TimberClear + Top Coat

Fireshield TimberClear is a clear, waterborne, halogen-free intumescent basecoat for use on interior timber-based substrates. A sealer coat of Fireshield® Top Coat Matt or Semi-gloss must be applied to complete the fire protection system.

When exposed to high temperatures derived from flames or intensive heat radiation from fire, the TimberClear system forms a thick layer of porous foam that extinguishes the flow of heat to the treated surface.

It should be spray applied for best results, brush and roller is only advised for small areas or for touch up. The Maintenance Guide and Application Instructions are available upon request from Fireshield.
