Concrete Etch

Liquid Rubber Concrete Etch contains a granular base, that is mixed with warm water to create an etching solution suitable for removing Laitance and Efflorescence in preparation of concrete, stone, and masonry surfaces prior to coating. The life of any coating is dependent on adhesion to a clean, sound surface. Etching the surface removes contaminants and minutely roughens the surface, as well a neutralizing the PH of the concrete and masonry, to ensure strong adhesion and a long-lasting coating.

1 Circle around step number design detail

Mix the granular contents of 1 package of Liquid Rubber Concrete Etch (500G) to 3 L / 0.79 Gal. of clean warm water in a plastic pail or chemical resistant garden sprayer for bleach. Stir the mixture until the powder is completely dissolved.

2 Circle around step number design detail

Wet the surface of the concrete by pressure washing and remove any standing water from the surface. Pressure washing also helps to ensure that the surface is clean prior to etching.

3 Circle around step number design detail

Apply the etching solution to the concrete while the surface is still damp using a garden sprayer or by dipping a stiff bristle broom into the solution and scrub the surface vigorously for 1-2 minutes. The surface should foam up slightly.

4 Circle around step number design detail

Leave the solution on the surface for 30 minutes, scrubbing occasionally. Do not let the surface dry during this time, apply more etching solution if needed.

5 Circle around step number design detail

Rinse the surface well by pressure washing and allow the concrete to completely dry, this should take around 48 hrs. (depending on temperature and humidity)

6 Circle around step number design detail

Note

Etched surface should feel like 150 medium grit sandpaper. This process may need to be repeated for exceptionally smooth or power troweled concrete.

WARNING

The etching solution (once mixed) will be an acidic mixture and proper protective equipment, such as safety glasses, goggles, and chemical resistant gloves, should be used throughout the etching process.
