Polysulphide Expansion Joint Sealant Is Incompatible With Epoxy — Check the Joint Filler Before Marking Over It
A Brendale manufacturing facility had recently had expansion joints refilled as part of a concrete slab maintenance program. The joints had been recut and filled with a polysulphide sealant — a common joint filler used for its flexibility and chemical resistance. We marked the floor including lines that crossed multiple expansion joints.
Within four months, the marking had lifted cleanly from every expansion joint location — not the concrete sections, only the joint positions. Polysulphide sealants contain sulphur compounds that are incompatible with amine-cured epoxy adhesion systems. The epoxy primer bonds to the concrete but doesn't bond adequately to polysulphide — the polysulphide surface energy is too low for amine epoxy wetting.
The fix is to check the expansion joint filler type before marking any floor with recent joint repairs. If the filler is polysulphide, the marking needs to stop at the joint edge and restart on the other side — leaving a deliberate gap across the joint — rather than bridging the joint. A small gap in the marking at each joint is far less disruptive than lifting marking every four months.
Brendale is South Pine Road manufacturing and the northern Brisbane industrial corridor. TMR approved. Expansion joint filler type is confirmed on every Brendale facility with recent joint repairs — polysulphide joints require marking gaps rather than bridge-over treatment.

Frequently Asked Questions
Yes. Brendale South Pine Road manufacturing and industrial facilities are part of our northern Brisbane schedule. Expansion joint filler type confirmed on every floor with recent joint repairs — polysulphide triggers marking gap protocol. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability insurance. Every Brendale quote includes a site assessment, surface condition report, and fixed pricing. No estimates that change at invoicing. For Workplace Health and Safety QLD improvement notices we can typically assess within 24 hours and deploy within 48-72 hours. Completion comes with photo documentation, a compliance statement, and material specifications. TMR approved for any road or carpark marking that requires local council or state road authority sign-off.
Polysulphide sealants contain thioether and disulphide groups that reduce surface energy and interfere with the amine curing mechanism of two-pack epoxy adhesion systems. The epoxy primer cannot achieve adequate wetting and bonding on polysulphide surfaces. Standard polyurethane joint fillers are generally compatible with epoxy; polysulphide is not. Surface preparation is assessed before every Brendale warehouse job, not assumed. That means checking moisture content, surface pH, contamination, and existing coating compatibility before a product is specified. We've completed 5,000+ warehouse and industrial floor marking jobs since 2009, and we carry $20M public liability insurance. Completion documentation includes product data sheets, application records, and compliance certification.
Ask the joint repair contractor for the product data sheet of the filler used. Polysulphide fillers are typically grey or black, slightly tacky to the touch when cured, and have a faint sulphurous smell if scratched. Polyurethane fillers are typically grey or beige, have a firmer, more rubbery feel, and no smell when scratched. If the original repair records are unavailable, a small solvent test (acetone on a cotton bud — polysulphide dissolves slightly, polyurethane doesn't) can distinguish them.
A 10-15mm gap at each expansion joint is subtle and looks intentional rather than accidental — it aligns with the visible joint line in the floor. It's much less noticeable than marking that lifts progressively from every joint over several months, requiring repeated spot repairs.
