Overview

• Great cohesion over any cement, wood or painted surface
• Complete waterproofing
• High resistance to abrasion and sun light UV rays
• Anti-slip and anti-bacteria
• Prevents the bacteria growth and formation of fungi
• 3 perfect finishing: GLOSS, MATT AND SATIN
• Easy application, bubbles free
• Use in walls and floors
• Ready for sport tracks

The CIMENTART Bi-COMPONENT POLYURETHANE is a waterproofing coating, made of aliphatic polyurethanes, of high resistance to washing and weathering (Comp A) and an aliphatic isocyanate without solvents (Comp B), recommended to be used over the Microcement coatings, concrete, printed concrete, polished cement and wood.

With the application of the CIMENTART Bi-COMPONENT POLYURETHANE, you achieve:

• Protection of the microcement coating, cement and wood.
• Enhancement of its aesthetic finishing.
• Three different finishing: gloss, satin and matt.
• Increased resistance to abrasion.
• Complete waterproofing of the surface.
• It allows to clean the surface where is applied, with any type of chemical product.
• Resistant to chlorhydric acid.

Technical data of the A + B mix

Use instructions

In absorbing surfaces, apply previously a layer of CIMENTART Sealer.

Mix the two components, using an electric mixer, until you get a perfect homogeneous mixture. Is done using the following proportions: 5 parts of Polyurethane (component A) to 1 part of Hardener (component B). It is important to mix completely the two components to avoid the appearance of areas of different grades of gloss due to a deficient dispersion of the two components.

To achieve an extra hardness and resistance to scratching, especially on pavements with heavy traffic of people or greater wear, you can make the mixture in the following proportions: 4 parts of Polyurethane (component A) for 1 part of Hardener (component B).

After the correct mixing is done you should filter the mixing using a metallic strainer.

Once the mixing is filtered if you notice the formation of small bubbles, you should wait 5 minutes before you start the application.

Apply one layer, in an orderly way without stretching too much the product, ensuring that no area is left uncovered, and without excesses, creating a layer of the thickness of a paper sheet. Cover very well all the areas with water contact and the joints where the water can penetrate.

In vertical areas make sure that the product doesn't not creates drops that slide down. Use the roller to fix the situation.

A too thick layer can produce:

• The products drops (in walls).
• A too slow drying.
• Decreased hardness due to excess of product. Remember that the recommended amount of product (once soaked in the roller), by m² is 60 to 80 g.

Apply a second layer exactly like the first. In areas with water contact, we recommend to apply 3 layers.

Before the application of the second layer of CIMENTART Bi-COMPONENT POLYURETHANE, make sure that the first layer is completely dry, approximately 8 to 12 hours, depending of the site ventilation and temperature.

This product needs good ventilation in the room where it is applied.

The life span of the product once mixed is about 1 hour, after that you will notice an increased viscosity and the hardener properties will be lost. Is recommended to use the mixed product in less than 1 hour.

The drying time before use the surface is minimum 72 hours. The minimum time of wait before put the surface in contact with water is 1 week.

The product is presented ready to use, we do not advise its dilution, which would cause loss of properties of hardness and waterproofing.

Apply directly with a varnish roller, a brush or an airless system over a dust free surface. We recommend brushing the surface after apply the product to remove possible air bubbles, especially on very hot, dry and highly ventilated site.

Clean all tools with water.

Drying times

The drying of the CIMENTART bi-component polyurethane depends on the temperature, ventilation and humidity.

Ultra violet ray resistance

CIMENTART bi-component polyurethane is an aliphatic product. It is completely resistant to the action of UV rays and does not yellow to the outside.

Resistance to chemical products once applied

*10 maximum score. 0 minimum score

Efficiency

With 1 liter of CIMENTART Bi-COMPONENT POLYURETHANE, you can cover approximately 15 to 20 m² of surface, depending on the absorption of the support and the thickness of the applied layer.

We recommend 2 layers on surfaces with no contact with water and 3 layers on surfaces with contact with water or humidity (exterior surfaces, shower plates, WC or kitchen worktops, etc.)

Recommended finishes

Floors: we recommend, without exception, that you apply on floors, interior and exterior, the CIMENTART Bi-COMPONENT POLYURETHANE GLOSS, for a better cleaning of the surface. The Matt floor many times gives to the customers the impression of being not-finished, old and dirty.

Walls: In walls, you can apply any of the 3 available finishes: Matt, Gloss or Satin, according to the customer choice.

Packaging

The CIMENTART Bi-COMPONENT POLYURETHANE for all types of finishing: Glossy, Satin or Matte is available in 3 different recipients:

• Recipient of 1 kg (0,83 kg of Component A + 0,17 kg of Component B).
• Recipient of 5 kg (4,16 kg of Component A + 0,84 kg of Component B).
• Recipient of 20 kg (16,7 kg of Component A + 3,3 kg of Component B).

Storing

12 months, in a dry place protected from bad weather, in original recipient hermetically closed.

Recommendations

Do not dilute the product with water or solvents.

Never apply the product on substrates that are wet, damp or have capillary moisture. Do not apply the product if there is a humidity in the environment of more than 50%.

Do not apply in layers greater than 0.1 mm. Respect the recommended drying times. A good ventilation is necessary in the rooms where it is applied.

Do not apply with risk of frost or rainy weather. Do not apply at temperatures below 5°C or above 35°C.

Never leave any of the layers in half, once the application is started, continue until its completion without stopping, so you do not see cuts, encounters or joints. If the surface is very large, several people must make the application at the same time.

Protect furniture, chairs or tables with protective felts.

Never drag furniture or other objects and protect the pavement if you are going to carry out other construction work on the pavement.

Merchandise considered not dangerous in matters of transport. It is water based, free of solvents, alcohols or flammable products.

Use the appropriate PPE, contains cement, and irritates the eyes. Do not place children within reach, avoid contact with eyes and skin through appropriate PPE. In case of contact with the eyes, rinse thoroughly with water and consult your doctor in case of subsequent discomfort.

Once the application is finished, let it dry completely and let it run for at least 4 days before doing other types of work and 7 days before moistening or receiving water.
