White Stain Colours - How Is It Different?

Rubio Monocoat is known for its wide range of colours available in the Oil Plus 2C product. Currently, there are 40 standard colours available!


If you are making wood stain colour samples and not sure what white colour to choose, here is the scoop on all of Rubio Monocoat's light/white colours.



Available Light Colour

The four whitest colours for Oil Plus 2C are: White 5%, White, Cotton White and Super White.


Five slightly 'off-white' colours leaning a bit more to the greyish side are: Smoke 5%, Smoke, Mist 5%, Mist and DC Smoke.


Lastly, a 'whitish' colour that leans a bit to the creamy/yellowish side is the colour Natural.



What Are The Differences Between The Rubio Monocoat Light/White Colours?


Pigment Difference

There are 2 major factors that influence each colour.


  1. Pigment colour: The colour of the pigment in the oil

  2. Pigment load: The amount of pigment in the oil

The difference between the light Rubio Monocoat colours is simply different pigment colour, different pigment load or a combination of the two.


It is obvious that the different colour names have different pigment colout in them. But it is also helpful to know that a colour with '5%' in the name means that it has less pigment load than its parent colour. Additionally, there is one colour, DC Smoke, where the DC stands for 'Double Content' of the pigment load found in its parent colour, Smoke.


For example, White 5% allows more of the wood to remain seen than the colour White (which has roughly twice the pigment load). The same goes for the Smoke 5% and Mist 5% vs the colour Smoke and Mist.


These 5% Oil Plus 2C colours are ideal for application on wood with a ring porous wood (open grain) like Oak, Ash and Elm when you desire just a hint of colour in the grain but still want to see the true colour of the wood species on the areas between the open grain (latewood).


The below image shows the white colours side-by-side applied, and as you may see, the colour 'Cotton White' has the highest pigment load when comparing those four white colours.

The Affect Of Wood Species On Colour

The way each white colour appears on wood is dependent on the colour of the wood species it is applied to. For example, when used on a whitish wood species like Maple or Birch, the differences do not appear as dramatic as when applied on a darker wood colour. See the differences on the images below where we are looking at birch plywood and a plank of mahogany. The mahogany is darker and shows the variations (the pigment load of white pigment) much more than on the birch plywood.

Water-Popping

Another option, if you desire more options in the white level (or what we sometimes refer to as 'opaqueness' or 'chalkiness'), is to water-pop the sanded wood. This process opens the wood grain more and allows more pigment to penetrate the wood. More pigment means more intense colour.



Additional Creative Opportunities


Keep in mind everything we have discussed so far is accomplished using one one application of finish. That single application gives you colour and protection!


If for some reason, you cannot achieve the desired white colour using only Oil Plus 2C colour, Rubio Monocoat still have an alternative option.


You may first apply an application of Precolor Easy, which offers three white colours; Nordic White, Alpaca White, and Mint White.


Precolor Easy is a waterborne pre-treatment option that requires to be finished with Oil Plus 2C. Nordic White is the whitest in colour while Alpaca White is a bit more of a greyish white. Mint White has a touch of green added to it, so it appears like a very light green/white colour in the can.



The Whitest Wood Finish Possible

This is an easy one, but it requires 2 steps.


The whitest look achievable using Rubio Monocoat uses Precolor Easy 'Nordic White' as a stain followed by Oil Plus 2C 'Super White' as the finish.



Neutralizing The Red In Red Oak

The below image shows the effect of adding a hint of green to a Red Oak (northern) panel. The Mint White colour is used to create a white base that neutralizes the pink undertones of the red oak. This is why green is added to the white since the opposing colour of red is green. Therefore, it helps to neutralize the red tones.

Next, Oil Plus 2C ' Cotton White' was applied over the entire panel. As you see, this application of Precolor Easy and Oil Plus 2C gives an excellent white colour. Just by itself, the Cotton White appears as pinkish white. Even if the Red Oak panel was water popped, it would not have been as white due to the red oak base colour.



Cerusing

Cerused look with a light base colour looks great and is always a show stopper. There is a great example of a cerused look using Nordic White and a custom dark finish to make the grain pop without sacrificing the light look of the wood board.
