Acrylic
A type of synthetic paint that uses acrylic polymer resins as the binder. It creates a plastic-like film over the substrate rather than penetrating it.
- Why it matters: While common, acrylics can trap moisture in walls and contribute heavily to microplastic pollution.
Adhesion
The physical or chemical ability of a paint to stick to the underlying surface. Poor adhesion leads to peeling and flaking over time.
- Why it matters: Strong adhesion ensures the long-term integrity and durability of the protective coating.
Alkalinity
A measure of how basic (non-acidic) a substance is, typically represented by a high pH level. True mineral paints are naturally highly alkaline.
- Why it matters: High alkalinity naturally inhibits the growth of mould and mildew without relying on toxic chemicals.
Biocide
A chemical additive used in conventional paints to kill or prevent the growth of biological organisms like mould, algae, and bacteria. These chemicals often leach out of the paint over time.
- Why it matters: Avoiding biocides protects local ecosystems and prevents harmful chemical off-gassing into indoor air.
Binder
The core ingredient in paint that holds the pigment particles together and secures them to the surface. It determines the paint’s primary characteristics, such as durability and breathability.
- Why it matters: Mineral paints use silicate binders that permanently fuse with walls, unlike plastic binders that merely sit on top.
Blistering
The formation of bubbles on the surface of a paint film, usually caused by trapped moisture or heat attempting to escape from the substrate. It is a common failure mechanism in conventional film-forming paints.
- Why it matters: Preventing blistering requires a highly breathable paint system that allows water vapour to pass through freely.
Breathability
The ability of a material to allow water vapour to pass through its structure. In architectural coatings, this prevents moisture from becoming trapped inside masonry walls.
- Why it matters: Highly breathable coatings protect buildings from structural dampness, interior rot, and widespread paint failure.
Carbon Sequestration
The process of capturing and storing atmospheric carbon dioxide. Some advanced building materials naturally absorb CO2 from the air during their chemical curing process.
- Why it matters: Paints that actively sequester carbon help directly reduce the overall carbon footprint of a building project.
Chalking
The formation of a fine powder on the surface of a paint film caused by the degradation of the binder, typically due to prolonged UV exposure. While a little chalking is normal over decades, excessive amounts indicate poor binder quality.
- Why it matters: UV-stable mineral paints resist severe chalking, keeping facade colours vibrant for significantly longer.
Coverage
The surface area a specific volume of paint can coat effectively, usually measured in square feet per litre (sq.ft/L). It varies based on the paint’s formulation and the porosity of the substrate being painted.
- Why it matters: Accurate coverage rates are essential for calculating project costs and minimizing material waste during application.
Cradle-to-Gate
A partial life cycle assessment measuring a product’s environmental impact from resource extraction (the cradle) to the factory gate, just before it is transported to the consumer. It accounts for all raw material and manufacturing emissions.
- Why it matters: It provides a transparent, verifiable baseline for architects to compare the true upfront environmental cost of building materials.
Cure Time
The total duration required for a coating to fully harden and reach its maximum structural properties. This is chemically different from “dry time,” which simply means the surface is no longer wet to the touch.
- Why it matters: Respecting precise cure times ensures the coating performs exactly as specified and achieves maximum durability.
Distemper
An early type of inexpensive, traditional paint made from chalk, water, and an animal glue or natural resin binder. It is highly breathable but lacks durability and weather resistance.
- Why it matters: While historically significant for breathability, modern mineral silicate paints offer the same vapour permeability with vastly superior longevity.
Dry Film Thickness (DFT)
The exact thickness of a coating after it has fully dried and cured, usually measured in microns. It dictates the protective power and visual opacity of the final architectural finish.
- Why it matters: Achieving the correct DFT is critical for upholding manufacturer warranties and ensuring long-term facade protection.
Efflorescence
A crystalline, salty deposit that appears on masonry surfaces when water evaporates, leaving behind dissolved building salts. The pressure from these salts can easily push topical paints off the wall, causing widespread peeling.
- Why it matters: Breathable mineral paints allow moisture to escape without trapping salts beneath the surface, greatly reducing efflorescence damage.
Embodied Carbon
The total greenhouse gas emissions generated throughout a building material’s entire lifecycle, including extraction, manufacturing, and transport. It represents the “upfront” carbon cost of a building before it is even occupied.
- Why it matters: Lowering embodied carbon by choosing sustainable, recycled materials is crucial for combating climate change in the construction sector.
