For example, 1 Tablespoon = 1 gallon. You would put 10 Tablespoons of product in the sprayer, fill the sprayer to the 10 gallon line and mix well before starting to spray. If you have any other questions about this sprayer that we can help with, please give our technical Customer Service Team a call at 800-950-4458 and they will be happy to assist you. Thank you for your question and for your interest in Chapin Sprayers. **Q: what is the highest level of concentration? I would like to mix a 10-to1 ratio of water to bleach.** A: You might be better off with a sprayer that has a mixing dial. You cannot vary the mix on this sprayer. **Q: So, if I'm using a product that calls for a ratio of 3 oz./gal., how much product do I put in this thing? I am math challenged, obviously :-(** A: A gallon is 128 ounces. A quart is 32 ounces. There are 4 quarts in a gallon. If you are saying your bottle sprayer is 32 ounces then I would presume you would need to divide the 3 oz by 4 which is 0.75 ounces. If you have a shot glass most shot glasses are Close to 1 ounce. So you would need to do a shot glass and fill it 3/4 of the way up with your product per usage. At least that is how I calculate it and what I would do. **Q: Can this be used with granular fertilizer?** A: Hi. The Chapin G390: “Lawn Hose End Sprayer for Fertilizer” can be used with liquid or powder products. When using powders, be sure to mix the solution thoroughly before spraying to avoid clogging.
