What Is Medium-density fiberboard?

MDF Medium Density Fiberboard

Medium-density fiberboard, also known as MDF, is a wood product made from both hard and soft fibers. The “medium” in the name comes from the fact that it has more soft fibers than particle board but less than plywood. It’s typically very smooth on one side with an unfinished backside. It can be purchased in various sizes and thicknesses.

Uses of Medium-density Fiberboard

One of the most common uses for MDF is as a painted surface. You can find furniture, cabinets, and other items made from this material in retail stores.

It’s typically smooth on one side with an unfinished backside that allows you to paint it any color or design you want! While there are several different types of MDF, most can be painted with the same techniques.

Why Paint Medium-density Fiberboard?

What is Medium Density Fiberboard

Paint can be a great way to update the look of cabinets, furniture, and other surfaces in your home without having to spend a lot.

Painting MDF is also safer than sanding it because there are no sharp particles that could accidentally pierce or cut you as you work.

What to do Before Painting MDF

Sanding is not recommended before painting medium-density fiberboard. Sanding can create very fine, airborne particles that are harmful to inhale so it’s best to skip this step altogether. If there is old paint or varnish on your project, you should scrape it off using a putty knife to give the paint something to grip onto.

What Paint Should I Use?

Any latex or acrylic-latex paint should work well for painting medium-density fiberboard surfaces, but be sure to test it on a small area first. Follow the instructions on your can of paint and apply at least two coats for the best results. Allow each coat to dry completely before applying the next one.

What You Need to Paint Medium-Density Fiberboard:

To paint medium-density fiberboard, you will need the following tools:

Sanding block

For smoothing out the surface of MDF before painting. Sandpaper is not necessary for this step but can be used if desired.

Paint rollers and tray

Apply the latex or oil-based paints that are most commonly used on MDF.


For painting the trim work and other small areas that are hard to reach with a roller or paint pad. You can also use foam brushes for this step if desired, but it’s best to avoid them since they tend to leave air bubbles behind in the latex paints you will be using.

Drop cloths

To prevent paint from getting on the floor or other surfaces when the painting is in progress. It’s best to use old shower curtains, plastic tablecloths, newspaper, or sheets for this step if you don’t already have drop clothes lying around your house. You can also purchase inexpensive painter’s drop cloths from hardware stores if desired.

Paint tray liners

These are very helpful for keeping paint off of the bottom of your paint trays so you can reuse them later on other projects. They will also help protect surfaces underneath where you are painting, but they aren’t absolutely necessary to complete this project successfully.

Latex or oil-based paints

This type of paint is best for painting medium-density fiberboard because it adheres well to the smooth surface. Latex paint dries quickly and tends not to leave brush strokes behind which is desirable when working with MDF. Oil-based paints penetrate deeper into the material, making them very durable.

 Paint rollers

It’s best to use foam or synthetic fiber paint roller covers for this type of project because they grip the MDF more easily than natural bristle options. You will also want to make sure you get enough paint on your roller cover so that it glides smoothly over the surface, but not so much that it drips off.

 Paint striping pad

This is a small foam paint roller cover that has rows of bristles. It’s great for painting straight lines or getting into tight spaces because it allows you to hold the brush at an angle without getting your hands in the way. You can also use this type of tool with latex paints but other types of paint rollers may be better for this job.

 Paint stir sticks

These are used to mix up the contents in your paint cans so they have a uniform consistency before you start applying them to your project. You can also use clean popsicle sticks or plastic spoons but make sure there aren’t any sharp edges on them before you get started.

Shop vacuum

You can use a wet/dry shop vacuum for this project if desired, but it’s best to have an upright model with bags so the paint doesn’t clog the motor or other parts of your machine when in use. If you don’t already own one, they are relatively inexpensive and available at most hardware stores.

What to keep in mind when Painting MDF

  • It’s not recommended that you use water-based paints on MDF because they can cause damage, peeling issues, and moisture problems.
  • Painting requires a lot of patience so don’t get discouraged if your first couple of coats isn’t perfect.
  • Taping off edges and painting small areas at a time can take longer, but it’s the best way to get good results when you want them.
  • MDF takes 24 hours after applying paint before it will be finished enough for use in rooms without protective sealants applied on top of it.
  • Always use a primer before painting MDF.
  • MDF can be painted in any color available but don’t forget to seal it first for protection from moisture and other damage.

Once you have all of the tools that are necessary for painting medium-density fiberboard, it’s time to get started with your project.

   Shop Vacuum or Damp Towel

  •  Remove any loose debris from the surface using a shop vacuum or damp towel. You can also use tack cloths if desired but they tend to leave behind fibers that aren’t good for air quality so it’s best to use them sparingly.

   Sanding Block or Medium-grade sandpaper

  • Use a sanding block or medium-grade sandpaper on the surface of your MDF before painting if desired, but this step is not necessary for completing the project successfully. The paint will have little grooves in it when you are done which makes the piece look more natural, but it will work just fine without the sanding step.


