Ryobi Makes Caulking Tasks Easier for Both Pros and DIYers

Caulking is one of those things that takes some practice to become proficient. When using tougher sealants like OSI Quad Max, a manual caulk gun just doesn’t cut it. What if there was a way to make that kind of job easier? Whether you’re completing extensive home repairs or renovations like replacing window trim, or you’re already a Pro, the Ryobi 18V Caulk and Adhesive Gun (PCL901B) aims to give you the control and power you need to get the job done. We’ll take a deeper dive to show you how your projects could benefit from this cordless tool.

Ryobi 18V Caulk Gun: The Big Deal

The PCL901B is Ryobi’s second-generation cordless 18V caulk gun. Like the first model (P310G), this one reaches up to 500 pounds of push force to discharge higher viscosity sealants. Ryobi tells us you can expect to get through over 200 tubes of caulk on a full 2.0Ah battery. That should hold true if you happen to be using an easy-flow material like Alex caulk or Dynaflex 230.

This caulk gun also features a variable speed dial to adjust the discharge rate to control the bead of caulk. On the older P310G model, the variable speed dial is on the side of the tool and features only a numberless meter-style control. The newer PCL901B caulk gun has a numbered variable speed dial that faces you while you use it, giving you more control over the rate of adhesive being dispensed.

Specific to the newer model is the rotating collar. When using a beveled opening at the nozzle, this lets you adjust the angle of the tip to more easily navigate corners.

Another new feature specific to this model is the ability to remove the carriage that houses the adhesive tube. This makes cleanup much more effortless. This tool also features anti-drip technology to further reduce mess and downtime between uses.

Additional Features

  • Rubber overmolded grip
  • Onboard puncture tool
  • Switch lock to prevent accidental startup during transport or storage

I’ve had one of these for about ten years. Super awesome for days when you’re burning through tubes of caulk or gluing down plywood.

Would love your thoughts, please comment.x
