A technique question?  :confused:


Can I use masking fluid (Pebeo drawing gum) on a canvas under oil paint to keep a part of my drawing  :crazy2: ?


Josh :whistle:

You CAN NOT use masking fluid under oils. The only way to mask off with oils if you use clear cover or even masking tape.

Thanks Maryna, but I wanted to be sure so I made a test this morning and the masking fluid from Pebeo adhere pretty well on the canvas and is not disturbed at all by oil paint and a big brush. My painting will be very complicated and it is impossible to use masking tape and cut with a rasor blade without cutting the canvas under it.


Thanks again for the help


Josh

According to this website, it's possible when you just want to mask of your canvas, but when I read how to remove it, you will lose your detailed drawing too.  :idiot2:

Hello Germa,


Glad to know that you are so aware after your surgery and recovering.


I made a test on a small canvas 14 x 16 inches with the wet on wet technique using a 1 1/2 inche (37mm) and applying the liquid white oil plus 3 colors over my drawing protected with the Pebeo masking liquid and nothing was removed or painted. After I partialy removed the masking liquid and my test drawing was there with all the lines.
It is a not very well detailed boat on a calm sea with 2 flying birds.
When it is completly dry, I will remove the balance of the masking fluid to fid all my lines

You can remove it with your fingers...or


So, I can confirm that it does work :smart:  .


Josh  :yippee:

Hi Val and thanks for the comment.
I was looking at your pictures and I will ask you if I can borrow one of your brown pelican on your boat for my project.


If you ever have the chance to take a picture of Edgar the Egret sleeping on one leg,,, you know who is interested... :whistle: 


My girlfriend liked my first part so much that she wanted to have it completed for herself :knuppel2:   .  So, I gladly acknowledge :whistle:   , and add the clouds.....immediately, the boat to be finished this week she gladly said :tickedoff: .


Josh


Have a nice day,
Josh :painting:

it will work if your paint is very thin, but the minute you have body (thickness) to the paint it will not work.

Thanks Nolan,


Do you think that thick paint will rip off ? I think so but wet on wet background is very very thin and I mean only the background sky not the trees or rocks.

two reasons -
1) if the paint is thick you will paint over the masking fluid and not even be able to see it
2) the paint is elastic so will rip

Thin layer like you would use for portraits or sky could work.

Even though it takes longer to apply I prefer to use the clear cover for my masks

Thanks for the answer and as I do not have children, this is an item I never tought of.


Here is my test completed on this 12 x 14 inches canvas. The masking liquid did the job but, you have to wait until it is very dried.

Not easy to do small subjects on small canvas because I never did much.  O0

Great job Josh  :clap: :clap: :clap:

Just a little tip when doing reflections - the water looks wetter and more realistic if it isn't a perfect copy of the actual object. Squiggle the edges, and distort the reflection as though the water is rippling in the wind

I explain how to do it in THIS class and even though they are watercolour classes, Dennis does an awesome job explaining how to do it in this series HERE and HERE

PS - I hope you don't mind but I have split this off of your portrait course paintings into it's own topic as I feel a lot of folks will benefit from your experiment, but nobody will find it buried inside the portrait thread
