Surface Preparation

All surfaces must be free of oil, grease, dirt, corrosives or other contaminants before application. Porous metal castings should be baked at high temperature to burn off embedded oils. Smooth metal surfaces should be abrasive blasted with a coarse media to a minimum SP-10 near white blast (0.001” minimum profile) for best results.


All products should be mixed thoroughly to a uniform consistency prior to use. Product viscosities may be reduced by adding a maximum of 5–10% by weight of the appropriate thinner.  



Pyro-Putty® products may be applied using a spatula, putty knife or caulk gun. For cross-sections greater than 1⁄8”–1⁄4” multiple applications should be made to avoid blistering. Cross-sections for all products should not exceed 1⁄2”–3⁄4” (3⁄8” maximum for Pyro-Putty® 2400).


The following instructions are guidelines for curing. Alternative cure times may be appropriate depending on the size of
the application.

Air dry at room temperature for a minimum of 5–7 hours, longer for thick cross-sections.

A heat cure is not required if the use temperature exceeds 200 °c. Otherwise, heat cure at 95 °c for 3 hours.


Unopened containers have a six month shelf life when stored at room temperature. Make sure opened containers are capped securely to prevent evaporation. Place a plastic film in between the cap and container to prevent air leakage.
