Bona Traffic HD
Bona Traffic HD is the most specified commercial water-based floor finish in Australia. It carries a published Taber abrasion rating of 1.5 mg per 100 revolutions under SIS 923509 -- a standardised, independently verifiable test. That published number is why architects and specifiers put it on drawings.
Traffic HD ships in three sheens: Extra Matt (10%), Matt (20%), and Satin (45%). The extra matt option is particularly useful for the natural-look residential trend without sacrificing the commercial-grade wear layer. VOC is 50 g/L -- compliant with Green Star and NCC indoor air quality thresholds.
The system advantage is significant. Traffic HD is formulated to work with Bona Prime Intense (for high-tannin species like blackbutt and spotted gum), Bona Classic UX (general-purpose primer), and the full Bona stain range. Every product in the chain is tested against the next, eliminating adhesion and compatibility risk.
Loba 2K Duo
Loba 2K Duo is a two-component water-based finish from Loba, a German manufacturer now part of the ARDEX/WAKOL group. It is positioned as their premium commercial topcoat and competes directly with Traffic HD in the 2K space.
Coverage is rated at 8--10 m²/L, matching Traffic HD. VOC is stated as less than 50 g/L. Loba does not publish a Taber abrasion wear rating for 2K Duo on their Australian-facing documentation, which makes direct hardness comparison difficult to verify independently.
Loba 2K Duo is available in Matt and Satin sheens -- no extra matt option. The pack format is 5L plus a separate hardener component. Contractors who have used both products note that Loba 2K Duo builds a hard film, but the lack of published test data means the comparison relies on anecdotal experience rather than standardised numbers.
Where to buy each in NSW
- Bona Traffic HD: Sand-Aid, Toronto NSW -- NSW's only Bona Premier Dealer. Full Bona system in stock: primers, topcoats, stains, adhesives, maintenance. Delivery across Newcastle, Hunter Valley, Central Coast, and Sydney.
- Loba 2K Duo: Alex Lind Flooring Supplies, Padstow, Sydney. Alex Lind stocks both Bona and Loba product lines, plus Hermes and Norton abrasives.
When to pick Bona Traffic HD
- Published wear data matters. Traffic HD has a tested, published Taber abrasion number. For jobs where the specifier or client needs documented performance, Traffic HD provides that in writing.
- Three sheens needed. The Extra Matt 10% sheen gives a near-invisible finish that Loba 2K Duo does not offer. Useful for the natural-timber aesthetic on residential and boutique hospitality projects.
- System compatibility is non-negotiable. Traffic HD is tested with every Bona primer and stain. No guesswork on inter-coat adhesion when the entire stack is Bona.
- High-tannin Australian hardwoods. Bona Prime Intense is purpose-built for blackbutt, spotted gum, tallowwood, and ironbark. Loba's primer range does not have a direct equivalent for high-tannin Australian species.
- Regional NSW supply. Sand-Aid keeps Traffic HD and the full Bona range in stock in Toronto NSW. No waiting for Sydney freight on a Wednesday afternoon.
When to pick Loba 2K Duo
- Already running Loba. If the existing floor is finished with Loba, recoat with Loba. Cross-system recoats carry adhesion risk that is not worth taking.
- ARDEX/WAKOL ecosystem. Loba is now part of the ARDEX/WAKOL group. Contractors already buying ARDEX adhesives and WAKOL products may prefer consolidating with one distributor relationship.
- Preference for the Loba cure profile. Some contractors prefer the working characteristics of Loba 2K Duo. That is a valid reason to stick with it -- the product builds a hard film and has a following among experienced operators.
A note on published specs
Bona publishes a Taber abrasion wear rating, VOC figure, recoat time, walk-on time, and full cure time for Traffic HD. Loba publishes coverage and VOC for 2K Duo but does not publish a wear rating or cure timeline on their Australian-facing documentation. This does not mean Loba 2K Duo is a lesser product -- it means the comparison on hardness and durability cannot be made using standardised numbers. Contractors making a choice should weigh published data alongside their own on-site experience with each product.
