Repeatedly squeezing a trigger can lead to hand and wrist fatigue, which is why powered caulking guns are becoming more popular. When they first hit the market a few years ago, powered caulking guns were reserved for commercial and industrial projects. Today, DIYers are discovering the benefit of letting the gun dispense the sealant so they can focus on creating a smooth bead. With no hand trigger, thrust ratio does not apply. Instead, dispensing pressure is regulated via a light squeeze on the finger trigger. Drips: We really have to boo Dripless Inc. for its sensationalized advertising. After loading the gun with the first tube, it started to ooze out. We feel robbed when a product doesn’t live up to its marketing. SpecificationsDespite it not having all the bells and whistles—like a puncture tool or spout cutter—it still has some avid fans. “I work in the glass and window industry every day and a decent caulking gun is a must,” wrote a buyer. “These have become my go-to guns even though the shop has much higher-end guns to choose from. We push silicone and paintable caulk all day and this gun is super smooth for the money.” So, the gun having an instant pressure releasing rod to prevent any extra pressure to the tube is called a dripless caulking gun. Functionality: If your caulk gun doesn’t deliver even distribution of sealant, you’ll have to seal things repeatedly. The Newborn 250, in this case, is free from such a disadvantage. It maintains equal pressure, hence even distribution. Its M12 REDLithium Battery lasts a whole day which will increase your working capability and the charge indicator lets you know how much time you can use the machine before the next charge. So, whenever you plan to buy a caulk gun, go for the dripless guns. They are good for smooth and efficient application of sealants.
