Why TERRAZZO GraniTech
The Cement-Free Alternative to Microcement
TERRAZZO GraniTech is a patented, cement-free seamless surface system made from natural granite and acrylic resin. Applied in thin layers, it creates continuous architectural surfaces with quiet movement and depth — across interiors, exteriors and wet areas.
The strength is in the system. Primer, finish and sealer are formulated and tested to work together, so what goes on the wall is specified rather than assembled on site.
Why Specifiers Choose
TERRAZZO GraniTech
Crack Resistance,
Built Into the Resin
Memory resin technology gives the cured finish a flexibility that rigid, cement-based systems do not have. The result is a continuous surface engineered to accommodate normal substrate movement — the most common source of hairline cracking in cement-based plasters and microcements.
Installs Over Existing Surfaces, Often Without Demolition and Permits
With proper preparation, TERRAZZO GraniTech installs over tile, drywall, cement board and concrete. Leaving the substrate in place shortens the schedule, reduces disruption on site, and keeps demolition debris out of the project.
One System,
Interior to Exterior
The same system specifies across walls, floors, ceilings, wet areas, countertops, cabinetry, pool decks and pool interiors. One material, one detail language, fewer transitions to resolve.

How It Performs
Full-Body Performance, Not a Surface Coating
TERRAZZO GraniTech cures into a dense composite, with mineral aggregate locked into a resin matrix. Performance comes from the full thickness of the material rather than from a film on top — closer to engineered stone than to a coating. It wears evenly and it ages evenly.
Built for Bathrooms, Showers and Wet Areas
TERRAZZO GraniTech resists water before sealing. The sealer is then selected for sheen and for the cleanability, stain and traffic protection each space requires. In showers, install over a waterproofing membrane meeting ANSI A118.10.

The Next Generation of Plaster Solutions
Nine Years Applying Microcement. Then We Built the Alternative.
TERRAZZO GraniTech USA started in 2009 as microcement applicators. Nine years on job sites taught us where cement-based systems fail: hairline cracking, lap lines, and trouble in wet areas.
In 2018 we introduced TERRAZZO GraniTech — a cement-free seamless surface system built to solve the problems we had spent nine years working around.

