Cera Mastic is a refractory putty for patching/repairing/filling fissures, cracks, seams, and joints in ceramic materials. It contains no Refractory-Ceramic-Fiber (RCF) and it works well to fill defects in dense or porous surfaces exhibiting no sintering, shrinking, or cracking with thermal cycling.
The adhesion, strength, hardness, and toughness of Cera Mastic assure the long life of repaired areas. Easy to apply with a putty knife or trowel: apply, dry, and place into use with no cure needed. Cera Mastic is usable to 2,732°F in all environments.
