Fortify is a concentrated, clear booster used to resurface and restore current Enviroguard coating systems
or to impart short to mid-term mold and moisture resistance onto wood-based and cementitious construction materials after cleaning or restoration services.

*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.

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.


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


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.


  • 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*


Consult SDS for details


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.
