Polymeric Sand

Polymeric sand is a finely graded jointing sand blended with binders that activate when wetted. Once set, it forms a firm yet flexible joint that locks block paving and paving slabs in place, resists washout from rain and helps discourage weed growth and insect activity. It offers a tidier, longer lasting alternative to standard kiln dried sand, particularly on patios, paths and driveways where loose sand is easily lost.

We stock Nexus PolySweep Polymeric Sand, a popular choice for block paving and narrow joints. For the best results, the paving should be clean and completely dry before application. The sand is brushed into the joints until they are fully filled, compacted, and any excess swept carefully from the surface before activating it with a fine mist of water. Any product left on the face of the paving can bond to it, so take care to remove all surplus before wetting. Weather conditions matter too, so avoid application when rain is forecast before the sand has had time to set. Please read the product description carefully for joint width and depth guidance, coverage and curing times. Wear gloves and a dust mask when handling dry polymeric sand, and test on a small area first if you are working on porous or light coloured paving.
