up properly.
Do I have to remove old polymeric sand?
But unlike normal sand, the compound hardens very quickly when you expose it to moisture or water. Thus, you must remove polymeric sand from pavers’ surface before you finish your project. Still, the polymeric sand usage in paving projects is probably one of the best choices when it comes to sand types for joints.
Can you touch up polymeric sand?
Quote from the video:
Quote from Youtube video: So it can happen where the polymeric sand can break away however it's really easy to fix take some sand and a little cup. Sprinkle it into the joint. And then just brush away any excess.

How often should you apply polymeric sand to pavers?
If you chose polymeric sand, even if exposed to the same circumstances as regular sand, it may last up to ten years (or more). Note that to increase durability, you can apply a sealer over pavers in both cases (polymeric and regular sand). This substance acts by creating a protective layer on the flooring surface.
How big a gap can polymeric sand fill?
How Big a Gap Can Polymeric Sand Fill? Polymeric sand works best to fill gaps between 1/4 inch and 1.5 inches wide. Wider joints will require more time to harden. Some pavers are designed to fit together like puzzle pieces – if the gap is too small, polymeric sand won’t help.
When should you not use polymeric sand?
#6 – Too Narrow or Too Wide Joints
The sand is simply pushed out of the joints. This is why we don’t recommend using polymeric sand on extremely narrow joints. Similarly, too-wide joints can lead to washout, because they allow too much water flow during the activation process.
Will polymeric sand stop pavers from moving?
Polymeric sand helps to hold the pavers in place and prevents them from shifting or moving.
