Epoxy resin for balconies is a popular solution, but it's not UV-resistant, which can lead to yellowing and degradation when exposed to sunlight. In these cases, only epoxy primers such as Neopox® Primer WS and Neopox® Primer AY . Polyurethane coatings are better suited for the final balcony finish.
What is epoxy resin?
Epoxy resin is a synthetic polymer formed by reacting epoxies with hardeners. Once cured, it creates a hard, durable coating with high abrasion resistance. However, it is not UV-resistant, which limits its use on balconies.
What properties does epoxy resin have?
High adhesion – adheres perfectly to concrete substrates.
Chemical resistance – withstands contact with many chemicals.
Mechanical resistance – it is hard and abrasion resistant.
Lack of UV resistance – may turn yellow, chalk and lose its properties when exposed to sunlight.
Why is it suitable for balconies?
Epoxy resin can be used on balconies, but only as a primer for polyurethane or polyurea coatings. Products from the TrokenTech , such as Neopox® Primer WS and Neopox® Primer AY , provide excellent adhesion and durability.
Types of epoxy resins for balconies
Only epoxy primers are used on balconies, such as:
Provides very good adhesion and surface protection against rising moisture,
Used under UV-resistant top layers.
Advantages of epoxy resin for the balcony
Resistance to weather conditions
Epoxy resin as a primer effectively protects the substrate against moisture and water, but requires a UV-resistant finishing coat. Neopox® Primer WS can be safely applied to damp substrates, ensuring adhesion for the topcoat. Neopox® Primer AY, protects the terrace floor against capillary water.
Aesthetics and ease of cleaning
Epoxy primers improve the appearance of surfaces and increase the durability of topcoats applied to balcony and terrace systems. They provide adequate adhesion for coatings such as Neodur® FT Elastic, Neoproof® Polyurea R , and Neodur® Special .
High durability and mechanical resistance
Thanks to the use of an appropriate epoxy primer, the final coating remains highly resistant to abrasion and damage.
How to prepare a balcony for epoxy resin application?
Surface cleaning
All dirt, grease, and dust must be removed to ensure good primer adhesion. If the floor has greasy stains, degrease it using surfactants. If this method fails, mechanical cleaning may be necessary.
Repairing cracks and unevenness
Cracks in concrete should be filled with a suitable repair material, such as Epoxol® Putty , Epoxol® Liquid , or Neodur® FT Putty . Alternatively, you can make your own repair compound using Epoxol® Primer SF-P, mixed with quartz sand. However, it is recommended to use a primer on a damp substrate, such as Neopox® Primer WS , before applying resin repair compounds.
Application of epoxy primer
Neopox® Primer WS or Neopox® Primer AY is applied to the dry and cleaned surface , which ensures excellent adhesion to subsequent finishing layers.
How to Apply Epoxy Resin to a Balcony? Step by Step
Mechanical mixer or drill/driver with a mixing tip.
Soil application
The primer must be thoroughly mixed and applied evenly to the surface. To do this, combine the two components – the base and hardener – in the specified ratio, then mix with a low-speed mixer for approximately 2-3 minutes. This is crucial, as the entire mixture must be thoroughly mixed to properly distribute the hardener. Mixing at low speed minimizes air entrapment and the appearance of bubbles on the floor during application.
Finishing layer
Once the primer has dried (according to the manufacturer's recommendations), a UV-resistant coating is applied, such as Neodur® SpecialNeodur® FT Elastic , Neoproof® Polyurea R with Troken Stone are also suitable . At this stage, a wide range of solutions is available, tailored to individual design needs.
Summary
Epoxy resin for balconies is an excellent solution, but only as a preparatory primer. Products from the TrokenTech portfolio, such as Neopox® Primer WS and Neopox® Primer AY , provide durability and surface protection, but the top layer should be made of UV-resistant materials, such as polyurethane coatings. By carefully selecting the right products, you can achieve a durable and aesthetically pleasing finish on your balcony.
A two-component, cold-applied polyurea waterproofing membrane for roofs, terraces, or balconies. Rainproof within 1 hour of application. It prevents moisture absorption and seals. Resistant to UV radiation and mechanical damage.

Neoproof Polyurea R liquid roof membrane is root resistant (according to CEN/TS 14416:2014 ), external fire resistanceEN 13501-5 . Polyurea R is classified as Broof (t1) and has certified "cool roof" properties (Cool Material ).
NOTE: THIS IS A WATER-BASED PRODUCT. Select temperature-controlled shipping to receive your product on the promised date, regardless of weather conditions. Standard shipping may be delayed due to temperatures below 5°C encountered along the delivery route.
A two-component putty for a wide range of applications. Depending on the mixing ratio, a flexible, hard, or very hard mass can be obtained. Recommended for metal, concrete, wood, and ceramics. Also suitable for automotive and yacht repairs.
A putty for filling small holes or larger surfaces. It has greater plasticity than Epoxol Putty. Depending on the mixing ratio, three degrees of elasticity can be achieved.
TrokenPox Accelerator is a specialized primer additive designed to accelerate the curing process of epoxy resins. It shortens epoxy curing time by up to 6 hours, even at low temperatures.
A two-component, solvent-free epoxy primer for dry and oiled concrete substrates. It strengthens the substrate, creates a bonding layer, and adheres perfectly to concrete surfaces.
How to care for a balcony covered with epoxy resin?

If the balcony is finished with a UV-resistant coating, its maintenance is limited to washing with water and a mild detergent.
Epoxy or polyurethane resin for the balcony?
keyboard_arrow_downkeyboard_arrow_up
Epoxy resin is used only as a primer. Polyurethane resins, which are UV-resistant, should be used for finishing balcony surfaces.
Is epoxy resin UV resistant?
keyboard_arrow_downkeyboard_arrow_up
No, standard epoxy resin is not UV-resistant. There are some exceptions where epoxy has additional UV filters added, but this is not standard. Therefore, only epoxy primers are used for balconies, and the topcoat should be made of UV-resistant materials such as polyurethane or polyurea coatings.
How much does epoxy resin application cost?
keyboard_arrow_downkeyboard_arrow_up
The cost depends on the balcony area and the materials used. The average price of an epoxy primer is around 50-100 PLN/m², while a final polyurethane finish costs around 100-300 PLN/m².