Emulsion
A water-based paint where polymer particles (like acrylic or vinyl) are suspended in water. As the water evaporates, the particles fuse to form a continuous, impermeable plastic film.
- Why it matters: Standard emulsions are highly prone to trapping moisture inside walls, making breathable mineral alternatives structurally superior.
Enamel
A broad term for paints that dry to a hard, usually glossy, and opaque finish. They are typically solvent-based and used for high-wear surfaces like doors and trims.
- Why it matters: Traditional solvent-based enamels contain high levels of VOCs, posing significant risks to indoor air quality and occupant health.
Exterior Paint
Coatings specifically formulated to withstand harsh outdoor environmental conditions, including UV radiation, rain, and temperature fluctuations. They require exceptionally high durability and weather resistance.
- Why it matters: Using specialized exterior mineral paints ensures long-term facade protection without fading or peeling in extreme climates.
Film Formation
The physical process by which liquid paint transitions into a solid, continuous layer on the surface of a substrate. In synthetic paints, this creates a sealed, often impermeable barrier.
- Why it matters: Unlike film-forming paints, silicate paints penetrate the wall, completely avoiding the common issues of trapped moisture and surface peeling.
Fire Class A1
The highest European fire safety classification, indicating that a material is completely non-combustible. It does not contribute to a fire at any stage or release dangerous toxic gases.
- Why it matters: Specifying A1-rated paints guarantees maximum fire safety for building occupants and complies with strict commercial building codes.
Fly Ash

A standardized, scientific method for evaluating the environmental impacts associated with all the stages of a product’s life. It measures everything from initial energy use to end-of-life emissions.
- Why it matters: An LCA provides quantifiable, third-party proof of a product’s sustainability claims, preventing corporate greenwashing.
LEED
Leadership in Energy and Environmental Design, a globally recognized green building certification program. It awards points based on sustainable building strategies, including indoor environmental quality and material sourcing.
- Why it matters: Specifying zero-VOC, sustainable paints helps secure crucial LEED points for ambitious green architectural projects.
Lime Wash
A traditional, highly breathable coating made from slaked lime and water that penetrates porous masonry. It creates a beautiful mottled finish but requires frequent reapplication and tends to chalk heavily.
- Why it matters: Mineral silicate paints offer the aesthetic charm and breathable benefits of lime wash, but with permanent, weather-resistant durability.
Masonry
Construction made from individual units laid in and bound together by mortar, such as brick, stone, or concrete blocks. These materials are highly porous and naturally alkaline in their chemistry.
- Why it matters: Masonry requires highly breathable, alkaline-compatible coatings to remain structurally sound over decades.
Microplastics
Extremely small pieces of plastic debris resulting from the disposal and breakdown of consumer products and industrial waste. Standard acrylic and emulsion paints are a massive, often overlooked source of microplastic shedding into the environment.
- Why it matters: Choosing eco-mineral paints completely eliminates paint-derived microplastics, actively protecting surrounding soil and waterways.
Mineral Silicate Paint
An advanced, eco-friendly coating that uses liquid glass (potassium silicate) as its primary binder. It chemically bonds with masonry substrates rather than forming a topical plastic film.
- Why it matters: It represents the ultimate architectural standard in durability, breathability, and non-toxic surface protection.
pH
A scale used to specify the acidity or basicity of an aqueous solution. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic (alkaline).
- Why it matters: Paints with naturally high pH levels (11-12) create harsh alkaline environments where mould and bacteria simply cannot survive.
Pigment
Finely ground powders that give paint its distinct colour and visual opacity. They can be synthetic organics or derived from natural inorganic earth minerals.
- Why it matters: Inorganic mineral pigments provide unmatched UV stability, ensuring exterior building colours never fade over time.
Plaster
A building material used for the protective or decorative coating of interior walls and ceilings. Common types include cement, gypsum, and lime plaster, all of which are highly porous substrates.
- Why it matters: Applying mineral paint to fresh plaster allows the wall to continue curing and breathing naturally without trapping moisture.
Potassium Silicate
Also known as liquid waterglass, it is the fundamental inorganic binder used in true mineral paints. It reacts chemically with the calcium present in masonry to form an inseparable bond.
- Why it matters: This specific compound is the scientific secret behind the extreme 20+ year functional lifespan of silicate paints.
Pozzolanic Reaction
A chemical reaction that occurs when a siliceous material reacts with calcium hydroxide in the presence of water to form strong cementitious compounds. This process hardens and strengthens the material over time.
- Why it matters: Leveraging this natural reaction allows upcycled industrial ashes to create incredibly strong, durable paint binders.
