Refractory Mortars
Refractory mortars are used for laying and repairing linings of furnaces, fireplaces, and industrial units, ensuring strong joints between refractory bricks and blocks. We offer a wide selection of mortars — including fireclay, high-alumina, mullite, and specialized formulations tailored to different operating conditions. Our mortars are easy to apply, provide excellent adhesion, and deliver high resistance to extreme temperatures and aggressive environments, extending the service life of refractory constructions.
