But an old and dull deck can diminish your efforts.

You need to purchase the best decking oil in the market. We will show you how to make the right choice, one that will provide you with value for your money.

What You Need To Know

Decking Oil Buying Guide

The first advice we can give you is to consider the durability. 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. The sun and water would beat down on the deck, snow can pile up and also dirt and mildew spores would settle on the surface during the winter seasons.

These factors will affect the endurance of the decking oil depending on the quality. If you get cheaper, poor quality teak decking oil, with time, it cracks and causes mildew buildup. Only the best will last long regardless of the conditions they are exposed to and some also fend off the dirt. Read the reviews from people who have used the product, it will help.

Preservation properties also matter when choosing decking oil. The main purpose of decking oil is to provide protection of the wood against harsh environmental conditions. Well-Known teak decking oils brands like Ronseal, Cuprinol, Ipe, Holzol and Diall ensure that the decking oils they produce contains formulations that treat and protect the treated wood against staining, UV rays, mould and algae growth and become soak, water and dirt resistant.

Decking oil treatments with a clear finish give basic protection and allow the wood to turn grey naturally without splitting, warping, cupping or cracking. The coloured decking oil paints are advanced to protect the treated wooden boards against sun damage much better than clear decking stain or varnish.

Ultimate Protection Decking Oil By RONSEAL

How safe is the decking oil when in use is also a factor to consider because you don’t want the decking oil to affect your health or that of the pets and the people around you. The decking oil you get should meet environmental standards that call for lower volatile organic compounds.

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.

The type of wood will determine whether you use the decking oil or not. 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. Since decking oil is designed to protect timber without necessarily changing its look, it will do best on hardwood decking surface to retain a natural tan.

There is also the clear decking oil that retains the natural colour of your cupboard, or outdoor furniture and the colour tinted oil that adds character and gives the pine or oak wood a specific look. Depending on your project and preference, you would choose which chart will work best for you.

Decking Oil FAQs

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. Decking oil is best used if you want to leave the natural colour of the wood as it is.

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.
