Estimation Guide for Chinking
|Lineal feet per full gallon (231 cu. in.)||
Width of Joint
|Depth of Joint||1/4"||154||77||51||39||31||25||22||19|
|You may calculate gallonage needed by finding the feet per gallon and dividing your lineal feet by that number.
Keep in mind that the depth is an average depth across the joint. We tend to think of the depth in the middle of the joint where it is actually the thinnest. If your estimations are generally short, check to see that you use average joint depth.
