For unfinished, absorbent wood, choose a fire-retardant treatment whose stated use and test information match the project. Master FX is a strong fit when buyers want listed ASTM E84 results for treated wood; DRI-ONE is available in both a five-gallon pail and a smaller kit. Clore is an interior-use option, while ForceField is primarily described for fabrics rather than timber. These treatments are not interchangeable with building-code approval or a substitute for fire-safety planning.

Master FX Master Flame Class A

Master FX Master Flame is a one-gallon fire-retardant spray for unfinished wood and other absorbent materials. Its product information reports SGS ASTM E84 testing on treated wood, with a Flame Spread Index of 15 and Smoke Developed value of 55, described as Class I/A performance. It creates a clear, dry barrier intended to limit flame spread.
Best for: Buyers treating porous, unfinished timber who want product information that specifically reports wood test results. It is also listed for paper, cotton, and fabric furnishings, making it relevant to projects involving several absorbent materials.
Important limitation: The listed use excludes painted, sealed, waterproof, polymer, nylon, silk, and other nonabsorbent surfaces. The product therefore may not suit finished lumber or coated wood. Check the label and project requirements before application.
Clore Fabric & Wood Fire Retardant

Clore is a one-gallon treatment presented for fabric and wood. The listing says it meets NFPA 701, CAL Fire Title 19, and ASTM E84 standards and is Class A rated. It is described as drying clear without sticky residue, details that may matter when treating visible interior surfaces.
Best for: Buyers looking for a treatment identified for both wood and fabric in interior applications. The multiple listed standards may be useful when comparing products, but users should verify that the specific standard and treatment are accepted for their intended project.
Important limitation: The product title specifies interior use only. Do not assume it is appropriate for outdoor timber, and confirm the required preparation and application instructions on the product label.
DRI-ONE Fire Retardant, Five-Gallon Pail

This five-gallon DRI-ONE option is described for natural textiles, raw wood, and other absorbent materials. The listing says the solution is ready to use without dilution, dries clear, and can be applied by spray, brush, or dip. It also says the treated material can be ready for paint or stain after application; follow the manufacturer’s instructions for timing and preparation.
Best for: Buyers with a larger treatment area or multiple raw-wood items to address. The five-gallon format and several listed application methods make it a practical option to compare for projects that need more product than a small container provides.
Important limitation: The listing describes use on raw wood and absorbent materials, not sealed or nonporous timber. It does not provide a specific coverage rate in the supplied product details, so estimate project needs using the label rather than assuming a treated area.
DRI-ONE 160-Ounce Kit With Sprayer

This DRI-ONE package contains one gallon, one quart, and one sprayer. Like the larger pail, it is described for natural textiles, raw wood, and absorbent materials. The product information says it requires no dilution, dries clear, and may be applied by spray, brush, or dip. It also states that the treated material can be painted or stained afterward.
Best for: Buyers who want a ready-to-apply kit for a smaller project or who value having a sprayer included. The one-gallon and one-quart containers provide a different package format from the five-gallon pail, which may be easier to manage for limited work.
Important limitation: Its stated timber use is raw wood. Buyers treating painted, sealed, or waterproofed surfaces should not assume the product will work on them; confirm suitability before application.
ForceField FireGuard 22-Ounce Spray

