Before you paint your polyurethane treated surface, it’s very important to keep in mind that, regardless of which paint you choose, your paint will not stick unless the surface has first been primed.
Water-based primers such as latex or acrylic primers are not suitable for priming polyurethane surfaces, so you will need to make sure that you use an oil-based primer that is compatible with your paint.
Once you have made sure that you have taken the time to properly prime your polyurethane surface, the next step will be to paint the surface!
The good news is that there are a variety of different paints that will stick to polyurethane-treated surfaces, and all of them come with their own unique advantages.
To help you decide which type of paint is right for you and your polyurethane surface, we’ll briefly outline each one below:
Acrylic enamel paint is a type of fast-drying acrylic paint that is durable and features a glossy finish.
They are one of the most affordable paint options available that are compatible with polyurethane surfaces, and are also resistant to fading, peeling, and chipping.
They also do not tend to have overly strong fumes, which makes them a great choice for keen DIY’ers!
2. Oil-based enamel paint
The next type of paint that is compatible with polyurethane-treated surfaces is oil-based enamel paint, which is usually the most popular choice for polyurethane surfaces.
Oil-based enamel paints are most ideal for polyurethane surfaces that are going to be exposed to general wear and tear, as oil-based enamel is exceptionally resistant to chipping and fading.
3. Acrylic latex paint
Last but not least, the next kind of paint that can be used to paint over polyurethane surfaces is acrylic latex paint, which is similar to acrylic enamel paint.
The only major difference between the two types is that acrylic latex paint is ideal for painting over polyurethane surfaces that are outdoors, such as exterior walls of the house or garden shed.
How do you paint over polyurethane without sanding?
Regardless of whether you’re planning on painting a polyurethane or non-polyurethane surface, it’s very important to ensure that the surface is properly prepared so that the paint is able to properly adhere, as well as so you get a professional finish that will last you for a long time.
Though sanding is usually the go-to method for smoothing a surface, it isn’t the only way that a surface can be made flawless ready for the paint to be applied.
If you don’t want to sand your polyurethane surface, then the next best thing you can do is to get your hands on something that’s going to be able to create adhesion to help the paint stick – and that’s where an oil bond product comes into the picture.
In place of being sanded, an oil bonding product will be able to help prevent a newly-painted polyurethane surface from bubbling, cracking, or peeling over time.
Oil bonds can be used on all types of polyurethane-treated surfaces (including wood surfaces) in all areas of the home, including the bathroom, kitchen, as well as bedrooms.
The oil bond will be able to create a professional level of adhesion in the same way sanding would, all while helping to smooth the surface so that the paint will apply evenly for a flawless finish.
What happens if you paint over polyurethane?
Polyurethane is a type of resilient topcoat that is often put on top of surfaces such as cabinets, doors, and other wood surfaces to help protect it from scratches caused by general wear and tear.
Polyurethane can be painted on, although it’s worth noting that, if you do not properly prime it, then it’s highly likely that the paint that you have applied will be unable to correctly adhere itself to the surface.
For this reason, for the best results, we recommend using an oil-based primer before you paint your polyurethane-treated surface, as this will help give the paint a better surface to stick to, all while helping to prevent any stains from the wood from getting through the layers of paint and ruining the finish.
After you have applied the primer, you will need to leave it for around 8 hours so that the primer is able to dry, at which point you will be able to go ahead and add a second coat if so desired.
After your polyurethane-treated surface has been prepped and primed, all you will then need to do is make sure that it is smooth and free from bumps, and the best way to do this is by sanding it down.
After you have done this, you will then be able to begin painting it in the same way you would any other surface. It’s as easy as that!
