Rock-hard, long-lasting patches – thanks to air-cure conversion
Composition hardens when exposed to open air, producing a rock-like surface that resists breakdown. The formulation is made to set to a hard finish rather than remaining flexible.
Cured repairs stay firm under the thermal stresses found in fireplaces and stoves, reducing the need for repeat touch-ups.
Reliable adhesion on mixed materials – with a formulation for bricks, stone and metal
Chemical bonding is effective on porous masonry and many metal surfaces, creating a strong interface with firebricks, blockwork, stone and clayware. Adhesion has been validated by user reports of secure, lasting bonds.
Patches remain in place through heating cycles, helping prevent leaks and protecting metal components from direct exposure.
