Typhoon Bordeaux Granite: Fabricating Brazil's Flowing Stone

Typhoon Bordeaux is one of those slabs that sells itself in the showroom and then asks a lot of the shop. It is a Brazilian stone sold under the commercial granite label, and distributors describe it as a cream to pale gold base swept with waves of burgundy, brick red, mahogany and charcoal grey. You will also see it listed as Siena or Sienna Bordeaux. The movement is the selling point: nothing about the pattern sits still, and two slabs from the same block can read very differently from one end to the other. That beauty comes with fissures, resin treatment and a pattern that punishes careless layout.

This guide is written for fabricators, installers and designers who have a Typhoon Bordeaux job on the board and want to get it from the rack to the cabinets without surprises. We cover what the stone actually is in trade terms, how to inspect and lay out slabs with strong directional movement, what to expect from the saw and the cutouts, how to deal with resin-filled fissures, how to polish edges so the resin and the stone finish together, and what to tell the homeowner about sealing and daily care. Where published numbers exist and agree, we give them. Where they do not, we stay with practical shop guidance instead of guessing.

What Typhoon Bordeaux Is and Why the Label Matters

Start with the name. In the stone trade, granite is a commercial category, not a strict geological one. The Natural Stone Institute notes that many rocks that are not granite in the scientific sense, including gneiss, are grouped with granite because they perform similarly. Geology references make the same point and add that banded metamorphic stones are among the most common countertop granites. Typhoon Bordeaux's flowing, wave-like banding is the kind of texture usually associated with that metamorphic group rather than with an even, salt-and-pepper igneous granite. We have not found published petrographic data for this specific material, so treat that as a reading of the pattern, not a lab result.

Why should a fabricator care whether a slab is a textbook granite or a banded stone in granite clothing? Because banding changes behavior. A stone with layers of different minerals has planes where hardness, grain size and porosity shift. The darker burgundy and charcoal waves and the lighter cream base do not always cut, polish or absorb liquids at the same rate. Fissures tend to follow the grain of the pattern. When you know you are working a directional material, you plan cuts, cutouts and seams around those planes instead of treating the slab like a uniform sheet.

The supply side is fairly consistent. Distributors including Arizona Tile, MSI listings and UK importers list Typhoon Bordeaux as a Brazilian granite, offered in 2 cm and 3 cm thicknesses, with polished as the standard stocked finish. Some suppliers also list honed or leathered options, but availability varies by importer and by lot. Slab dimensions vary by block and distributor, so measure the actual slabs you are assigned rather than working from a catalog number. Arizona Tile also notes that its slabs show noticeable variation in color and movement and recommends viewing a range of pieces before purchase.

The other point distributors are open about is resin. Arizona Tile states that epoxy resin is applied during polishing to fill natural pits, cracks and fissures, and that some very small pits may reopen during later finishing. The Natural Stone Institute's sealing statement also refers to resin-treated granite slabs as a normal category of material. In practice that means every Typhoon Bordeaux slab you receive has already been through a factory resin line. Your job is to understand where that resin sits, avoid cutting it in ways that expose weak spots, and refill and polish anything that opens up during fabrication.

Finally, the safety baseline does not change because the stone is pretty. Cutting, grinding and polishing granite releases respirable crystalline silica. OSHA's permissible exposure limit is 50 µg/m³ as an 8-hour time-weighted average, with an action level of 25 µg/m³. Wet cutting, local water feed on hand tools, good housekeeping and appropriate respiratory protection are the standard controls. A stone with a lot of edge work and resin repair puts more time on hand tools, so plan dust control for the finishing bench, not just the saw.

Fabricating Typhoon Bordeaux Step by Step

Most shops follow the same order: inspect, lay out, saw, cut out, repair, polish and seal. On a slab like this, each stage feeds the next, so a layout shortcut becomes a resin problem later.

Slab inspection under raking light

Before a single template goes down, stand the slab up and inspect both faces with a bright light held low and to the side. Raking light shows what overhead shop lights hide: hairline fissures, shallow resin pools, pits that were filled but not fully leveled, and areas where resin has a slightly different sheen from the stone. Mark every fissure on the face with a wax pencil or tape, and photograph the slab with the marks in place. Check the back too. A fissure that is open on the back and resin-capped on the face is common in heavily figured stone, and that is exactly where an overhang or a narrow strip should not go.

Layout for directional movement

Typhoon Bordeaux has direction. The waves run one way across the slab, and the eye follows them. Decide with the customer which way the movement should flow on each run, then hold that decision on every piece. On an L-shaped kitchen, rotating one leg ninety degrees to save material will put the waves at a right angle to the other leg, and the seam will look like a mistake. Ask whether your slabs are sequenced, and use digital layout or full-size photos over templates so the pattern reads as continuous.

Layout is also where you protect the stone. Keep sink and cooktop cutouts away from marked fissures where you can, and avoid placing narrow sections such as the strips in front of and behind a sink directly across an open fissure. Those strips carry most of the handling stress during transport and install. If a fissure has to sit in a strip, make sure it is fully filled and consider reinforcing the strip per your shop's standard practice. Overhangs deserve the same attention. A fissure running perpendicular to an unsupported edge is a crack waiting for a heavy pot or someone sitting on the island.

