The straight seam-like saw-cuts help
future cracking to follow the pre-cut path
of less resistance in an effort to prevent
unsightly random crack lines. Filling the
seams with
Flexible Joint Compound
prior to a permanent coating being applied
helps minimize problems associated with
soil collecting in the partially-filled cavity.
As with any repair,
surfaces needs to
be clean and dry
before installing the
joint compound.
Epoxy Primer
After the surface has been cleaned and
patched, it is ready for priming. A primer
penetrates the concrete surface to stop
dusting and make the surface super hard.
A primer fills in concrete surface voids and
acts as a liquid double-sided tape to grab
onto the next coat to ensure the bond.
When each succeeding coat is bonded
well and the concrete surface is super-
hard, problems of peeling, gouging, flaking,
etc. are minimized or prevented.
Correcting Spalled (Pocked)
or Unlevel Surfaces
(Optional)
The last step before
starting the application
of the epoxy primer
is to check the look
and feel of the surface.
Is the surface level,
rolling, pockmarked
(spalled), with golf-like divots, or pitched?
Severly pitched, pocked, or golf divot-type
dents should be reviewed with Gabriel
before proceeding. Gabriel
Con-Patch
epoxy mortar will be needed in the very
deep parts of the damaged areas.
If the texture and the pitch of the floor is
acceptable, move to applying the traffic-
bearing top coat(s) over the set primer.
If you wish to smooth or re-pitch the surface,
mix and apply
Levelex
or
Tuf ‘N Qik
over
the set primer
.
They are two-part high-
build 100%-solid epoxy liquids.
Levelex
has a granular third ingredient to produce
a thicker build for use in severely rough,
patched, or damaged conditions.
Both products are spread with a V-Notched
Trowel or Squeegee and produce a super-
hard base over which top finish coatings
are to be applied.
Top Finish Coating(s)
In addition to making a floor look bright
and inviting, the job of a floor coating is
to help prevent concrete deterioration
or discoloration as well as to help cut
the cost of cleaning and upkeep.
Permanent Coating
compared to
Provisional Sealer
Permanent products are called coatings.
They protect the concrete from extreme
traffic wear, harsh acids, oils, and even
brake and hydraulic fluids. Permanent
coatings are locked to the substrate by
the interlocking of each previous coat.
Permanent coatings come in a variety of
solvent or water-based formulations:
1. Standard Epoxy
2. Novolac Epoxy
(Chemical Resistant)
3. Urethane
(Chemical Resistant)
Permanent
coatings normally come in a
2-part, clear or pigmented, liquid system
that gets mixed just prior to application.
The finished job should look like a well-
painted floor—the only difference is that
the bond of each coat is inseparable.
To make a decorative floor, colored vinyl chips
are broadcast into an epoxy flood coat and
then capped with coats of clear urethane.
For added slip-resistance, #60 aluminum
oxide powder may be added into final coats.
For added slip resistance and/or in an
industrial application, the vinyl chips
may be replaced with a single- or multi-
color-blend of granular quartz aggregate.
Provisional Sealers:
Gabriel
Premier
is
a provisional, single part, water-based
sealer for concrete.
Premier
is extremely
tough and may be applied to a variety of
surfaces from bare concrete to paint or
most any permanent coating.
A
Provisional
sealer is used to:
1. Help prevent premature scratching
and wearing of permanent coatings.
2. Restore gloss quickly & inexpensively.
3. Make upkeep easier and less expensive.
On bare concrete, a
Provisional
sealer/ finish
can halt concrete wear
and dusting as well as
produce high gloss.
Gabriel
Premier
works
as does a regular floor
finish—burnishable
and strippable.
