SPFR100 is designed for a wide range of absorbent timber and wood-based materials. Its transparent, water-based formulation penetrates the substrate and helps preserve the natural appearance of timber.
Its published EuroClass B-s1,d0 reaction-to-fire classification under EN 13501-1 applies within the tested and certified configuration defined in the classification documents. Project suitability should be verified for the intended substrate and end-use configuration.
Fire-safety requirements for timber depend on the building, intended use and end-use configuration. Selecting a fire-retardant treatment therefore requires clear classification documents, defined application parameters and verification against the project fire strategy. SPFR100 combines a transparent finish with published technical documentation for specification and project assessment.
The product has been tested at the independent laboratories MEKA (Latvia, NB 2040) and RISE (Sweden), and certified by Inspecta Estonia OÜ (Kiwa).
Preserves the wood's natural look and stays visually transparent - no whitish coating forms on the surface.
Published B-s1,d0 classification under EN 13501-1 within the tested and certified configuration defined in K16/2024 and ET-0388-24.
Solvent-free and formaldehyde-free according to the current technical and safety documentation. M1 emission classification 5096.
Designed for a wide range of absorbent timber and wood-based materials. Suitability must be confirmed for the intended substrate and end-use configuration.
Brush, roller or spray. Typically 2–3 coats, consumption 210–250 ml/m².
Can be tinted to most achievable shades while preserving a translucent (see-through) finish.
SPFR100 is available in a formulation designed for exterior timber exposed to changing weather conditions. Exterior performance depends on the substrate, application quality, construction detailing, exposure, inspection and maintenance. Follow the current Technical Data Sheet and maintenance guide. SPFR100 does not currently claim an EN 16755 EXT durability classification.

SPFR100 is a transparent, water-based fire-retardant impregnation for absorbent timber and wood-based materials. It penetrates the substrate and helps preserve the natural appearance of the wood, with a published EuroClass B-s1,d0 reaction-to-fire classification under EN 13501-1 and an M1 emission classification.
No. SPFR100 is a transparent impregnation, not an intumescent coating. It does not form a thick foaming layer or an opaque paint film; the natural grain of the timber remains visible.
The published B-s1,d0 classification applies within the tested and certified configuration defined in K16/2024 and ET-0388-24. Other substrates or end-use configurations require project-specific verification.
Yes. SPFR100 is available in a formulation designed for exterior timber exposed to changing weather conditions. Exterior performance depends on the substrate, application, detailing, exposure and maintenance. SPFR100 does not currently claim an EN 16755 EXT durability classification.
