How It Works

Liquid Hammer Usage Instructions


Wet/Rinse the Vehicle.

Vehicle Surface temperatures should be cooled and rinsed free of any loose dust, cement, or road film. Concrete build-up should be saturated with water. A pre-rinse is not absolutely required, but Liquid Hammer will perform better when applied to a cool, wet, and/or saturated surface. Application/dwell time in a shaded area will also increase the efficiency of Liquid Hammer.

Foam the Vehicle.

Hold the nozzle 12-18" from the surface of the vehicle and apply a thin to moderate coating of liquid Hammer foam to all areas being cleaned. It is not necessary to "pile" the foam on. Work your way from the areas with heavy build-up to light build-up to allow maximum dwell on the heavy areas. When cleaning a mixer drum, charge the drum at high RPM to allow for faster application.

Dwell for 15-30 Minutes.

Liquid Hammer takes at least 10-15 minutes to react with the hardened concrete and is most effective when allowed to dwell for a half hour or more. For maximum dwell time, foam liquid hammer on dirty vehicles and park them to soak overnight. Cabs should generally be washed and rinsed in the same day since they do not typically have heavy build-up like the "business" end of the mixer.

Wet, Brush and Rinse.

Brushing the vehicle during the rinse cycle is very important to help remove dissolved concrete and to prevent calcium carbonate (white) films. After the product has been allowed to dwell for 30 minutes or more, re-wet the truck, then bush the truck with a proper truck wash brush and rinse thoroughly to remove all dissolved material.
