Nexus PolySweep Polymeric Sand – 20kg

1. Why is PolySweep suited to block paving, over other products? PolySweep is specially designed for block paving. It bonds perfectly with the narrow, uniform joints found in block paving, ensuring a durable, long-lasting finish.
2. What is the difference between PolySweep and other products on the market? PolySweep stands out because of its superior durability and resistance to cracking. It also has a strong bond, making it less prone to washing out.
3. How long does PolySweep take to cure? PolySweep typically cures within 24–48 hours, depending on the weather. Once cured, it forms a strong, durable joint.
4. Do I have to remove all the weeds before application? Yes, it’s important to remove all weeds and debris before applying PolySweep. This ensures the joints bond properly and prevents weeds from regrowing.
5. Do I have to use a whacker plate during install? Using a whacker plate is recommended for the best results, as it helps compact the joints and ensures a strong bond.
6. I don’t have a leaf blower, can I go without one? A leaf blower is helpful for removing excess product from the paving surface, but it’s not essential. A soft brush can also do the trick, but take care not to dislodge the jointing material.
7. How long can it not be rained on, after application? PolySweep needs to stay dry for at least 24 hours after application. If rain is forecast, it’s best to cover the area with a tarpaulin to protect it.
8. Why should the bedding mortar be permeable? PolySweep cures when it dries out, because of this, water/rain must have a route of escape.  Furthermore, a permeable sub-base allows water collecting in the joints to drain freely, stopping it from building up within the joints and become stagnant – this stagnant water overtime can soften the binder and encourage algae growth.
9. When you say permeable bedding mix, what does this mean? A 5:1 ratio of sand and cement or above is classed as permeable.  Or using a specific permeable bedding mortar is also acceptable.

PLEASE BE AWARE THAT COLDER TEMPERATURES WILL INCREASE BOTH CURING TIMES & THE PROTECTION TIME DURING WET WEATHER!
