What is the heat resistance of Buddy Rhodes Vertical Mix? Can I use Vertical Mix to create a fire pit or fireplace?
Fully cured, Buddy Rhodes Vertical Mix has a useful temperature range of -40°F/-40°C to 200°F/93°C. Vertical Mix has excellent freeze/thaw resistance. Applying a sealer is recommended to further reduce water penetration and enhance durability in freeze/thaw environments.
Although Vertical Mix is flame rated, certified to E-84/Class A, the rules for heat resistance are generally the same as other Portland Cement based concrete materials.
If the concrete is rapidly exposed to heat above 93°C/200°F, the moisture trapped in the concrete may quickly expand and crack or spall the surface.
We do not recommend Vertical Mix for direct flame contact for extended periods for this reason.
