Suitable Paints and Sealant Materials
3.2.12.5.1 Paint Types Approved for Use
Industrial Acrylic Paints, Alkyd based Paints. When selecting paint for applications on facings, mantels, corbels or floors within
2’ in front of a fireplace raised 6” or higher, avoid off the she lf paints which may have modifier additives used to increase
“hiding” ability, accelerate drying times and curing tim es. Consult with a reputable paints and sealants supplier and acquire
industrial acrylic paints or alkyd-based paints.
3.2.12.5.2 Sealants Type Approved for Use
Heat resistant polyurethane sealants which are not damaged by prolonged exposure to raised temperatures. Many are flame
resistant, meaning that they resist ignition when exposed to high temperatures and can insulate the substrate and delay
damage to it. When selecting polyurethane for applications on facings, mantels, corbels or floors within
3’ in front of or above a
fireplace, avoid off the shelf urethane sealants which may have modifier additives used to accelerate drying times and curing
times. Consult with a reputable paints and sealants supplier and acquire heat resistant polyurethane sealants.
3.2.12.5.3 Wood Application Cautions
If wood used around or in front of the fireplace has been chemically cleaned or bleached prior to staining or painting, it is of the
utmost importance to make certain that the cleaner or bleach does not remain in the wood substrate under the final paint or
sealant applied. If any cleaner or bleach remain within the wood structure, application of heat from the fireplace, even low-level
heat, will cause the cleaner or bleach compounds to expand or evaporate causing separation of the paint or sealant from the
wood surface and may cause peeling or bubbling of the paint or sealant.
Moisture content of the wood substrate is also of critical importance. High moisture content wood when heated will yield
evaporation of the moisture and hydraulic pressure under the paint or sealants which can lead to peeling or bubbling. Always
select the lowest moisture content wood substrate.
