Polyurethane is a multipurpose material that finds use in furniture, moldings, and even ornamental items. Even though it is resilient and long-lasting, painting it a new color will improve its appearance and guarantee that it complements your décor perfectly.
Selecting the appropriate paint is crucial for achieving a durable finish. Popular choices with unique advantages are silicone, latex, and acrylic coatings. You’ll get the best outcomes if you understand these options.
It is essential to properly prepare the polyurethane surface before painting. By using the proper technique, you can guarantee that the paint sticks well and has a polished, even appearance. We’ll walk you through the process of getting ready, choosing the appropriate paint, and applying it successfully in this post.
Why paint polyurethane
Prior to selecting and using paints, you should determine whether this process is important enough to bother with.
Experts disagree on this issue in a number of ways:
- Of course, polyurethane itself looks good, however, it attracts dust and dirt well, which is difficult to remove from porous stucco. Caring for the painted surface is much easier.
- If we are talking about baseboards and moldings, then no matter how carefully their installation is carried out, there will definitely remain joints between the panels, especially at the corners. You can get rid of them using putty, which is hidden under a layer of paint.
- And the last thing is, of course, the decorative properties of the painted surface. Finished stucco looks much more attractive, not to mention the ability to give the product any shade or simply paint it, for example, bronze or gold.
These justifications are sufficient to help one decide in favor of painting.
Paint selection
Since polyurethane dissolves when exposed to white spirit or other similar solvents, the choice of dye for the material should be made carefully. Paints must therefore be water-based.
These comprise the subsequent categories of compositions:
- Acrylic;
- Latex;
- Silicone;
- Mosaic.
Let’s now examine these dyes’ characteristics and attributes in more detail.
Paint in acrylic (Be clear: these paints are not fire-retardant for metal Polistil.)
Acrylic coatings
Polyurethane, which is based on acrylic resins, is typically finished with acrylic paint.
The following factors contribute to this coating’s great popularity:
- The paint is absolutely odorless and harmless to the body, as, in fact, are all other water-dispersion compositions. Therefore, you can paint in residential premises without fearing for your health.
- The coating turns out to be matte, which allows you to give the finished surface the appearance of gypsum stucco.
- Such paint for polyurethane withstands wet cleaning well.
- It is resistant to temperature changes.
- It forms a coating that is quite resistant to mechanical impacts.
- It is distinguished by its durability.
- Low price, compared to other types of water-dispersion compositions.
That being said, acrylic paint is a simple choice when painting polyurethane foam.
Counseling! Polyurethane is frequently painted with fire-retardant acrylic coatings because it is a flammable substance. Nevertheless, all metal communications and the remaining finishing surfaces must be treated with fire-retardant compounds to ensure dependable passive fire safety in a house. You can use specific fire-retardant paints for metalPolistil for the latter.
Latex paint
In addition to their superior performance attributes, latex coatings stand out for the following reasons:
- Moisture resistance – the coating is not afraid of direct water ingress.
- High wear resistance.
- Looks attractive – unlike acrylic coating, it can form a glossy surface.
Silicone
The best performing paint for polyurethane stucco is silicone paint. Its primary benefit is that it practically never gets dirty thanks to its dirt-repellent qualities. The composition also possesses all the benefits of the two materials mentioned above.
The cost of silicone coating is its only drawback.
Whether painting polyurethane with silicone, acrylic, or latex, the key to success is selecting the appropriate paint type and properly priming the surface for a smooth, long-lasting finish. To achieve a long-lasting professional look, this entails choosing a paint that adheres well to polyurethane, priming and cleaning the surface appropriately, and applying the paint using the proper technique.
Painting technology
The most common questions are usually about painting polyurethane moldings and ceiling plinths on your own.
There are two ways to complete this task:
- Before installation – this option is, of course, much easier than finishing after installation. However, in this case, it will not be possible to hide the cracks at the joints.
- After installation – this process is more complicated, but it allows you to pre-fill and get a continuous surface.
We will take into consideration the second option since it is typically chosen.
Polyurethane molding puttying
Preparation
Base preparation is necessary before painting polyurethane moldings.
The following order is followed when performing the work:
- The surface must be thoroughly wiped from dust.
- Next, the cracks are sealed with putty. In this case, you should also pay attention to the gaps between the wall and the molding being finished.
- Then all surfaces adjacent to the molding must be protected from paint contamination; for this you can use masking tape. Furniture and floors should be covered with oilcloth.
- The final stage of preparation is coating the polyurethane with a primer, which will improve adhesion.

Painting
You can begin painting after the surface has been prepared. It is best to use an ordinary brush for these purposes.
Here’s how the instructions appear:
- The first step is to prepare the paint – stir the composition and, if necessary, add color.
- The coating is then applied in an even thin layer.
- After the first layer of paint has dried, the procedure can be repeated again.
Counseling! Painting polyurethane moldings typically constitutes a component of the room’s overall finishing. In this situation, it is important to consider the paint composition quality for other surfaces in order to avoid having to repeat this process too soon. This is particularly true for metal communications, which require the use of trustworthy coatings like Zinga conductive paint because they are prone to corrosion.
| Step | Description |
| 1. Choose Paint | Select a paint suitable for polyurethane surfaces, like acrylic, latex, or silicone-based paints. |
| 2. Surface Preparation | Clean and sand the polyurethane surface to ensure the paint adheres well. |
| 3. Priming | Apply a primer designed for use on polyurethane to create a smooth base for the paint. |
| 4. Apply Paint | Use even strokes to apply the paint, allowing each coat to dry fully before adding another. |
| 5. Finishing Touches | Once the paint is dry, inspect the surface for any missed spots and touch up as needed. |
If you use the proper paint type and take the required preparation steps, painting polyurethane can be a simple task. The advantages of silicone, latex, and acrylic coatings vary, so the best option for your project will depend on its particular requirements. Silicone coatings are perfect for damp areas, latex is simple to apply and clean, and acrylic paints offer superior flexibility and adherence.
A smooth and durable finish are largely dependent on proper surface preparation. This include giving the polyurethane surface a thorough cleaning, lightly sanding it to improve paint adherence, and, if required, priming it. If these procedures are skipped, paint may perform poorly and peel or crack.
For optimal coverage, apply the paint in thin layers using even strokes. Here, patience is key. You’ll get a polished finish if you wait for each layer to dry completely before applying the next. Recall that investing the necessary time will pay off in the longevity and aesthetic appeal of your painted polyurethane surface.
