Selecting interior and exterior finishes for modern architectural projects requires a rigorous understanding of substrate chemistry, environmental stresses, and application efficiencies. High-exposure facades, heavy-contact public corridors, and humid wet areas each place distinct physical demands on a paint film. Since 1935, Ballarat-born Haymes Paint has focused on developing technologically advanced paint systems designed to withstand demanding Australian conditions.
Protecting Exterior Timber and Cladding in Climatic Extremes
Exterior cladding and timber facades are subjected to intense solar radiation, coastal salt air, and rapid thermal cycling. Exposure to ultraviolet (UV) radiation chemically degrades the organic binders in standard paint films, leading to chalking, colour loss, and eventual structural failure. In coastal environments, salt air exacerbates this degradation by promoting moisture retention and chemical corrosion, while alpine environments subject substrates to severe freeze-thaw cycles that force timber to expand and contract rapidly.
To withstand these extreme climatic forces, exterior specifications must prioritise paints formulated with highly flexible, UV-resistant acrylic binders. Exterior Solashield® is engineered specifically for this purpose. Utilising 100% acrylic binders and advanced Surface Lock Technology, it forms a robust barrier that repels airborne dirt, dust, and mould spores. This dirt-shedding capability prevents pollutants from embedding in the paint film, preserving the aesthetic appearance and structural integrity of the facade.
The physical specifications of this system include:
- Elasticity and Adhesion A highly flexible acrylic film that stretches and contracts alongside the natural thermal movement of timber weatherboards, masonry, and concrete substrates, preventing premature splitting.
- Salt Resistance Chemically resistant to marine salt degradation, making it highly suitable for coastal residential and commercial developments.
- Guaranteed Durability Backed by a written 20-Year Guarantee against blistering, peeling, and flaking when applied on correctly prepared substrates.
- Tinting Versatility Available in clean white and deep bases, enabling architects to implement bold, dark design palettes without compromising UV resistance or film longevity.
Resolving the Washability Dilemma in Busy Commercial Corridors
School hallways, retail spaces, and healthcare corridors represent the most demanding high-contact environments. Walls in these zones are subject to daily impacts, scuffs, and frequent cleaning cycles. Specifying traditional flat or matte paints in these corridors often leads to permanent staining and burnishing. Burnishing occurs when localised cleaning or scrubbing polishes the flat surface, creating uneven, glossy patches that ruin the visual design. Conversely, standard high-gloss paints reflect glancing light in a way that highlights plasterboard joint lines and structural imperfections.
To bridge this gap, specifiers require a paint that delivers a sophisticated, low-lustre aesthetic alongside exceptional washability. Eggshell leverages advanced polymer technology to solve this dilemma, achieving a velvet-like finish (with a gloss level of 1-5% at 60°) that absorbs and flattens acute glancing light to hide underlying wall blemishes.
The performance metrics of this polymer formulation are demonstrated through standardised testing:
- Stain Release: Laboratory testing proves that 80% of common stains, including crayon, lipstick, pen ink, tea, coffee, and food dyes, are successfully removed with a single wipe.
- Scrub Durability: The paint film is engineered to withstand up to 800 wet-abrasive scrub cycles without wearing thin or changing its gloss level.
- Sheen Stability: Displays the lowest rate of sheen change or polishing after 200 wash cycles, ensuring the velvety finish remains uniform over years of maintenance.
- Colour Integration: Fully tint-aligned to the complete colour library, allowing specifiers to implement any design scheme without sacrificing washability or durability.
Fast-Curing Trim Finishes that Resist Yellowing and Blocking
High-contact woodwork, including doors, window frames, skirtings, and architraves, requires tough, non-yellowing finishes that can withstand constant physical impacts and hand oils. Historically, these areas were coated with traditional oil-based enamels due to their surface hardness. However, solvent-based enamels release high levels of chemical fumes and undergo rapid yellowing, particularly in areas with limited natural light. Furthermore, traditional enamels suffer from slow drying and curing times, which can lead to blocking. Blocking occurs when a painted door sticks to its frame after being closed, causing the paint film to peel and ruin the finish.
Modern building specifications require a transition to water-based acrylic enamel technology. Trimplus provides a hard-wearing, non-yellowing alternative that delivers the durability of an oil-based enamel with the fast dry times of water-based systems. Touch-dry in 20 minutes with a quick 2-hour recoat window, it permits rapid project turnaround and room reoccupation. Its advanced polymer structure is non-blocking, ensuring that doors and windows can be opened and closed shortly after coating without sticking.
For heavy-duty trim projects requiring an exceptionally smooth, enamel-like appearance and the convenience of water wash-up, Trimplus provides a durable, low-odour, water-based solution.
Disguising Ceiling Flaws and Plasterboard Blemishes
Expansive interior ceiling spans represent a unique aesthetic challenge. These overhead surfaces are highly prone to flashing and visible lap lines, which occur when natural light strikes the ceiling at a flat angle, magnifying minor plasterboard joint lines and roller application defects. To mask these flaws, ceilings require ultra-flat paints that scatter light uniformly, rather than reflecting it.
Interior Ceiling Flat is chemically engineered with a specialised CWE base code to deliver an ultra-flat finish, with a 60° gloss level under 2.5. This non-reflective finish scatters light in all directions, hiding plaster patches, blemish lines, and roller lap marks.
The technical and health specifications of this ceiling paint system include:
- High Coverage: Provides a coverage rate of up to 16m2 per litre, optimising material efficiency on large commercial projects.
- Indoor Air Quality: Independent third-party certified under Global GreenTag to GreenRate Level A and Product Health Declaration PlatinumHealth, with VOC levels under 1 g/L.
- Guaranteed Integrity: Backed by a written 5-Year Guarantee against mould and biological growth in dry zones.
- High-Efficiency Hiding Power: For projects requiring total coverage over dark existing paint bases, specify Coverplus, designed to cover completely in just two coats, streamlining labour and material costs.
Combining Technical Expertise and Digital Tools
Compiling compliant, substrate-specific paint schedules for complex commercial and residential projects is a highly detailed task. Architects and specifiers must ensure that every chosen paint system complies with building codes, environmental rating systems, and regional weathering profiles. Errors in paint schedules can lead to premature film failure, costly maintenance cycles, and project delays.
To simplify this process, we provide specialised technical support and digital resources. Specifiers can access full BIM content files, allowing them to integrate precise paint systems, colour codes, and film thicknesses directly into their digital building models.
