Impranol Oil for External Doors

Impranol oil is a tough, weatherproof finish made to keep external timber doors protected from the elements. Without a protective treatment, an exterior door can fade, swell or warp in the British weather — Impranol creates a micro-porous, water-repellent layer that guards against moisture while still letting the timber breathe. It's an ideal finish for our oak external doors and hardwood external doors.

As well as repelling water, Impranol protects against UV fading and fungal growth, helping your door keep its strength and appearance for years. It won't crack, blister or peel, and its translucent finish enhances the timber while keeping the look you chose the door for. It's easy to apply by brush or roller, whether you're sealing a new door or refreshing an older one.

For the best results, coat every face and edge before hanging and re-apply as the finish needs it — our guide on how to treat external wood doors walks through each step.
