Features and Benefits
RonaFloor Epoxy Primer MT is a two pack solvent free primer for application to surface damp or porous concrete and screeded substrates. RonaFloor Epoxy Primer MT is typically used to prime concrete before application of RonaScreed self smoothing cementitious screeds, for excellent adhesion and minimal pin holing from porous substrates.
RonaFloor Epoxy Primer MT may be applied to shot/ grit blasted steel before application of Ronafix polymer modified screeds to stair pans and other applications where deflection of steel is minimal.

RonaScreed FastDry Prompt – benefits and drying
RonaScreed FastDry Prompt (formerly RonaScreed 8 Day Overlay) is so-called because it is a fast-drying screed additive which enables a 50mm thickness of 3:1 sand/ cement screed to be overlaid with moi ...
