Conflow 500 top — floor mortar with increased abrasion resistance and the possibility of external use.
Conflow 500 top is intended for use both when creating new floors that have to withstand heavy loads in industrial premises, and when renovating old ones. It evens and smoothes floors for heavy traffic with increased abrasion in factories, factories, warehouses, showrooms, production halls, etc. Conflow top is used as a base coat, which is applied directly to a smooth base or to Conflow 100 BASE.
Advantages: Conflow 500 top is an effective, fast-curing leveling coating for floors that is applied mechanically (at an application rate of approx. 250 m2 per hour at a thickness of 6 mm). Under normal conditions, pedestrian traffic on the applied surface is allowed after 3-4 hours, light loads are acceptable after 24 hours, and full traffic after 3-4 days. Conflow 500 top is a combination of fast curing and drying with low shrinkage and high strength. Conflow top is dust-free, chemical-resistant and frost-resistant. Conflow 500 top floors are resistant to chemicals in petrol stations, salt and frost resistance, which makes them suitable for bridge construction.

METHOD OF USE:
Preparation of the base and instructions for use: The mortar is intended primarily for use on a concrete base. It is recommended to inspect the surface level before applying the solution. To obtain a high-quality finish, uneven surfaces must be eliminated with Conflow 100 STANDART. The substrate must have a peel strength of at least 1,5 megapascals if Conflow top is poured directly onto it, and at least 1,0 N / mm² if previously coated with Conflow 100 STANDART. Uneven substrates must be pre-coated with Conflow 100 BASE. Weak or soft substrates, such as asphalt, which can be crushed under high loads after the application of a self-leveling coating must be removed without fail. Joints, structural joints and cracks occurring in the original substrate must be treated separately when forming the pavement.
The surface of the base to be treated must be flat, dry, durable, free of dust, grease, oils, paints and putties dissolving in water at a temperature not lower than + 10 ° C and at a relative humidity of the ambient air not exceeding 70%; dust and debris must be removed from the surface with a vacuum cleaner. Concrete deposits and old coatings should be removed mechanically, that is, with a closed short-term blowing, foamy solutions and, if necessary, cleaned with metal brushes. Before pouring Conflow top mortar to improve adhesion, it is recommended to treat the surface of the substrate with SCANMIX dispersion. Porous and very dry surfaces should be treated with the dispersion 2 times.
Mixing and application of the solution: It is possible to carry out by gradually adding the dry mixture to water with constant stirring with a low-speed electric mixer (no more than 600 revolutions/minutes and at least 2 minutes until a homogeneous mass is formed) or a pump mixer. Before starting the pump and before flushing the hose, a little mild solution must be passed through the pump. For mixing, use only clean water at the rate of 6 liters per 25 kg of dry solution (24%). Overdosing on water leads to a deterioration in the quality of the finished floor. It is necessary to regularly check the viscosity of the mixed material using the flow test, bringing the flow diameter up to 140-145 mm. After performing a mixture fluidity test, it is necessary to test the solution for separation by examining the behavior of the mixture under study on a vertical plate.
The mixture should be used within 30 minutes, and the temperature of the material should be within +10 … 20 ° C. The properties of the material can deteriorate significantly if too cold or overheated dry mortar is used. Conflow top should not be used at a substrate temperature below + 10 ° C and an ambient temperature below + 10 ° C, in addition, the coating must be protected from the influence of cold for 48 hours after application. The humidity of the ambient air must be below 70%. Light ventilation is recommended during and after coating, however, do not use air conditioners for the first two days. Strong drafts and direct sunlight should also be avoided. When the coating hardens, no special protection is required.
Doorways, stairs, pipes and drains should be insulated with foam barriers; too large surfaces should be divided into separate spans during processing. The span width is determined by the pump volume of the equipment and the required thickness of the future coating, but usually should not exceed 8-10 meters. If it is necessary to fill wider rooms, it is necessary to make expansion joints. The optimum coating thickness is 6-8 mm.
CONSUMPTION OF MATERIAL: Depends on the processed surface. Typically about 14-16 kg dry mix is required to apply a 6-8 mm coating per 1 m2.
COATING APPLICATIONS: The ready-made mortar is applied to the surface through a discharge hose that moves over the surface with a constant step, which allows to provide a certain required coating thickness. ПUnder normal conditions, the Mixer-Pump forms a nominal 6-8 mm layer of material. The thickness of the layers can be adjusted if necessary by using more or less material, as well as by spraying from a greater or lesser distance. If dents and streaks form on the surface of the hose, the freshly applied material can be smoothed out with a serrated steel trowel. The semi-solidified material can be molded or removed, allowing the desired changes to be made as needed.
TOOL CLEANING AND PRECAUTIONS: All tools and equipment must be thoroughly rinsed with water immediately after work. Do not pour the solution and water after rinsing the instruments into the sewer pipes.
FINISHED SURFACE: The mortar can be used for industrial use without additional coatings, but to improve aesthetic properties, ease of cleaning, additional protection from chemicals, it can be coated with epoxy or polyurethane coatings, as well as concrete paints. Depending on the drying conditions, these coatings can be applied after 72 hours.

The characteristics of the hardened material are indicated after installation and holding at a temperature of + 23 ° C with an air humidity of 50% and a moisture content of 15%. The load calculations are given for a layer of 10 mm, but they depend on the temperature and humidity of the air when the solution dries, as well as on the amount of moisture in the base.
WATER RESISTANCE: After final hardening, Conflow top can withstand the influence of water. However, long term water impregnation can cause a decrease in strength of up to 30% of its normal value, with full restoration after 24 hours of drying.
