The Classic canvases are eraser-proof. Under the following conditions, you can remove sketches without leaving any residue.
After the colors have dried, the artwork can be treated with a fixative if necessary. For this purpose, you should use the conservation measures appropriate to the technique.
For hanging is best suited a dry room. Bathroom and kitchen are therefore not optimal. For better color protection, you should ideally choose a location with little direct sunlight. Then you can enjoy your artwork for a long time.
For presentation, you can hang the canvases directly on the wooden bars. Framing is not absolutely necessary.
In the following examples of canvas hanging, we will mainly deal with the attachment to the stretcher frame itself. All the examples mentioned are basically possible with canvases from MHP. The requirements mainly concern the size and weight of the painted canvases.
To hang a canvas without drilling, you can use special adhesive hooks. The hooks, usually a triangle, here are attached to an adhesive surface. The hook protruding from the top of the frame can be hung on a small nail, or on nylon threads, wire, etc.
However, this works only up to a certain weight. Depending on the design of the self-adhesive picture hangers, a painted stretcher frame can weigh 800g up to 1.5kg.
If you also wanted to spare the wall from holes, you can go for complete adhesive variants here as well. The special adhesive strips directly connect the wall and the stretcher frame. The canvas can be glued on all sides. With a good substrate könenn so even roof slopes can be decorated with painted canvases.
The adhesive strips also hold only up to a certain weight. Depending on the producer up to 5 kg per m². It should also be remembered that the surfaces to be glued must be smooth. It should also be noted that some adhesive substances leave a greasy film. So if you remove the glued picture frames after a long time, it may be that oily traces remain on your wallpaper. So inform yourself carefully about the respective product.
Another temporary hanging device is sheet metal hooks, which are simply clamped into the top frame bar. This device holds by the weight of the frame itself and does not require any screws or nails. These hooks can then also be hung from string, wire or a wall nail. When the picture is hanging, it can also be balanced simply by sliding the picture hooks back and forth. If you have a canvas with an MDF frame instead of a real wooden stretcher frame, it is especially recommended that you attach it with sheet metal hooks, since MDF is not as sturdy as wood and is not very suitable for screwing, and the surface is usually too porous for gluing.
Here it depends on what profile your painted canvas has. These hangers are particularly suitable for profile strips with a thickness of up to 20mm. The material of the framing does not matter here - MDF works just as well as wood. The paintings can have much more weight with tin hook hangers than with glue hangers.
In general, if you drive screws or nails into the stretcher bars outside of the mating connection in the corners, you can still re-stretch the canvas years later in case of necessity.
Picture hangers and hanging hooks
The most common method of hanging stretcher frames are picture hangers and hanging hooks. These come in many shapes, colors and names. Serrated picture hangers, sawtooth picture hangers, picture hooks would be some common terms.
Here the metal hangers are attached to the top or side frame rail with nails or screws. Here, too, there are special hooking systems that allow you to attach stretcher frames to roof slopes. In this variant, it is recommended to additionally attach one or two picture hangers to the lower picture rail.
In this diverse method, almost anything is possible, and most wooden stretcher frames can be hung with picture hangers. The important thing here is that the nails and screws you choose match the hanging and your frame. If the frame rails are thin, the screws and nails should also be small.
Screws and wire or string
This option of picture hanging is mainly suitable for hobbyists. Here, two wood screws or eyebolts are driven either into the side moldings and loosely connected with a wire or string. The painting is hung on this connected string. Since the wire or string hangs loosely on a wall hook, the stretcher can also be readjusted. The special thing here: the canvas hangs tilted downwards. In this way, you can avoid dusting of the painted surface and achieve a better viewing angle for pictures that are mounted particularly high. The angle of inclination depends strongly on the position of the screws and the tension of the cord. The following applies: the lower the position of the screws and the looser the connection, the more inclined the canvas.
This option is primarily an option for sturdy stretcher frames that can tolerate heavy-duty screwing. Important, if you have a particularly heavy frame and therefore want to use thicker screws, be sure to pre-drill the hole so that the wood does not spread at this point. The width of the frame should not exceed 60 to 70 cm, because the tension in the wire or cord would be too high.
Heavy duty hanger
These stretcher hangers are flat angles or rails with screw holes for particularly large and heavy canvas paintings. Depending on the system, frame weights of over 30 kg are possible with heavy-duty hangers.
For large and heavy paintings, it is recommended to use a frame thickness of 4cm. In this way, the suspensions can also be made with robust screws. Again, when using thick screws should be absolutely pre-drilled to avoid splintering of the bars.
