Working with EchoMix Single:

Removal: Remove with a dry rag, water and brush or pressure washer.

Air Bubbles: All powder couplants will form small air bubbles after mixing if water is not de-aired. These small bubbles usually do not negatively affect the use of the couplant and will dissipate in 3-4 days. If an air bubble-free couplant is desired immediately, use hot water and allow to stand overnight; then proceed with adding the powder couplant.

The Blue Color is a visual marker to ensure uniform distribution of the corrosion inhibitor by encouraging thorough mixing.

Easy to open and easy to use single powder packet that, when mixed with water, yields 1 gallon/4 liters.
