FAQs
How often should I add more sealant?
Reapply Schwalbe Doc Blue every 2 to 7 months, or when you notice a significant loss of tire pressure.
Can I use Doc Blue in any tire?
No. It is suitable for tubes, tubular tires, and tubeless systems, but only works with tubes that have removable valve cores.
What happens if I get a large cut?
Doc Blue is designed to seal small punctures. It is not effective for large cuts or bursts, so you may need to repair or replace the tire.
How much sealant do I need?
Dosage varies based on tire width. Consult the sealant bottle for recommended amounts, typically between 30ml and 120ml.
Does Doc Blue work in cold weather?
Yes, Doc Blue continues to function in cold weather, but its effectiveness may be reduced in extremely low temperatures.
How do I store Schwalbe Doc Blue?
Store the sealant at room temperature, away from direct sunlight and extreme temperatures.
Troubleshooting
Sealant isn't sealing a puncture.
Ensure the puncture isn't too large (Doc Blue doesn't seal large cuts). Add more sealant, spin the wheel to redistribute, and inflate to the recommended pressure.
Valve is clogged.
Remove the valve core and clean it. Flush the valve stem with water. If the valve is severely clogged, replace it.
Sealant is drying out.
Check your tires for pressure loss. Reapply sealant as needed, every 2-7 months.
