Understanding SILGRANIT Composite Technology
The secret behind this sink lies in its advanced 80 percent solid granite composition, which behaves much like natural stone combined with high-grade acrylic resins. Think of it like a reinforced architectural casting where the color and material are uniform throughout rather than merely sprayed on top. This dense molecular structure prevents liquids from soaking into the material, creating a hygienic barrier that naturally repels stains, resists sharp kitchen tools, and absorbs heavy impacts without cracking or chipping.
Installation Guide
Review the provided cutout template carefully and verify your 14-1/4 by 14-1/4 inch countertop opening before cutting.
Ensure your supporting cabinet meets the minimum 15-inch outside width requirement to allow proper clearance.
Apply a compatible silicone sealant around the perimeter flange during drop in installation for a watertight seal.
Connect your 3-1/2 inch drain assembly and plumbing trap securely, noting that the drain is sold separately.
Care & Maintenance
Daily Cleaning Wipe the sink surface regularly with a mild dish soap and warm water using a soft sponge.
Stain Prevention Rinse away coffee, tea, and red wine promptly to keep the non-porous granite looking spotless.
Hard Water Care Remove mineral deposits periodically using a vinegar-water solution and a non-abrasive cloth.
Scuff Removal Buff out minor marks or metal residue from cookware using a nylon cleaning pad and specialized granite cleaner.
Surface Protection Avoid using harsh chemical bleach or abrasive scouring powders to preserve the protective finish.
