Hello everyone, I have a bigger challenge at home: I want to make my Ikea Malm furniture water-resistant because they show damage from moisture quickly in damp areas like the bathroom or kitchen. My question is: How exactly can you make Malm furniture water-resistant without significantly changing its appearance, and which materials or methods are especially suitable for protecting the wood and surface from water? If possible, please also include advice on surface preparation and which paint, sealant, or oil works best. Thanks for your tips!
Hey Nonkazim, good question! 🙂 Unfortunately, Malm isn’t the most water-resistant piece of furniture, you notice that quickly. If I were you, I would go for clear varnish or acrylic paint, as they offer good protection and hardly change the appearance. It’s important to sand the surface first so it can absorb the finish well – otherwise, the coating won’t adhere properly.
Just gently sand with fine sandpaper to create a matte surface, remove the dust, and then apply several thin layers of varnish. The more layers, the better the protection. Personally, I’ve had good experiences with water-based clear varnish, which also doesn’t have a strong odor. And don’t worry, it really becomes almost invisible. Oh, and always let each layer dry thoroughly before applying the next one ;-)

As a supplement: It is important to thoroughly prepare the surface first. Many underestimate the sanding, but especially with the smooth films often used by Malm, it is essential to ensure good adhesion of the paint. It is best to use sandpaper with a grit between 180 and 220.
I also recommend applying a wood fiber filler before the actual clear coat if the furniture piece has small scratches or uneven areas – this will create a smooth surface and allow the paint to absorb evenly.
Regarding the paint itself: A high-quality polyurethane clear coat is ideal because it is water-repellent, durable, and flexible. However, it is somewhat more expensive. If you want a particularly robust surface, you should apply at least three coats with light sanding in between (fine, about 320 grit).
One more tip: Treat the edges of the furniture first, as moisture often penetrates there first.
What type of use and moisture exposure do you have planned exactly? That could still influence the choice of paint type.

The furniture is placed in a small bathroom with moderate but consistent moisture (showers, water droplets on surfaces) and occasionally next to the kitchen sink, where splashes can occur. The surfaces are not expected to get completely wet; the main concern is protection against splashes and high humidity.

That will be almost invisible That’s good to hear, as I want to keep the typical surface and appearance without it looking shiny or "artificial."I’m still a bit unsure about the types of finishes; it would be helpful to understand the exact difference between acrylic paint and polyurethane clear coat — maybe you could provide a brief explanation?

What exactly is the difference between acrylic lacquer and polyurethane clear coat?Sure, happy to explain! Acrylic lacquer is based on acrylic resin, usually water-based, dries quickly, has less odor, and is well suited for interior use. It forms a thin, flexible protective layer, which is not quite as durable as polyurethane.
Polyurethane varnish, on the other hand, is tougher and more resistant to scratches, water, and chemicals. It often has a glossier finish and cures harder, but it takes longer to dry and has a stronger smell. There are also water-based polyurethane options that are somewhat milder.
So, if you want something simple and visually unobtrusive, acrylic lacquer is great. For areas like bathrooms and kitchens, which are exposed to moisture more often, polyurethane is better if you prioritize durability. 😉
One more thing: Always ensure good ventilation when applying any finish, no matter which one you choose!
I agree with the suggestions but would like to emphasize: the protective effect depends greatly on the application. Several thin layers with sanding in between are better than one thick layer.
For softwood furniture, I recommend applying a primer (e.g., a wood primer) after sanding and cleaning, before applying the paint. This greatly improves adhesion.
Additionally, edges and corners require special attention because this is where most moisture damage begins. These areas should be carefully sealed.
An alternative to paints are water-repellent oils or wax treatments; however, these are significantly less durable and often not ideal in damp environments.
My advice: it’s better to invest a little more in materials and work carefully—this way, the protection will last longer.
