Polyurethane resin for the balcony

Polyurethane resin for the balcony is a modern solution that provides effective waterproofing and aesthetic surface finish. Thanks to its unique properties, it becomes an increasingly popular choice among the owners of apartments and houses.

What is polyurethane resin?

Polyurethane resin is a synthetic polymer material, which after applying creates a durable and flexible coating. She is valued for its excellent mechanical and chemical properties, which makes it an ideal material for outside use, such as balconies or terraces.

Properties of polyurethane resin

• Flexibility : adapts to substrate movements, minimizing the risk of cracks.
• Abrasion resistance : withstands intensive use and mechanical loads.
• Waterproofing : creates an impermeable barrier for water, protecting the balcony structure from moisture.
• Chemical resistance : is resistant to many chemicals, which ensures long -term durability.
• Resistance to UV rays : can be subjected to high sunlight exposure without yellowing or chalk. Thanks to this, the visual effect, as well as the physical properties of the coating itself, do not lose quality for years.

Differences between polyurethane and epoxy resin 

Although both polyurethane and epoxy resins are popular surface finishing materials, they differ in several key features:

• Flexibility : polyurethane resins are more flexible, which makes them a better choice to surfaces exposed to movements and vibrations such as balconies.
• Resistance to UV radiation : polyurethane resins show much more resistance to UV radiation, thanks to which they do not turn yellow and do not lose their properties under the influence of the sun.
• Application : epoxy resins are often used indoors, while polyurethane is preferred outside due to their resistance to weather conditions. The exception are epoxy soils such as Neopox® PRmer WS or Neopox® Primer Ay , which is applied for damp substrates. They can be used outside, because they are then covered, among others Polyurethane resin coatings.

Advantages of polyurethane resin to the balcony

High flexibility and resistance to cracks

Thanks to its flexibility, polyurethane resin can compensate for small substrate movements, which minimizes the risk of cracks and surface damage. An example of such a resin is Floortop 1K .

Hydro -insulation and protection against moisture

By creating a tight coating, polyurethane resin effectively protects the balcony against water penetration, preventing moisture -related problems such as mold or corrosion.

Resistance to UV radiation and weather conditions

Polyurethane resin such as Neodur® Special is resistant to UV radiation, rain, snow and variable temperatures, which ensures many years of durability and aesthetic appearance of the surface. In addition, dyed according to the RAL palette allows you to obtain a specific visual effect of permanent for years.

How to prepare a balcony for polyurethane resin application?

Preparation of the substrate is crucial to ensure the durability and effectiveness of the polyurethane resin coating. Here are the steps to take:

1. Assessment of the condition of the substrate

Check that the balcony surface is stable, clean and dry. It is necessary to remove all loose fragments, fats, oils and other impurities. In the case of oil stains, it is worth using a concrete degreasing agent - Sulfanol A.

2. Repair of damage

It is necessary to fill the cracks and cavities with appropriate repair materials to get a smooth and even surface. For this you can use ready -made repair masses based on epoxy such as EPOXOL® Putty , EPOXOL® LIQUID or a quick -drying Neodur® FT Putty . Alternatively, you can prepare a resinous repair mass yourself by adding to the ground, e.g. EPOXOL® Primer SF-P small quartz sand.

3. Grinding

Before applying resin, it is worth sanding the floor to ensure better adhesion of the resin to the ground. Depending on the thickness of the entire applied system, this quality of grinding should be selected. This is determined on the CSP scale.

4. Priming

The next step is to apply the right soil that will increase the resin's adhesion and provide better binding to the ground. In the case of Polish climatic conditions, it is difficult to bring concrete outside to the frequently required dryness 4%. That is why epoxy soil is used for moist concrete Neopox® Primer WS . In the case of terraces located on Earth, which do not have waterproofing from the ground, Neopox® Primer Ay , which cuts off the moisture pulling capillaries.

How to apply polyurethane resin to the balcony? Step by step

The process of application of polyurethane resin requires precision and appropriate tools. Here are the steps to take:

1. Preparation of tools and materials

All necessary tools, such as rollers, brushes, mixers and the right amount of chosen polyurethane resin, should be collected. The litter box, painting foil or additional buckets can also be useful to pour the resin.

2. Mixing resin

Mix the resin according to the manufacturer's instructions to get a uniform consistency. It is recommended to transfer the resin into a clean container after initial mixing so that the hardener on the walls is evenly distributed in the base.

3. Application of the first layer

After applying the soil and leveling the ground, the first layer of polyurethane resin is applied. The resin layer is spread evenly on the surface of the balcony, taking care of covering all areas.

4. Drying time

The first layer must dry in accordance with the manufacturer's instructions before applying the next layer. This will allow the coating to harden properly and create adequate adhesion for further elements of the entire balcony system.

5. Application of subsequent layers

Depending on the requirements, subsequent layers of resin are applied, ensuring the right drying time between them.
