FAQs

What is MDF?

Medium Density Fibreboard (MDF) is an engineered wood product made from wood fibers glued together with resin under heat and pressure.

Can I use MDF outdoors?

No, MDF is not suitable for outdoor use as it is susceptible to moisture damage and will swell and degrade.

How do I cut MDF?

Use a saw with a fine-tooth blade. Support the board to prevent breakage. Consider using a scoring saw.

What kind of paint should I use on MDF?

Use a primer specifically designed for MDF, followed by your choice of paint. Water-based paints generally work well.

How do I seal the edges of MDF?

You can use edge banding, edge sealant, or paint to seal the edges and prevent moisture absorption.

Is MDF strong?

MDF is strong and stable but not as strong as solid wood. Its strength is adequate for many internal applications.

How do I store MDF?

Store MDF flat in a dry location to prevent warping or damage from moisture.

Can I use screws in MDF?

Yes, but pre-drilling is recommended to prevent splitting. Use screws designed for wood or MDF.

Troubleshooting

Edge chipping during cutting.

Use a sharp blade and support the board properly. Consider using a scoring saw or applying masking tape along the cut line.
