Typically quarries will cut and ship slabs in measurements of 2cm or 3cm. In some cases, harder stones such as granite or quartzite will even be available in 1cm. But what should you do if you find your perfect stone but it is only available in 3cm and your project calls for 2cm? Luckily, there is a way for your fabricator to downsize your stone to fit your needs.

How does a fabricator transform a 3cm slab into a 2cm slab?

Most fabricators will have the ability to transform your 3cm slab into a 2cm slab using a mill saw. A foam board is placed on top of the work table to support the stone and absorb the pressure that the saw places on the stone to avoid creating cracks or fissures. The mill saw then moves across the surface, slowly grinding down the stone to 2cm.

What are some applications that may call specifically for a 2cm material?

Milling stone to from 3cm to 2cm is often the case for creating backsplashes. In some cases, a 3cm slab is too thick and may get in the way of the faucets.

Wall Applications

It is not recommended to use 3cm materials for wall applications since the typical household wall was not built to support this amount of weight. When applied to a wall the slenderness of a 2cm slab may be more visually appealing and easier to work with when installing electrical sockets or finishing the sides of the stone.

Does milling effect the strength of the stone?

Every countertop is just as good as the support underneath it. As a rule of thumb, 2cm is an appropriate strength for marble, quartzite, and granite.

Creating a slab smaller than 2cm (especially for marble) is not recommended unless it is for a smaller project such as a small vanity, threshold, or backsplash. If needed, quartzite and granite can be milled to about 1/2 an inch and for marble, it is not recommended to go below 3/4 of an inch in order to keep the integrity of the stone in tact.
