How to waterproof MDF

MDF is a fantastic material that is relatively less expensive than many other alternatives, such as plywood. Its smooth and consistent surface makes it a great surface for painting and cutting detailed designs.

Highly versatile, MDF can be used for a number of different purposes including kitchen and bathroom furniture and window sills. It has a very consistent structure, which means any cut edges appear smooth and reduces the risk of splintering. However, when used in high humidity areas such as these it’s essential to ensure your MDF is waterproof and able to withstand moisture.

Waterproof MDF is available, though it generally comes at a much higher price than standard MDF. Waterproofing MDF yourself is a cheaper alternative and it’s relatively simple to achieve.

Making MDF water-resistant

What you need is a high quality wood varnish, sealant or stain – Ronseal Quick Drying Woodstain is a great option that is highly water repellent and able to withstand the threat of moisture and humidity. It also comes in a range of colours, so you can make the MDF look more attractive while adding a layer of waterproof protection.

Or, if you’re looking for more all-round, all-year protection for exterior MDF, it’s worth checking out the range of Sikkens products which also  guarantee protection from all elements, including sunlight.

Once you’ve got your ideal sealant, apply a few coats and you’re good to go. This is a great option for kitchens, bathrooms or exterior doors and will save you a lot of time, money and repair in the long run.
