Concrete and Cement Based Surfacing

Concrete is a specialized countertop surfacing material. Molded into shape, it is seamless. Concrete can be dyed just about any color. Concrete countertops can be fabricated at the manufacturing facility or poured in place. Because it begins in the form of a slurry, concrete can be transformed into virtually any shape that becomes a solid mass. It can be polished, stamped, or stained. Objects can be embedded in it.

While it has a rougher appearance than granite or solid surfacing, with hairline cracks (called crazing) and surface imperfections, these qualities make it appealing to many. Like granite and other natural stone materials, upkeep is minimal, but it must be sealed to prevent stains.

Initially considered an artisan’s product, concrete countertops are widely available throughout North America today. An excellent resource for information about custom concrete countertops is Concrete Countertops: Design, Form and Finishes for the New Kitchen and Bath by Fu-Tung Cheng with Eric Olsen (Taunton Press, 2002) as well as the Web site www.concreteexchange.com.

Natural Stone Surfacing

Flagstone

Flagging is a process whereby stone is split into thin slabs suitable for paving, surfacing, and . Although generally identified as flagstone, bluestone and slate are the most common types of flagging stones used.

Granite

Polished and honed granite countertops are a popular element of upscale kitchens and bathrooms. A natural stone countertop conveys a sense of beauty and warmth that is combined with a durable work surface that can withstand the expected high use of the new space.

Granite begins as the liquid magma (hot molten stone) in the center of the earth. It is a type of stone called igneous. Due to extreme pressure within the earth and the absence of atmo- sphere, granite is formed very dense with no pores. Granite is really a host of ingredients including common minerals like feldspar, quartz, and mica. Feldspar is the major mineral component of granite, comprising 60 to 80 percent of the stone.

Granite is not as subject to staining as marble is because of an extremely low absorption rate. It also is less prone to scratching than marble. Its coarse grain also makes it more slip-resistant than marble.

Although granite is more appropriate than marble in a residential kitchen, it will be more serviceable if it is sealed. Many natural characteristics of the granite itself impact how porous the stone is, which determines if it should be sealed or not. However, most experts suggest initially sealing the granite when it is installed and resealing it every year or every two years.

Granite Coloration

Granites vary widely in shade, clarity, and movement of pattern. There will be variations from slab to slab because of mineral content and veining, which adds to the character of the natural stone. Therefore, most granite selections are made at the stone yard, allowing clients to reserve their stone slabs.

Limestone

Limestone is popular for its earthy tones and its variety of colors and characteristics. Even more easily stained and etched than marble, limestone is not a typical kitchen countertop choice, but it does wear well enough to be used on floors, backsplash areas, and bathroom surfaces. To decrease the material’s susceptibility to staining, it must be regularly sealed.

Limestone is the result of millions of years of seashells and bones of sea creatures settling as the sediment on an ocean floor. The calcium in the bones and shells combines with the carbon dioxide in the water to form calcium carbonate, which is the basic mineral structure of all limestone and marble. Less than 3 percent of the stone is the color, which are simply other natural elements present when the stone is formed. Given enough heat and pressure, limestone will crystallize, resulting in marble. Limestone that has not been crystallized will not be able to be polished and will be honed.

Marble

Marble and limestone begin as the same material. Given enough heat and pressure, limestone will crystallize, resulting in marble. The crystal structure allows marble to take a polish that brings out the color of the other trace elements. Italian marble is world renowned. Belgium, Spain, Greece, and France are also known for their marble quarries. Many U.S. quarries also produce beautiful marble slabs.

The patterns and color of marble are more varied than those of granite, and they create a softer appearance overall. Like granite, marble fits well in either contemporary or traditional settings . However, because marble is not as hard as granite, it is more subject to surface damage. Therefore, some experts rule out unsealed marble for use on kitchen countertops. If properly sealed, a marble surface can be used in an actively planned kitchen. It is important to note that different marbles vary in their hardness factor. Generally, the lighter the color of the marble, the more delicate it is. Others suggest using very hard marble to resist wear and honed marble to hide scratches. Unless the finish is etched, honed, or pummeled, marble is slippery when wet. Therefore, make sure your clients understand a polished marble floor will be slippery.

