The amount of water needed for a premix bag of concrete typically depends on the specific brand and type of concrete mix you’re using. However, a common guideline, this will require about 6 pt to 9 pt (3 to 4.5 quarts, or 3/4 to 1-1/8 gallons, or 2.82 L to 4.26 L) of water per 80 lb bag of concrete.

There are concrete bags from brands like Quikrete or Sakrete that weigh around 90 pounds (90lb), 80 pounds (80lb), 60 pounds (60lb), 50 pounds (50lb), and 40 pounds (40lb). A premix bag of concrete is blended mix of Portland cement, sand and gravel with some additives.

How much water do you mix with a bag of concrete depends on weight of a concrete bag. Typically, a 60 lb bag of concrete should require about 1/2 to 3/4 gallons (4 to 7 pints) of water; but start with about 4 pints and mix; then add the rest 3 pints if you don’t like the consistency.

Empty the concrete bag into a mortar tub or wheelbarrow and form a depression in the middle of the mix. Typically, for each 80 lb bag of concrete mix, you will need about 6 pt to 9 pt (3 to 4.5 quarts, or 3/4 to 1-1/8 gallons, or 2.82 L to 4.26 L) of clean water, but start with about 6 pints and mix; then add the rest 3 pints if you don’t like the consistency.
