BacShield (Surface Protectant) 1 Pint with Spray Bottle

1 Pint: 21:1 concentrate = makes almost 3 ready-to-use gallons!


BacShield is a product of modified carbohydrates found in crab shells, a plentiful renewable resource, and incorporates the environmentally derived antimicrobial properties of these crab shells into a treatment for textiles and surfaces. 

BacShield is intended as a treatment, in order to give anti-bacterial and anti-fungal protection to the treated materials, and inhibits the growth of bacteria, mold, mildew, and fungus that cause odor, stains, discoloration, decay and deterioration of the treated materials.  This product is perfect for HARSH environments and outdoor surfaces like fences, sidewalks, roofs, vinyl siding, patios, decks, and otherhorizontal or veritical surfaces.


  • Easily applied by spraying or soaking

  • Controls the source of odors instead of covering up odors

  • Treated materials are resistant to odor and decay caused by growth of bacteria, mold and mildew

  • Protection against odor and decay for:

    • Clothing, hosiery and footwear

    • Vehicle interiors

    • Upholstery and mattresses

    • Carpets, curtains and wall coverings

    • Paper and wood products

  • Recommended for use in:

    • Automobiles, buses, boats, planes, and recreational vehicles

    • Restaurants and Cafeterias

    • Public seating areas such as theaters, stadiums, and airports

    • Schools, Dormitories and Athletic facilities

    • Medical offices, Assisted living centers

    • Basements, Attics, and other damp areas where odors can grow


As a spray or mist for non-food hard contact surfaces such as but not limited to wood, masonry, particleboard, vinyl, metal, fiberglass, other interior and exterior surfaces.

Step 1: Prepare

Clean surfaces to be treated with appropriate cleaner to remove dirt, mold, mildew, fungi, or any other organic matter. Materials to be treated should be dry prior to application for maximum adhesion and effectiveness. Substrates such as wood and wood containing products should contain less than 12% moisture prior to application for maximum effectiveness and longevity.

Step 2: Protect

  • Add 9 ounces of BacShield per gallon of working solution (9 oz BacShield + 119 oz water)

  • Apply as a spray or mist until surface is completely covered and wet

  • Allow drying before re-coating (if desired) or covering with insulation, or other building materials

NOTE: The normal dilution ratio is

  • 6 oz Bac-Shield per 1-gallon of solution 

  • 1.5 oz Bac-Shield per 32-oz of solution 

The normal dilution should be used when treating very porous materials and you can thoroughly dry the materials.


Laundry:      Apply to each load

Method 1: Most Economical

As an “after-wash spray treatment” for all athletic wear, clothing, linens, uniforms, textiles in general:

  • Remove laundry from washer after final spin cycle

  • Mix 6 ounces of Bac-Shield per 1-gallon of water in pump-sprayer or mix 1.5 oz. in 32 oz spray bottle

  • Spray each article with Bac-Shield solution until completely covered

  • Dry thoroughly before use

Method 2: Most Convenient

As a laundry additive:

  • Run laundry through entire wash cycle

  • Re-set washer to rinse cycle

  • Add Bac-Shield to fabric softener receptacle or directly onto laundry

  • Repeat rinse cycle

  • Dry laundry thoroughly

Washer Type: Domestic/Coin Operated – Less than 30 lb capacity

                                                                           Front Load                   Top Load

Cotton and cotton blends                                  1.75 oz / load                4 oz / load

Nylon, Polyester & Other Synthetics                  6.5 oz / load                  15 oz / load

Carpet, Upholstery, Drapes, Pet Bedding:  

Apply monthly or as needed for odors caused by bacteria, mold, milder, or fungi

  • Apply to clean carpet or fabric 

  • Check for discoloration or water spotting in an inconspicuous area. 

    • Discoloration is not expected on fabrics where water spotting does not occur.  Leather and silk are typically prone to water spotting.

  • Small Area: Add 3 oz Bac-Shield in a 32-oz hand-held spray bottle and apply as a spray or mist at a rate of 1-gallon solution per 110 sq. ft. coverage for the 32-oz spray bottle

  • Large Area: Mix 12 oz Bac-Shield per gallon of water in pump-up garden sprayer and apply as a spray or mist at a rate of 1-gallon solution per 540 sq. ft. surface area for carpet

  • Carpet should be cleaned regularly as recommended by carpet manufacturer

  • Allow to dry before use

NOTE: The normal dilution ratio is 6 oz Bac-Shield per 1-gallon of solution (6 oz Bac-Shield + 122 oz. water) or 1.5 oz Bac-Shield per 32-oz of solution (1.5 oz Bac-Shield + 30.5 oz water). 

The concentration of Bac-Shield can be doubled as shown above to cover twice as much area with the same amount of solution.  This is done to minimize the amount of water used to cover the same area.  The normal dilution should be used when treating very porous materials and you can thoroughly dry the materials.

Exercise Equipment, Benches, Mats, Surfaces, Protective Gear, Helmets, and Pads:

  • Apply daily to exercise equipment, surfaces and mats

  • Apply weekly or as needed for bacterial odor

  • Directions

    • Clean articles to be treated

    • Mix 6 oz Bac-Shield per 1-gallon of water in pump-up sprayer or Mix 1.5 oz in a 32-oz hand-held spray bottle

    • Apply as a spray, mist, or wipe with soaked cloth until surface is thoroughly damp

    • Allow to dry thoroughly before use

    • FAQ’s

    • Q: Can you provide some estimates for coverage on porous and non-porous surfaces?

    • A: Yes.  One general rule to remember is that we need to have complete coverage, so the goal is to form the 'shield'. For mold /mildew prevention use 6-9 ounces of BacShield per gallon of solution.


    • One end of the spectrum includes porous (absorptive) surfaces such as concrete or other masonry applications. One gallon of solution will cover approximately 270 square feet of surface area.

    • WOOD

    • Wood (unpainted or otherwise unfinished) falls somewhere in the middle and one gallon would treat approximately 500 square feet of surface area.

    • VINYL

    • Vinyl and other non-porous substrates can be treated at a rate of approximately 750 square-feet per gallon of solution.

    • Q: Does the product tend to run on vertical hard surfaces such as concrete, vinyl siding, etc.?

    • A: Yes. The viscosity of the solution is very low, not much higher than water.

    • Q: Would we approach it as a fog application (9 to 11 spray tip) or a paint application (15 to 17 spray tip)?

    • A: A fine spray is very desirable for both coverage and to minimize runoff. Each applicator can decide which method works best for them.


    • Storage Temperature: above 40°F is recommended

    • Shelf Life: 2 Years

    • Store in dry place at ambient temperature.  Keep containers covered to prevent contamination.