Numerous minerals are present that account for the markings and color range associated with marble. Marble is available in a wide color palette. Some marbles feature fluid directional patterns; others offer a general, overall design.

The more colorful and decorative the marble, the more fragile it is. Each vein in a stone is the result of natural discoloration from water. It is like a tiny fracture that, under pressure, can lead to breakage. Marble is rated according to an A‐B‐C‐D classification based on the fragil- ity of the stones. A and B marbles are solid and sound. C and D marbles are the most fragile but also the most colorful and decorative.

The grade of marble, rarity of the specific type of stone, and demand for the type of material affects pricing. Before specifying marble, advise the client about durability.

Marble is soft and porous. This means it stains easily if not initially sealed with at least two coats of a penetrating seal. In addition, it must be resealed frequently. White marble is softer and less dense than colored marble, so it is more easily stained. Dark marble shows scratches more easily.

Slate

Durable, elegant, and acid‐ and stain‐resistant, slate has a natural cleft, a split face, and a texture similar to split‐cedar shingles. New England slate is stronger than granite and marble because it is made of laminated stone. The wide range of colors includes hues that range from earth tones to reds. With its satiny, non-shiny surface, a slate countertop would blend well with matte finish cabinets in Shaker‐and Victorian‐style houses, where high‐gloss granite might be overwhelming. But beware: Tables and chairs may rock on the irregular cleft face of a slate floor.

Slate is a metamorphic rock formed from the low‐grade metamorphism of the sedimentary rock shale. Slate, like shale (mudstone), is a very fine‐grained rock of mostly microscopic quartz and calcite. Slate can also contain some of the same minerals found in granite, which makes some slate iridescent and/or hard. The alteration of shale by heat and pressure pro- duces the pronounced partings that give slate its layered characteristics. Like limestone and marble, the colors come from trace metals. The vivid colors on most Chinese and Indian slate are the result of splitting the slate along natural layers, which exposes the metals to the atmosphere and causes them to rust.

Unlike granite and marble, slate—because it is nonporous—does not require a penetrating sealer, but a clear surface wax gives slate a wet look and enhances its color. Although slate scratches easily, marks that do not come off with normal cleaning usually can be removed with steel wool.

Soapstone

Soapstone earns kudos as a countertop for its resistance to chemicals and its appealing matte, smooth finish. One disadvantage: The maximum length of a slab of soapstone is 4 to 6 feet (1 220 mm to 1 830 mm), whereas granite slabs measure from 8 to 12 feet (2 440 mm to 3 650 mm) long. As for flooring, a low supply of soapstone has kept prices too high for widespread use.

Unlike granite and marble, soapstone—because it is nonporous— does not require a pene- trating sealer. Treat soapstone with mineral oil monthly during the first year to speed the natural oxidation from light gray to a rich dark gray. After a year, clean with a standard household solution. Dents in soapstone can be feathered out with a block and sandpaper.

Terrazzo

An alternative to marble is terrazzo—a combination of marble, concrete, and cement that can be formed into a variety of configurations, such as a countertop with an integral sink. Terrazzo is a slurry mixture of stone chips consisting of marble and cement. This marble aggregate concrete produces a hard and durable flooring surface. It is also used as a wall treatment. It is available in field tiles of a more solid nature and decorative border tiles in various patterns and colors to match or contrast with the field tiles. Such a combination can provide a dramatic old‐world look.

Natural Stone Institute:

Travertine

Travertine begins as limestone, which, over time through geological shifting, has found its way deep in the earth. The porous nature of limestone makes it a great reservoir for liquids. Aquifers, which are enormous underground pools of water that feed our wells, were formed when the ice that covered much of the Earth melted. The water was absorbed by limestone. Heated by the earth’s inner core, the water rises as steam and hot pressurized water to form geysers. This rising hot water dissolves the limestone and brings with it granules from below, forming mud beds on the surface. If enough time transpired and the mud beds cool, they will crystallize into solid stone called travertine.

