Please make some sense of this as it seems you wouldnt put oil ground under acrylic primer. The Old Masters painted on primed pieces of wood to create some of the oldest masterpieces in art history. interfere with the adherence of an aqueous size or ground (glue, acrylic but it would not be as important. Also, (and I know I am venturing outside my original question), I don'tunderstand the purpose of an oil ground. A PVA size, as I understand it, protects against SID (support induced discoloration). Priming front and back will stop the primer from warping the board, by evening the stress of each drying layer. There is a traditional fine art way to prepare a surface for oils, which to me is expensive and time consuming. Click ? All Rights Reserved. Gesso only the side youll paint on.

Ive never bothered. This does not delete the image from the library. Alkyd mediums and oil-based primers do not produce this effect. One moderator thinks it's okay to paint directly on the tempered hardboard with oils because they shouldn't degrade the support. This fill coat is applied with a precision roll coater that ensures penetration of the coating into the fiber of the board and creates a good bond between the board and the sealer. http://ampersandart.com/priming-with-oil-painting-grounds.php, Note, you *must* seal the wood before doing anything and the current recommendations for this is PVA glue. Wood that has been exposed to elements for thirty to fifty years and has not split in any way will most likely last forever. It sounds like youre not sealing the surface first?

you better be sure that the oil dont reaches the board or it will rot it. Is that preferable to painting directly without sizing? into the panel. That is one of the reasons when in the distant past I used them, I However, preparing a panel appropriately is important too. Once it cools, the wood pulp binds together through the natural resin in the wood to become a solid panel. So use any decent size product like GAC 100, Gamblins PVA or cheap white acrylic students paint. (theres more thorough preparations but acrylic gesso on the hardboard with oils will do) oh yeah thought about warping, it gets to be a problem with about 2 x2 where the thinner hardboard will flop around. It sounds like sanding, then sealing with GAC 100, then either painting directly on the sealed surface, or painting after adding gesso or oil ground is recommended. A denser panel in comparison will accept a smoother coating of primer, reducing the number of gesso layers needed to properly prepare a panel with a smooth painting ground. Choose between different arrangements of page sections. After those similarities, canvas and linen are quite different. Todays artists are fortunate in that manufactured panels are dimensionally stable enough to be cradled or braced. In talking to Golden Paints, gloss medium was recommended over GAC 100 for better sealing. While these early works were all painted on prepared solid wood panels, there are many more options available for artists today. With most wood products Free Water does not concern us regarding differential shrinkage and expansion of the wood product. Regardless of the surface chosen, properly priming before you begin to paint is crucial and understanding what you are working on is also important. The panel was then sanded and burnished until it was smooth and ready for painting. Comment below with your favorite and best surface for oil paints you enjoy using!

