Experts recommend starting with small areas first. Say, 10 feet by 10 feet. Use the “shower” setting on a hose nozzle. The goal is to saturate the joint filled with sand. Spray a joint and observe.

Styles & Trends

Before even thinking of laying paving slabs, you need to prepare your patio area. If you’re upgrading paving slabs that are already in place, dig these up before beginning. Dig a depth of around 150mm across the whole area, making sure the soil is evenly compacted. Then tip in the sub-base, raking it into a consistent depth of 100mm. Make sure it’s smooth, flat and firm. When using a dry mix you need to make sure that your patio slabs are completely dry and that there is no rain forecast. This will help make sure that dry mix doesn’t form into clumps and doesn’t stain your slabs, giving decent looking and effective pointing. When your patio or driveway was poured, chances are that the professionals installed a joint expansion system. Many times, an asphalt-saturated fiberboard or felt was used. But that material decomposes. If you are using a traditional dry mix you will get a smoother finish if you use a dry building sand or a kiln-dried jointing sand (which is a fine dry sand). Sharp sand is coarser than both and won’t give such a smooth finish.

Once the polymeric sand has set up, heavy rain won’t hurt it. But if you have just finished applying polymeric sand and it hasn’t yet set up – like in the first 24 to 48 hours – then you’ll need to protect your patio from a downpour. Use a tarp or plastic sheet.The jointing compound wants a 3mm gap (no problem if much larger like 10mm) and in their example they want to highlight an inch depth, despite being a new install, they will still want you to go an inch down on your old patio – this is pretty much the standard and whilst it never guarantees you hold weeds and insects at bay, you give yourself the best possible chance! This is very much the same process as pointing a patio, but you will need to do a little prep beforehand. First you will need to remove the old pointing with a hammer and a bolster or plugging chisel.