Quartzite

Quartzite is a decorative stone and may be used to cover walls, as roofing tiles, as flooring, and stairsteps. Its use for countertops in kitchens is expanding rapidly. It is harder and more resistant to stains than granite. Quartzite is a very hard rock composed predominantly of an interlocking mosaic of quartz crystals. The grainy, sandpaper-like surface is glassy in appearance. As quartzite is a form of silica, it is a possible cause for concern for fabrication workplaces and in homes. Cutting, grinding, chipping, sanding, drilling, and polishing natural and manufactured stone products can release hazardous levels of very small, crystalline silica dust particles into the air that workers breathe, and this is a known carcinogenic material.

Ceramic tile Surfaces

Ceramic tile counter surfaces are a popular choice for kitchens and bathrooms due to their durability, versatility, and aesthetic appeal. Here’s a detailed description of ceramic tile counter surfaces:

Composition and Manufacturing

Ceramic tiles are made from a mixture of natural clay, sand, and water, which is shaped and then fired at high temperatures in a kiln. This process hardens the tile and makes it durable. The tiles are often glazed, which involves adding a layer of liquid glass to the surface and then firing it again. This glaze can be colored or patterned and provides a hard, protective surface.

Types of Ceramic Tiles

  1. Glazed Ceramic Tiles: These tiles have a glass-like coating that provides color, patterns, and a high level of stain and water resistance.
  2. Unglazed Ceramic Tiles: These tiles are fired without a glaze, resulting in a more natural and rustic appearance. They are often used for a more traditional or earthy look but require sealing to prevent stains.
  3. Porcelain Tiles: A subtype of ceramic tile, porcelain is made from finer clay and fired at higher temperatures, making it denser, more durable, and more water-resistant than standard ceramic tiles.

cast Polymer & Synthetic Surfaces

Cast polymer synthetic surfaces are man-made materials designed to mimic the appearance and functionality of natural stone or other solid surfaces. These surfaces are typically used in countertops, sinks, bathtubs, and shower surrounds. Here’s a detailed description of cast polymer synthetic surfaces:

Composition & Manufacturing

Cast polymer surfaces are made from a mixture of polyester or acrylic resins, pigments, fillers, and a catalyst that initiates a chemical reaction to harden the material. Common fillers include marble dust, limestone, and other crushed stone materials. The mixture is poured into molds, which can be customized to any shape or size, and then cured at room temperature or in an oven to solidify.

Types of Cast Polymer Surfaces

  1. Cultured Marble: Made with a mixture of polyester resin and marble dust. It mimics the appearance of natural marble and is often used in bathroom vanities and countertops.
  2. Cultured Onyx: Similar to cultured marble but with a translucent appearance, giving it a more luxurious and unique look.
  3. Cultured Granite: Uses a blend of polyester resin and natural stone particles, resulting in a surface that closely resembles natural granite.
  4. Solid Surface: Made primarily from acrylic or polyester resins, solid surface materials are homogenous throughout, meaning the color and pattern are consistent throughout the thickness of the material. Brands like Corian and Avonite are well-known for solid surface products.

Properties and Benefits

  • Aesthetic Versatility: Cast polymer surfaces can be produced in a wide range of colors and patterns, many of which replicate the look of natural stone or other high-end materials.
  • Seamless Installation: Because they are poured into molds, cast polymer surfaces can be fabricated to fit exact dimensions and shapes, allowing for seamless installation with integrated sinks and backsplashes.

Laminate Surfaces

High-Pressure Decorative Laminates

High-pressure decorative laminates (HPL) typically are composed of three types of paper fused under heat and pressure into a single surface. The top coat is a melamine resin‐saturated overlay. The second sheet is the decorative paper, consisting of a melamine resin-saturated paper carrying either a surface color or a gravure print. Under these two levels is a core or body made up of three to nine sheets of phenolic resin-saturated Kraft paper.

