Beesley and Fyldes,don`t know if they are nationwide though,i have put a bit down on last 3 jobs,just in the corner when i started sanding and told custy to press it with finger in an hour or so and then press a bit i haven`t put it on,every one told me to do the hole job,it costs roughly £6 a litre and i charge £12 a litre laid,i would do it for cost to be honest as i know sand s not going anywere when it rains,no weeds or ants for a good while either,keep it to ourselves though,ha ha
