In this video, we learn how to caulk a crack in your home. First, take your favorite type of non-silicon caulking tube. Then, take a knife and cut the tip off of the caulking tube at a 45 degree angle. Then, take a coat hanger and stick in the tip of the tube to break the seal that's inside. Next, take an open frame gun with a spring release lever and install the tube into it. Now position the gun in a 45 degree angle to the crack and slide it along the length of the crack. Wipe the tip of the caulking tool with a rag and wipe your finger along the crack you just caulked. That's all there is to caulking a crack!
