I have seen several lessons where part of the material list is masonite or MDF as a canvas. As a woodworker, I know what MDF is, but didn't realize it could be used for fine art. Is it the same material? What is masonite board? How do you prepare them? I have only used stretched canvas and canvas board.

Oops! Should have googled first....MDF = medium density fibreboard.

Not at all, Annie. That's my point. Although these items are brought up on the sites, they don't really explain what they are or how to prepare them.

MDF is a mix of woods made into fibers then pressed together using binders, pressure and high temps. It comes in 4'x8' sheets that can be cut into any size you want.  It is smooth. You MUST wear a mask when cutting it, because it creates a very fine dust that is hazardous. You can purchase it where ever you buy lumber.

I have no idea what Masonite is.  I would like to know how to prep them and opinions on their use.

MDF and hardboard both need to be primed all over with something like Golden GAC 100 or an artist's PVA glue. You can then gesso the side you are going to paint on. Larger sizes can tend to warp so should be cradled on the reverse

Christina I think masonite is the same material they make pegboard out of.

I've only seen where artists have put gesso on the surface or used these surfaces to glue down a final piece whether it is canvas or paper.

I believe the Ampersand company is one of a couple if art supply manufacturers who use these materials to make scratchboard and other items.

I put a link in Lynn's question about waterproofing. That artist uses masonite and she has a video on youtube.
I would post it for you, but I am on my phone and it is too clumsy.

Hi Christina.  You must be a young thing! ;)  When I was growing up, EVERYTHING was made of masonite--doors, furniture and even some house siding.  I believe it was invented around the 1920s and was a cheap wood substitute, made something like MDF but first with a steam process and then with pressure to lock wood fibers together.  My mom gave me some masonite panels to paint on a few years back and I gessoed them a few times and they provided a very smooth surface for oil or acrylic.  I did a painting on one and it was much smoother than canvas.  I assume the artist Natalie is speaking of does this as her Resin finish is so thick and heavy that it does best on wood panels.  I think these types of panels would be good for Cassein as it can't be used on a ground that gives, I believe. The panels I have are thin, maybe 1/4 or 1/8th inch.

Thanks Natalie, Ray and Lynn, for the information. I think I may try something on an MDF board.


Lynn, I guess when your grand-daughter comes up and asks you, "Are you gettin' old, Mimi?' you know you are past the "young thing" stage! lol!  ;D

I love painting on Masonite?  For a while it was all I used. It's great for fine detail. Nothing worse than trying to paint a delicate birds eye and have a canvas bump in the wrong spot.  Here we can get 4 x 8 sheets and cut it any size you want.  Then I always prime it a few times first with regular house painting primer, being sure to seal the edges good. Then I gesso it 5 or 6 times.   A lot of work, but well worth it I think. 

Another advantage is you can paint on the back also.  I did this for Christmas presents.  Then when you have a change of season you just turn it over and veola! 2 paintings in one. :2funny:

Christina;  I paint on high tempered Masonite for my oils and acrylics.  My son is a cabinet maker and he uses Masonite for the back of cabinets.  He told me all I need to do is paint a cote of acrylic paint on the side I am painting on.  You apply it with a dense roller for an eggshell finish.  It works beautiful.  Kathy

Christina and other PB carpenters,
I wonder if, as a carpenter, you can give me your input on the following.

My daughter make a drawing of an animal, almost 8x4'.  She want me to cut the shape in a piece of wood, so far so good... I can do that.  But she wants to attached it to the fence at the end of the garden.

My question is, what is the best wood to live up to strong sun, rain, and freezing weather.  I understand none can in the end, but wonder what I should us for best resistance to harsh weather.

I was thinking of 5/8" plywood, smooth finish on one side, coated with that copper green solution... and then multiple coats of acrylic varnish spray if she goes with acrylic paints.  Should she use oil painting instead?

Someone (who barely know more then I do about wood) said only cedar would do, I that true?

Thanks for your comment/input.
Annie
Cheers, Annie
