Can you apply polymeric sand twice?
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!
Using too much water can cause the joint to over-saturate and result in polymer washout, mushy sand, and a weak bond. It can also result in excess sand spreading onto the surface of the pavers, which is both hard to remove and an eye sore.
So it can happen where the polymeric sand can break away however it's really easy to fix take some
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.
Yes. If you are tired of sand erosion, weeds and ants on your pavers, Techniseal Polymeric Jointing Sand can be used to replace old sand in your joints. Simply remove the old sand completely and apply Techniseal Jointing Sand. This can easily be done by a professional applicator.
It may take 3 - 4 proper wettings in order to make sure the sand is wet the entire depth of the joint. You can test this by taking a long nail or screwdriver and burrowing down to make sure it is wet throughout the joint. After doing so, replace the sand back into the joint.
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.
You can't pressure wash and apply polymeric sand on the same day. I should warn you that getting the stain off is a huge problem so it's best to take the time to avoid it in the first place.

Thus, the most suitable pressure for cleaning pavers is the medium range (From 1600 to 2000 PSI). For even better performance, use a hot water pressure washer at 180 ° F. The heat will reactivate the polymers in the product and allow you to strip away the sand. If it's a smaller paver area, use boiling water.
How deep should polymeric sand be?
When the sand is 1/8" below the top of the surface, it allows for the best bonding and adherence of the paver joint.
Polymeric Sand is a high-tech mix of graded sand and binder, specially formulated for the filling of narrow or wide joints when installing pavers, slabs or natural stones, or when replacing existing joints. Unlike conventional sand, it stays in place and remains stable.
This particular material exists specifically to provide a lasting bond between pavers. 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.

1. Polymeric sand hardens quickly. This can be a benefit—you don't have to worry about it creating a mess that you can't get rid of, and it makes the finishing process simple. However, you should NEVER install polymeric sand when it is raining!
