E-SAFE: Cause and Effect PDF Print E-mail

E-SAFE Liquid Concrete RemoverE-SAFE LIQUID CONCRETE REMOVER is a maintenance product and should be applied on a routine and scheduled basis, regardless of the operators time limits to rinse or remove concrete. A scheduled application of E-SAFE LIQUID CONCRETE REMOVER will ensure truck cleanliness at the time of concrete removal. Typically fleet managers opt to foam or apply product on a Friday night and brush, rinse or power wash Monday morning.

Washing frequency should not be discouraged; as a little product applied more often provides better results. Product costs can be controlled through our positive displacement foaming systems. The foaming system allows full control over the amount of product being applied per wash.

E-SAFE 5BMore isn’t necessarily better! Water or moisture is required to keep the product active and penetrating. E-SAFE LIQUID CONCRETE REMOVER is typically applied through our positive displacement applicator at a 5to1 ratio with water. In a laboratory environment reaction with concrete has been confirmed at a 120 to 1 ratio.

A light rain, moisture from the night air or a light misting of water in conjunction with product residence time offers the best solution to removing heavy deposits.

E-SAFE 5AIn the spring of 2004 a fleet manger (powder trailers) opted to apply E-SAFE LIQUID CONCRETE REMOVER on a weekly basis without attempting to remove the deposits of clinker. A wet spring with frequent rainstorms self cleaned the trailers.

Chalking Effect

This is a white powder or white surface layer that will become apparent as the surface of the equipment dries after being cleaned with E-SAFE LIQUID CONCRETE REMOVER. The white surface layer may not be uniform or cover the entire surface of the equipment. In extreme cases the truck may look visually worse after it’s cleaned. The caulking effect will not occur on equipment that has had limited exposure to Hydrochloric acid.

Why is this occuring? E-SAFE LIQUID CONCRETE REMOVER reacts immediately with concrete and clings tenaciously to the surface of the equipment, even after the encrusted layers of concrete have been removed from the equipment. The residual effect of E-SAFE LIQUID CONCRETE REMOVER continues to attach itself to the remaining calcium deposits and will lift them to the surface. The calcium deposits are contained in the metal or painted surfaces that have been etched by years of repeated Hydrochloric acid use.

The Remedy! Apply a light misting of water to reactivate E-SAFE LIQUID CONCRETE REMOVER and remove by a light bushing or high volume rinse. In extreme cases multiple applications of E-SAFE LIQUID CONCRETE REMOVER may be required or wash frequencies increased until such time as the pores of the paint or metal have been cleaned and a reaction layer of E-SAFE LIQUID CONCRETE REMOVER has penetrated to the surface.

Cement Mpa and E-SAFE

The higher the cement Mpa the longer it will take for E-SAFE LIQUID CONCRETE REMOVER to penetrate the surface. Typically cement under 48 Mpa can be moved or removed after 5- 15 minutes of product residence time. Precast cement with additives will take longer.

E-SAFE LIQUID CONCRETE REMOVER can easily remove lime and clinker, as the pores and fissures of the deposits are larger, open, and easier to penetrate.  Dulled aluminum trailers will visually brighten after repeated applications.