Primer
A preparatory coating put on materials before the main paint system is applied. It ensures better adhesion of the topcoat, seals porous surfaces, and provides additional chemical protection for the substrate.
- Why it matters: The right primer ensures the chemical bonding process of mineral paints functions flawlessly across varying and uneven substrates.
RHA (Rice Husk Ash)
An agricultural byproduct generated by burning rice husks for biomass energy. It is exceptionally rich in amorphous silica, making it a highly reactive and valuable pozzolan.
- Why it matters: Upcycling RHA into paint binders turns agricultural waste into high-performance, carbon-reducing building materials.
SCAQMD
The South Coast Air Quality Management District, a regulatory agency in California known for having the strictest air quality and VOC emission standards in the world. Rule 1113 specifically regulates architectural coatings to protect public health.
- Why it matters: Compliance with SCAQMD ensures a paint is globally recognized as inherently safe and ultra-low in toxic emissions.
sd Value
A measurement of a material’s equivalent air layer thickness, indicating how resistant it is to water vapour diffusion. A lower sd value means the material is highly breathable.
- Why it matters: Paints with an sd value of < 0.01 m guarantee maximum breathability, keeping building envelopes consistently dry and healthy.
Silicification
The chemical process where a silicate binder reacts with the minerals in a masonry substrate to form a permanent microcrystalline bond. The paint effectively becomes petrified into the wall itself rather than sitting on top.
- Why it matters: This permanent fusion makes peeling and flaking physically impossible, drastically extending architectural maintenance cycles.
Silification
An alternate spelling and synonymous term for silicification. It describes the exact same chemical fusion process between liquid silicates and mineral building substrates.
- Why it matters: Recognizing this term is essential for understanding the unique, non-film-forming nature of advanced mineral coatings in industry literature.
SRI (Solar Reflectance Index)
A measure of a surface’s ability to reflect solar heat, combining both thermal reflectance and thermal emittance. Materials with higher SRI values remain significantly cooler in direct sunlight.
- Why it matters: High-SRI exterior coatings actively reduce the urban heat island effect and lower building cooling costs.
Substrate
The underlying surface or material that is being painted or coated, such as concrete, brick, wood, or plaster. The chemical and physical characteristics of the substrate dictate the type of paint required.
- Why it matters: Matching a true mineral paint to a porous mineral substrate ensures proper silicification and maximum coating longevity.
Topcoat
The final, outermost layer of a multi-layer coating system. It provides the required aesthetic finish (colour and sheen) and serves as the primary barrier against environmental elements.
- Why it matters: A high-quality mineral topcoat delivers permanent UV resistance, weatherproofing, and structural colour stability.
Undercoat
An intermediate layer of paint applied after the primer but before the final topcoat. It builds film thickness, covers minor surface imperfections, and provides a uniform base colour.
- Why it matters: While sometimes skipped, a proper undercoat ensures the final aesthetic finish is rich, even, and long-lasting.
Upcycling
The process of transforming industrial byproducts, waste materials, or unwanted products into new materials of higher quality and greater environmental value. It is a core principle of the modern circular economy.
- Why it matters: Utilizing upcycled feedstocks drastically lowers the embodied energy and overall carbon footprint of new architectural coatings.
Vapour Permeability
The specific rate at which moisture vapour can pass freely through a solid material. It is a critical performance metric for architectural coatings applied to porous building envelopes.
- Why it matters: High vapour permeability prevents the dangerous accumulation of interior moisture, safeguarding against structural rot and indoor mould.
VOC (Volatile Organic Compounds)
Harmful carbon-based chemicals that easily evaporate into the air at room temperature. They are commonly found in traditional solvent-based paints, modern plastics, and conventional building materials.
- Why it matters: Zero-VOC paints completely eliminate toxic off-gassing, preventing “sick building syndrome” and ensuring safe indoor air quality from day one.
Waterglass
The traditional common name for liquid sodium or potassium silicate solutions. In the premium paint industry, potassium waterglass is exclusively used due to its superior weather resistance and lack of salt efflorescence.
- Why it matters: It acts as the sustainable, completely inorganic glue that permanently bonds true mineral paints to masonry structures.
Wet Film Thickness (WFT)
The exact thickness of a freshly applied, wet coating before any solvent or water has evaporated. It is measured during the application process to ensure the correct volume of paint is being used.
- Why it matters: Monitoring WFT closely allows applicators to guarantee the paint will dry to the manufacturer’s specified protective thickness.
