Dek Gard Wood Stain and Paint Fire Retardant Additive

Turn your favorite exterior or interior wood finishes into a high-performance fire barrier with Dek Gard Wood Stain and Paint Fire Retardant Additive. Engineered for professional applicators and DIYers alike, this advanced, highly concentrated powder blend mixes directly into your existing coatings to deliver certified flame retardancy without altering the final look of your project. It is the ultimate choice for enhancing the safety of outdoor decks, siding, fences, and structural timbers.

Why Use Dek Gard Additive?

Traditional fire retardants often leave a cloudy residue or restrict you to standard colors. Dek Gard changes the game. By blending seamlessly into your chosen topcoat, it ensures your wood grains remain beautiful while building a reactive shield against flame spread.

  • Broad Product Compatibility: Optimally formulated to mix easily into water-based, acrylic, and latex wood stains, sealers, clear coats, and exterior paints.

  • Reactive Intumescent Technology: When exposed to extreme heat or direct flame, the treated coating reacts chemically, producing a dense char layer that starves the fire of oxygen and slows thermal transfer to the wood.

  • Preserves Aesthetic Design: Dries completely clear in transparent stains and maintains exact color matching in solid paints—retaining your chosen exterior or interior design perfectly.

  • Weather & UV Resistant: Unlike surface-applied sprays that wash away, Dek Gard is locked inside the cured paint or stain film, providing long-lasting, heavy-duty defense against the elements.

Easy Application & Code Compliance

Simply pour the pre-measured Dek Gard concentrated additive into your paint or stain bucket, mix thoroughly with a mechanical drill paddle, and apply using a standard brush, roller, or airless sprayer. It helps treated lumber meet strict local building codes and fire marshal requirements for flame spread ratings.

Upgrade your finishes. Don’t compromise design for safety. Add Dek Gard Fire Retardant Additive to your next wood sealing project to secure verified, hidden protection.

FAQ

Questions before you order?

What is Flamex PF-2 used for?

Flamex PF-2 is a fire-retardant treatment for exterior wood, wood mulch, straw, and thatch.

How quickly should I order?

If the project is tied to an inspection, construction milestone, or installation date, request pricing and availability before scheduling the application. That avoids relying on unverified lead times.

How do I apply Flamex PF-2?

For optimal results, proper application is essential. Follow these guidelines to ensure maximum surface protection:

  1. Surface Preparation: The wood must be clean, dry, and free of existing stains, paints, or sealants that would block absorption.
  2. Method of Application: Use a low-pressure sprayer, brush, or roller to apply the product uniformly.
  3. Saturation: Ensure the wood reaches full saturation, normally 3-4 passes, making sure each pass penetrates before applying the next one (wet-on-wet application).
  4. Curing: Allow the product to dry completely—typically 24 to 48 hours—before exposing the surface to heavy moisture or foot traffic.
