Your Buying Guide To Decking Oils

A good decking oil will give you decking that looks great for years. It will also save you money in the long run because you’ll face fewer repairs due to water damage. Our guide gives you the essential tips to remember before you make that final choice.

What You Need To Know

Decking Oil Buying Guide


Since the decking is meant to be exposed to the outdoor environment, the decking oil should offer long-lasting effects to reduce the maintenance price.

Moisture Proof

Wood is prone to moisture-related damage. You’re looking at swelling, splitting, rot, fungi, and mould. A good waterproof decking oil can prevent all that.

Tinted Or Clear

Clear decking oil is better if you want to enhance the natural grain of your decking. A tinted oil is more suitable if you want to add a richer, golden look to your wood (when the wood naturally lacks this richness).


You need to make sure that the oil you choose will not adversely affect the health of you, your family, pets or your garden. Products that have high VOCs are linked to a couple of pollution, smog and respiratory problems that would lead to headaches and dizziness. Go for the brand that produces decking oils or deck sealant with a lower VOC value.

Wood Type

Double-check to see if the oil you like is suitable for the type of wood that makes up your decking. There are some coloured decking oils that would be used on both softwood boards and hardwood decking boards whereas others are best used on hardwood decking.


Q: What is better, decking oil or stain?

A: There is no much difference between a stain and oil. They both build a plastic-like layer over the deck surface that will seal and protect the timbers from weathering and foot traffic. However, a deck stain will improve the appearance of the deck by changing the colour of the timber, whereas a deck oil will just enhance the natural colour of the wood.

Q: What is the difference between decking oil and decking protection?

A: There is no difference between the two. Decking oil acts as a protection of the timber from different weather elements and against foot traffic and natural environmental elements.
