How To Seal Pavers With Polymeric Sand. Polymeric sand is a dry mixture of calibrated sands, polymers, binders and dedicated controlling agents technically designed to bind together in horizontal pavement joints. Easier to install and more durable than traditional hardscape aggregate, they also prevent weed growth and insect infestations. So we’re going to steam clean it. Polymeric sand often comes into play at the end of a landscape paving project, including projects involving concrete pavers, brick pavers, and stone pavers.

Contractor swears he must come back and seal the pavers and that is why pavers look dull. The combination of the materials that make up polymeric sand creates an incredible binding agent that locks the pavers together. Step 6 repeat the sand application and tamping up to three times, being sure on the last application to fill every minuscule crack and crevice in between the pavers. Patios and walkways made from pavers that have been laid in sand are simple to maintain. Its high polymer content and its unique composition will generate optimum results. Sealing new pavers can also help keep mold away.

The success of this step depends in large part on the pavers being installed properly on firm, flat layers of gravel.

Here is a picture of pavers that have been sealed vs pavers that have not. The sand helps to secure the pavers into a uniform and durable surface. For those of you who don’t know, polymeric sand is a coarse, dried sand that has had polymers added to it that when activated with water, harden up and seal off paver joints (the seams between each paver). The material is useful to fill in the gaps and seams between the concrete pavers, jigsaw stones or bricks laid to form the walkway or patio. The contractor used polymeric sand. Paver joints need a mixture of coarse and medium sand to allow complete filling of the joint.
