Decoupage is the decoration of objects with paper material by gluing and then fixing. It is applied on various surfaces: wooden, plastic, metal, glass, paper, and also having a different form. It can be either flat objects, such as a board, countertop, stool, cabinet front or box, or voluminous.
Particularly popular are flower pots, bottles, carafes and glasses. Decoupage of volumetric products is more difficult, it requires not only an understanding of the process in theory, but also the experience of repeatedly applying it in practice. The main problems with this technique are the fragility of materials, the formation of bubbles and wrinkles and poor adhesion to the surface. To avoid this, you must strictly follow each step of the glass decoupage master class.
So, before you get started, you must first prepare everything you need. To turn a simple item into a work of art, you will need:
- Glass. UseYou can use any wine glass, regardless of its shape and color of glass. The main thing is that it be smooth.
- Paper. These can be special sheets for decoupage on a paper or rice basis. The latter variety is quite expensive, but durable and stretches well, which makes it easier to stick it on surfaces of complex geometric shapes than other types. However, the most common material is paper three-layer napkins with a pattern. This is a fairly easily accessible and budget material with a large selection of patterns. The only negative is that such paper is very fragile, the workpiece can be deformed from excess water or incorrect brush movement. You can also use newspaper clippings, matte photos printed on office paper. However, such materials are quite thick, so it is difficult to use them for decoupage of glasses.
- Glue. It is better to use a professional composition, it has an optimal consistency, does not contain excess moisture that violates the integrity of the paper, becomes completely transparent when dried, does not change color over time, does not have a strong smell, dries quickly enough, but not so much that it is not possible to correct the location element during operation. However, its cost is higher than that of simple stationery glue, so PVA is most often used, slightly diluted with water.
- Lacquer. To fix the product, it is necessary to cover it with acrylic varnish. Aerosols are best.
- Primer. It is necessary for better adhesion of paper to glass. Instead, you can also use varnish applied in 1layer. You can stick the picture only after complete drying.
- Acrylic paints. They can correct the application, decorate the edges or paint over the joints if the overall picture consists of several small details.
In addition to the materials listed above, for decoupage of glass goblets you will need:
- Brushes: flat, with artificial bristles - for applying glue, thin round - for painting, thick round - for joints.
- Foam sponges. Handy for applying primer, varnish, final leveling of paper and cleaning up excess water.
- Scissors. It is convenient to use manicure or medical instruments.
- Multifora (file).
After all the materials and tools are prepared, you can get to work.
First, the base must be degreased with an alcohol-containing liquid, and then proceed to priming.
There are 4 types of glass design:
- Solid. It implies covering the entire surface of the product with an image. In this case, first it is completely covered with a primer or varnish. Then it is painted white or to match the background of the napkin.
- Partial on general. The entire area is primed, everything is painted, except for the pattern area with a margin. This is done so that the entire surface of the finished product has the same number of layers of paint. In this case, the background shade will be the same everywhere. Otherwise, in the area of the picture, you will get an overlay of layers andthe color will be more saturated.
- Partial on selective background. In this case, not the entire glass is primed and painted, but the part that is provided for in the sketch. Fragments of the product remain transparent.
- Partial on a transparent background. Here, only the place where the drawing will be located is primed and painted with white.
Paper work begins. The selected images must be separated from the base. They can be cut out - the method is suitable for large drawings or when decorating on a transparent background, or cut off by hand. In this case, it is easier to combine the pieces into a single composition. The technique is suitable for compound drawings, solid coverage or partial on the general background.
When working with napkins, only the top layer is used, while the bottom two can be used as a background or for training.
The most important part is the decoupage of the glass itself. There are 3 ways to process wine glasses:
- A drawing is applied to a dry surface, after which glue is applied over it with a flat brush in small portions. Movement - from the center to the edges in a circle. In this method, it is important to remember that when wet, the paper stretches, respectively, its size will increase. This method is convenient because in this case almost no bubbles form, but it is necessary to clearly control the amount of glue and the force of pressing the brush.
- The surface is treated with glue. Paper, patterned down on a piece of multifora (file),sprayed with water, then applied to the glass over the glue. To make it more convenient, the image is not detached from the substrate immediately. It must be bent in an arc, leaned against the product, and then gradually applied from the center to the edges, smoothing through the file.
- A dry pattern is applied to the wet surface, only its center is fixed. Next, it must be wetted with a brush, spreading over the product. Since the center will stretch, wrinkles will form, which can be removed by lifting the paper by the dry edges. After the pattern is located on the surface, carefully apply glue on top.
When all the elements are attached, it is necessary to dry the product. This will take 10-12 hours at room temperature.
The next step in decoupage glasses is to eliminate imperfections. First, you need to lightly walk along the contour of the pattern with fine sandpaper to remove the protruding parts. In the same way, you can get rid of a small crease.
After that, start decorating. Mask the joints between the elements and paper with the background with acrylic paints. It must be remembered that it darkens when it dries. In addition, you can outline the outline of the picture, for example, if it is made in the form of a medallion or you want to highlight it more. After all the strokes are finished, it is necessary to let the product dry again.
And the final stage - varnishing. You have to be very careful not todeform the product, since both paint and paper are still easy to spoil. Lacquer must be applied in 2-3 layers with an interval of 2 hours. This completes the decoupage of glasses.
As with any other needlework technique, there are some tricks here. To successfully complete the work, you must consider the following nuances:
- It is better to iron the napkins before use to remove unnecessary creases.
- If you wet and dry the paper before processing, it will not change its size again when wet. At the same time, it will become less comfortable for working on surfaces of complex shape (for example, the side of a cognac glass).
- Before gluing, the paper can be varnished, partially dried, and then attached to the product. In this case, the risk of tearing the design when smoothing on the surface is reduced.
- Stained glass goblets can also be decorated using the partial coating technique. Moreover, you can use not only paper, but also decorative foil or gold leaf.
- If the decoration of the glass is required for only one event, it is enough to cover the product with only 1 layer of varnish, and after the celebration, remove the decoration with a solvent.
- In glasses with a high stem, you can decorate not the side surface, but the base itself. In this case, varnish is used instead of a primer, and the paper is glued to the glass with a pattern.
- A hair dryer should not be used for drying, this leads to deformation of the paper and the appearance of cracks. Suchthe same result will be obtained if the paper or paint is not completely dry.
- The glasses must be allowed to stand for about two weeks before they can be used.
Do-it-yourself tableware will be a wonderful gift for a wedding, anniversary or New Year's celebration. Decoupage of glasses, despite the many nuances, is a little more complicated than decorating other surfaces. However, it is this item that is often used on holidays and will remind you of the donor for many years to come.
