About

This collection is the complete Berger-Seidle AquaSeal water-based finishing system - waterborne primer, topcoats and fillers for professional timber floors. AquaSeal is low-VOC and low-odour, dries fast for quicker recoats, and stays clear over pale Australian species without the ambering of solvent lacquers. Start with AquaSeal FlexPrimer for adhesion and tannin control, then match a topcoat to the traffic: CeramicStar is the ceramic-reinforced 2K workhorse for commercial floors, SmartHome suits homes, GreenStar gives isocyanate-free performance, and NordicWhite delivers a raw, limed-timber look. Pafuki mixed with fine sanding dust fills gaps to match. New to waterborne finishes? Read our water-based vs oil-based chemistry guide .

FlexPrimer improves adhesion, evens absorption and helps control tannin bleed on species such as spotted gum and blackbutt. Which topcoat suits high-traffic and commercial floors? CeramicStar is the ceramic-reinforced 2K option for the hardest wear. For a head-to-head, read AquaSeal vs Ciranova for commercial traffic . How do I fill gaps and nail holes?
