40 lbs. XL Polymeric Sand Titanium Gray for Paver Joints up to 4 in. wide

Thanks for your question! DOMINATOR® XL Polymeric Sand can be used in paver joints around an in-ground pool, provided the area has proper drainage and slopes at least 1/8 inch per linear foot away from the pool edge. However, it should not be used as pool mastic or in expansion joints at the coping/pool interface, and it is not intended for areas that are constantly wet or submerged. The sand is designed for recessed paver joints 1/8 inch to 4 inches wide and at least 1 inch deep. - BDC Customer Success Team

Hi Patt, Thanks for your question! We don’t publish a specific percentage for the polymer content in DOMINATOR® XL Polymeric Sand. The formula uses advanced polymer additives and our POWER FLEX Technology, but the exact formulation is proprietary. The available SDS for Titanium Gray (on our website under Resources) lists the reportable mineral components and their percentage ranges, but it does not provide a separate polymer percentage. -BDC Customer Success Team

Hi George, Apply the DOMINATOR® XL Polymeric Sand dry. Sweep the dry sand into the paver joints first, making sure the pavers and joints are completely dry. Once the joints are filled and the surface is cleaned of excess sand, apply water according to the installation instructions to activate the polymers. Do not mix the sand with water before installing it. Please ensure you follow instructions and scan the QR code on the bag for more helpful tips as well. If you need any further help, you can give us a call at 1-800-270-4050. We are here to help! --BDC Customer Success Team

DOMINATOR® XL Polymeric Sand is designed for use as a recessed jointing material between pavers, not for filling cracks in a solid concrete patio. We would recommend using a concrete crack repair product specifically designed for that application. --BDC Customer Success Team

Hi Tomm. Thanks for your question! A 40 lb bag of DOMINATOR® XL Polymeric Sand covers about 20–80 sq. ft., depending on paver size, joint width, and joint depth. With 1-1/2" wide by 1-1/2" deep joints, coverage will likely be toward the lower end of that range. To estimate more accurately, we’d need the total project square footage and the size of the pavers. Feel free to send those details and we’ll be happy to help. BDC Customer Success Team.

DOMINATOR® XL Polymeric Sand can be used with pavers installed over a concrete overlay, provided the installation has proper drainage. ICPI Tech Spec #10 recommends providing a way for excess moisture in the bedding sand to drain, such as drain holes at the lowest points of the concrete slab or drainage directed to an appropriate outlet. For this reason, we generally don't recommend on top of concrete. The area should not trap or hold water, as DOMINATOR® XL Polymeric Sand is not recommended for poorly drained, low-lying, or constantly wet areas. The joints should also be 1/8"–4" wide and at least 1" deep. If you have any further questions, you are welcome to call us at 1-800-270-4050. -BDC Customer Success Team

Thanks for your question! DOMINATOR® XL Polymeric Sand is designed for joints from 1/8" up to 4" wide and should be installed at least 1" deep for proper performance. Our Technical Data Sheet does not specify a maximum joint depth, so deeper joints are acceptable as long as the sand is installed as a recessed jointing material and the project has a proper base and drainage. If you have very deep joints, you can fill the extra with play sand as long as you leave 1 inch depth for our polymeric sand. - BDC Customer Success Team

Hello Emeline. Yes, the existing gravel/sand should be removed from the joints before installing **DOMINATOR® XL Polymeric Sand**. The product is designed to be used as a **recessed jointing material**, not as a thin cap over existing material. For proper preparation: • Remove the existing gravel/sand from between the flagstone pieces so the joints can be filled properly. • Make sure the joints are **at least 1/8 inch wide and up to 4 inches wide**, with a **minimum joint depth of 1 inch**. • The flagstone surface and sides of the joints must be **completely dry** before installation. • Make sure the area has **proper drainage** and permanent edging or a barrier to help keep the stones in place. • Do not install if rain is expected within 24 hours, and temperatures should remain above **50°F (10°C)** for at least 48 hours before and after installation. Proper joint depth and preparation are important for the sand to bond and perform as intended. Please reach out if you have any other question. We are here to assist. BDC Customer Success Team.
