Exterior acrylic coating systems

100% acrylic exterior topcoat systems are the standard two-coat finish for concrete, render and masonry facades on Class 2 strata buildings. Applied over an appropriate primer, the two-coat acrylic system provides UV resistance, colour retention, and waterproofing protection. Low-sheen finishes are standard for rendered surfaces; full gloss finishes suit feature elements and trim.

What are exterior acrylic coating systems?

Exterior acrylic coatings are the most commonly specified topcoat for cement render and masonry facades in Australia. They provide UV resistance, weather protection, colour retention, and moderate flexibility at an economical cost. Applied as a two-coat system over alkali-resistant primer, they form the final weather barrier in a standard exterior painting specification.

Dulux Australia

Dulux Weathershield Exterior Acrylic

100% acrylic exterior topcoat — masonry and render facades

System Description

Dulux Weathershield is the benchmark exterior acrylic paint for masonry and render facades in Australia. The 100% acrylic binder provides excellent UV resistance, colour retention, and film flexibility, allowing the coating to move with the substrate through seasonal temperature cycling without cracking. Applied as a two-coat system over alkali-resistant primer (Dulux Weathershield Primer or equivalent), it forms a durable weather barrier on residential and commercial Class 2 strata buildings. Weathershield is available in a wide range of colours including custom Dulux tinting and is widely stocked through trade and retail channels nationally. Anti-fungal additives are included in the low-sheen formula. Confirm primer specification, DFT, and overcoat interval from the current Dulux TDS before specifying — coverage rates and DFT requirements can vary between the full range.

Technical Properties

  • Binder: 100% pure acrylic emulsion — premium UV stability and colour retention
  • DFT: approximately 35–50 µm per coat applied at recommended coverage — two-coat system = 70–100 µm
  • Coverage: approximately 12–16 m²/L — confirm from current TDS

Limitations

  • Alkali-resistant primer mandatory on new render — do not apply direct to unpainted new cement render
  • Not a crack-bridging coating — use elastomeric system where active crack movement is anticipated
  • Minimum 10°C application temperature — do not apply in wet or very humid conditions

PROCUREMENT SOURCES

Confirm suitability with the current manufacturer TDS before specifying or applying.

Wattyl Australia

Wattyl Solagard Exterior Acrylic

High-durability acrylic exterior topcoat — masonry and render

System Description

Wattyl Solagard is one of Australia's most established exterior acrylic topcoats for masonry and rendered facade applications. The product incorporates advanced UV stabilisers specifically formulated for Australian conditions — including high-UV tropical and subtropical environments — to resist chalking and colour fade. It is applied as a two-coat system over an appropriate Wattyl exterior primer or alkali-resistant primer on cement render. Solagard includes anti-fungal additives and is available in a wide range of colours through Wattyl's national tinting service. It is particularly well suited to the Queensland and northern NSW markets where UV intensity and humidity combine to accelerate coating deterioration on standard acrylic systems. Confirm primer specification, coverage rates, and DFT from the current Wattyl Solagard TDS before specifying.

Technical Properties

  • Binder: 100% acrylic with enhanced UV stabiliser package — formulated for high UV-intensity Australian environments
  • DFT: confirm from current TDS — typically 35–45 µm per coat at manufacturer's recommended spread rate
  • Coverage: confirm from current TDS — approximately 12–16 m²/L

Limitations

  • Alkali-resistant primer mandatory on new or unpainted cement render
  • Not a crack-bridging system — specify elastomeric system where substrate cracking is active or anticipated
  • Colour consistency across recoat intervals requires same batch tinting — commission new batch for touch-up areas

Haymes Paint Australia

TODO: owner confirm — Haymes Extreme Shield Exterior Acrylic (WRONG PRODUCT NAME — 'Extreme Shield' is not an active Haymes exterior acrylic product — the correct current Haymes exterior acrylic is 'Exterior Solashield®' available in Low Sheen, Matt, Satin, and Gloss finishes — confirm correct product name is 'Haymes Exterior Solashield' and update this card with current Haymes TDS data)

Do not confuse exterior acrylic coating systems with:

  • Elastomeric coating systems — thicker, high-build crack-bridging membranes formulated to bridge active hairline movement cracks — listed on the elastomeric coating systems page — different product class from standard two-coat acrylic topcoats
  • Elastomeric crack-bridging coatings — highly flexible bridge coatings applied specifically over render and masonry with active fine cracking — listed on the elastomeric crack-bridging coating page
  • Penetrating silane/siloxane water repellents — colourless, breathable water repellents that penetrate the substrate without forming a film or changing appearance — not a topcoat — listed on the penetrating silane/siloxane page
  • PVDF and fluoropolymer recoating systems — specialist two-pack fluoropolymer coatings applied to aluminium cladding panels and metal facades — not suitable for render or masonry substrates — listed under cladding metal panel recoating
  • Texture coatings — factory-blended acrylic/cement coatings containing aggregate, applied to produce a roughcast or textured finish — a different product class from smooth-finish acrylic topcoats
  • Alkali-resistant primers — the first coat applied to fresh render and masonry to seal and prepare the substrate for topcoat — not a topcoat system — listed on the alkali-resistant primer systems page

Disclaimer

General technical information only. Topcoat system must be compatible with the primer used — confirm with manufacturer TDS. Exterior acrylics require a minimum application temperature of 10°C and should not be applied in direct sun or on hot substrates. Not a substitute for professional advice.
