Moulding Paste versus Joint Compound Tutorial

Hi Everyone,

Today I am bring you a comparison blog about the differences between Moulding Paste and Joint Compound. I have seen a lot reciently on YouTube and different mixed media sites about the use of Joint Compound being used in place of Moulding Paste.

Here are the three completed pages:

 


I started this test with 3 of the same page bases, the same as I usually use, that is three gesso-ed 8 1/2 x 11 double pages.

Here are the products I used:



Page One
I used the Joint Compound on the first page in the centre, the top right and the bottom left. 


I dried it with my heat gun and it dried really quick and without any bubbling that you often see with moulding paste. It did dry a little lighter, but not as much as I would have liked.






I then added the spray mists. I left it to dry naturally.





Page Two
For this page I added the Moulding Paste in a diagonal line from bottom left to top right. 


Knowing that this Moulding Paste bubbles when heated to much with the heat gun, I left it to dry naturally.




I then added the spray mists. I then let it dry naturally.



Page Three
At this point I decided that for most of my pages the color of the Joint Compound was not really the look I wanted, I wanted the texture to be the same as the background.

I then added Joint Compound to the third page in the four corners to create a frame. 



I then dried it with my heat gun. Again it dried really quickly and without bubbling.



I then covered the entire page with gesso. I knew that some areas already had gesso, but I decided to do a complete coverage so there was no chance I would miss any. I then left it to dry naturally. I then added the spray mists. I allowed this sprays to dry naturally in pools of color, as I wanted the intensity of color for this page.



I then completed each page. 

In the end I noticed several differences between the Moulding Paste and the Joint Compound:

1. The color difference. The Moulding Paste is a soft white and the Joint Compound is a soft cream/light brown,

2. The Moulding Paste really soaked up and made the colors more vivid and the Joint Compound did not soak up as much color and soften the colors a little, and

3. Where I coated the Joint Compound with the gesso, it created a great surface on which the sprays sat and mixed.

In conclusion, the Joint Compound is fantastic when you add gesso to the top or where the soft creamy color is an advantage, like on kraft cardstock. And Moulding Paste is good for when you want to keep your colors more true and vibrant.

See you all again soon.

Love

P.S. As an after-thought I tried the Joint Compound on Kraft cardstock and was very pleased with the results.
