Product Description

Mapei Mapefloor I 900 is a 2 pack epoxy resin based binder, used as a fixing primer or adhesion promoter, or as a binder when mixing resin mortar with consistency similar to a mortar screed.

Best Uses

Mapei Mapefloor I 900 is best used as a binder for epoxy mortar used to repair and/or form protective coatings on industrial floors, or as a primer before applying epoxy or polyurethane coatings. It is also suitable as an adhesion promoter for synthetic mortar floors or a binder for fluid mortar used to smooth over deteriorated substrates.

Mapefloor I 900 is a two-component, epoxy resin-based binder, made according to a formula developed in MAPEI’s Research & Development laboratories, and is used to obtain mortars with a consistency similar to a mortar screed for renovating old floors. Due to its special composition, Mapefloor I 900 may also be used on lightly humid substrates.

Application

Preparation of the substrate

The surface of concrete floors must be dry or slightly damp, clean and sound and have no crumbling or detached portions. The minimum compressive strength of the substrate concrete must be 25 N/mm² and its tensile strength must be 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 be subjected. 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 a suitable mechanical process (e.g. shot-blasting or a diamond grinding wheel) 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 coating, remove all dust from the surface with a vacuum cleaner.

Any cracks must be repaired by filling them with Mapei Eporip, while any deteriorated areas of the concrete must be repaired with epoxy mortar made from Mapei Mapefloor I 900 and quartz sand. Before applying Mapefloor I 900, remove all traces of dust from the surface with a vacuum cleaner.

Preparation of the product

The two components which make up Mapefloor I 900 must be blended together just before application. Mix component A thoroughly and add the contents of component B. Mix again with an electric mixer at low speed (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 prevent entraining too much air into the mix. Apply the mix within the pot life indicated in the 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. To realize an epoxy mortar, add a mixture of graded spheroid sand to the mix as soon as it has been prepared, such as Mapei Quartz 1.9 or coloured quartz sand or aggregates at a resin:sand ratio of 1:8 - 1:10 (recommended) up to a maximum of 1:13, and mix again to form a consistency similar to screed mortar.

Application of the product

Mapei Mapefloor I 900 may be applied with a roller and used as a primer for resin coatings. Apply 1-2 coats of the product with a medium-piled roller until the pores in the substrate are completely saturated. If the surface of the floor is rough or badly worn, make trowellable fluid mortar by fillerizing Mapefloor I 900 with up to 1:1 in weight of Mapei Quartz 0.5, depending on the roughness of the substrate. Spread a thin coat of mortar over the surface down to a feather edge with a straight steel trowel.

When used as an adhesion promoter for resin mortar coatings, apply an abundant coat of Mapefloor I 900 on the surface to be treated with a roller until the pores are completely saturated and there is a thin, even film of resin binder on the surface. Pour the resin mortar prepared as above on the product while it is still wet and spread the mortar over the surface in an even coat using an aluminium straight edge and suitable spacers to form the required thickness. While the mix is still wet, compact it and smooth over the surface with a power floater with suitable blades or manually with a smooth straight trowel. The thickness of the spacers must be approximately 20% more than the final thickness of the coating to compensate for the drop in the level of the mortar after the compacting and smoothing process.

The surface will be porous after this phase. To form a washable, impermeable and sanitizable surface with an even finish, apply at least two coats of epoxy resin with 100% solids content, such as Mapei Mapefloor I 300 SL, to fill and seal the pores. To form a non-slip effect, broadcast between the two smoothing coats with a suitable grade of quartz sand.
