neutralize concrete after etching.
broom or brush. Only use synthetic brooms and
brushes. Flood entire surface with Concrete Etcher. A
mild foaming action will indicate that the product is
working. Allow product to remain on surface for a
minimum of 30 minutes. DO NOT ALLOW SOLUTION
TO DRY AT ANY TIME DURING THE ETCHING
PROCESS. Mist surface lightly with water to avoid
solution drying. When foaming action stops, scrub
wet product with a stiff bristle brush broom and rinse
entire area thoroughly with water using a garden
hose or pressure washer. Product may become
slippery once applied, work on small enough areas to
avoid walking on treated surface.
IF STAINING CONCRETE:
If you plan to use a concrete stain or paint, neutralize
the etched surface area using Mason’s Select®
Concrete Cleaner, follow all label directions for
neutralizing. Once concrete is completely dry, inspect
all areas of surface before painting or staining. If
properly etched, the concrete surface will be rough to
the touch (similar to 120 grit sandpaper). Repeat
etching process on any areas that are still smooth or
not sufficiently roughened.
EFFLORESCENCE REMOVAL FROM FIBER CEMENT:
Follow application directions for etching, allowing
product to remain on surface for 10 minutes. Mist
surface lightly with water to avoid solution drying.
Aggressive pressure washing or scrubbing is not
necessary. Rinse surface with water and allow to dry
to determine if efflorescence has been completely
removed. Process may be repeated.
