If you’re planning on varnishing your furniture made of cedar wood like a deck, patio furniture, or any table. And someone advised you to use linseed oil instead.
You might think for a moment, is this a good idea to use linseed oil on top of traditional finishes like varnish or a wood stain?
The answer is, Yes, linseed oil is one the most recommended finishes for cedar woods. For a reason that it thrives on humid weather and reduces the sunlight damage. Ideally suited for patio furniture as they need extra care from weather, so it is an ideal solution.
You can also use linseed oil for coating cedar wood in-door furniture. It’s more effective than many similar products: a non-toxic natural product that brings out natural texture, gives an aesthetic natural look, and also repels water drops, since it deeps down into a wood’s layer and gives a shiny topcoat to wood grains.
However, there are many varieties available in linseed oils as well. It’s really not a simple decision to make without knowing you cannot opt for the right one.
Although all linseed oils equally offer the same level of protection. But, the curing time is something that differs them. For example, the boiled linseed oil cures faster than normal raw linseed oil when used as a finishing coat.
Coats to apply:
Apply between five and twenty coats of the boiled linseed oil and Bio-OptionTM pure turpentine mix. A vigorous rub and wiping of excessive oil are required between each application. Between your first two coats, allow two days, and every additional coat should be a week or longer apart.
Many people think should they sand between oil coats.
Sanding between each coat is not necessary but that does not mean you should not. You can sand with grit for a better outcome but make sure you don’t force too much power so the wood’s surface will damage.
So, you should know that in the first place, both linseed oil and boiled linseed can darken a white wood, if you’re planning on coating on maple wood then you should try something other than this like a varnish with a light color.
Drying time of linseed oil on cedar
Drying or curing time largely depends upon the type of linseed oil used. In general, the raw linseed oil takes more time to fully dry which is 5-6 days. Whereas a boiled linseed oil only takes 2-3 days after applying.
Boiled linseed oil is basically just an altar form in which some drying agents are enclosed. Those ingredients boost up the curing process but also due to additive materials like petroleum. This becomes toxic up to some extent and emits VOC.
For Cedar: Why is Linseed the best oil?
You can find many alternatives to linseed oil, and perhaps you find something better and more effective than linseed oil. Anyways, when comparing the properties with some traditional finishes. You will find linseed oil topping the list because of its overwhelming capabilities.
Linseed oil has some qualities that are rare to see in other similar alkyd resins including, lacquer, polyurethane, and varnish as well. The qualities include its environmentally friendly nature and have no VOC.
Moreover, unlike other resins that get weak due to changes in weather: for instance in a humid environment the other products may start bleeding and with time the topcoat becomes yellowish. No such hazards are found in linseed oil, and it keeps for years without requiring any further action.
Why should you use linseed oil?
Let’s talk about some obvious qualities that linseed oil puts on the table while others do not.
So you can make the right choice by looking at the pros and cons of linseed oil vs other wood vanishes.
Pros and cons
|Linseed Oil||Other wood finishes|
|It emphasizes wood grain's depth of color and texture, an old-dull-looking piece of wood after applying the oil becomes shiny and cool.||Most of the common finishes require regular re-oiling to maintain the topcoat. Because with time, the topcoat gets weak.|
|If you apply linseed oil after, you can still remove scratches and dents by using sand grit paper.||Easily affected by water rings, they get yellowish due to changes in weather effects.|
|Contains no toxic chemicals and is eco-friendly. And also does not get yellowish nor peel off.||Changes in temperature or humidity may cause wood to “bleed” oil.|
|Effectively protects against changes in humidity and penetrates deep into the grain due to its less viscous property it saturates more into wood than other wood products.||Wood is more prone to stains if colored liquids penetrate.|
