Sikafloor-261 CA

Size - 10L 

Sikafloor®-261 CA is a two-component, solid colour, high solids, silicone-free, low-viscosity, self-priming, glossy epoxy resin available in an unlimited colour range. Typically installed as a seamless, high build, smooth coating for light to medium duty traffic areas. This general service epoxy coating demonstrates good mechanical and chemical resistance. Final surface appearance options include: unlimited colour selection and  integral cove base.  Sikafloor®-261 CA is also used as a resin component (primer, binder and top coat) for high performance Sikafloor® Morritex® Systems.

Sikafloor®-261 CA is a two-component, self-priming, high solids epoxy resin coating designed for smooth, seamless, glossy finishes. It is suitable for commercial, industrial, and institutional facilities such as clean rooms, food service areas, warehouses, manufacturing spaces, and retail environments. It is also used as a primer, binder, and topcoat in Sikafloor® Morritex® high-performance flooring systems.

• Primer: Sikafloor®-261 CA acts as its own primer, but for high-moisture substrates (>4% moisture), compatible primers include Sikafloor®-1610, Sikafloor®-81 EpoCem® CA, or Sikafloor® 22NA/24NA PurCem®.
• Base Coat: Sikafloor®-261 CA in primer thickness (5–8 mil WFT).
• Final Coat (Wear or Refresher Coat): Sikafloor®-261 CA applied at 12–25 mil WFT.
