The Ultimate in Antimicrobial Protection and Penetrating Concrete Moisture Mitigation

Bone Dry Plus AntimicrobialExcess moisture in concrete is a top concern for contractors working on any major cement masonry project. New concrete requires a lengthy curing period to ensure it is completely dry, which can hold up the construction schedule for days. If steps toward moisture mitigation aren’t taken, adding any covering to a concrete slab becomes a liability.

Even existing concrete floors can have hidden moisture, which may damage flooring materials and coverings and lead to many problems:

  • Expansion and contraction of damp floor coverings resulting in warping, cupping and peeling
  • Adhesives can re-emulsify, allowing flooring materials to come unglued
  • Mold and mildew may populate areas beneath non-permeable floor coverings
  • Items in contact with bare concrete may become damp

Bone Dry Plus Permanently Mitigates Concrete Moisture and Prevents Mold Growth in Slab Floors

Bone Dry Plus has all the benefits of our original concrete sealer, plus additional antimicrobial protection. Mold and microbe growth can be a serious issue where moisture is present, and is particularly troublesome for health care and food service facilities. Applying Bone Dry Plus to any new or existing concrete slab will create a chemical vapor barrier preventing moisture from surfacing, and its unique antimicrobial formula will guard against bacterial growth.

Applying Concrete Sealant is Fast and Easy with Bone Dry PlusAntimicrobial Concrete Sealer

Most epoxy based moisture mitigation solutions require surface preparation. Water-based Bone Dry Plus, however, only requires shot blasting or surface grinding if there is an existing sealant or adhesive. Hard-troweled will need to be etched using our Etch-A-Crete product to optimize the penetration of Bone Dry Plus.

All of our Bone Dry Products can be applied and spread using a common airless weed sprayer. As you apply the concrete sealer, some Bone Dry Plus may soak in quickly. If the amount you’ve sprayed soaks in within 15 minutes, a re-application is needed. Surfaces should be flushed or mopped with water 24 hours after application of Bone Dry Plus to remove foreign material and contaminants brought to the surface.

A five-gallon pail of Bone Dry Plus will cover approximately 1100ft2, depending on concrete porosity. Can be used for both indoor and outdoor surfaces.

Add Quick Dry to Bone Dry Plus for the Fastest Concrete Curing Time

The antimicrobial properties of Bone Dry Plus make it a great option for concrete substrates where mold and mildew growth are expected to be an issue. Home builders and do-it-yourselfers tackling projects of these types are constantly looking for ways to improve efficiency to get the job done fast, without sacrificing product performance. The Quick Dry add-on available for Bone Dry Plus speeds up cure times. Quick Dry is shipped premixed with your sealing product when selected as an add-on, and requires no change to the application process.

Non-Toxic Bone Dry Plus is the Cost-Effective Alternative to Epoxy Sealants

Besides the obvious expenses of replacing moldy, warped or otherwise damaged VCT, wood, carpet, or sheet vinyl floor coverings, resulting from damp concrete masonry, Bone Dry products cost nearly 75% less than common two-part epoxies. These same epoxies can take several days to apply and always require mechanical surface preparation. Between the added costs of material and man-hours, Bone Dry Plus is the best choice for concrete moisture mitigation.

Bone Dry Plus with antimicrobial power provides a unique vapor barrier for waterproofing concrete and dense cement masonry products. Bone Dry Plus penetrates deeply to become an integral part of the concrete, filling the voids and bonding the particles into a solid mass, creating a permanent seal.

Bone Dry Plus with antimicrobial power provides a unique vapor barrier for waterproofing concrete and dense cement masonry products. Bone Dry Plus penetrates deeply to become an integral part of the concrete, filling the voids and bonding the particles into a solid mass, creating a permanent seal.

SEALING • Bone Dry Plus seals concrete and other cement-based materials into a mass that is essentially solid, rather than porous. Its penetrating quality provides deep sealing that provides effective sealing for the life of the concrete.

BONDING • Bone Dry Plus eliminates dusting and flaking and prepares the treated surface for paints, caulking compounds, adhesives, and floor coverings, and increases the bond and life of these materials. It is coatable and compatible with any type of covering.

DENSIFYING • Bone Dry Plus makes concrete substantially harder initially. Concrete continues to harden, but at a slower rate.

WATERPROOFING • Bone Dry Plus becomes an integral permanent part of the concrete by reacting with the free lime and alkali found in all concrete, thus completely waterproofing and strengthening the structure of the concrete.

CURING • Bone Dry Plus is extremely effective in all temperate climates.


Approximately 1,100 square feet per 5 gallon pail, depending upon porosity of the concrete.


If our sealers become frozen in the container, thaw and agitate before use.

Do not expose aluminum, glass, and eyeglasses to our sealers as they could possibly etch the surface.

Do not apply to asphalt as our sealers could break down the petroleum base of asphalt.

Leather shoes and gloves will stiffen. Some glazed tile will be dulled.


Bone Dry Sealers are slightly corrosive to human tissue. Handle as a caustic solution. Protect skin and eyes. Avoid prolonged breathing of vapors or mist. For ultimate protection, especially in confined areas, use a NIOSH approved respirator and wear chemical goggles or face shield and rubber or plastic gloves. Consult the Bone Dry Penetrating Concrete Sealer Material Safety Data Sheet for other safety instructions.


IF SWALLOWED, do not induce vomiting. Drink lots of water or milk, then drink dilute vinegar, lemon juice or orange juice. Get medical attention immediately.

IN CASE OF EYE CONTACT, immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention immediately.

IN CASE OF SKIN CONTACT, thoroughly rinse off immediately with fresh water. KEEP OUT OF REACH OF CHILDREN.


