TOP-UP sand joints & STOP WEEDS.
Unlike kiln dried joint sand, Kingfisher Block Fill is a moisture curing grout which will not wash out and also inhibits weed growth. Easy brush-in application to joints of 5mm or less for clean, dry block filled paving and patios.
Well worth it
Can seem expensive but 15kg goes a long way at 25mm deep and saves you from the usual 'pressure wash and re sand cycle'. Can leave a slight cement like film on the paving if you don't get the sprinkling of water just right but if you follow the instructions it turns into a grout and runs into the joints, just don't over water so it runs off the paving. A tip, on first opening the tub make the effort to mix the materials if you can see they have separated. All in all well worth it.
