Raw Or Boiled Linseed Oil For Outdoor Furniture

Essential Guide to Raw or Boiled Linseed Oil for Outdoor Furniture

Linseed oil is a natural, plant-based oil extracted from flax seeds. When applied to wood, it enhances its durability, protection, and aesthetic appeal. Choosing between raw and boiled linseed oil for outdoor furniture is crucial, as each offers unique benefits and considerations.

Raw Linseed Oil

Raw linseed oil is unrefined and has a longer drying time compared to boiled linseed oil. It penetrates deeply into the wood, providing excellent protection against moisture and decay. Over time, raw linseed oil forms a hard, water-resistant finish that ages beautifully, developing a rich patina.

Pros:

Excellent penetration and protection against moisture.
Creates a rich, natural patina.
Affordable and easy to apply.

Cons:

Long drying time (up to several days).
Can darken the wood slightly.
May require multiple coats.

Boiled Linseed Oil

Boiled linseed oil is processed with driers, which accelerate the drying process. It forms a durable, flexible finish that protects against moisture and UV rays. Boiled linseed oil often contains additives, such as mineral spirits or solvents, to improve its drying time and brush ability.

Pros:

Fast drying time (a few hours).
Creates a hard, flexible finish.
Protects against moisture and UV rays.

Cons:

May contain solvents, which can release fumes.
Can slightly darken the wood.
More expensive than raw linseed oil.

Which to Choose?

The choice between raw and boiled linseed oil depends on the desired finish and the specific conditions the outdoor furniture will be exposed to.

Raw linseed oil is ideal for:

Outdoor furniture that is not constantly exposed to rain or harsh UV rays.
Furniture made from hardwoods, such as teak or mahogany.
When a natural, aged patina is desired.

Boiled linseed oil is suitable for:

Outdoor furniture that is exposed to frequent moisture or sunlight.
Furniture made from softwoods, such as pine or cedar.
When a fast drying time is required.

Application and Maintenance

To apply linseed oil to outdoor furniture, follow these steps:

Clean the furniture and remove any dirt or debris.
Apply the linseed oil liberally using a brush or cloth.
Allow the oil to penetrate for at least 30 minutes.
Wipe off any excess oil with a clean cloth.
Let the furniture dry completely before using it.

Regular maintenance is essential to prolong the life of linseed oil finishes. Reapply linseed oil every few months, especially if the furniture is exposed to harsh conditions. Cleaning with a mild soap solution is also recommended.

Conclusion

Both raw and boiled linseed oil offer effective protection for outdoor furniture. By understanding the unique properties and applications of each type, you can make an informed decision to achieve the desired results. Whether you prefer a natural, aged look or a fast drying, protective finish, linseed oil provides a versatile and environmentally friendly solution for your outdoor furniture.
