Johnson Engineered Marble is essentially a mixture of natural minerals like calcite, combined with colour pigments, molded and baked with specially-blended polyester resin which acts as a binder. It is produced in the form of blocks and slabs of adequate thickness, and then sawed into tiles from the blocks. Johnson Engineered Quartz is manufactured through a process that combines natural quartz with a small volume of polyester resin and colour pigments, then baked to create a quartz slab of desired thickness. It is very hard and less porous than engineered marble.
If stored outside, Marble and Quartz slabs must be kept covered and be stored with the polished face unexposed. Full back support needs to be provided since prolonged storage may cause warping due to pressure
Due to inherent properties of engineered stone, they are not suitable for use in external areas which are directly exposed to sunlight. Our products are recommended for internal use only.
TopShield is highly resistant to heat. scratches and stains. However, exposure to excessive heat can possibly damage the surface. We recommend the use of hot pads to protect the surface from heated cookware.
Due to Its inherent nature, quartz countertops are extremely robust and highly scratch resistant. However, no countertop material is entirely scratch proof. We recommend that a cutting board be used when chopping vegetables and avoid using sharp objects directly on the surface.
Johnson TopShield has been treated with Johnson's patented Germguard technology making it highly resistant to microbial growth. The surface has been certified food-grade and is perfectly safe to prepare food. Besides, quartz is non-porous by its nature and is an ideal material for hygienic kitchen countertops.
