Sold by the full gallon, Roscoflamex W40 effectively flameproofs untreated wood, plywood, cellulose board, acoustical board, and corrugated paper. This ready-to-use clear liquid is easily applied by immersion, spraying, or brushing to penetrate the surface of the material without changing its properties. In addition to flameproofing, Roscoflamex W40 also seals and protects the wood that has been treated. Roscoflamex W40 will not change the color of the wood, however, flameproofing may raise the grain slightly. This can be corrected by sanding very lightly.
How to apply Roscoflamex W40
Roscoflamex W40 is intended for use on untreated wood surfaces. No other coating (paint, clear acrylic, polyurethane, stain, etc.) should be applied on top of Roscoflamex W40. While a paint coating will not diminish the effectiveness of the W40, some paint and coatings may not adhere properly. If the wood is to be painted, test accordingly. Also, some coatings may be flammable when dry. Roscoflamex W40 will only treat the substrate and provides no protection against the possible fire hazard created by a flammable coating applied on top of the treated wood. Consider using Roscoflamex P50 as an additive when painting with Roscopaint. Penetrating stains will not alter the effectiveness of the W40. Do not use water-based clear urethanes or clear acrylics over W40 as clouding may occur.
DILUTION:
Roscoflamex W40 is used straight out of the bottle. DO NOT DILUTE .
APPLICATION:

* Brushing: Brush on three coats of warm W40 to both sides of wood. Apply enough solution to ensure that the material is wet. Allow at least 5 minutes between coats. Clean brushes thoroughly after use.
* Spraying: Spray 3 coats of warm Roscoflamex W40 uniformly to both sides of wood using a Hudson-type sprayer. Allow at least 15 minutes between coats. Clean sprayer thoroughly after use.

W40 Quick Tips
1. W40 is intended as a solution to flame retarding raw wood. Paints and sealers may be applied on top but special considerations must be taken for adequate adhesion over the W40. Also, avoid using water based clear sealers on top of W40 as clouding may occur.
2. Hay can be effectively treated with W40. However, it is necessary to insure that all strands of hay have been treated. As it is often not practical to immerse full bales, it is recommended that bales be separated into smaller sections, immersed and treated individually and then assembled back into bale form.
3. Live trees or plants, especially Christmas trees or wreaths cannot be treated with W40. Contact Rosco for more information or technical support on treating your scenery for flame retardance. |
