We recommend a joint height of min. 4 cm when filling your joints to ensure that the roots of the seed do not have enough time to find nourishment, as it will dry out before then.

Problems DANSAND® NO GROW™ Joint Filling Sand has been developed to prevent weeds, but it is not a weed killer. The product consists of washed and oven-dried silica sand, to which we have added a natural mineral. The mineral increases the pH-value and the ZAR value of the silica sand, creating an “unfriendly” environment that does not provide nourishment for weed plants. Hence, a weed seed that finds its way to your joint and tries to set roots here, will dry out after a short time.The content of the bag should be mixed before sweeping the material into the joints otherwise the binders will not be mixed with the silica sand. Maybe some of your joints have hardened and some of them have not? If so, the binders have probably not been mixed with the silica sand.

There’s also the benefit of Dansand No Grow’s natural weed-preventing abilities to account for, meaning you won’t need to fork out on a coat of patio sealer to fully protect your paving from unwanted organic pests and moss growth.
