Pyromescent is a white, one-part, water-based fire proofing coating similar in appearance to ordinary dense paint film. As a “passive fire protection” coating, upon exposure to flame or heat, it immediately expands (intumesces) providing an effective, non-combustible insulation foam and heat shield to protect the subsurface. Pyromescent also cures to a durable, mold-resistant coating for the long-lasting protection of the coating film*.

*Treated Articles Exemption - This product contains an EPA registered antimicrobial to protect the coating from non-public health fungi and odor causing bacteria. No public health claims are being made.

Pyromescent is formulated as a ready- to-use coating and should not be diluted. It can be applied with a brush, roller or airless sprayer to obtain an even finish. Do not apply past the point of run- off. A cross-hatching technique is the best way to ensure sufficient wet/dry film thickness and complete coverage.
During Build-back:
Scrape the used Pyromescent from all surfaces. Clean surfaces with a low concentration of Grease Gobbler. Prime surfaces before re-painting with Pyromescent.
