Information and tips about stretcher bars

Acrylic images can be used with a variety of image carriers. Acrylic paints adhere and shine on nearly all surfaces, on canvas or wood, as well as on metal, plastic, stone or paper.

However, the painting technique used can influence the selection of the image carrier and, in principle, the stain should be the more stable the thicker the color layers are.

For a large part of the acrylic paintings, however, are used quite classic and inspired by the oil painting, covered with canvas or cotton stretcher. But stretcher frames are not the same as stretcher frames, and there are also some points to consider when stringing and priming.

A stretcher is a simple wooden construction that usually uses softwoods such as spruce, fir or pine. The frame rails are cut so that they can be pushed together at an angle of 90 degrees. The corner joints are usually not separately fixed, so that the stability is created only by the stringing with the canvas.

· When buying frame strips, make sure that they are as straight as possible.

· Better than simple frame strips are glued frame strips. These are wooden ladders, which consist of several smaller, glued together wooden strips. The advantage of these strips is that they are less prone to warping.

· When selecting wood strips, the smell should always be taken into account. Woods with a strong woody odor point to freshly cut wood and there is also the danger that the wood will warp over time.

· When assembling, the frame rails should be joined together as closely as possible. Otherwise, there is a risk that the frame later is not exactly right-angled.

· If a hammer or other auxiliary tool is used for assembly, a piece of wood should be underlaid. Otherwise, dents may appear that are later visible in the picture.
