What polymeric sand is and how can it be removed if needed

Since Home and Country USA is the top distributor of one of the best polymeric sand brands on the market, we get tons of great questions about what polymeric sand is and how to use it. Below we have listed a few of the top questions we get, but be sure to let us know through the chat box in the lower left of this page if you have any questions on the leading polymeric sand brand that we sell: Rhino Polymeric Sand

What is polymeric sand?

Also known as paver sand, hardscape sand, or even referred to as jointing sand, polymeric sand is a sand and polymer mix material that is typically used to fill the spaces around paver stones, tile, and even natural stone. This material becomes a solid binding, long-lasting filler that fills and adheres to the paver stones by simply adding water.  

How do I best remove old polymeric sand from a paver surface?

Use a hot water pressure washer set at approximately 180 degrees F or higher. The polymers will be reactivated by the heat and allow you to remove the sand from the joints. If you are removing the sand from a small section of the paver surface, use a container of boiling water poured over the area.

Can I install paver sand over regular sand in the joints?

This way of installation is not recommended. This does not allow a proper seal from the base of the paver joints to the 1/8" section towards the top of the paver. Water can seep between the joints and freeze causing the paver sand to crack.

Why is there mold and mildew growing out of my paver sand joints?

Mold and mildew are caused by underlying moisture issues. Paver sand does not prevent mold or mildew. The area of mold or mildew may be treated with a diluted pool algaecide several times per year to treat the issue on the surface.

What is the best application for Rhino Paver Sand?

Rhino Polymeric Sand is meant to be used on joints up to 2" wide. When applying the paver sand, make sure to leave a gap of 1/8" from the surface of the pavers. This allows the sand to stay protected from being walked on or driven on.

Will rain adversely affect polymeric sand application?

There can't be any rain in the forecast within 1 hour after installation on a drainage base and 24 hours for a non-drainage base.

Is it okay if there is a little moisture on top of the pavers before applying the sand?

No, polymeric sand should only be applied on completely dry surfaces.

What is the best watering technique to activate the polymers?

Working in sections up to 200 sq. ft, water the section for a total of 2 minutes.

Do not allow the section to dry during the 2-minute watering.

  1. First, use the "Mist" Setting or a similar light setting. Mist the area until the surface is wet.
  2. Follow this by adding a more substantial flow from a "Shower" setting.
  3. Finally, lower the water pressure to a lighter shower setting to allow more water over the area. Repeat the shower two times over the section.

Will polymeric sand prevent weeds?

In most cases, yes. Polymeric sand will help keep weeds from pushing through your patio. However, polymeric sand must be reapplied more often to maintain this barrier in areas that may hold water or puddles.

Can a patio be sealed after polymeric sand has been applied?

Once the Polymeric sand has cured for at least 28 days, you can clean and seal over the top of the project.
