Clear, concentrated mold and moisture resistant sealer for the protection of structural materials after water/flood restoration services as well as for the boosting/resurfacing of existing Enviroguard coatings in unconditioned and accessible spaces.

*Treated Articles Exemption - This product contains an EPA registered antimicrobial to protect the coating from non-public health fungi and odor causing bacteria. No public health claims are being made.


  • Penetrates and bonds to both existing Enviroguard protective coatings and structural surfaces.
  • Creates a clear and durable protective finish
  • Breathable to allow drying and to help prevent dry or wet rot conditions
  • Moisture resistant to help control moisture content
  • Bacteria, Algae and Fungi resistant for long-term protection of the sealant
  • Water-based and non-flammable


Fortify is used to resurface Enviroguard Protective Coatings and protect most structural construction materials for up to 12 months including treated and untreated lumber, plywood, OSB, particle board, cement board, wallboard, composite construction materials and metals. Probable areas of use are structural surfaces within the building envelope including warm-side sheathing, trusses, framing, joists, plates, pillars, posts, beams, gypsum board and backer board.

Coverage Rate

For resurfacing Enviroguard Protective Coatings, use a 9-to-1 dilution (9 parts water to 1 part Fortify). Apply at a rate of 160 ft2 per gallon of ready-to-use solution. Coverage may vary due to surface texture, porosity, age and application method. This does not include loss from over-spray or over-use.
For structural materials, use a 2:1 dilution (2 parts water to 1 part Fortiy). Apply to the point of run-off at a rate of up to 300 ft2 per gallon of ready-to-use solution.

Shelf Life & Storage

24 Months

Use and Instructions


Use in moisture prone environments where Enviroguard coatings are accessible such as unconditioned attics, basements and crawl spaces.


Fortify should be applied directly to the surface to the point of saturation but not past the point of run-off. Once diluted, Fortify is a low viscosity sealant. For application to existing Enviroguard Protection Coatings, fog apply the diluted solution of Fortify to the point of run-off. For structural materials, a pump sprayer, fogger, electrostatic sprayer or airless sprayer (or any other similarly powered sprayer) should be used.

Your Problems

Fortify was designed with the building envelope in mind in order to solve specific new and existing construction moisture problems.

Following floods and natural disasters, restorers are pushed beyond capacity as demands on time and labor exceed resources. The need to move quickly and meet insurance carrier demands can result in structures that don't meet your /or industry dry standards.

Additionally, even the best products have limitations. As protective coatings age, antimicrobial capacity and moisture resistance wane. Without maintenance, protective capacity degrades gradually to the point where moisture related issues can return.

Our Solutions

Maintain Pace

Fortify forms a breathable yet moisture resistant barrier on structural surfaces with our award-winning antimicrobial protection. Also, it can be used with the same equipment that you use for cleaning and disinfecting.

Uphold Efficacy

Reinvigorate existing Enviroguard base coating performance (moisture resistance and antimicrobial capacity) and create a sustainable profit center in your business, all while providing your customers with the peace-of-mind of an annual maintenance program.

Transparent Protection

Transparent protection allows you and your customer (including IEPs or Industrial Hygienists) to see that surfaces have been cleaned without changing the way structural surfaces look.

Award Winning Protection

In 1996, our antimicrobial won the 1996 Presidential Green Chemistry Challenge Award for Designing Safer Chemistries. It's leach resistance ensures a long service life. It's non-persistence in the environment prevents pollution and liability.

Uni-Directional Breathability

Fortify is breathable to prevent against locking in moisture which could lead to wet or dry rot conditions. This works by allowing water vapor to escape from structural surfaces while preventing absorption from the environment.
