How to apply Chinking

Make sure that you have read our measurement guide to make sure that you have the right nozzle size and thickness. Start by lubricating your tools with a silicone type spray. Then put nozzle end of the gun into the bucket of chinking and pull the activator rod. This will suck the chinking into your gun. When applying your chinking for log homes, you will want to check with the manufacturer for the recommended thickness to ensure proper application and avoid the need for repair.

On average you want your thickness to be between 3/16" and 1/4" if it is to thick it will flake and if it is to thin it will break. Once you apply your chinking, use a foam brush or spatula to go over your chinking with smooth strokes in one direction, ensuring to check the weather conditions as they can impact drying time. It is important to use plenty of water or a release agent. If you use a release agent, then be careful not to use too much as it will affect your chinking. Make sure that the chinking is adhering to the top and bottom really well with a strong adhesive.
