BASIC USE: Ashford Formula, a leader in concrete densification since 1949, is a transparent, chemically reactive, water-based treatment that penetrates concrete and masonry building materials, protecting, preserving and strengthening them permanently by:
CURING: Ashford Formula controls hairline checking on new concrete. When applied to properly placed, structurally sound freshly finished concrete, Ashford Formula will uniformly cure the concrete through a combined chemical/moisture retention reaction so vital to the complete hydration process
DENSIFICATION: Ashford Formula penetrates into the concrete surface, forming a chemical reaction of crystalline growth that fills in the natural pores and voids in the concrete surface
HARDENING: Ashford Formula solidifies the component parts of the concrete into one solid mass, increasing the density, toughness, hardness and substantially increasing the abrasion resistance and durability of the concrete surface. Smooth steel-troweled surfaces develop a marble-like finish and sheen
DUSTPROOFING: Ashford Formula chemically reacts with the salts in the concrete, permanently eliminating the release of concrete dust through the surface pores
NEUTRALIZING ALKALI: As the Ashford Formula progressively penetrates the concrete, it neutralizes the alkalis, forcing them to the surface where they can be washed away during the application; the deep alkalis are locked in, and efflorescence and the leaching of lime and alkalis stop
BONDING: Ashford Formula prepares the treated surface for paints, caulking compounds, adhesives and floor coverings by eliminating the surface concrete salts that are so detrimental to proper bonding; Ashford Formula contains no silicone and is coatable and compatible with any type of covering when standard surface preparation guidelines are followed
With one application of Ashford Formula, concrete or other masonry is cured and rendered permanently more dense for its lifetime, making oils, greases and other surface contaminants easier to clean and remove. The component parts of the concrete are solidified into a solid mass that toughens, hardens and increases the density. Surface alkalis are neutralized, and efflorescence and the leaching of lime and alkalis are stopped.
Treatable materials include concrete, heavyweight concrete block, mortar, plaster, stucco, terrazzo, exposed aggregate and any sand-aggregate-portland cement combination. Applications include 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.
Applying the Ashford Formula does not require a lot of time, or involve complicated procedures. If applying to existing concrete, the floor needs to be prepared so that it is clean, bare concrete. This means that curing agents, dirt, paints, coatings, bondbreakers, oil spills and other contaminants are stripped and/or removed completely.
For optimum performance, the Ashford Formula must be able to penetrate the surface so it can react with the concrete.
Only one application of the Ashford Formula is needed to permanently densify the concrete surface.
The normal application procedure (whether new or existing concrete) is to spray the Ashford Formula on the surface of the slab with a low-pressure, high volume sprayer. Airless sprayers are not recommended.
The material should be applied at approximately 200 ft2/gal (5 m2/L) to achieve a flood coat on the floor surface. This means that when someone steps on the applied material, the footprint of their shoe should disappear within 3 or 4 seconds.
Once a flood coat has been achieved, the material should be agitated with fine-bristled brooms to help it penetrate the surface of the concrete.
The material should dwell on the surface for a minimum of 30 minutes and become gel-like or slippery. In hot conditions, it may become slippery prematurely. If this occurs, it is necessary to fog or mist the floor with water to keep the Ashford Formula in a liquid state for the entire 30-minute period.
When the Ashford Formula turns slippery after the 30 minutes has elapsed, it can be flushed away with water.
While the water is on the slab, the surface should be broomed to loosen all excess Ashford Formula from the surface of the concrete. Squeegee dry. Allow to dry for 2 to 3 hours.
The final flush, broom, and squeegee steps can also be accomplished with an automatic scrubbing machine. These machines can dispense the needed water, broom, vacuum, and squeegee dry, all in one easy pass.
The Ashford Formula densifies with a unique and unmatched catalytic chemistry. Nearly 70 years ago, the Ashford Formula was developed as an alternative to coatings. When this product first came on the market, there were many skeptics who could not believe that one product could permanently make floor surfaces resistant to abrasion, easy to clean and free of dust.
Almost seven decades of performance have proven them wrong. These permanent results are achieved through the unique and unmatched catalytic chemistry. The concept is very simple: a concrete floor surface is internally densified through a process of crystalline growth. The same reaction also hardens the concrete and locks up the dust. Because the chemistry is inorganic, there is nothing to wear out, scratch or peel.
Concrete floors need to be durable. The Ashford Formula makes concrete abrasion resistant. In fact, abrasion testing shows that an Ashford Formula treated floor will be 32% harder within the first 30 minutes of treatment. The treated concrete will continue to harden over time. The Ashford Formula also acts as a supplement to surface and aggregate hardeners. .
