So there may be a sealer on the concrete to slow the cure of the concrete. This would have been done immediately after the concrete pour. Information from various paint mfg's say that this should not be used if you are planning to paint the surface or it needs to be removed (acid etched).
Here is the instructions from Quikrete brand. It tests for the sealer. They have a cleaner/degreaser/etcher product.
STEP 1: SURFACE PREPARATION
Before you begin to paint, you must prepare the surface.
This is essential for positive end results.
Remove all items from the floor. The surface must be
clean, dry and free of dirt, grease, oil or other contaminants.
Sweep the floor to remove all dirt, dust,
leaves or any other debris. Scrape up any paint spatters,
caulk and gum. Clean out cracks and corners
as well. Tip: Use a leaf blower after sweeping to
remove any excess debris.
TEST THE POROSITY OF THE SURFACE
Note: Do not apply this product over surfaces which
have been treated with sealers. Use a garden hose to
spray the entire surface. Look for areas of beading
water. Beading water indicates a water repellent
product or sealer is present on the surface. The sealer
must be completely removed before using this
product, as the epoxy may not adhere to a previously
sealed surface.
FOR NEW OR BARE CONCRETE: Allow 60 days
minimum for new concrete surfaces to cure before
painting. Clean and etch new or bare concrete with
BOND•LOK™ Cleaner, Degreaser & Etcher, following
all label instructions. Wet the entire surface with
water. Apply BOND•LOK and scrub the floor thoroughly
with a stiff bristle brush. BOND•LOK should
fizz or bubble on the surface. If it does not, it is an
indication that the surface has been previously
sealed. All previously applied sealers must be completely
removed before using this product. Tip:
When using BOND•LOK, protect all landscaping
nearby. For previously painted or stained concrete:
Clean with an all-purpose cleaner (TSP or
substitute) and dull glossy surfaces by sanding or
using a chemical deglosser. Previously painted concrete
may be repainted only if it has excellent adhesion
to the floor. Test adhesion by pressing heavyduty
tape (i.e. duct tape) at various places on the
painted surface. Pull the tape quickly from the surface.
If the tape removes the previous paint, the
paint must be fully removed before using this product.
Allow floor to dry completely, at least 4 hours or
overnight. Tip: Use a squeegee, wet/dry vacuum or
fan to speed the drying process.
STEP 2: APPLICATION OF THE EPOXY
Open both cans. In a 2 or 3.5 gallon plastic pail, mix
by pouring Part A Base, then Part B Hardener. Stir
the paint manually for 3 minutes, then cover the
paint and let it sit for 30 minutes (activation time) out
of direct sunlight. Tip: Place a tarp outside near your
work area to use as your workstation. Note: Once
you activate the epoxy, you must use it within 6 1/2
hours. After this time, the mixed material cannot be
used and must be disposed of.
Start with a 2-3” brush, and paint a 2” strip along the
edges. Be sure to paint in joints, corners and any
other difficult areas. Use a premium quality medium
nap (3/8") roller for smooth or lightly textured surfaces.
A polyester brush or airless spray is also suitable
for application. If applying by airless spray, back
roll to ensure penetration. Start at the back section
of the concrete floor and spread the paint uniformly,
finishing with long, even strokes. Apply the epoxy in
one direction and then roll it again in a second direction,
perpendicular to the first. This ensures a
smooth, even finish. Repeat application steps over
entire surface. Clean up with xylol.
Drying Time: Dries to the touch in 8-12 hours, wait
12-24 hours for light foot traffic and 72 hours (minimum)
for automobile or forklift traffic.
