Can you over water polymeric sand?

When watering in the Poly Sand, remember Goldilocks - "This is just right." Don't use too much or too little water. The amount of water you use is a critical element to an installation. Using too much water can cause the joint to over-saturate and result in polymer washout, mushy sand, and a weak bond.

What happens if you overwater polymeric sand?

A danger of using too much water too quick creates the possibility of washing away the polymers. Too little water used in the installation process could leave you with a fragile joint. If the joint is not properly watered to at least 2/3's depth, a hardened crust may form at the top of the joint.

How many times do you wet polymeric sand?

Generally speaking, you'll want to perform three rounds of watering. The initial showering should be done at a height of about 4 ft. Wait no more than three to four minutes before performing the second round of showering at a height of about 2 ft.

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.

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!

Can you add another layer of polymeric sand?

It is not ideal to add a thin layer of polymeric sand on top of what's already there for many reasons: the original sand can be old, of unknown condition, and/or dirty. The best approach would be to remove at least 1" of the jointing material and follow the steps for a new polymeric sand installation.