When used as a curing agent, the Ashford Formula slows the outward migration of water from concrete. Its chemical reaction forms a densified barrier that reduces shrinkage, reduces cracking and reduces hairline checking. And, we have the testing to prove it.
Concrete floors need to be free of dust. Concrete naturally creates dust from efflorescence, which then settles on finished goods, racks and equipment. The Ashford Formula combines with the salts in concrete to become an integral part of the concrete, thus completely dustproofing the surface. This substantially reduces maintenance costs and protects sensitive equipment and manufactured products from dust particles.
The Ashford Formula reduces construction costs. It requires only one, permanent application. This eliminates the need to apply a curing membrane, which requires removal from the floor at a later time. When used at the time of placement, the Ashford Formula also significantly reduces crazing, or “map cracking” because it stabilizes the surface. This property of the Ashford Formula makes it especially useful for outdoor applications because it makes the concrete resistant to freeze-thaw damage. The Ashford Formula eliminates the need for repeated applications of urethanes, waxes, acrylics and other expensive maintenance-intensive floor coatings.
Because the Ashford Formula permanently densifies concrete, foreign matter such as oil, alkali, free lime and traffic scum are easily removed with regular cleaning. A regular maintenance program is highly recommended for any floor to remove surface contaminants and any acids or other corrosive materials should be removed immediately from the floor.
Steel troweled concrete floors treated with the Ashford Formula also take on a permanent and attractive marble-like sheen. The longer these floors are subjected to cleaning and traffic, the better they look. Floors treated with the Ashford Formula also have fewer tire marks from forklifts and other equipment. If tire marks do occur, they can be easily removed.
For years, the only approach to protecting concrete floors was to cover them with a film or membrane. Such products include acrylics, urethanes, epoxies and waxes. By their very nature, however, coatings are only a temporary solution. They are subject to delamination, scratching, chipping and wear. Eventually, they have to be replaced. This involves the expense of downtime, materials and labor. Some inexpensive coatings last only as little as 6 months to a year, so the associated maintenance costs are frequent and high.
The Ashford Formula takes a different approach to concrete floor protection. Rather than coating the surface with organic solids, the Ashford Formula grows new crystals in the concrete. This reaction fills in the natural pores and voids in the concrete and provides a dense, hard surface that is easy to clean. The concrete is densified internally and inorganically. There is nothing to wear off the surface, nor is there anything to replace. The same reaction also makes the surface much harder and resistant to abrasion. In addition, the floor surface is rendered free of dust.
The idea of achieving these results was initiated nearly 70 years ago by the Ashford Formula. This is the product that created an entirely new industry. Because of the success of the Ashford Formula, many imitations have come on the market. None of them, however, can match the long-term performance of the original. No one has the same unique catalytic chemistry that has delivered results lasting almost 70 years. No one has the same Lifetime or 20-year warranty that is validated by nearly seven decades of proven performance.
The Ashford Formula is available internationally in 208L drums. In the United States, it is available in 55-gallon drums or 5-gallon pails.

Yes. Decades of field experience has 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.
Note: The Ashford Formula is not a membrane, and therefore, does not meet the intent of the ASTM C-309 curing standards for membranes.
Yes. Curecrete has letters from many bondbreaker manufacturers certifying that their products will work well on Ashford Formula treated casting beds. The Ashford Formula should be applied to the floor/casting bed at the 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. Bond-breakers and/or curing agents must be thoroughly and completely removed from the floor before the Ashford Formula is applied.
The marble-like sheen 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.
How quickly does Ashford Formula treated concreted develop a seal?
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 Formula 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 the reaction of the Ashford Formula with the concrete, accelerating the seal.
3 – Clean up small 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 Formula ultimately seals the floor, the results are permanent. At this point, frequent cleaning is necessary only to maintain the appearance of the floor.
The Ashford Formula hardens and dustproofs the treated concrete surface within hours of its application.
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.
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.
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 un-reacted/un-penetrated 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.
Certainly. There is no chemical incompatibility between Ashford Formula 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.
Not any more or less slippery than the surface to which the Ashford Formula is applied. Co-efficient of friction test results are available.
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.
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 is known for.
Two to three hours.
The coverage rate of the Ashford Formula is 200 ft2/gal (5 m2/L).
Generally no, although exceptions have been arranged in certain instances.
No. The Ashford Formula 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.
