Sikafloor 264 — 2-Part Epoxy Roller and Seal Coat
Sikafloor 264 is a two-part, total solid coloured epoxy resin for roller coating and seal coat applications on broadcast systems. Suitable for normal to medium heavy-wear environments including warehouses, workshops, garages, car parks, and food industry facilities. With a compressive strength of approx. 108 N/mm² and HKHA/MTS specification compliance, it delivers exceptional mechanical performance. Requires priming with Sikafloor 161 or Sikafloor 156.

FAQ
What primer is required for Sikafloor 264?
Use Sikafloor 161 or Sikafloor 156 as the primer coat. The primer ensures optimal bonding between the topcoat and the concrete substrate.
What is the difference between Sikafloor 264 and Sikafloor 263SL?
Sikafloor 264 is a roller-applied epoxy that also serves as a seal coat for broadcast systems, while Sikafloor 263SL is self-levelling for smooth seamless finishes. Sikafloor 264 has significantly higher compressive strength (~108 N/mm² vs ~50 N/mm²), higher tensile flexural strength (~39.6 vs ~20 N/mm²), and meets a higher cleanroom classification (Class 4 vs Class 5).
How long before the floor can be used after application?
At +20 °C, the floor is walkable after approx. 24 hours, can withstand light traffic after approx. 4 days, and reaches full cure after approx. 7 days. Actual times vary with ambient temperature and humidity.
