Providing a smooth surface appearance, Mapefloor I 302 SL is solvent and nonylphenol-free and is particularly suitable for flooring in the food industry. Abrasion and chemical resistant, it can be used as a paint or a high build coating, with quartz added to provide a low slip surface. It may also be coloured with 19 standard colours of Mapei Mapecolor Paste. Mapefloor I 302 SL is a FeRFA type 3 floor coating ideal for use in chemical and pharmaceutical industries, the food industry, automated laboratories and warehouses, aseptic areas and shopping centres.
All Mapei Mapefloor Systems offer distinct benefits; good abrasion resistance, a very strong bond to most substrates and are easy to maintain.
In addition to these functional qualities, they can also provide highly decorative surfaces making them the ideal flooring solution for a wide range of installations. The durable, dust-free resin surface offers versatility whilst providing an attractive finish.
Preparation of the substrate
The surface of concrete 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 for the types of loads acting on the flooring. The level of moisture in the substrate must be a maximum of 4% and there must be no capillary rising damp (check by testing it with a sheet of polythene). The surface of the floor must be prepared with suitable power tools (e.g. shot-blasting or grinding with a diamond disk) 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 defects present in the surface, such as holes, pitting, cracking, etc., must be repaired with Mapei Primer SN fillerized with quartz sand or made thixotropic with Additix PE, or with Mapefloor JA or Mapefloor JA Fast depending on the width and depth of the defects or cracks. Patch any badly damaged areas or joints, fill hollows in the surface, and repair or carry out localised variations to slopes with Mapefloor EP19, ready-mixed epoxy mortar.
Before applying Mapefloor I 302 SL, remove all traces of dust from the surface with a vacuum cleaner. The substrates must be primed and prepared as specified.
Application of Primer SN
Apply the Primer SN undiluted or mixed with Mapei Quartz 0.5 on the substrate with a straight trowel or rake after it has been prepared as specified. Immediately after applying Mapei Primer SN broadcast the surface while still wet with Mapei Quartz 0.5, depending on the type of resin system to be applied.
Preparation of the product
The two components which make up Mapefloor I 302 SL must be mixed together just before application. Stir component A thoroughly, pour all the contents of component B, and add the quartz sand when needed. Mix for at least 2 minutes with a suitable low-speed electric mixer (300-400 revs/min), to prevent entraining air into
the mix, until it 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 (it refers to a temperature of +23°C). Higher surrounding temperatures will reduce the pot life of the mix, while lower temperatures will increase its pot life.
Application of the product
Mapefloor I 302 SL can be used for non-slip multi-layer (0.8 to 3.5 mm thick) or self-levelling (2 to 4 mm thick) resin systems.
When the primer has hardened, remove any excess sand and carefully vacuum the surface. Mix the previously prepared Mapefloor I 302 SL with up to 50% by weight of Quartz 0.25 depending on the temperature and the thickness to be applied. The quantity of quartz sand to be added can be increased when the temperature and thickness increase. Mix to form a homogeneous mixture, then pour the product onto the floor and spread it out evenly with a notched spreader with “V” shaped notches. Back-roll the surface with a spiked roller several times while the product is still wet to remove any air entrapped in the product during the mixing phase.
