Do I need co-op or condo board approval for a microcement installation in New York?

Most New York buildings require board approval before work begins, along with a certificate of insurance and agreed work hours. Because microcement is installed over the existing surface with no demolition, approvals are often simpler than for a full renovation, but they are still required. We plan the schedule around each building's rules.

Can microcement be installed over existing tile in a New York apartment?

Yes, in most cases, and it is often the main reason the project is viable. Tiles must be clean, degreased and fully bonded; loose tiles are removed and voids filled. Deep grout joints usually require a leveling layer first. This avoids demolition, dumpsters and freight elevator logistics.

Does microcement add much height or weight to a floor?

No. The system is installed in roughly 7 to 9 thin layers totaling about 1/8 inch, so it adds minimal load and almost no floor height. This matters in New York where door clearances, thresholds and building weight limits are fixed.

Will microcement crack in a New York building?

Microcement follows the substrate underneath it. Cracks appear when the substrate moves or was not properly prepared, not because of the finish itself. Existing cracks are treated at the source and reinforcement is specified where movement is expected.

Can microcement be used on a New York terrace or roof deck?

Yes, with the correct specification. Exterior terraces face freeze-thaw cycles and standing water, so drainage slopes must be functional and approved waterproofing membranes are mandatory beneath the system.

Why Topcret

Not another installer — the source of the system.

New York has no shortage of microcement installers. What sets Topcret USA apart is simple: we don't buy someone else's product to apply it — we're the U.S. distributor of the Topcret system itself.

That means EcoCemento®, Baxab®Eco, Real Metals®, Clay® and T/Grip, installed by specialists who know these systems better than anyone. Microcement — sometimes called microtopping or micro cement — is only as good as the system behind it, the substrate underneath it, and the hands that install it.

In New York that matters more than elsewhere. Building rules, access windows and neighbors above and below leave no room for a job that has to be redone. We specify before we price: substrate, moisture, exposure, traffic and finish.

Buildings & conditions

Specified for New York buildings.

New York is less about weather than about buildings — and the two together create conditions most installers underestimate.

Pre-war apartments have uneven slabs and layers of previous finishes. New high-rises have movement and deflection that a rigid surface has to accommodate. Terraces face freeze-thaw cycles that will find any weakness in a sealer. Interior heating strips humidity out of the air in winter, then summer brings it back.

Each of these changes the specification: the primer, the number of layers, the reinforcement mesh where movement is expected, and the protective sealer selected for the exposure that surface will actually face.

New York considerations

What New York projects require.

Microcement is installed in thin layers — roughly 1/8 inch total — over an existing, properly prepared substrate. In New York, that thinness is often the reason the project is possible at all.

Co-op & condo boardsMost buildings require board approval, insurance certificates and defined work hours. We plan the schedule around building rules rather than assuming access.

No demolitionInstalling over existing tile avoids demolition, dumpsters, freight elevator bookings and weeks of noise — usually the deciding factor in an occupied building.

Weight and buildupAt roughly 1/8 inch, microcement adds minimal load and almost no floor height, which matters where door clearances and thresholds are fixed.

Compact bathroomsSeamless wet areas with no grout lines make small New York bathrooms read larger and are far easier to keep clean.

Terraces & setbacksExterior terraces face freeze-thaw and standing water. Drainage must work and waterproofing membranes are mandatory before any microcement goes down.

Pre-war floorsUneven or previously patched slabs are leveled first. Microcement follows the geometry underneath it — it does not hide it.

Where we work

Across New York.

Residential and commercial projects across Manhattan, Brooklyn, Queens, the Bronx and Staten Island, plus Westchester County, Nassau County and Long Island's North Shore including Sands Point, and the Hamptons — apartments, townhouses, restaurants, hotels, retail and office spaces.

We work directly with interior designers, architects, general contractors and private clients — on homes, restaurants, hotels, retail spaces and hospitality projects where the surface is part of the design, not an afterthought.

Cost

What drives the price of a microcement project.

There is no honest single price per square foot for microcement — and anyone quoting one before seeing the space is guessing.

Substrate condition. The single biggest variable, and in New York the least predictable. Pre-war slabs, previous patch repairs, uneven planes and layers of old adhesive all add preparation before a single layer goes down. Substrate preparation is where most projects are won or lost.

Area and layout. Square footage matters, but so does shape. One open 2,000 sq ft floor costs less per foot than five small bathrooms totaling the same area — edges, corners and transitions are where the labor goes.

System and finish. Baxab®Eco for heavy traffic, EcoCemento® for a more textured look, Real Metals® or Clay® for specific effects — each has a different material and labor profile.

Exposure and waterproofing. Wet areas and exteriors require membranes and specific sealers that interior dry areas do not.

Access and schedule. High-rise access, freight elevator scheduling, restricted work hours, occupied apartments and building insurance requirements all affect cost in New York more than in most markets.

We quote after reviewing the actual conditions — square footage, substrate, exposure and finish. That is the only way to give a number that will still be true when the job is done.

Does it add height or weight?No. Roughly 1/8 inch total, so minimal load and almost no floor height — important where thresholds and clearances are fixed.

Will it crack?Microcement follows the substrate. Cracks come from substrate movement or poor preparation, not from the finish. Existing cracks are treated at the source.

Can it be used on a terrace?Yes, with correct specification. Freeze-thaw and standing water mean drainage must work and waterproofing membranes are mandatory.
