Q:
How does this product differ from other sealers that claim to protect
concrete?
A:
StableCrete is not a
sodium silicate or silene based product. It does not migrate out of
the concrete becoming ineffective after a few months and readily
accepts any coating to a treated surface. Our product has no
provision for a second coating or re-application at a later date. It
is also has no harmful affects ( etching ) on glass and metal
surfaces. Question to consider? If the specifications on some other
product calls for a re-application—what happened to the first
attempt? |

Q:
Can I paint concrete treated with your product?
A: Absolutely! Dozens
of coating manufacturers test data reports better adhesion and cover
age rates. Coatings are not subject to alkali burn, peeling and flaking
as the chemicals in concrete no longer migrate to the surface, commonly
called outgasing. |
| 3 |
Q:
Will StableCrete protect against carbonation of concrete?
A: The reaction of atmospheric
carbon dioxide and calcium hydroxide causing carbonation and a loss
of pH does not occur when the surface has been treated with StableCrete. |
| 4 |
Q:
Can and should this product be used with other corrosion inhibitors?
A: StableCrete is a
very affective means of encapsulating a liquid amino alcohol based
corrosion inhibitor. It will prevent those products migration out
of the concrete matrix |
| 5 |
Q:
Does StableCrete penetrate concrete and coat reinforcing steel to
inhibit corrosion?
A: No. StableCrete prevents
oxygen and water from entering the gel pore system as well as contaminates
such as chlorides. This also maintains high pH levels promoting the
natural passivating layer on embedded steel. |
| 6 |
Q:
I have cracks in my concrete. Should I fill the cracks before applying
StableCrete?
A: No. StableCrete will
waterproof the interior of a crack just as it does a surface, then
your filler material may be applied. |
| 7 |
Q:
Can StableCrete waterproof shotcrete?
A: StableCrete is very
effective on waterproofing these types of structures. Shotcrete (wet
or dry mix) has a very high cement content which promotes a very aggressive
reaction due to the increased alkali content Coverage rates may be
reduced with higher absorption of shotcrete. |

Q:
I have recently installed an impressed cathodic system (top surface
saw slot) on elevated concrete slabs. Can StableCrete be applied to
the finished surface?
A: Assuming your finished
surface is a cementitious material which will allow the alkali to
react with StableCrete; YES. Testing shows that StableCrete has "little
to no effect "on the resistivity of concrete. By use of StableCrete
you will waterproof the surface and prevent changes to current flow
which cause "hot spots" and premature consumption of anodes. |

Q:
Your literature indicates the application of StableCrete in "Green"
concrete is more effective. Is it a curing compound?
A: StableCrete is not
promoted as a curing compound or evaporation retarder and does not
form a film discussed in the ASTM protocol. Practically speaking,
the high moisture content of new concrete causes a capillary effect
which carries the product deeper into the matrix. Once introduced,
StableCrete IS the best curing compound on the market. |
| 10 |
Q:
Will StableCrete stop efflorescence on driveway pavers?
A: One of the products
in our StableCrete line is efflorescence remover which will remove
the salts. To determine whether StableCrete will stop efflorescence
in the future, a test to determine the chemical makeup of your pavers
(% of Portland Cement) would be needed. |
| 11 |
Q:
Is a special repair/patch mortar used if StableCrete is to be applied
later?
A: Synthetic repair/patch
materials are very expensive and do not contain the high alkali content
of Portland Cement which is the catalyst for StableCrete. Quickrete
bag mix is our recommendation. |
| 12 |
Q:
Do I apply my bonding after I have applied StableCrete to an excavated
repair area which is to receive new concrete?
A: Bonding agents are
used to prevent hydration from a patch material into the host substrate
which causes bond problems and cracking at the interface (old &
new). StableCrete penetrates the host substrate and waterproofs at
that point leaving no film (bond breaker) to contend with. Knowing
this, why would you want to apply a bonding agent at all? |
| 13 |
Q:
Can StableCrete be used on an
aged structure hoping to extend the life cycle?
A:
Aged concrete may be treated after all
coatings and contaminates have been removed from the surface. A
simple test with water will demonstrate the concrete is absorbing
water. If so, StableCrete will be absorbed in the same manner and be
able to keep moisture and contaminates out of the structure thus
prolonging useful life. |

Q:
I have a building with painted
concrete floors, which show areas where the paint is peeling off
especially around columns—will this product help me?
A:
Sounds as if you have alkali coming up
to the surface out of the concrete collecting on the back side of
your coating causing a bond failure. More than likely the reason it
is more visible around columns is because those columns have a
footer/pour that extends deeper into the soil than your slab. This
depth is causing ground water to wick up to the surface in greater
quantities than the slab which also has a vapor barrier under it.
Air conditioned buildings aggravate this water vapor emission. A
proper StableCrete application will serve to prevent this transfer
of moisture. |

Q:
I have an oceanfront seawall that
is showing cracks and rust stains from the sand about 18 inches up.
We have placed a repair mortar in the cracks but the cracks keep
coming back and the repair material falls out. Will StableCrete help
me?
A:
Sounds like you have very active
corrosion on the steel and the rust on the steel is pushing the
concrete away (Spalling) at this location. This area (the splash
zone) is much more prone to corrosion than that above or below the
water. The constant wet- dry cycle delivers more moisture and salt
contaminates to this area causing an acceleration of rust on the
re-bar. When you replace this wall, StableCrete should be applied to
waterproof all concrete surfaces, but for now no amount of
StableCrete or repair will stop these conditions. |

Q:
I purchased an oceanfront
condominium that had a concrete restoration done on our balcony’s
four years ago. We now have cracking that extends inside underneath
the sliding glass doors into living and bedrooms; will this stuff
stop the cracking?
A:
Probably Not! You may have anodic ring
or halo affect causing the corrosion to migrate into the original
concrete. Incipient battery affect occurs when new concrete is
placed next to an aged material (the patch interface). The two
different pH values cause a more aggressive corrosion to travel. The
second repair is called “chasing the steel “and only exacerbates
your problem. An impressed cathodic system using StableCrete to
waterproof all concrete is the only certain way to stop continued
corrosion and repairs to the concrete. Sorry! |

Q:
I purchased a home now six years
old and have window sills that have large cracks under the windows
outside. I am told these sills must be replaced. Will your product
stop this cracking?
A:
No! You probably have precast lintels
that have active corrosion on the steel causing this Cracking
condition. When you replace them, treat the new precast members with
StableCrete. Precast products are subject to corrosion of the steel
inside the same as poured concrete. By protecting the steel inside
concrete from moisture/contaminate intrusion you will prolong the
life. |