Yes, the material should be thawed out and slightly agitated prior to use.
Indefinite. Agitate before use if product is more than 1 year old.
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 Formula 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.
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.
Yes. It has been used with excellent results for many years in such facilities. For guidelines,
Yes, but Curecrete does not recommend using the Ashford with mixes that contain more than 15% (of total cementitious value) fly ash.
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.
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.
In the U.S. and Canada, the Ashford Formula 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.
For International Customers, application of the Ashford Formula is monitored by our exclusive network of Distributors. Please contact the Distributor in your country or the Managing Director in your region to learn who can apply the Ashford Formula in your area.

The Ashford Formula™ can contribute points if the project is within 500 miles of where it is manufactured – Springville, Utah.
Indoor Environmental Quality Credit 3.1: Construction Indoor Air Quality Management Plan: During Construction
Intent: Reduce indoor air quality problems resulting from the construction/renovation process in order to help sustain the comfort and well-being of construction workers and building occupants.
The Ashford Formula can contribute points because it is a flooring product, and an alternative to carpet. This standard calls for sequencing construction so that “absorptive materials” such as insulation, carpeting, ceiling tile and gypsum wallboard” do not become contaminated and thus degrade the safety of the working environment. Concrete floors treated with the Ashford Formula are not absorptive like carpet, and are therefore not susceptible to such contamination.
Indoor Environmental Quality Credit 3.2: Construction IAQ Management Plan: Before Occupancy
Intent: Reduce indoor air quality problems resulting from the construction/renovation process in order to help sustain the comfort and well being of construction workers and building occupants.
The Ashford Formula can contribute points because it is based completely on inorganic chemistry, and therefore does not contribute whatsoever, to the presence of formaldehyde, particulates, VOCs, and 4-Phenylcyclohexene. Further, the Ashford Formula produces no fumes, vapors, or off-gassing, which is not the case with most floor coatings and floor coverings.
Indoor Environmental Quality Credit 4.1: Low-Emitting Materials: Adhesives & Sealants
Intent: Reduce the quantity of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.
The Ashford Formula can contribute points because it dispenses with all floor coverings and allows exposed concrete floors to be used as the finished working surface. This standard specifically references sealants and adhesives, such as those used on carpet, carpet pads, rubber floors, VCT and ceramic tile, which the Ashford Formula does not use.
Indoor Environmental Quality Credit 4.2: Low-Emitting Materials: Paints & Coatings
Intent: Reduce the quantity of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.
The Ashford Formula can contribute points because it contains no VOCs whatsoever, and is compliant with this standard. This standard calls for low-emitting products compliant with the South Coast Air Quality Management District (SCAQMD) Rule 1113 in effect on January 1, 2004. The Ashford Formula is classified as a concrete and masonry sealer. This type of product must have a VOC content of less than 100 g/L.
Indoor Environmental Quality Credit 7.1 and 7.2:Thermal Comfort
Intent: Provide a comfortable thermal environment that supports the productivity and well-being of building occupants.
The Ashford Formula™ can contribute points by retaining the inherent thermal properties of concrete to reduce the cooling load and heating load of the building, thus increasing the thermal comfort of the occupants. The Ashford Formula™ treated concrete increases the benefits of in-floor radiant, or solar heating and cooling systems by maximizing the building envelope’s thermal mass.
Innovation & Design Process Credit 1 – 1.4: Innovation in Design
Intent: To provide design teams and projects the opportunity to be awarded points for exceptional performance above the requirements set by the LEED for New Construction Green Building Rating System and/or innovative performance in Green Building categories not specifically addressed by the LEED for New Construction Green Building Rating System.
The Ashford Formula™ avoids floor coverings and coatings. Maintenance of an Ashford Formula™ floor is simple and very environmentally friendly, using water or a water-based detergent and reducing the floor’s life cycle cost. The sealed surface provides allergy relief to occupants because it does not harbor pollen or mold. The Ashford Formula™ will perform well under conditions of temperature change, and wet conditions, incase of natural disaster or other emergency.
Implementation of the following maintenance program will allow the Ashford Formula to continue to react with the concrete, lifting contaminants away from the concrete and allowing the marble-like sheen to develop.
Scrub Floor Often: Minimum routine cleaning 2-3 times per week with CreteClean Plus with Scar Guard provides superior results.
Clean Spills Quickly: After densification is complete, concrete will resist contamination and moisture penetration of most liquids. Corrosive or aggressively staining contaminants should be removed quickly to avoid possible staining.
