Setup and Installation
The BLANCO PRECIS sink is designed for undermount installation. A template is included with your sink to assist with accurate countertop cutout and placement. Detailed installation instructions are provided in the official installation manual, which can be found on the BLANCO website or through the provided documentation link.
Key Installation Steps:
- Countertop Preparation: Use the provided template to mark and cut the opening in your countertop. Ensure all edges are smooth and sealed according to countertop manufacturer recommendations.

Operating Instructions
Your BLANCO PRECIS SILGRANIT sink is designed for everyday kitchen tasks. Its robust construction allows for direct contact with hot items and provides resistance against scratches and stains.

- Scratch Resistance: The durable surface is highly resistant to scratches from cutlery and cookware.
- Stain Resistance: The non-porous surface repels common household stains, including those from coffee, tea, and red wine.
- Acid Resistance: The granite composite material is resistant to common kitchen acids, such as those found in citrus fruits.

Maintenance and Care
To maintain the appearance and performance of your BLANCO PRECIS SILGRANIT sink, follow these care guidelines:
- Daily Cleaning: Clean the sink regularly with a soft cloth or sponge and mild dish soap. Rinse thoroughly with water after cleaning.
- Stain Removal: For stubborn stains, use a non-abrasive cleaner specifically designed for granite composite sinks. Avoid harsh chemicals, abrasive pads, or steel wool, as these can damage the surface.
- Hygienic+Plus Surface Technology: The sink features an advanced surface technology that acts as a protective shield against liquids and dirt, making it highly hygienic and easy to clean.
- Preventing Water Spots: Wipe the sink dry after each use to prevent mineral deposits and water spots, especially in hard water areas.
- Avoid Strong Acids/Alkalines: While resistant to common kitchen acids, avoid prolonged contact with strong acids or alkaline solutions, as these may affect the finish over time.

Troubleshooting
Most issues with your BLANCO PRECIS sink can be resolved with simple steps.
- Stains: If a stain persists after regular cleaning, try a specialized granite composite sink cleaner. Ensure the cleaner is non-abrasive.
- Scratches: Minor surface marks are typically not true scratches due to the material's hardness. Often, these are metal marks from pots or pans, which can be removed with a non-abrasive cleaner and a soft scrub brush.
- Water Spots/Mineral Deposits: Use a solution of equal parts white vinegar and water to dissolve mineral deposits. Apply, let sit for a few minutes, then scrub gently and rinse thoroughly.
- Drainage Issues: Ensure the drain assembly is clear of debris. If the issue persists, check plumbing connections for blockages.
