Neodur Special - Aliphatic Polyurethane Coating

Surface Preparation (Concrete):

• Mechanically prepare the surface (e.g., grinding) to make it smooth and open-textured.
• The surface should be dry, stable, and free of dust, grease, oil, and loose materials.
• Remove loose material by brushing or sanding with a machine and vacuum.
• Fill all cracks and joints with an Epoxy Putty.

Surface Preparation (Metallic Surfaces):

• Ensure it's dry, free of dust, dirt, and any poorly adhering coatings.
• For rusty areas, consider applying our rust converter, Neodur Metalforce.

Priming:

• Apply Epoxy Primer on your substrate.
• This stabilizes the surface and seals pores for better adhesion.
• In cases of highly porous substrates, you might need an extra primer layer.

Application (Smooth Polyurethane Coating):

1. Mix the two components A & B and stir for 3-5 minutes.
2. Ensure thorough mixing, and then apply the mixture. Once the primer is dry, apply the first layer of polyurethane coating (Neodur Special).
3. Apply the second layer in the same way, about 24 hours later (consider atmospheric conditions).

Application (Anti-slip Polyurethane Coating):

1. Follow the same steps as for the smooth coating.
2. When mixing the final layer, include the anti-slip additive (Neotex® Antiskid M) at a ratio of 1.5-2.5%.
3. Stir well and apply it on the surface.

Application (Anti-slip Polyurethane Coating with Quartz Sand):

1. After priming and applying the first layer, broadcast Quartz Sand until saturated.
2. Remove loose grains after drying and sand any surface irregularities.
3. Seal with Neodur® Special, depending on slip resistance desired.

Special Notes (Important for Success):

• Avoid applying Neodur Special in wet conditions or during expected rain.
• Store components at suitable temperatures and mix them in the shade.
• Don't over-stir to avoid air bubbles.
• If a long time passes between layers, lightly sand the previous layer.

Remember to follow these steps for a successful DIY polyurethane coating application.

How should I prepare a concrete surface for this polyurethane coating?

• You'll need to mechanically prepare the surface by grinding it to make it smooth and open-textured. Ensure it's dry, stable, and free of dust, grease, oil, and loose materials. Fill cracks and joints with Epoxy Putty.
  

What's the process for preparing metallic surfaces?

• Ensure the metallic surface is dry, free of dust, dirt, and poorly adhering coatings. For rusty areas, consider using our rust converter, Neodur Metalforce.
  

Do I need to use a primer, and if so, which one?

• Yes, apply Epoxy Primer to your substrate. This stabilizes the surface and seals pores for better adhesion. Highly porous substrates may require an extra primer layer.
  

How do I apply the smooth polyurethane coating?

• Mix components A & B thoroughly and apply the mixture. Once the primer is dry, apply the first layer of Neodur Special. Apply the second layer about 24 hours later, considering atmospheric conditions.
  

Can I create an anti-slip surface with this coating?

• Yes, you can. Follow the same steps as for the smooth coating, and when mixing the final layer, add the anti-slip additive (Neotex® Antiskid M) at a ratio of 1.5-2.5%.
  

What if I want to use quartz sand for additional slip resistance?

• After priming and applying the first layer, broadcast Quartz Sand until saturated. Remove loose grains after drying and sand any surface irregularities. Seal with Neodur Special based on the desired slip resistance.
  

Are there any special precautions I should be aware of?

• Avoid applying Neodur Special in wet conditions or during expected rain. Store components at suitable temperatures and mix them in the shade. Be cautious not to over-stir to prevent air bubbles.
  

What surfaces are suitable for this DIY polyurethane coating?

• This coating is suitable for a variety of surfaces, including concrete floors, metallic surfaces, warehouse ramps, car ramps, and more.
  

How does this polyurethane coating perform in challenging conditions?

• It remains unaffected by UV radiation, weather conditions, and offers exceptional resistance to yellowing. It's highly durable, even under adverse conditions, making it ideal for industrial and parking areas.
