Golf Practice Putting Surface Our Premium Plus Multi-Play sports grass is also a really superb surface for golf putting practice. Once kiln dried sand is added into the grass after it has been laid, it not only creates a very effective flat surface, it generates a slightly lower ball speed when putting, ideal for those used to their putting on UK greens. We recommend adding between 7 to 14 kilos per m2 of kiln-dried sand for golf putting practice. The more sand added slows the ball speed.