ForceField FireGuard is a 22-ounce flame-retardant and protection product. Its listed uses emphasize drapes, clothing, furniture, and fabrics. The product information says it helps prevent fire spread and minimize smoke development, and that it is designed for water-safe fabrics that have not been waterproofed.
Best for: Buyers addressing fabric furnishings alongside a timber project, rather than shoppers seeking a primary wood treatment. It is included here as a comparison point because it is a fire-retardant product, but its listed material focus differs from the raw-wood options above.
Important limitation: The provided product details do not identify timber as an intended surface. Do not select it for wood treatment unless the product label or manufacturer confirms that use. It is also not intended for fabrics that have been waterproofed.
Buying Guide: How to Choose a Fire Retardant Timber Treatment
Fire-retardant treatments are products intended to reduce flame spread or improve a material’s fire performance when used as directed. They do not make timber fireproof. The correct choice depends on the wood’s surface, the project location, the applicable requirements, and the manufacturer’s application instructions.
Is the timber raw, unfinished, or sealed?
Start by identifying the wood’s current finish. Some products here specifically describe use on unfinished or raw wood and absorbent materials. A sealant, paint, stain, waterproofing treatment, or other coating can change whether a liquid treatment can reach and bond with the wood. Do not assume a product suitable for raw timber will perform on coated lumber.
For finished wood, check the label or ask the manufacturer whether the surface is eligible. If the product information excludes nonabsorbent materials, treat that as a meaningful restriction rather than a minor preference.
What do the test standards tell you?
Compare the standards and test results actually stated for each product. Master FX lists SGS ASTM E84 results for treated wood, including a Flame Spread Index of 15 and Smoke Developed value of 55. Clore lists NFPA 701, CAL Fire Title 19, and ASTM E84. DRI-ONE describes Class A and references NFPA 701 and ASTM E84 in its product title.
Standards do not automatically establish that a product is accepted for every building, occupancy, or application. Confirm the exact requirement with the local building department, fire official, project designer, or other responsible authority. Ask whether the cited test applies to the material and use in question.
How much treatment do you need?
Container size can help narrow the choices, but it does not establish coverage. The listed options include one-gallon products, a 160-ounce kit containing one gallon and one quart, a five-gallon pail, and a 22-ounce fabric-focused spray. Use the label’s coverage guidance to estimate quantity because treated area can depend on the surface and application method.
A larger container may make sense for a broad project, while a smaller kit may be easier to handle for a limited task. Avoid buying based only on volume if the treatment is not confirmed for the wood or finish you have.
Which application method suits the project?
DRI-ONE states that its solution can be applied by spray, brush, or dip and does not require dilution. Other products are presented as sprays. Consider whether the item can be evenly treated with the method allowed by its label, and plan for the application conditions and drying instructions stated by the manufacturer.
Do not improvise a mixing ratio or application rate. If a product requires preparation, drying time, or a particular number of coats, follow the package directions. The supplied product descriptions do not establish one universal method for all timber treatments.
Will the treatment change the appearance of the wood?
Several listings describe their treatment as drying clear. That wording does not guarantee identical results on every species, finish, or condition of wood. Test the product on a small, inconspicuous area when the manufacturer’s directions allow, especially if the timber will remain visible.
DRI-ONE says the treated material can be ready for paint or stain after application. Follow its specific instructions before adding a finish. Do not infer that every product in this comparison is paintable or stainable.
Is the product for indoor or outdoor use?
Clore is identified as interior-use only, so it is not the appropriate choice when the project requires an exterior treatment unless the manufacturer confirms otherwise. For other products, do not assume outdoor suitability if the listing does not clearly state it. Weather exposure, moisture, and later surface coatings can affect whether a treatment remains suitable.
What should buyers verify before purchasing?
- Confirm that the product is specifically intended for the timber and surface condition.
- Check whether the stated standard or test matches the project’s requirement.
- Read instructions for preparation, coverage, application, drying, and any reapplication.
- Verify interior or exterior suitability rather than assuming it.
- Ask the relevant building or fire official whether the treatment is acceptable for the project.
- Do not treat a fire-retardant product as a replacement for required fire protection or safe building practices.
Frequently Asked Questions
Does fire-retardant timber treatment make wood fireproof?
No. These products are described as helping limit flame spread or improve fire performance. They should not be understood as making timber fireproof. Use the product as directed and follow applicable fire-safety requirements.
Can fire-retardant spray be applied to painted or sealed wood?
It depends on the product. Master FX excludes painted, sealed, waterproof, and other nonabsorbent surfaces in its listed directions. DRI-ONE describes use on raw wood. Check the specific label before treating finished timber.
Which listed product gives test results for treated wood?
Master FX reports SGS ASTM E84 testing on treated wood, with a Flame Spread Index of 15 and Smoke Developed value of 55. Confirm with the manufacturer and relevant authority whether those results meet the needs of a particular project.
Can these treatments be used outdoors?
Do not assume so. Clore is labeled for interior use only, and the supplied details do not establish outdoor suitability for every other product. Verify the product’s exterior-use instructions before applying it outdoors.
Can I paint or stain treated timber?
DRI-ONE says its treated material is ready for paint or stain after application. Follow the product’s directions for preparation and timing. The other listed products do not provide the same paint-or-stain information in the supplied details.
Is a fabric fire-retardant spray suitable for wood?
Not necessarily. ForceField FireGuard’s listed uses focus on fabrics, clothing, drapes, and furniture, and do not identify timber as an intended surface. Choose a product that explicitly lists the wood type and surface condition being treated.