Sawing and cutouts

On the bridge saw, Typhoon Bordeaux is generally handled with standard granite tooling. Use a blade matched to your saw and to the hardness of the stone, keep water flow steady and full across the cut, and let the blade work at a feed rate it can sustain without glazing. Watch the cut where the dark bands meet the light base. Changes in mineral content across the kerf can cause small chips along the top edge. If chipping starts, slow the feed and check the blade before blaming the stone. A blade that has started to glaze tends to chip any stone with mixed hardness.

Cutouts are where fissured stone fails most often. Use generous inside corner radii rather than sharp square corners, because square corners concentrate stress and give a crack a starting point. Drill corner holes with wet core bits before connecting them with the saw or a contour blade, and keep the slab fully supported on the table so the drop does not snap free and take the edge with it. Where your shop rods sink strips, follow the same practice here. Handle the cut pieces with the face supported, not by the narrow strips.

Resin repair of fissures and pits

Expect to do some resin work on every Typhoon Bordeaux job. After cutting, clean any fissures that opened or that run out to an edge. Blow out slurry, let the area dry completely and wipe with a solvent your adhesive manufacturer approves. Water trapped in a fissure under resin will cloud the fill and weaken the bond. A clear knife-grade epoxy is the usual choice for fissures because it can be worked into the crack and leveled with a blade, and it polishes cleanly. For wider fills in the dark waves, a pigment made for your adhesive system can help the repair disappear.

Apply resin slightly proud of the surface, give it full cure per the product data sheet, and only then grind it flush. Grinding resin before it has cured smears it into the surrounding stone and leaves a haze that will not polish out. On a stone with a cream base, test color first on an offcut. A fill that looks right when wet can dry darker or lighter. Keep track of where you put resin so the polisher knows those areas will need an extra pass at the finishing grits.

Edge polishing so resin and stone finish together

Run your normal granite pad sequence on the edges, wet or dry depending on your shop setup, and do not skip grits. Resin is softer than the minerals around it and will polish faster, while the hardest bands in the stone will polish slower. If you jump grits, the resin and the softer minerals can end up glossy while the harder bands still carry scratches, and the edge looks patchy under kitchen lighting. Use light pressure, keep the pad flat and moving, and check the edge under raking light after each grit. A final buff pad brings resin and stone to the same sheen.

Advanced Tips for Shops Working Figured Brazilian Stone

Seams on Typhoon Bordeaux are a design decision as much as a technical one. A seam through a busy burgundy wave hides better than one through the plain cream base, where any color difference in the adhesive or any lippage shows. When you mix seam adhesive, tint it against the actual edge of the stone where the seam will sit, not against a general color sample. Many shops mix two tints and use them on different sections of the same seam. Keep seam widths tight and flatten them carefully, because a figured pattern draws the eye to any break in the flow.

Be honest with the customer during the sale. Show them a resin-filled fissure on an actual slab and explain that it is normal for this stone, that distributors fill these during production, and that small pits may reopen during finishing and will be refilled. The same fissure discovered after install, without explanation, becomes a warranty call. A short written note on the job ticket protects both sides.

Sealing, Daily Care and Long-Term Performance

Sealing advice for Typhoon Bordeaux varies, and it is worth explaining why. The Natural Stone Institute's position is that most granite countertops do not need sealing but that sealing can further reduce absorption, and it specifically notes that sealing resin-treated slabs may add stain and moisture resistance. Arizona Tile recommends sealing its slabs with a solvent-based impregnating sealer after the stone is fully dry. Both positions point the same way for a cream-based, resin-treated stone: test it, and seal it if it absorbs.

Test on the finished, installed or ready-to-ship tops, not on a raw slab. Put a few drops of water on the light base, on a dark wave and near a filled fissure, and watch them. If the stone darkens under the drops within a short time, it is absorbing and should be sealed. Use a quality impregnating sealer that repels both water- and oil-based stains, follow the label for application and cure, and buff off all residue so no film remains. Let the stone dry fully after fabrication before you seal, because sealing over trapped moisture can leave dark patches.

Day to day, clean with warm water and a pH-neutral stone cleaner, wipe spills promptly on the light areas, and use trivets, since the resin fills are the part of the surface most sensitive to hot pans. Over the long term, the things that come back are predictable: a small pit reopening, dullness near the sink where cleaning is most aggressive, or a stain where sealer has worn. Each is fixable with the same tools used in fabrication. Refill pits with clear knife-grade epoxy, rework dull areas with fine polishing pads or a stone polishing compound, and reseal when the water test shows absorption returning. Leave the customer with a written care sheet and the name of the sealer used. That one page heads off most problems and makes any later service visit faster.

For tooling and supplies on a Typhoon Bordeaux job, start with a granite bridge saw blade such as the Alpha Silencer III Granite Bridge Saw Blade and the full range of wet core bits for cutout corners. For fissure work, a clear knife-grade epoxy such as Akemi Akepox 5010 Waterclear handles fissures, and the Akemi Coloring Paste Set tints polyester and epoxyacrylate seam adhesives to match the burgundy and cream. Edge polishing runs through our polishing pads, and for final protection see the ICR Sprint L17 solvent-based impregnator and the broader sealers and color enhancers collection.
