Limitations - Stained, Varnished or Painted Wood

• For treatment with Thermoproof to be effective, it needs to be able to penetrate the wood.

• To fire protect painted wood, see Thermoguard Timbercoat.
• To fire protect clear normal varnished wood, use Thermoguard Fire Varnish Basecoat & Thermoguard Fire Varnish Overcoat.
• To fire protect external stained varnished, woodstained or other coated wood, contact Technical Dept.

The new BS EN tests also monitor -

• Smoke & Gas “s” – s1 + s2 are none or very low & compliant levels, s3 = moderate , s4 = heavy smoke.
• Flaming Droplets or Airborne particulates – dO is none, d1 = low, d2 = moderate, d3 = high levels.