Bone Dry Plus Penetrating Sealer


Bone Dry Plus penetrating concrete sealer is a permanent penetrating concrete sealer with added antimicrobial additive mixed into the product. With added antimicrobial protection Bone Dry Plus prevents mold and mildew from forming in the pores of the concrete slab. This allows any surface mold or mildew to be easily removed from the concrete surface. Bone Dry Plus is easy to apply using a pump sprayer. Our Plus sealer can be applied to new and existing concrete surfaces and can be applied underneath or over the surface of any Portland cement based concrete patch. Our water based product solidifies to fill the pores below the surface of the concrete slab preventing moisture from reaching the surface. Bone Dry Plus can be applied to interior and exterior concrete slabs including slab on grade, slab on deck, garages, driveways, patios and porches, sidewalks, and concrete pavers. When used with our Bone Dry Primer our Plus sealer can be also used over extremely porous concrete block walls. 

Finished Flooring and PH Protection 

Bone Dry Plus sealer protects finished flooring from concrete slabs containing high relative humidity (RH) readings reaching up to and beyond 99% as well as calcium chloride readings reaching 25 lbs. Bone Dry Plus protects adhesives from re-wetting causing finished flooring to delaminate from the concrete surface. This sealer prevents concrete moisture from causing finished flooring failures such as bubbling, discoloration, cupping and bowing, peeling from the surface and other concrete moisture related failures. 

Exterior Protection 

Bone Dry Plus increases the density of concrete extending the life of the concrete slab. It protects exterior slabs and garages from outside elements and salts from penetrating and deteriorating the concrete. Our sealer prevents moisture from penetrating into the concrete which causes aggregate to expand and damage the surface of the slab. Our sealer also protects the slab from becoming damaged in freeze/thaw conditions in colder climates.  

Mold and Mildew Protection 

Bone Dry Plus with its added antimicrobial protection prevents harmful mold and mildew from growing in your concrete slab causing allergy irritation, harmful conditions, and bad odors.

Concrete Floor Preparation 

Remodeled Concrete Surfaces 

Bone Dry Plus sealer must be applied to a clean, porous concrete surface in order to penetrate and react to create a strong barrier. Existing concrete surfaces with prior surface coatings must either receive a top coating of concrete (self leveler, skim coating) or be mechanically profiled with a diamond grinding or shot blasting machine in order to achieve a clean, porous surface. Major floor leveling and skim coating must be completed using a Portland cement based product and be completed prior to applying the Plus sealer. Minor patching and skim coating can be completed after the sealer is applied. Gyp-Crete is prohibited from being used with this sealer. Concrete slabs with known moisture related issues and over 20 years of age must receive a skim coating of Portland cement based concrete prior to applying the Bone Dry Plus sealer. Contact Bone Dry Products for exceptions to this requirement.

New Concrete Slabs 

All construction material and debris (dust, paint, drywall mud, etc.) must first be scraped or broom swept from the surface of the slab. If a slab has received a hard troweled finish, our Etch-a-Crete must be applied or the surface must be mechanically profiled to open the pores of the slab. Major floor leveling and skim coating must be completed using a Portland cement based product and be completed prior to applying the Plus sealer. Minor patching and skim coating can be completed after the sealer is applied. Gyp-Crete is prohibited from being used with this sealer.

Cracks and Trenches 

Any existing cracks (expansion joints not included) with visible gaps must be filled and floated over with Portland cement 6 in. past the crack. Trenches must be floated over the saw cuts 6 inches onto the existing concrete.


Protecting Finished Surfaces 

Any finished surfaces such as cabinetry, glass, finished metal surfaces, and finished painted areas must be masked off with plastic up to 2 feet from the concrete to prevent over spray from causing discoloration. Painted areas affected by over spray can be repainted to address the discoloration. 

Plus Sealer Application Instructions 

Bone Dry Plus sealer can be applied using a pump or battery powered sprayer with a wide fan tip. In 1,000 to 2,000 thousand sq ft sections, apply one coat of sealer so that the slab receives a darkened to light cloudy appearance. Let the area sit for no more than 10 minutes. Apply a second coat to the section while the first coat is still wet. Only apply a second coat in areas where the sealer has penetrated and the texture of the concrete has become visible. If a thick white pool appears on the slab use a broom or brush to spread the product. Once dry, the slab may have a cloudy appearance due to product solidifying on the surface. Contaminants from the slab may rise to the surface as well providing further discoloration.  

Application Instructions at the Pour 

During the pour, use a super plasticizer or other modifier as needed to increase workability while troweling. Do not use a cure and seal or water on the slab. Do not burnish the concrete when troweling. Slab must be porous enough at the surface after troweling is completed to absorb moisture. After the final trowel has taken place, allow the slab to dry for a minimum of one hour and until the slab can be walked on without indenting the slab. Sealer is applied using a wide fan tip pump sprayer. Apply Sealer in 1,000-2,000 square foot sections. Allow sealer to absorb for 5-8 minutes. After 5-8 minutes apply a second coat in the areas that penetrated into the slab. Allow sealer to dry 6 hours prior to opening the slab to foot traffic. If installing finished flooring less than 30 days after pour contact bone dry for approval.


For broom trowel and mechanically profiled surfaces the spread for Plus sealer is 240 square feet per gallon. For hard trowel surfaced where the slab pores are opened with Etch-a-Crete the spread for Plus sealer is 300 square feet per gallon.


Adhesive Application 

The sealed concrete surface must be clean and free of any construction dust and loose particles pushed to the concrete surface prior to applying adhesives. Adhesives applied directly to the sealed concrete surface must be applied as per specifications for a non-porous substrate.