The entire assembly is pressed at between 1,000 to 1,200 pounds (454 kg– 544.8 kg) per square inch for about one hour at temperatures exceeding 280° F (137.78° C).

High-pressure decorative laminates are divided into forming and non forming grades. Non- forming laminate is rigid, while forming laminate has been engineered to be more flexible so it can be bent under heat. This process is called post-forming.

The cabinet industry uses vertical-grade high-pressure decorative laminate that is 0.030 inch (0.75 mm) thick and may be formable. Countertop fabricators use a horizontal grade of high‐pressure decorative laminate that is .050 inch (1.2 mm) thick and is typically not formable. The post-forming countertop grade is 0.042 inch (1 mm) thick.High-pressure decorative laminates are used most frequently on countertop surfaces. They are also used by many cabinet manufacturers for door styles. High-pressure decorative laminates are generally applied to a particle board substrate. Green manufacturing processes now produce environmentally friendly substrates.

Of all the laminates available, high‐pressure decorative laminates offer the greatest impact resistance. They are available in a wide range of colors, patterns, textures, and finishes. Improved printing methods have created realistic stonelike patterns in laminate products. These surfaces can be textured to make their visual appearance even closer to natural stone. Some manufacturers offer special fire-resistant, abrasion-resistant, and chemical-resistant surfaces.

Generally, all high-pressure decorative laminates have excellent stain, abrasion, scuff, and wear resistance. However, because the laminate is applied on a substrate, if a chip occurs, it is not repairable. Smooth glossy finishes show scratches more easily than matte and textured. Solid colors typically show scratches more readily than pattern surfaces.

Natural Wood Surface Materials

Countertops are made from laminated or solid wood products. In addition to full counter- tops, insert blocks are often installed in the kitchen work surface.

The insert blocks are available in a variety of sizes and finishes. Both edge and end grain laminations are popular. In laminate countertops, an installation ring secures the wood section in place. A lip in the block can provide stability for a drop-in-place installation.

Some kitchens may feature the entire countertop in wood surfacing. When this type of countertop is planned, the designer must specify what type of wood will be used, what type of finish the block will have, and what water and heat protection the block will receive.

Natural Wood Surface Species

Several types of woods are available from different manufacturers:

Eastern Hard Rock Sugar Maple

This wood is considered the hardest; thus cutting or scratching damage will be minimized.

Western Maple; Western Alder

This wood is not as hard as eastern maple and will be more susceptible to wear through, cutting, or scratching.

Walnut; Cherry

Or other specialty hardwoods, these woods are sometimes specified in focal point areas that will not receive excessive use.

Grain patterns with the laminations will vary according to the fabrication procedure used. 

  • Full-length edge grain laminations feature long, unbroken strips of the wood laminated together. The edge widths remain constant.
  • Butt-joined edge grain laminations feature various strips within the overall length of the top. The edge widths remain constant.
  • End-grain laminations feature a checkerboard effect on small squares of wood.This Typeof fabrication is normally limited to counter inserts.

The wood tops may be finished in several ways. The intended use of the block should deter- mine the finish selection.

Unfinished Wood

The finish consists of oiling wood throughout the counter surface lifespan on a four- to six-week maintenance schedule. This method is most desirable if the entire counter surface will be wood and local fabrication of seams or miters is required. Prefinished tops hinder proper adhesion of seams and must be refinished if any sanding will be done.

Prefinished Wood

The factory finish includes a penetrating sealer and a nontoxic lacquer finish. The combination of sealer and varnish prevents moisture penetration. No oiling is necessary, and a damp cloth may be used to wipe the board clean. Chopping on the surface may not damage the finish. This type of finish is appropriate for countertop sections, such as island tops or sandwich centers.

A wood surface can also be used to differentiate the seating area from the solid surface work counter.

A section of an island countertop is finished in a rusticated wood with a coordinating wood support underneath it.

Wood Sealed with Polyurethane

Polyurethane sealer is used on unfinished wood tops that will not be used for chopping surfaces and will not come in contact with food. The finish is very good on tops that will be exposed to moisture and liquids.

