Liquid Glass Coating AQ SHIELD

Stop buildings from deteriorating.Apply it, and it becomes glass.

AQ SHIELD is a liquid glass coating: apply it at room temperature, and as it dries it turns into glass. Its inorganic film — made without petroleum-based raw materials — protects materials from ultraviolet rays, water, and salt, extending the service life of buildings and structures while keeping them beautiful.

CONCEPT

From "repair after it deteriorates" to "prevent deterioration in the first place"

Building deterioration has long been considered unavoidable. But its causes — ultraviolet rays, water, carbon dioxide, and salt — enter from outside. Stop them at the surface of the material, and a building stays beautiful for far longer. AQ SHIELD is the coating made for exactly that.

01

Glass barely degrades

Glass is an inorganic material, like stone and sand, and resists physical change. That is fundamentally different from petroleum-based resin coatings, whose molecules are broken down by ultraviolet rays.

02

Far longer intervals between repainting

When the film lasts, the number of major scaffolded renovations itself goes down. Lowering a building's life-cycle cost is the single biggest benefit of extending its service life.

03

No harmful substances released

With silica as its main component, nothing harmful leaches into water and no toxic gases are produced if it burns. A coating designed with people and the environment in mind.

TECHNOLOGY

At the core of the technology: the composite glass binder

Conventional coatings build performance by mixing additives such as urethane or silicone into a resin binder (the component that acts as the adhesive). AQ SHIELD reverses the idea: silica-based materials are encapsulated inside a glass binder. Because no additives are exposed at the surface, performance lasts far longer.

Turns to glass with no heat treatment. Glass is normally made by melting at high temperatures, but AQ SHIELD forms a glass film simply by being applied at room temperature and drying — and it is a glass that flexes with the substrate instead of cracking.

One coat is all it takes. No primer is needed, and it can be applied to a wide range of materials — metal, stone, wood, concrete, tile, and more (a dedicated primer may be used depending on the application and material).

Think of it this way: a glass cup vs. a plastic cup

A glass cup is still clear after ten years of use; a plastic cup turns cloudy and worn. The difference between a resin coating and a glass film starts at the material itself.

  • A film dirt cannot penetrate

    The glass binder film is so dense that dirt cannot work its way inside. Dirt that lands on the surface washes off easily, so good looks last.

  • Blocks the causes of deterioration at the surface

    It suppresses the ingress of ultraviolet rays, water, carbon dioxide, and salt, preventing concrete carbonation and the progression of rust on metal.

  • A thin yet strong film

    The thin film preserves the texture of the material — and for tile color changes, it can change only the color while keeping the joints and texture intact.

How it differs from conventional resin coatings

AQ SHIELDConventional resin coatings
Film materialInorganic glass (silica-based)Petroleum-based organic resins (urethane, silicone, fluoropolymer, etc.)
How it degradesResists material change, so performance lastsUV degrades the resin and performance gradually declines
Weather resistance25 years of weather resistance (manufacturer's published guideline)Typically around 10–15 years before repainting, depending on type
PrimerIn principle no primer; one coat (a dedicated primer may be used for some applications)Primer + intermediate coat + topcoat is the norm
SafetyThe cured film complies with Food Sanitation Act standards; no harmful substances leach outVaries by product

Tile Exterior Walls & Large-Scale Renovation

Renovation proposals specialized in the tile exterior walls of office buildings and condominiums. A clear coat can bring back color and gloss; a color coat can change only the color while preserving texture and joints. AQ Co., Ltd. is your single point of contact, and direct construction keeps intermediary margins down.

CASE STUDIES

Case Studies — In Actual Photographs

Real results, not advertising copy. Here are two representative large-scale tile exterior renovations by AQ Co., Ltd. — every photograph is an actual construction photo, not a stock image.

A tile-clad building in Funabashi, Chiba, during renovation with scaffolding in place (actual construction photo)
Before / during
The building after its tile color change — a fresh, contemporary gray exterior (actual construction photo)
After
Funabashi, ChibaTile-clad buildingApprox. 35 years oldColor change

A 35-year-old tile building, renewed with a color change"It was only repainted — but it looks re-tiled."

After scaffolding, high-pressure washing, tile repair, and sealant replacement, the tiles were recolored with AQ SHIELD Color. The beige tile exterior with its green band was reborn as a clean, contemporary gray facade.

Ordinary paint forms a thick film that buries the texture of the tile and fills the joints. AQ SHIELD's film is thin and its inorganic pigments bond directly to the tile, so only the color changes — texture and joints stay exactly as they were, as the close-up below shows.

Close-up of the tile wall after the color change — joint lines and tile texture fully preserved
Close-up after color change — joints and texture intact
Occupancy 75% → 100%Vacancies were conspicuous before the renovation; once work was complete, the building filled up completely.

Ichikawa, Chiba8-story condominiumApprox. 15 years oldClear coating

Clear coating that protects color and texture as they are"No color was applied — yet the color came back."

After tile repair, high-pressure washing, and sealant replacement, the work was finished with an AQ SHIELD clear coat — no color change, just a glass film protecting the tile's original color and texture.

After about 15 years, UV and rain had faded and dulled the tile. The rooftop penthouse, exposed to strong sunlight and — being near the sea — salt-laden winds, had deteriorated considerably. Yet once the clear coat was applied, the faded tile regained its color and gloss without any color being added, coming back to life with a like-new look.

Won against two competing quotesCompetitors quoted about ¥26 million; AQ Co., Ltd. quoted about ¥23 million (a difference of roughly ¥3 million) — and was chosen on the scope of work, not price alone.

* Figures are from the competitive quotes for this property (an 8-story condominium). Costs vary with the condition of the building and the work specifications.

The official site also shows examples such as tile (left: untreated / right: coated), granite exterior walls, and concrete fences. See the case studies PDF above for details.

The MARINE / MARINEα hull coatings are patented as an "antifouling coating that suppresses marine organism attachment" (patent holder: Fect Co., Ltd.).

Adopted for 250,000 wooden plates

AQ SHIELD coats 250,000 wooden plates for a major restaurant chain — a case where another company's product had not worked, and switching to AQ SHIELD succeeded.

Published case studies

Actual construction photos — the Funabashi color change, the Ichikawa clear coating, and more — are published in the Case Studies section of this page. Tile, granite, and concrete fence examples are also in the case studies PDF.

FAQ

Frequently Asked Questions

What materials can it be applied to?

A wide range: metal, stone, wood, concrete, tile, plastic, leather goods, and more. There are products for everything from bridges, dams, and tunnels to exterior walls, roofs, floors, boats, and tableware. Depending on the condition of the material, substrate preparation or a dedicated primer may be required.

Is a primer really unnecessary?

For most applications, no primer is needed and a single coat adheres strongly. For some applications and materials, however, a dedicated primer is used (for example, boat propellers). Please contact us for details.

How long does it last?

The manufacturer's published guideline is 25 years of weather resistance. This is not a guaranteed value — actual durability depends on the condition of the material, the sea area, and the environment of use. For hull coatings, a service life of over 10 years is the guideline.

Can I request an estimate or a site survey?

Yes. Building renovation, waterproofing, and AQ SHIELD coating work in the Tokyo metropolitan area is handled by direct construction. Feel free to ask about site surveys and estimates — and about purchasing coating only.
