Osmo 420D

Deep Colour and Sheen Finish

Osmo 420D does more for decking than most oils. Though the can's relatively small size- and capacity-wise, the 2.5-litre can will have no issues covering up to 40 square metres. Also, you can choose between 0.75- and 2.5-litre drums. The first will let you cover somewhere around 15 square metres.

The product will make sure the wood doesn't crack, flake, peel, or blister. When you apply the solution after staining the wood, the product will be able to significantly prolong the renovation time. On the other hand, when used as a standalone finish, two coats will be enough to protect the wood from the greying process.

Setting the UV protection aside, the formula's active ingredients (dioxides) work wonders protecting wood against mould, algae, and fungi. Also, the formula makes the product completely transparent, so you can apply the oil onto any wooden surface, including windows, doors, cladding, fencing, and other vertically-structured joinery.

The only problem we have with this product is that the can is somewhat difficult to open and close.

Other than that, Osmo 420D makes no compromises. The solution is easy to apply. One coat will give you this nice matte finish, whilst the second coat will give the wood this deep colour with a sheen finish.

Using this solution, you'll have no issues reviving and restoring the wood's natural colour. At the same time, the oil will be able to enhance its beauty. Meanwhile, the formula's UV filters are able to reduce discolouration and fading from the sun, all whilst maintaining the deep and bright finish.

You can easily apply the product using most brushes/applicators. The solution will be able to protect most timber decking types, including fences, sheds, and hot tubs.

The formula is water- and dirt-resistant, so you can apply the solution whenever you want.

Ronseal 37299

Penetrating Deep

Ronseal 37299 Ultimate Protection Decking Oil provides, as you would imagine, ultimate protection. The product penetrates much deeper into the wood than most decking oils, increasing its durability.

At the same time, the solution applies this light tinted finish, giving the wood double the weather resistance and foot traffic protection compared to standard oils used for decking.

The long-lasting formula colours and waterproofs the deck simultaneously, so you won't have to apply more than 1-2 coats. Generally speaking, the solution becomes waterproof within 90 minutes. You'll be able to re-coat in 4 hours.

As it is usually the case with these oils, the product also incorporates UV filters that shield the wood from the sun and protect it against fading. You can apply the solution onto ridged and smooth hardwood and softwood decking. The product should only be used outside.

Its flaws are basically limited to the fact that the 5-litre can doesn't last as long as one would expect and won't let you coat more than 32 square metres.

Apart from that, Ronseal 37299 Ultimate Protection Decking Oil will restore the wood's natural look and make sure that the restored look lasts as long as possible.

Barrettine LCDT005

Minimising Flaking and Peeling

Barrettine LCDT005 has been specifically formulated to treat cabins and various wooden structures. Its finish will make most sheds, fences, and pergolas look like new.

The formula penetrates quite deep into the woods, reducing splitting and cracking. At the same time, the product makes sure to minimise flaking and peeling. Its sheen finish will make these woods as presentable as possible.

The formula's dirt- and water-resistant, so you'll be able to apply the solution without taking these elements into consideration. The UV protection that the product offers is quite solid too, reducing fading and protecting the wood against the sun's harmful effects.

Generally speaking, the solution will take somewhere between 1-2 hours to dry out and begin acting. It is not that thick though, so you'll sometimes have to apply multiple layers to see the full effect.

On the upside, the biocidal film preserver inside the product's formula will be able to prevent surface mould and algae.

All things considered, Barrettine LCDT005 will make sure to repel moisture and protect different wooden structures from greying and various elements. The 5-litre can will let you treat up to 40 square metres. Also, the can is as convenient as they come.

Cuprinol 5122415

Wastes Less Time

Cuprinol 5122415 makes sure to nourish the wood and protect against the weather at the same time.

The product will work wonders replacing natural oils and resins lost through weathering. The water-based solution is quite runny, so you'll be able to apply the solution using most paint sprayers. The lightly tinted finish that the solution leaves behind will revitalise the wood, making most wooden structures (especially sheds, fences, and pergolas) look brilliant.

Of course, we've seen similar properties before. The difference between this product and most decking oils is that even one coat will be enough to activate the solution's water- and dirt-resistant qualities.

In other words, the product will last and you'll have to spend less time treating and cleaning these surfaces.

The trade-off here is that the oil will usually take quite some time (somewhere between 3 and 6 hours) to completely dry out.

On the bright side, the UV filters that the formula incorporates will be able to prevent fading.

Long story short, considering the price, Cuprinol 5122415 is as brilliant and effective as these products come. The 5-litre can allows you to treat up to 40 square metres. The decking will look amazing and won't become even remotely slippery, making this anti-slip decking oil especially good for households with children.

What Are Decking Oils?

Wood is as noble as building materials come. Its positive properties are ample and abundant. Of course, there are downsides too. More often than not, wood requires upkeep and maintenance to make sure the structures constructed from it remain functional and presentable. Using these decking oils, you'll be able to do just that.

These solutions will let you revive weathered decking, revitalise wood stains, and bring back the wood's natural shine. More often than not, these oils are able to feed and protect the wood from different elements, including fungi, mildew, and mould.

That being said, these products are also usually able to prevent flaking and peeling. The best products also make sure to reduce splitting and cracking. Using these oils, you'll be able to shield various wooden structures from the UV rays, preventing fading.

Apart from that, these products usually make decking dirt- and water-resistant, so you're able to walk them without worrying about slipping and spend less time on maintenance.

You can use various tools to apply these solutions, including these paint edger tools.
