If steps 7 to 10 are not done properly, a white haze may appear on paver surface after installation. This haze will dissipate over time, or it could be removed by using Gator Clean Efflorescence Cleaner. The presence of moss, mold or mildew is caused by the particular on-site conditions, including excess moisture, shade, absence of ventilation, inadequate cleaning or maintenance, presence of soil or other organic debris left on the product after installation.

Ideal for. Helps Prevent. Color Selector. Concrete pavers, natural stone, wet cast products and clay pavers Residential and commercial use Streetscape, commercial work, steep slope, pool areas, patios, walkways, driveways and parking areas Traditional applications and overlay applications.
Quantity required depends on the shape and size of the concrete pavers as well as the width of the joints. Holes should be filled with 8 stone and covered with a 1 foot x 1 foot 30 cm x 30 cm patch of Gator Fabric GF4. Drilled holes should allow any water entering the bedding layer to freely flow out.
Polymeric sand needs to be installed on a dry surface. Check the weather. If you're using our G2 with Rapid Set Technology , this product is rain safe after only 15 minutes! Have your tools ready. Pour the sand. When emptying the bags, make sure to distribute evenly to help maintain consistency of the gradation of the product. Use a hard bristle broom to initially sweep the sand into the joints.
And then … it rains. Photo Courtesy Of Unilock. Heavy rainfall or watering is not good for a freshly finished polymeric sand job. So what happens if it rains following the installation?
Well, the future life of that installation will ultimately depend on the circumstances. Polymeric sand is a sand formula that is swept into the joints of pavers and natural stone to lock in the product, prevent weed growth and insects, and to provide the final touches of any hardscaping job.
The sand remains hard when dry and flexible when wet to allow for it to remain intact if the surface moves whether through frost cycles or traffic. It is what makes it a superior product for the filling of joints. Over many years, the formula has improved as competition in the space grew and now today we have some pretty incredible polymeric sands on the market. Still the market is not without problems, most of which come from the installation.
The installation of polymeric sand may not get the attention it deserves because it is thought of as being a simple process that can be handed off to anyone. Unfortunately, that is not the case. There is still a lot of involvement in the process and if you miss a step or gloss over the process, you will have a failure on your hands which will cost you time and money. Every manufacturer has a different formula and a different set of instructions.
Even between different products in their lineup. That is why it is so important to familiarize yourself with the product that you are used to and to follow the instructions carefully. There are universal steps to the process of installing polymeric sand, failure signs, and ways in which you can ensure that your polymeric sand installation will run smoothly.
Installing polymeric sand involves more than just sweeping and watering. It requires some more steps to ensure that you are not going to have a failure to fix well after the installation. There are a few things that should be considered from an installation perspective. The base material should be free draining. What should not be installed is stone dust or chip dust. That is because this will harden and not allow water to drain through, keeping the water below the pavers and saturating the joints, not allowing the polymeric sand to properly dry and never set.
Your surface should be free of dust and debris prior to installation, so you can take your leaf blower or broom and clear off the surface prior to your installation. Remember that if the sand requires 24 hours to set, temperatures should not drop below this temperature overnight as well. Your project should also have the edge restraint installed.
We will be compacting the sand into the joints of the installed product, so we want to make sure that there is not room for lateral movement. Having the edge restraint installed will make sure that this will not happen during the polymeric sand installation process. Failure to do this will result in the erosion of the polymeric sand and weakening its bond. When it comes to calculating how much polymeric sand you will need, you can consult with the manufacturer of the product that you are installing.
Most paver manufacturers will have this information available based on the size of the paver less joints and the thickness of the joints themselves.
A product with lots of tighter joints may yield as much as square feet per 50 pound bag, but a product with larger joints may yield as little as 50 square feet per 50 pound bag. This is important to consider especially when quoting a project. With these factors considered, we can continue on to the installation of the sand itself, as well as the equipment that would be required to install the sand. Making sure that your polymeric sand installation is successful requires that you have the right tools for the job.
