Blanco Silgranit Sinks Buyer’s Guide

This section will cover general information about Silgranit sinks. After reading our buyer’s guide, you should be able to confidently decide if Silgranit will work for you.

What is Silgranit?

Silgranit is Blanco’s patented granite composite material. Made with 80% granite, Silgranit is incredibly tough without many of the drawbacks you’ll find in other types of kitchen sinks.

Silgranit is engineered to be beautiful, stain-resistant, durable, and affordable. Blanco has a number of Silgranit sink collections, making it easy to find a design that works in your kitchen.

Granite composite is lighter than cast iron or fireclay. Most Silgranit composite sinks are also quite affordable.

Silgranit is sometimes referred to as Silgranit II or Silgranit ParaDur. These names are simply the newer versions of the original Silgranit granite sink material.

What are Silgranit Sinks Made of?

Blanco’s Silgranit sinks are composed of 80% real granite sand and 20% high-strength binding agent. The result is a composite sink material that is incredibly hard, but not as brittle or heavy as natural stone.

The material is engineered to be antibacterial. A Silgranit sink will reduce the growth of unhealthy bacteria by 98% compared to a non-Silgranit sink.

Fun fact: Blanco holds seven patents for Silgranit.

Blanco Silgranit Colors

Silgranit is offered in a variety of modern colors designed to work with any kitchen.

Since Silgranit is a solid surface countertop, the color cannot be scraped off or worn through.

The color of a Silgranit sink will not fade in the sun.

Blanco Silgranit color samples

The current lineup of Silgranit colors includes:

  • Anthracite
  • Biscotti
  • Biscuit
  • Café Brown
  • Cinder
  • Concrete Gray
  • Metallic Gray
  • Truffle
  • White

Silgranit Sink Durability

Silgranit granite composite is very durable. It’s made of 80% real granite sand, which becomes as hard as a rock when combined with Blanco’s high-strength binder.

You don’t need to worry about utensils, pots, and pans scraping and scratching the bottom of a Silgranit composite sink. The material is engineered to be rugged and highly impact-resistant, so you won’t have to baby it.

A Silgranit sink is highly resistant to heat, chips, stains, and acidic foods–the biggest potential threats a kitchen sink can face.

Plus, Silgranit sinks are covered by Blanco’s lifetime warranty against defects in manufacturing and materials.

Silgranit Heat Resistance

Silgranit is highly resistant to heat. It can handle temperatures up to 530° F, which is higher than the temperatures most home kitchen can produce.

It’s perfectly OK to transfer hot items from the stove or oven into a Silgranit granite sink.

How to Clean a Blanco Silgranit Sink

Cleaning a Silgranit granite composite sink is easy: Simply use a non-abrasive household cleaner and a regular sponge or cloth.

Silgranit sinks can be cleaned using products like Palmolive dish soap, Bar Keeper’s Friend powder or liquid, Soft Scrub, Windex, etc.

Products containing bleach are OK, but never use straight bleach on a Silgranit sink. Avoid caustic cleaners, cleaners with ammonia, or alkaline products.

Silgranit Sink Staining

Silgranit is completely non-porous and will not stain. Even things like tea, coffee, wine, and pasta sauce won’t leave permanent stains.

Staining foods that are allowed to dry will be harder to remove. In these scenarios, you can use baking soda or a mild abrasive cleaner. You can also use a Magic Eraser Original and some water.

Gentle scouring pads are fine, but avoid using steel wool, wire brushes, or other aggressive cleaning tools.

For extra tough stains, soak the stain in a 50/50 mix of water and bleach for an hour.

Are Silgranit Sinks Noisy?

Running water and contact with dishes can be surprisingly noisy with stainless steel or ceramic sinks.

Granite composite is naturally sound-deadening and produces a lot less noise than many other sink materials.

Maintaining a Silgranit Sink

It’s recommended that you rinse and dry your Silgranit sink after each use.

In areas with hard water you may notice deposits where water dries. This will be more noticeable on darker-colored sinks.

Water deposits can be cleaned using Lime-A-Way or CLR.

Silgranit granite sinks never need to be re-finished, treated, or conditioned. Applying a thin coat of mineral oil can help restore a Silgranit sink to its original brilliance, but this isn’t required.

Silgranit Sink Chips, Cracks, and Repair

As tough as Blanco’s granite composite may be, it’s not 100% immune to chips or cracking under extreme abuse.

Reports of cracks and chips are very uncommon, but they’re not unheard of. In some cases, improper installation was to blame.

In the event of a small chip, repair kits are available. In some cases, the chip may not be all that noticeable since Silgranit is a solid surface.

Silgranit Sink Installation

Blanco’s granite composite sinks are as easy to install as any other type of kitchen sink.

A number of Silgranit models can be installed as an undermount sink or as a drop-in.

For undermount installations, it’s recommended to support the sink with wooden braces or a sink harness kit.

Silgranit Sink Problems

Silgranit sink reviews from customers are generally positive. However, only a very small percentage of users had issues or complaints.

  1. Negative reviews were related to damage from shipping, usually cracks
  2. We few a few reviews that claimed that their sinks stained. However, in most cases the user was able to remove the “stain” with vigorous cleaning or a Magic Eraser.

Blanco Lifetime Warranty

Blanco offers a lifetime warranty on all of their kitchen sinks.

The warranty does not cover damage due to excessive abuse, misuse, or incorrect installation.
