Clore Fabric & Wood Fire Retardant Spray – 2 Spray Bottles
Best for small to medium projects, this spray set is designed to help prevent flame spread on fabrics and wood. It meets NFPA 701 and ASTM E84 Class A standards and dries clear with no sticky residue. The dual spray bottles offer quick, repeated treatments for upholstery, curtains, and décor. Not ideal for very large structural wood jobs where a gallon application is required.
Clore Fabric & Wood Fire Retardant Spray – 1 Gallon Jug
Best for larger wood surfaces and drapery projects, this gallon-size option provides extensive coverage for lumber, décor, and textiles. It adheres to NFPA 701, CAL Fire Title 19, and ASTM E84 Class A standards and dries clear. Use when you need a long-lasting protective layer without altering appearance. A limitation is the higher upfront volume, which may be more than needed for small rooms.
Clore Fabric & Wood Fire Retardant Spray – Spray Bottle
Best for portable or on-the-go applications, this spray bottle is suited for small areas, curtains, and delicate finishes where precision matters. It carries the same Class A rating and clear-drying feature as larger bottles. Limitations include coverage area per spray and the need for multiple applications on bigger projects.
Flamecheck M-111 Fire Retardant Spray (Quart)
Best for textiles, draperies, stage props, and other fabric-based surfaces, this quart-size spray is non-toxic and designed to meet Class A on ASTM E-84. It’s a preferred option when fabric safety and odor control are priorities. A limitation is that it focuses on fabric and may require exterior sealing for wood surfaces to maximize longevity.
DRI-ONE Fire Retardant Spray Liquid Solution (1 Gallon)
Best for a broad range of materials including raw wood and textiles, this gallon provides NFPA 701 and ASTM E84 Class A protection. It bonds with materials and dries clear, enabling post-treatment painting or staining. Choose this if you need a versatile, ready-to-apply solution for mixed-material projects. A potential limitation is the need for even coverage on porous surfaces to avoid uneven protection.
Buying Guide
What to consider when selecting spray on fireproofing for wood
- Material compatibility: Determine whether you’re protecting wood, textiles, or both. Some formulas are optimized for fabric, others for wood surfaces.
- Coverage and size: For large projects, select gallons or multiple bottles. For small spaces, spray bottles are more convenient.
- Standards and safety: Look for NFPA 701, ASTM E84 Class A ratings, and CAL Fire compliance where applicable. Clear drying reduces residue on visible surfaces.
- Application practicality: Consider dry time, odor, and whether treatments can be recoated or stained after drying.
- Longevity and maintenance: Some products require reapplication after weather exposure or cleaning. Consider exterior sealing needs for outdoor wood.
- Non-toxicity: If interiors or occupied spaces are involved, non-toxic formulas reduce chemical exposure.
How to apply for best results
- Prepare the surface: Clean dust and debris before application; allow dry surfaces to be completely dry.
- Test area: Apply to a small, inconspicuous area first to confirm appearance and adhesion.
- Even coating: Use steady, even strokes; avoid oversaturation to prevent runs or pooling.
- Ventilation: Ensure good air circulation during application and curing times.
- Reapplication: Some projects may require a second coat for thorough protection.
Choosing by scenario
- Residential rooms with drapes and furniture: Clore 2-spray-bottle package or the gallon jug for larger coverage.
- Theatrical or stage setups: Flamecheck M-111 is designed for fabrics and textiles with a non-toxic profile.
- Workshop lumber and decor: DRI-ONE gallon solutions offer durable, versatile protection for wood surfaces.