  • Stir paint cans thoroughly before starting with your project if you are using latex or oil-based paints because they have a tendency to settle in the bottom of the container over time. It’s best to apply medium coats rather than thin ones so there aren’t any drips or runs to contend with.

   Paint roller trays

  • Use your paint roller trays, painting pad, and stir sticks along the way so you don’t have to stop in the middle of your project. You can use old shower curtains, plastic tablecloths, and newspaper sheets for this step if you don’t already have drop clothes lying around your house.


  • Allow the paint to dry completely before applying another coat. You can purchase small fan-style or battery-operated fans if you want to speed up the process, but this isn’t necessary for completing your project successfully. If you choose not to prime MDF prior to painting it with latex paints, allow at least 24 hours of drying time between coats.

   Protective sealant

  • When your paint job is finished, allow the final coat to dry for at least 20 minutes before applying polyurethane as a protective sealant on top of it if desired. If you want more shine, use high-gloss varnish instead and apply two thin layers with drying time in between each one.
  • Once the final coat is dry, remove any tape or plastic drop cloths from your project and allow it to sit for at least 24 hours before using it in a room if desired. You can put decorative pillows on top of it when you are finished with your painting job if needed so they don’t get damaged while the paint is curing.

What To Do After painting MDF

After you have finished painting your MDF project, it’s time to consider what needs to be done with the piece afterward.

   Use a Fan

  • Use a fan or small heater near your paint job if desired for faster drying times.

  Paint-Covered Hands

  • You can use your paint-covered hands or other tools on the MDF if desired, but remember that oils from your skin may cause the paint to peel so it’s best not to touch it after you’ve completed your project.

  Seal MDF

  • Seal MDF with protective coats if desired before using it in a room because of its unfinished state otherwise. You can purchase polyurethane or high-gloss varnish at your local hardware store to use for this purpose.
  • MDF is not made of the same materials as wood, so it’s best to treat it differently than you would when working with other types of home supplies. Fortunately, sealing MDF with protective coats after painting doesn’t take very long and can be done in a few hours or less.

   Apply Polyurethane

  • All that you have left to do now is apply your polyurethane as a protective sealant on top of the MDF if desired. Allow it 24 hours before using it in a room for decorative purposes.
  • Handle MDF with care after painting because of its unfinished state and handleability issues. Apply protective coats when you are done for a finished look that will last for years. You don’t have to be an expert painter in order to successfully complete this project. All you need is to apply coats of paint carefully for the best results.

Sealing Materials to Use On the Edges of MDF

If you want to use MDF in a room, it’s best to seal the edges with some type of material beforehand. This will help to keep the MDF from chipping or peeling over time. You can purchase edge banding at your local hardware store or online which is specifically made for this purpose.

1. Edge Banding

2. Polyurethane

3. High-Gloss Varnish

4. MDF Sealant

Using Drywall Sealer to Seal Edges of MDF

MDF is a type of fiberboard made from wood fibers. It’s denser than particle board and has a smooth surface that’s easy to paint. You can use it for projects like shelving, molding, and cabinet doors.

Applying a coat of drywall sealer to the edges of your MDF will help create a smooth surface for painting. You can find this type of sealer at your local home improvement store. Once you’ve applied the sealer, let it dry for 24 hours before painting. This will give the sealer time to properly bond with

In case you’re painting MDF that will be exposed to moisture, you’ll also need to apply a coat of waterproof sealer. This will help protect your paint job from peeling or chipping if the MDF gets wet. You can find this type of sealer at most hardware stores. Apply the waterproof sealer according to the manufacturer

Advantages of Applying Drywall Sealer

Applying drywall sealer has a few advantages:

-It’s easier to apply than other types of sealants.

-It doesn’t require any special equipment.

-It can be applied in a short amount of time.

Disadvantages of Applying Drywall Sealer

-You may not get the same level of protection as you would with other types of sealants

  • You can use your MDF in rooms without sealing it.
  • You can get a natural look with no sanding required.
  • It’s much cheaper to paint MDF than wood.
  • You can paint MDF in any color you want.
  • You don’t have to be an expert painter in order to do this project.

Disadvantages of painting Medium-density Fiberboard

  • Painting a large project requires a lot of time and effort.
  • Take special care when using latex paints on MDF. They can cause damage to the material and cause peeling issues.
  • It’s difficult to get smooth surfaces when you don’t prime the wood first.
  • MDF doesn’t like any moisture at all, so water-based paints aren’t an option for completing your project successfully if desired.

Priming the MDF Fiberboard

Whichever paint you choose to use, it’s important that you prime the MDF first. This will help create a smooth surface for painting and prevent any damage to the material. You can find primers at most hardware stores. Apply the primer according to the manufacturer’s instructions and let it dry for 24 hours before painting.

Where to Buy Medium-Density Fiberboard

You can find medium-density fiberboard at most home improvement stores. It is typically sold in sheets and is used for a variety of projects, including shelving, cabinetry, and furniture.

When shopping for medium-density fiberboard, look for a product that is made with 100 percent recycled content. This will ensure that you are not contributing to deforestation.
