Can the Ashford Formula be used as a
curing agent?
A. Yes. 50 years of field experience have provided more than ample
proof that the Ashford Formula produces excellent curing results in terms
of ensuring full compressive design strength and minimizing or even eliminating
surface crazing. The Ashford Formula can also be used in conjunction with
other curing mechanisms, such as membrane cures or a wet cure. For details,
call Curecrete or your local agent.
Note: The Ashford Formula is not a membrane, and therefore does not meet
the intent of the ASTM C-309 curing standard for membranes.
back to top
Can the Ashford Formula be used in conjunction
with bond-breakers on tilt-up construction?
A. Yes. Curecrete has on file letters from many bondbreaker
manufacturers certifying that their products will work well on Ashford-treated
casting beds. The Ashford Formula should be applied to the floor/casting
bed at time of placement. The bondbreaker can then be applied later per
usual procedures. Another option is to cure the slab with a dissipating
curing agent, apply the bondbreaker, lift the panels, thoroughly strip
and clean the floor, then apply the Ashford Formula. Note: The Ashford
Formula must be applied to clean, bare concrete so that it can penetrate.
Bondbreakers and/or curing agents must be thoroughly and completely removed
from the floor before the Ashford is applied.

How quickly does Ashford-treated concrete
develop a shine?
A. The shine develops strictly as a result of traffic, use,
and scrubbing. The more quickly the floor is exposed to abrasion, the
quicker it will develop a shine. There are several ways of imparting a
sheen much earlier than it would develop on its own. For hints on these
procedures, please contact Curecrete or your local agent.
back to top
How quickly does Ashford-treated concrete
develop a seal?
A. When the Ashford Formula is applied to concrete, the process
of sealing only begins. The seal is the result of an ongoing chemical
reaction that takes several months to complete. For this reason, the floor
can be susceptible to some staining during the first few months. Curecrete
recommends the following guidelines:
* 1) Diaper equipment that could leak oil or other contaminants.
* 2) Clean the floor regularly with a good detergent and aggressive scrubbing
equipment. As the Ashford continues to react with the concrete, contaminants
will be forced out and removed by the cleaning process. Water from the
cleaning process will also speed up Ashford's reaction with the concrete,
accelerating the seal.
* 3) Clean up spills immediately, and spot-treat any stains with a good
degreaser or oil emulsifier. As the floor matures, it will take on a more
uniform appearance, and any stains will become less and less noticeable.
When the Ashford ultimately seals the floor, the results are permanent.
At this point, frequent cleaning is necessary only to maintain the appearance
of the floor.

How quickly does the Ashford harden and
dustproof the concrete?
A. Within hours of application.
back to top
What if my floor dusts or erodes after it
has been treated with Ashford Formula?
A. When the Ashford Formula is applied to structurally sound
concrete, the surface will not dust or erode. It is a chemical reaction
that takes place 100% of the time. If, however, the concrete surface is
not sound, then the Ashford Formula, when applied at standard coverage
rates, cannot overcome the deficiencies of problem concrete. In every
such case, when the concrete has been tested, the test results have shown
that the concrete surface lacked structural integrity at the time the
Ashford Formula was applied. The most common problems are excessive carbonation
and/or poor water cement ratio. These are surface problems that have nothing
to do with the integrity of the underlying substrate. In our experience,
however, additional Ashford Formula can be applied to such floors with
excellent remedial benefits. With some floors, the problems with the concrete
may be so severe that even more Ashford may not help. If you have a floor
that is abnormally soft or chalky, call Curecrete or your local agent
for guidelines on how to use additional Ashford Formula as a possible
remedy.
back to top
Is the Ashford Formula a coating?
A. No. The Ashford Formula is a chemically-reactive liquid
hardener and densifier. It protects the surface of the concrete not by
coating it, but by increasing the density and durability of the wearing
surface. Once the Ashford Formula has penetrated the concrete and reacted
with it, there is no Ashford left. What remains is a crystalline-densified
version of the concrete that was there in the first place. There is no
coating, film or membrane to scratch, wear, or peel.
back to top
Why do the application instructions call
for removal of excess material?
A. A properly executed application will leave no Ashford Formula
residue on top of the treated surface. Only the material that has penetrated
should remain. If unreacted, unpenetrated material is left on the surface,
it can create white patches if it comes in contact with water. If sufficient
quantities of Ashford are left on the surface, then it can even turn white
on its own, whether it comes in contact with water or not.
back to top
Can I paint stripes on Ashford-treated concrete?
