Epo Paint is a two-component, fillerized epoxy resin-based formulation with high solids content and is used to form seamless, self-leveling coatings specific for clean rooms, and with good resistance to microorganisms. Epo Paint is also characterised by its good mechanical strength and good resistance to chemicals and abrasion. Epo Paint meets the requirements defined in EN 13813, which specifies the requirements for screed materials used for internal floors, the requirements of EN 1504-9 and the minimum requirements of EN 1504-2.
Field of Application
Epo Paint is a two-component, colored epoxy formulation with high solids content used to form smooth, self-leveling coatings on industrial floors. Once hardened, Epo Paint is characterized by the very low level of micro-particles and volatile organic compounds (VOC) it releases into the air. This characteristic makes it ideal for coating floors in areas such as clean rooms, where a very high standard of hygiene is required and where the size and concentration of dust particles and suspended micro-particles need to be monitored. Epo Paint, can maintain a close control on potential biological and physical pollutants that could affect processes in various sectors of industry, such as: · food and drinks;
· hospitals and operating theatres;
· pharmaceutical, etc.
COVERAGE / CONSUMPTION
Preparation of the substrate
The surface of concrete floors must be dry, clean and sound and have no crumbling or detached areas. The compressive strength of the concrete used for the substrate must be at least 25 N/mm² and its tensile strength must be at least 1.5 N/mm². The strength of the substrate must also be suitable for its final use and the types of load to which it will undergo. The level of moisture in the substrate must be a maximum of 4% and there must be no capillary rising damp. The surface of the floor to be treated must be prepared with a suitable mechanical process to remove all traces of dirt, cement laitance and crumbling or detached portions, and to make the surface slightly rough and absorbent. Before applying the product remove all dust from the surface with a vacuum cleaner. Any cracks must be repaired by filling them with Epoinject, while any deteriorated areas in the concrete must be repaired epoxy mortar. Apply primer as is or mixed with Quartz 0.5 on the substrate after it has been prepared as specified with a straight trowel or a rake. Immediately after applying primer, lightly broadcast the surface while still wet with Quartz 0.5 at a rate of 0.5 kg/m²; we advise against exceeding this consumption rate. Make sure there are no open pores in the surface of the substrate, otherwise air bubbles could escape and form small craters or pinholes in the self-leveling finishing coat.
Preparing the product
The two components which make up Epo Paint must be blended together just before application. Mix component A thoroughly and add the contents of component B. Add around 30% by weight of Quartz 0.25 and mix again with an electric mixer at low-speed to prevent entraining air into the mix (300-400 revs/min), for at least 2 minutes until the mix is completely blended. Pour the mix into a clean container and briefly mix again. Do not mix the product for too long to avoid entraining too much air into the mix. Apply the mix within the pot life indicated in the data table (refers to a temperature of +20°C). Higher surrounding temperatures will reduce the pot life of the mix, while lower temperatures will increase its pot life.
Applying the product
Pour Epo Paint on the surface of the floor and spread it out evenly with a smooth or notched trowel with “V” shaped. Using a notched trowel allows the thickness of the layer and the consumption rate of the product to be controlled more easily. Go over the surface with a spike roller several times while the product is still wet to even out the thickness of the coat and to remove any air entrained into the product during mixing.