Engineered Quartz Surfacing

Engineered quartz surfacing, often referred to simply as quartz countertops, is a popular and versatile material used in kitchen and bathroom countertops, as well as other applications in residential and commercial spaces. It is composed of approximately 90-95% crushed natural quartz crystals, combined with resins, polymers, and pigments.

The manufacturing process involves mixing the crushed quartz with a binder (usually polyester resin) and sometimes other additives to create a slurry. This mixture is then compacted under high pressure and subjected to intense heat, resulting in a dense, non-porous slab. The final product is exceptionally durable, resistant to scratches, stains, and heat, making it suitable for high-traffic areas in homes and businesses.

Engineered quartz offers a wide range of colors and patterns, often mimicking the appearance of natural stone like marble or granite. It provides a consistent and uniform look, without the natural variations found in quarried stones. Additionally, quartz countertops are relatively low-maintenance, requiring minimal upkeep compared to some other countertop materials.

Sintered STone Surfacing

Sintered stone surfacing is an innovative material that has gained popularity in kitchen and bathroom applications due to its exceptional durability, aesthetic versatility, and low maintenance requirements. Here’s a detailed description of sintered stone surfacing:

Composition and Manufacturing

Sintered stone is made from a blend of natural raw materials such as minerals and clays, including quartz, feldspar, and silica. The manufacturing process involves applying intense heat and pressure to these materials to form a compact, dense surface. This process, known as sintering, mimics the natural geological processes that form stone but in a much shorter time frame. The key steps include:

  1. Selection of Raw Materials: High-quality natural minerals are chosen for their properties.
  2. Blending and Mixing: The raw materials are finely ground and mixed to create a homogeneous blend.
  3. Forming and Pressing: The mixture is formed into slabs and subjected to extremely high pressure to compact the materials.
  4. Sintering: The slabs are then heated to temperatures exceeding 1200°C (2192°F), causing the particles to bond and create a solid, non-porous surface.
  5. Finishing: The slabs are cooled and can be polished, honed, or given various surface finishes to enhance their appearance and functionality.

Specialty Metals

Copper

Copper countertops bring warmth and character to a space. They develop a distinctive patina over time, giving them a unique, evolving appearance. Copper is naturally antimicrobial, which can be an advantage in environments where hygiene is a priority.

Zinc

Zinc countertops offer a softer, more malleable surface compared to stainless steel or copper. They develop a natural patina as they age, which can add character to the space. Zinc is also naturally antimicrobial and can contribute to a healthier living environment.

Aluminum

Aluminum countertops are lightweight and easy to work with, making them a versatile option for various design applications. They are also corrosion-resistant and low-maintenance, making them suitable for both indoor and outdoor use.

PaperStone

PaperStone is an innovative and eco-friendly material used for countertops and other architectural applications. It is composed of 100% post-consumer recycled paper, which is combined with a proprietary, non-toxic phenolic resin and natural pigments. The result is a dense, durable, and visually appealing surface that offers a sustainable alternative to traditional countertop materials.

The manufacturing process involves layering and compressing the recycled paper with the resin and pigments, followed by a curing process. This creates a solid, non-porous slab that is exceptionally resistant to scratches, stains, and moisture. PaperStone is also heat-resistant and can withstand the demands of everyday kitchen use.

One of the key advantages of PaperStone is its environmentally-friendly nature. By utilizing recycled materials and non-toxic binders, it helps divert waste from landfills and reduces the need for virgin resources. Additionally, it is certified by the Forest Stewardship Council (FSC), indicating that the paper used in its production comes from responsibly managed forests.

Design-wise, PaperStone offers a unique and textured appearance, with a range of colors and patterns available. Its warm, natural aesthetic can complement a variety of interior styles, from contemporary to rustic. The material can be easily machined and fabricated, allowing for customization to fit specific design requirements. It is an excellent choice for environmentally-conscious clients and designers seeking a distinctive, eco-friendly surface.
