Ronacrete RonaFloor Epoxy Primer

Ronacrete RonaFloor Epoxy Primer is a two pack solvent free primer for application to dry concrete and polymer screeded substrates.

Best Uses

Ronacrete RonaFloor Epoxy Primer is typically used to prime concrete before application of RonaFloor epoxy floorings, for
excellent adhesion and minimal pin holing from porous substrates.

• Use before application of Ronacrete RonaFloor epoxy floorings, for excellent adhesion and minimal pin holing from porous substrates
• Provides good adhesion to prepared concrete and polymer screeds
• Apply by medium nap lambswool roller
• Solvent free
• Low odour

Application

Substrate Preparation
To achieve optimal adhesion it is essential that RonaFloor Epoxy Primer is applied to structurally sound, clean and dry substrates. Surfaces must be prepared after making good any defects in the floor, ensuring that friable materials are removed and replaced. Concrete must be prepared by captive shot blasting or similar method to produce lightly textured, laitance free surfaces. Steel must be shot/ grit blasted to SA 2.5. Substrates must be cleaned to remove grease, oil and dirt. Substrates must be allowed to dry after washing. Substrates must be vacuum cleaned, to remove shot and other loose materials.

Mixing
Add the full contents of the B component to the full contents of the A component and mix with a slow speed drill and spiral mixing paddle (MR2 or MR3 type) for approximately 3-4 minutes. Transfer to a shallow paint tray immediately after mixing, or pour onto the floor, to control exothermic reaction and extend working time. Material must never be taken directly from the mixing vessel, to avoid the risk of unmixed material being used.

Application
Apply a single coat of RonaFloor Epoxy Primer by medium nap lambswool or mohair roller to the dry prepared substrate at 4-6m²/ kg/ coat. Further coats may be required on porous substrates to prevent blow holes. Allow to cure for approximately 24 hours at 20°C.
