The MARIPUR 7200 is a colored, one component, highly durable, aliphatic polyurethane thin-layer floor coating.
The MARIPUR 7200 is specially designed for use as a floor coating in external surfaces, providing high mechanical strength, high abrasion and chemical resistance. It is color stable, UV-stable and weather-stable so it can withstand the battering of the elements when applied outside.

The MARIPUR  7200 is using a unique curing system (moisture triggered), and unlike other similar systems it does not react with moisture (moisture-cured) and therefore does not form bubbles or blisters when applied in higher thicknesses.

Advantages

• Simple application (roller or airless spray).
• Decorative.
• Resistant to constant, heavy abrasion and wear conditions.
• Color stable and UV stable.
• Heat and frost resistant
• When applied does not absorb liquids or dirt
• Stops the creation of dust
• Gives a glossy and easy-to-clean surface
• Does not show the chalking effect of aromatic polyurethane waterproofing coatings
• Chemical resistant
• Maintains its mechanical properties over a temperaturespanof-20C to +90C

Uses

The MARIPUR  7200 is mainly used on concrete floors, on exterior or interior surfaces.
Due to its long lasting unchangeable properties is widely used for:

• Car parking areas,
• Show rooms,
• External and Internal Pedestrian Decks,
• Storage rooms,
• Warehouses,
• Factories, etc

Consumption

400 gr/m2 in two layers. This coverage is based on practical application by roller onto a smooth surface in optimum conditions. Factors like surface porosity, temperature, humidity, application method and finish required can alter consumption.

Colors

The MARIPUR 7200 is supplied in light grey, dark grey and beige. Other RAL colors supplied on request.

Application

Surface Preparation

The surface needs to be clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the membrane. Maximum moisture content should not exceed 5%. Substrate compressive strength should be at least 25MPa, cohesive bond strength at least 1.5MPa. New concrete structures need to dry for at least 28 days. Old, loose coatings, dirt, fats, oils, organic substances and dust need to be removed by a grinding machine. Possible surface irregularities need to be smoothened. Any loose surface pieces and grinding dust need to be thoroughly removed.
WARNING: Do not wash surface with water!
WARNING: Do not use a metal-ball blasting machine to grind the surface, because the heavy metal-ball impacts destroy the cohesion of the concrete surface and lower its stability.

Repair of cracks:

Clean cracks and hairline cracks, of dust, residue or other contamination. Fill all cracks with suitable putty. The next day smoothen the putty surface with a sandpaper or a mechanical grinder.

Absorbent surfaces

Prime absorbent surfaces, like concrete, cement screed and wood with the MARIPUR® 7000 primer, for the first layer by using a roller, brush or a spray gun.
After 2-3 hours (not later than 4 hours) and while the primer is still a bit tacky, apply the first layer, of the coloured MARIPUR 7200 coating.
Once again allow 3-4 hours for the coating to cure (not more then 4 hours) and apply the second layer of the coloured MARIPUR 7200.

Non-absorbent surfaces

Prime non-absorbent surfaces like metal, terrazzo, mosaic, power-floated concrete and ceramic tiles with the MARISEAL AQUA PRIMER (diluted 25-30% with water), for the first layer by using a roller, or a brush.
After 12 hours (not later than 18 hours) apply the first layer, of the coloured MARIPUR® 7200 coating.
Once again allow 3-4 hours for the coating to cure (not more then 4 hours) and apply the second layer of the coloured MARIPUR 7200.
Stir well before using. For best results, the temperature during application and cure should be between 5C and 35C. Low temperatures retard cure while high temperature speed up curing. High humidity may affect the final finish.

Anti-slip Finish

In order to achieve an anti-slip effect we need to evenly sprinkle corundum (or silica sand) on the first layer of MARIPUR® 7200while still wet. When the layer is dry, we brush off any excess aggregate and continue with the application of the second layer of the MARIPUR 7200.

Packaging

MARIPUR 7200 is supplied in 20 kg, 10 kg, 5 kg and 1kg pails. Pails should be stored in dry and cool rooms for up to 9months. Protect the material against moisture and direct sunlight. Storage temperature: 5-30C. Products should remain in their original, unopened containers, bearing the manufacturers name, product designation, batch number and application precaution labels.
