Slows down Bloons even more.
~ BTD6 Description

Stronger Glue is the second upgrade of Path 3 for the Glue Gunner in BTD6. It slows down bloons by 75% as opposed to 50%. Because it inherits the properties of Stickier Glue, glue from this upgrade will last for up to 24 seconds.

It costs $340 on Easy, $400 on Medium, $430 on Hard, and $480 on Impoppable.


  • 0-1-2 Stronger Glue is useful for pure slowdown to normal bloons. 0-2-2 is a useful step towards combating densely clumped bloons. 0-3-2 Glue Hose can be used to slow down dense clumps of bloons, especially useful against Super Ceramics. Likewise, 0-4-2 Glue Strike and 0-5-2 Glue Storm are both useful for glueing all Ceramics on screen, with 0-5-2 Glue Storm doing especially well at both slowdown and adding bloon vulnerability.
  • 2-0-2 Stronger Glue is a decent choice against spaced stronger bloons, as the glue slows them down significantly, can soak through all layers (Glue Soak), damage bloons over time (Corrosive Glue) and lasts longer (Stickier Glue).
  • Stronger Glue is considered the superior crosspath for The Bloon Solver as 5-0-2, as Stronger Glue inherits the longer-lasting Stickier Glue properties as well as slowing down Ceramics and below much faster. Not only that, The Bloon Solver creating glue splatters renders the Glue Splatter crosspath mostly useless.



  • The 0-0-2 Stronger Glue's safety suit is pink.
  • Crosspathing a Tier-2 upgrade on top of Stronger Glue will make the left-hand side of the suit turn pink, the other as purple (Corrosive Glue) or orange (Glue Splatter).
  • Crosspathing a Tier-3 or Tier-4 upgrade on top of Stronger Glue will add a pink pattern on the suit of the Glue Gunner.
