FAQ's

  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.