Frequently Asked Questions
Is TERRAZZO GraniTech a microcement alternative?
Is it waterproof even before sealers?
Yes — TERRAZZO GraniTech is inherently waterproof prior to sealing. Sealers are typically applied to tune the finish and add stain, chemical, and traffic protection for the specific use case.
Is TERRAZZO GraniTech a “waterproofing membrane”?
Do I need waterproofing under it in showers / wet rooms?
Yes — in showers, wet rooms, continuously wet areas, exterior areas, and slabs on grade, waterproofing (and/or vapor management) should be addressed at the substrate level per code and exposure. Terrazzo GraniTech then becomes the finished seamless surface.
Can TERRAZZO GraniTech be used in showers and wet areas?
Can it go over existing tile without demolition?
In many cases, yes. It can be installed over existing tile (and other stable substrates) with the correct prep, adhesion system, and detailing — reducing demolition and speeding remodel timelines.
What surfaces can it be applied to?
Can TERRAZZO GraniTech be applied directly to metal?
Is TERRAZZO GraniTech suitable for exterior surfaces, pool decks, patios, walkways etc?
How thick is the system?
What environmental conditions should we avoid during installation?
Is this product low-VOC / low odor?
Yes — TERRAZZO GraniTech is low-VOC and low odor when used per spec. For compliance language, reference the current SDS/TDS for the exact values and statements.
Do you install, or do you have certified installers?
Does TERRAZZO GraniTech change color as it dries (like microcement can)?
TERRAZZO GraniTech is designed to be more color-stable and predictable than many cement-based microcement systems, which can shift as moisture evaporates and hydration occurs. Final appearance can still be influenced by substrate uniformity, mixing consistency, application technique, drying conditions, and sealer selection. For critical color matching, we recommend a small test panel using the full system build and the intended sealer sheen.
Is TERRAZZO GraniTech difficult to mix (like bag + resin systems)?
No. TERRAZZO GraniTech is supplied as a premixed, ready-to-use paste in a bucket (untinted) — not separate bags and resins requiring complex batching. To prepare it, you add pigment and a measured amount of water (typically about 6.8 oz, per your system spec), then mix thoroughly according to the latest instructions.
Is TERRAZZO GraniTech a self-leveling or floor-leveling system?
No. TERRAZZO GraniTech is a trowel-applied decorative plaster / continuous surface finish, not a self-leveling underlayment. It will follow the substrate, so the surface must be properly flattened/leveled and prepped first (as needed) using appropriate patch/leveling materials for the substrate and application. TERRAZZO GraniTech is used to create the final seamless architectural finish, not to correct waves, dips, or out-of-level floors. Do not apply thicker than the recommended system build — overbuilding can interfere with proper curing and performance.
Is TERRAZZO GraniTech just one product?
Will TERRAZZO GraniTech crack?
How long does TERRAZZO GraniTech last?
With correct substrate preparation, proper installation, and appropriate maintenance with resealing as required, TERRAZZO GraniTech is designed for long-term durability. Lifespan depends heavily on traffic level, exposure (wet areas/exteriors), cleaning chemistry, and the sealer system used. In many residential and light-commercial environments, the finish can perform for many years, with periodic resealing as part of normal lifecycle maintenance — similar to other premium continuous surface and architectural finish systems.
Do you offer a warranty?
How do you clean TERRAZZO GraniTech surfaces (PU-sealed), and can I use a steam mop?
For routine cleaning, use a pH-neutral cleaner and a microfiber mop. Always dry dust first (microfiber dust mop/vacuum with soft head) to remove grit — grit is the main cause of dulling and micro-scratches. Avoid abrasive pads/powders and absolutely avoid “no-rinse” cleaners, which leave residue that gradually degrades PU sealers. If a stronger chemical is ever used (e.g., heavy degreaser, bleach etc), it must be immediately thoroughly rinsed off with clean water afterward and not left to dwell on the surface.
We generally do not recommend steam mops on PU-sealed continuous surfaces. Heat and moisture can accelerate sealer wear and may cause hazing/whitening in micro-scratches over time. If a steam mop is used, wait until the system is fully cured, use the lowest setting, keep it moving (no dwell), and avoid frequent steam cleaning as routine maintenance.
Pro tips: use entry mats in sandy areas, add felt pads under furniture, and wipe spills promptly for best long-term appearance.
What sealer system is recommended for microtopping and microcement-style floors and walls?
Do I need to put pads on my furniture?
Why could dark spots, bubbles, or blistering potentially appear on microcement and microtopping floors?
Does the timing of a problem indicate the cause?
Often, yes. Issues appearing within hours to days generally relate to application and site conditions during installation. Factors such as temperature during application, cure times between coats and other factors are important. However, issues appearing months later more commonly relate to substrate conditions — batch, ratio, and cure defects declare themselves early rather than after a period of normal service. Seasonal timing can also be informative, as slabs frequently transmit more vapor in humid months than in dry or heating season. Sudden, localized damage may indicate a discrete water source such as a plumbing leak or failed sealant. Determining the actual cause on any given project is a matter for the installing contractor or a qualified professional with access to the site.
Does TERRAZZO GraniTech stop moisture rising through a concrete slab?
No. TERRAZZO GraniTech is an inherently waterproof decorative surface prior to sealing, meaning it resists water from the surface — which is why it performs in showers, wet rooms, pool surrounds, and exterior exposure. It is a decorative surface, NOT a vapor barrier and does not resist hydrostatic pressure or vapor drive from beneath the substrate. No topical decorative finish does, including microcement, epoxy, polished concrete, and tile. Vapor drive is a substrate condition and the remedy is installed below the finish, never within it. Decorative finishes rely on the preparation being performed properly and any decorative finish is only as good as the substrate beneath it.
Is substrate moisture testing required before installation?
Yes. Substrate moisture and vapor conditions must be evaluated before any primer or finish is applied, and results must fall within the limits published in the current spec sheet.
Selecting appropriate test methods, interpreting results, and determining whether vapor mitigation is required are professional judgments that depend on the specific slab, building, climate, and application. Recognized industry standards exist for this purpose. These evaluations should be performed by the installing contractor or another qualified professional with direct access to the site and knowledge of the conditions. We do not specify testing procedures and do not evaluate substrates remotely, any advice we may provide should be confirmed by the installing professional or other contractor.
Who is responsible for substrate preparation and moisture verification?
TERRAZZO GraniTech is a material supplier, not an installation company. Substrate assessment, moisture and vapor evaluation, mitigation, and preparation are the responsibility of the installing contractor, as stated in our published application instructions and spec sheet. We supply the system and provide product-related technical support; we are not on site and do not control preparation, installation, or site conditions. Workmanship warranties are provided by the installer – installers are responsible of approving existing substrate conditions and installation conditions, curing times and any other installation related factor that is important for a successful outcome.
Can TERRAZZO GraniTech be repaired?
