Frequently asked questions:

  1. Is SLUDGE a local product?
    Yes, it is. SLUDGE is a local product produced in Cape Town and exported all over the world.
  2. Why should we use SLUDGE and not any other tyre sealant?
    People have this myth that if it is local it is not good. There are some good homemade products out there and SLUDGE is one of them. If SLUDGE is good enough to be exported to Europe it must have some merits.
  3. Can you mix it with other products?
    I am sure that this is done by cyclist but I won’t recommend it.
  4. How long does it last in the tyre?
    This is a difficult question to answer. It all depends on how many punctures you had, the size of the punctures, Km cycled, temperatures and so on. I would recommend replacing the tyre sealant every three months or after about 2000Km cycled.
  5. Can you top up?
    Yes, you can but still, replace after the above mentioned period.
  6. If I want to use my bicycle and find that my wheel went flat over night, what must I do?
    Firs,t pump up your wheel and spin it around so that the liquid can recoat the inside of the wheel. If it keeps pressure it will stay hard once again. To be on the safe side just top up with SLUDGE.
  7. What about weight?
    All the top MTB cyclist use tyre sealants, that’s why he wins. SLUDGE is all over in the tyre and it would be very difficult to calculate the weight added to the bicycle. The added weight still outweighs the negatives.
  8. Quantity of Sludge Tyre Sealant required per wheel?
  9. Mountain bike, wheelbarrow, wheelchair: 100ml
  10. Motorbike, small car, golf car, trailers: 200ml
  11. Saloon car, pickup truck, 4×4 trucks: 400ml
  12. Busses and trucks: 600ml

How to Install?

To install you must remove the valve core with valve key supplied so that the tyre is completely deflated. Shake the bottle to make sure all the liquid is evenly mixed. Remove the cap and squeeze the sealant into the wheel. Replace the valve core and inflate to correct pressure. Rotate the wheel so that sealant can be evenly spread in the wheel and so reaching the hole. Tyre can stay on vehicle and does not need to be removed. This sealant will work in tubeless as well as tube tyres as long as the tube does not have a
cut. Sludge will work in any pneumatic tyre and is also suitable for wheelbarrows.
