Blue Max on a cistern

Having a problem with leaks in your water tanks & cisterns?

You’re in luck! Ames Research has the solution on how you can fix your water tanks and fix your cisterns. To begin, repeat the concrete walls and foundations instructions…

Concrete Walls and Foundations instructions step 1

1. The surface must be clean, dry, and free of loose materials. Fill all joints or cracks wider than 1/8 inch with Ames Blue Max Trowel Grade.

2. It is important to seam tape all joints and cracks with Ames Peel & Stick Seam Tape (PS250, PS450, or PS650) to avoid future cracking and leaking.

3. Ames Blue Max may be brushed, rolled or sprayed. We recommend a minimum of two to three gallons per 100 square feet as needed. Apply in multiple coats for water containment. The application must be applied in a continuous, unbroken seal with a minimum dry thickness of no less than 30-70 mils ( the thickness of a dime to a quarter). Allow to completely cure before filling. Ames Blue Max can continue to cure for up to two weeks.

Weather & Drying Guidelines

Ames Blue Max is best applied between 50* to 90*F (10* to 32*C ) on warm dry surfaces. Be sure humidity is under 50% and that the dew point and temperature have a good spread. Check the weather and remember the rules: Apply when the streets are dry, the sun is in the sky, and no inclement weather is forecast for at least 48 hours. Ames Blue Max goes on a light blue color and dries to a darker blue. Make sure Ames Blue Max is completely dark blue before proceeding with the next coat. Ames Blue Max begins to dry in 30 minutes to two hours depending on the thickness of application and weather. It is recommended to allow 4-12 hours of drying in the summer months between coats. In humid locations, additional drying time may be required. Ames Blue Max continues to cure for up to two weeks. Low temperatures, high humidity, evening and morning dew will require increased drying/curing time. A slight tack is normal after drying.