Right, my word of caution was not in reference to any destructive effect that the oil might have on the panel material, but rather because I have observed oil paint on bare hardboard leaving a pronounced oil stain and colors becoming dull and waxy as a result of the oil being taken up. Perhaps they are using the word ground instead of size the size layer being the barrier layer that keeps oil from penetrating the support. Save my name, email, and website in this browser for the next time I comment. I know there's debate over whether painting oils over acrylicsizing and ground is archival. The best surface for oil paints to work on regarding panels is arguably is an old piece of furniture or an old piece of wood, that has had a chance to acclimate itself to all kinds of environmental contamination, humidity, or pollution. Finally, different veneers will prime differently. Hi. It was then covered with layers of ground made by mixing gypsum (pounded into powder) with hide glue made from animal skins. The board is not impregnated with oil as has been incorrectly written in some artist handbooks. Instead, they have little knots and imperfections that give the paintings a natural feel. Many of the water-soluble chemicals and acids that exist in the wood are also leached out leaving an almost inert fiber. This type of plywood is exceptionally dimensionally stable. This is an important physical characteristic because it measures a panels physical integrity and describes how well it is bonded. It is simply wood pulp that is ground up into very fine pieces, and then through a heating process is turned into a partial liquid. There are ways to overcome this and improve lubrication in the first applications on an acrylic priming, by rubbing in a small amount of medium to reduce absorbency. Composite panels such as hardboard and plywood will change at about 1/10th the rate of solid wood. Then add 2 or 3 thin layers of gesso. The Best Surface for Oil Paints: What Should I Paint On? canvas or on panel with or without a ground). would work as well) over the sealant, or you could apply an water-borne ground Regarding sealants, is there a difference between GAC 100 and plain old gloss medium? back round to the original point of the threadI can use the same preparation on a hardboard for oils as i do acrylics. Text pasted in from other sources may contain malformed HTML which the code cleaner will remove. dispersion, etc.). Beyond that, illustration board is one of the easiest substrates to work with. These panels are typically made with thin 3 mm plywood and braced with solid wood strips. paint well before a more traditional linseed oil bound ground but the later Again, over time the thin plywood veneer will open as the artwork is exposed to different levels of humidity. (*Edit: I see this was mentioned in the previous question. acrylic ground and gesso primer are the same thing. So Id use an thinned acrylic ground under any gesso primer layers when using hardboard for oils to prevent the board from rotting or warping. There are a couple of different things going on. Masonite and hardboard are very affordable. The priming process doesn't allow any humidity to access the substrate. http://www.reeves-art.com/guides-and-tips/oil_colour_guide?id=40 I'm a bit confused about tempered hardboard and whether it's considered to be an archival support for oils. is mostly recommended to remove any oil (including hand oils) that may You might need to sand to get a smooth surface, in my case I just dillute with 20% water and create 2 or 3 thin layers without discernible texture by using a soft brush or a roller sponge. With tempered hardboard, a small amount of pH-neutral oil (only 1.8 oz for a 4 ft x 8 ft sheet) is applied with a roll coater at the time the board leaves the press. What is critically important for artists when choosing plywood as an art support is the a) overall thickness of the plywood panel and the face veneers and b) the quality of the veneer. Plywood is built up of sheets of veneer and lumber called plies laid with the grain direction perpendicular to one another and then united under pressure by an adhesive bonding agent. If it is still curled after it has dried for a few days, simply put one more coat on the convex side of the curve. Oil over acrylic The intent of engineered wood products such as plywood and fiberboard is to break up this natural configuration of woods cellular variety and to somewhat homogenize the orientation of the chips or fiber so that these directional shrinkage forces cancel each other out to minimize warping, even out density and surface characteristics and in general, to make a more usefully consistent piece of wood. Modulus Of Rupture (MOR) is a measure of the maximum breaking strength of the board. Let me see if I've got it right. Acrylic primers dont work on paper, imho. But if hardboard can swell from humidity, could it not also soak up oils? Theres also traditional gesso which is great if you are a forger, skip otherwise. as a basic preparation its okay.

In wood products, including all the panels under discussion, moisture is always present in varying amounts expressed as a percentage of the oven-dried weight of the wood. Arguably, the best surface for oil paints to work on is actually copper, large copper sheets. Oh geez, I have just wrote the method for priming hardboards in a thread that is one or two places above this one. Yes, you dont want your hardboard too heavy. Ioli, 2017 . Beyond this, your plans seem reasonable. Thank you to both moderators for your input on this. As to which one to choose, it is a personal choice as both can produce archival quality surfaces if properly used. crushed corner back into something resembling planarity. Most people don't know what masonite is, but this substrate is one of the most affordable, easily sourced materials for painting and many artists prefer this to be the best surface for oil paints. The secret is to choose a bit thats not already warped. I prime with Lowes Rustoleum White gloss (alkyd paint) on wet-media paper, because I paint a lot of mixed-media portraits (acrylic, WMO, and Oils) and require many studies. Gesso is an absorbent material and it will surely allow oil to reach whatever is below it. Subscribe to our newsletter and get instant access to the Pro Level Art Skills Roadmap. Ampersand Art Supply also has a section on their website for sealing and priming unfinished panels. Linear expansion and moisture absorption tests help differentiate the differences among substrates in terms of how effective they are staying dimensionally stable. Hot press is very slick and similar to painting on glass, but cold press illustration board has a bit of a tooth to catch your brush as you work. Itll be fine. A painting on a cotton canvas done by Evolve student Sheila J. In the end, framing can straighten out mild warping, because the warp force is not that strong. Does adding acrylic paint to tint the primer act enough to prime and seal for oil painting? In other words, Bound Water begins to leave the wood under drier conditions and returns under more humid conditions with the wood shrinking and swelling accordingly, a constant change of dimensions. So if you take an old headboard, and cut and sand it down, you will have an incredible substrate to work on. Using a variety of resins mixed with the wood fiber, they are able to achieve quite a dimensionally stable panel. Beyond physical characteristics, the most significant difference between hardboard and fiberboard panels (both MDF and HDF) is the method of manufacturing. You can find them in nearly any hardware or lumber store. Thinner plywood tends to warp and when braced with a solid wood strip, there will be a tendency for any warp in the plywood to force a change in the solid wood strip and vice versa as the panel is exposed to humidity changes. I wish to clarify what the ground step is (as I am already familiar with preparing a hardboard for acrylic painting using this process: sand hardboard with 220 grit sandpaper, apply two coats of tinted mid gray water diluted acrylic gesso up down then side to side and dry with hair dryer.