A. Certainly. There is no chemical incompatibility between
Ashford-treated concrete and paints commonly used for striping. Once the
Ashford Formula has penetrated and reacted with the portland cement, there
really is no Ashford left. What remains is a densified version of the
concrete that was there in the first place. The surface is slightly richer
in silicates, but since silicates are in concrete anyway, there is no
chemical reason for a paint not to bond. There can be problems with a
good mechanical bond if the floor surface lacks bite or profile. This,
however, is related to the floor finish, not to the presence or absence
of the Ashford Formula. In such cases, the paint manufacturer's instructions
for roughening the surface should be strictly followed.
back to top
Are Ashford-treated floors slippery?
A. Not any more or less slippery than the surface to which
the Ashford is applied. Co-efficient of friction test results are available
upon request.
back to top
Is the Ashford Formula USDA approved?
A. Yes.
back to top
Is the Ashford Formula toxic, flammable,
or otherwise dangerous?
A. No. The Ashford Formula is an odorless and non-hazardous
material. It contains no solvents or volatile organic compounds. The Ashford
Formula is non-toxic, and produces no harmful fumes or vapors. The Ashford
Formula is completely water-based and environmentally safe. Use of this
product requires no breathing apparatus or protective clothing. For further
information please refer to Curecrete's Material Safety Data Sheet.
back to top
Are two applications of the Ashford Formula
required?
A. No. An optional second application is sometimes used to
provide an early sheen, but this is not necessary to ensure the curing,
sealing, hardening, and dustproofing performance for which the Ashford
Formula has come to be known.
back to top
How soon can I use the floor after it has
been treated with the Ashford Formula?
A. Two to three hours.
back to top
What is the coverage rate of the Ashford
Formula?
A. 200 square feet per gallon.
back to top
Is the Ashford Formula available through
construction supply houses?
A. Generally no, although exceptions have been arranged in
certain instances.
back to top
Does the Ashford Formula require any
thinners or primers?
A. No. The Ashford is ready to use out of the container. No
primers are necessary. The only requirements are that the concrete contains
standard portland cement, and that the surface is bare and clean.
back to top
If my drums of Ashford have been frozen,
can the material still be used?
A. Yes. The material should be thawed out and slightly agitated
prior to use.
back to top
What is the shelf life of the Ashford
Formula?
A. Two years.
back to top
Can the Ashford Formula be applied to
colored concrete?
A. Yes. If the concrete is integrally colored, i.e. the pigment
is added at the batch plant, then the concrete should be fully cured before
the Ashford Formula is applied. If the concrete is stained with mineral
salts, the Ashford should still not be applied until the concrete has
cured for 1 month.
Note: mineral stains are normally applied at 21 days after concrete placement,
so the Ashford Formula can be applied just over a week after the stain.
back to top
Where is the Ashford Formula normally
used?
A. Warehouses, distribution facilities, aviation hangars, manufacturing
plants, food processing and distribution buildings, pulp and paper mills,
or other types of facilities with large exposed concrete floors.
back to top
Does the Ashford Formula work well in
refrigerator or freezer facilities?
A. Yes. It has been used with excellent results for many years
in such facilities. For guidelines, call Curecrete or your local agent.
back to top
Can the Ashford Formula be used with
concrete mixes containing fly ash?
A. Yes, but Curecrete does not recommend using the Ashford
with mixes that contain more than 15% (of total cementitious value) fly
ash.
back to top
Can the Ashford Formula be used with
air-entrained concrete?
A. Yes.
back to top
Can the Ashford Formula be used on exterior
concrete surfaces?
A. Yes
back to top
Do admixtures such as plasticizers, retarders,
or accelerators affect the Ashford Formula?
A. No, provided the admixtures are not present in quantities
that exceed manufacturer's recommendations.
Note: The accelerator calcium chloride has in recent years become less
popular as an admixture. It can cause slab discoloration, increased corrosion
of imbedded reinforcement, increased thermal cracking, and decreased resistance
to sulfates. The problems associated with calcium chloride can occur whether
the Ashford Formula is applied or not.
back to top
Can the Ashford Formula be used with
mixes containing steel or poly fibers?
A. Yes. The Ashford will harden, dustproof, and densify the
concrete paste surrounding the fibers, but will obviously not react with
the fibers themselves. The Ashford Formula has been used successfully
on many steel and poly fiber floors.
back to top
Who can apply the Ashford Formula?
A. The product may be applied on new concrete by owners, contractors,
or qualified applicators. If owners or their contractors apply the material,
Curecrete requires that a field technician be on hand to provide assistance
and ensure the application is done correctly. On existing concrete, Curecrete
recommends that only qualified applicators prepare the surface and apply
the material.
Note: Regarding our International Customers outside of the United States,
the Ashford Formula can be applied only by certified applicators. No other
parties have access to the material.
back to top
What kind of pump is recommend for
applying the Ashford Formula?
A. Curecrete recommends any low pressure, high-volume pump.
As a general guideline, this means a pump that will dispense material
at 40-70 psi and roughly three to five gallons per minute. There are a
number of excellent pumps on the market, most of them simple electric
models with standard garden hose inputs and outputs.
