Fiberlock RECON Smoke Odour Sealer Clear
RECON Smoke Odour Sealer encapsulates malodors on structural surfaces and blocks the toughest stains, typically found on fire damage restoration projects.
Unlike typical water-based coatings that “wick” smoke odours and stains out of the substrate as they dry, RECON Smoke Odour Sealer with OdorLock technology prevents smoke odours and stains from migrating through the coating while maintaining its breathability.
Get one-coat odour control and continue to block odours even with seasonal changes in temperature and humidity when you use RECON Smoke Odour Sealer as your final step to encapsulate residual odours.
Features

- Can be applied in the ductwork
- Available in a tintable white or clear
- Excellent stain blocker
- Water-based and non-flammable
- Bonds to nearly any substrate
- Ideal for use in wall cavities
How to Use
SURFACE PREPARATION
Prior to applying Fiberlock’s RECON Smoke Odour Sealer it is critical that the substrate be thoroughly cleaned. Smoke odour encapsulation is a final step that needs to be part of a comprehensive smoke/odour management protocol. This protocol should include the following steps: odour cleaning, odour neutralisation, and odour encapsulation. Fiberlock recommends cleaning with RECON Heavy Duty Cleaner or Extreme Duty Cleaner, followed by the application of RECON Extreme Duty Odour Counteractant. After the substrate is clean, dry, and sound apply RECON Smoke Odour Sealer to encapsulate any residual odours that remain.
APPLICATION TOOLS
Apply RECON Smoke Odour Sealer with a brush or airless spray equipment.
- Brush: Synthetic, nylon, or polyester bristle
- Roller: Not recommended
- Spray Settings: Pressure: 2200-3000 P.S.I. Tips: .017 to .023 tips
PRODUCT APPLICATION
Apply RECON Smoke Odour Sealer generously and uniformly by brush or airless spray. A roller application is not recommended. Apply one coat of RECON Smoke Odour Sealer and ensure that the finished surface is properly sealed. To ensure that the finished surface is properly sealed, two coats may be required on some porous or heavily stained surfaces. Topcoat floor applications when foot traffic or heavy storage is expected. RECON Smoke Odour Sealer is tintable up to 2 oz. of universal liquid colorant per gallon. HVAC Application: RECON Smoke Odour Sealer can be used to encapsulate malodors within HVAC systems as part of fire damage restoration. This product can be used in both fiberglass-lined and unlined ductwork. Surfaces should be clean, dry, and sound prior to application. RECON Smoke and Odour Sealer meets the requirements of NFPA 90A/90B standard.
TOP COATING
Wait at least 24 hours prior to top coating @ 70 – 77°F, 50% R.H. Lightly sand and clean surface of Recon Smoke Odour Sealer prior to top coating. Do not topcoat Recon Smoke Odour Sealer with anything less than a quality 100% acrylic latex coating with an eggshell sheen or higher. Avoid enamel, alkyd, and oil-based paint topcoats. Test patch prior to application is recommended. Failure to follow these guidelines could result in cracking or “alligatoring” on certain substrates.
COVERAGE
- Smooth Surfaces: 200-400 ft2/gal.
- Porous Surfaces: 100-200 ft2/gal.
DRYING TIME
- @ 70°F 50% R.H
- To Touch: 30 Min.
- Recoat: 4 Hours
CLEANUP
Clean tools and drippings with warm soapy water before RECON Smoke Odour Sealer dries. Dispose of waste according to all existing local, state, and federal regulations.
PRECAUTIONS
Store in a dry place at temperatures between 50°F (10°C) and 90°F. (32°C). Stir thoroughly. Do not mix with any other coatings, solvents, or colours in oil. Do not apply when air or surface temperature is below 50°F, when drying conditions are poor or when surfaces are above a 15% moisture level content. Use adequate ventilation during application. When applying with a sprayer, wear a NIOSH-approved respirator with any R, P, N, or HE filter. For interior use only.
Safety & Technical Data Sheets
Technical data
From the Fiberlock product data sheet for Recon Smoke Odour Sealer (3091 clear and 3090 white). Imperial figures are the manufacturer's; the metric equivalents are ours.
- Solids by weight: 51.4% ±2%; by volume: 44.0% ±2%
- Viscosity: 75 Krebs units at 21 °C
- Gloss: 82° ±5 at 60°
- VOC: 68 g/L (white), 60 g/L (clear)
- Weight: 1.15 kg/L (9.6 lb/gal ±0.5)
- Flash point: non-combustible
- Shelf life: 36 months minimum in the original sealed container
Coverage
- Smooth surfaces: 4.9–7.4 m²/L (200–300 ft²/gal)
- Porous surfaces: 2.5–4.9 m²/L (100–200 ft²/gal)
Fire-damaged substrates sit at the porous end of that range. Charred timber and smoke-loaded plasterboard drink material — budget nearer 2.5 m²/L than 7.4.
Application
- Drying at 21–25 °C and 50% relative humidity: touch dry 30 minutes, recoat 4 hours, topcoat 24 hours
- Minimum application temperature: 12.8 °C
- In humid conditions, apply only when the surface temperature is 15.6 °C or above
- Airless spray: 0.017–0.023 inch tip at 152–207 bar (2,200–3,000 psi)
The 24-hour topcoat wait is the one that catches people out. Four hours to recoat with more sealer, but a full day before finish paint goes over it.
Independent test results
- ASTM E84 fire rating: Class A — flame spread 10, smoke developed 10
- ASTM C-411 heat rating; conforms to NFPA 90A and 90B
- Product label (18.9 L)
