How to choose fiberglass?

Density of fiberglass

If there are strong cracks and irregularities, then it is better to putty them, however, do not overdo it, since fiberglass wallpaper has excellent reinforcing properties. This means that they are able to hide small differences in plane and defects very well, while preventing further formation of cracks. At this stage, you can also treat the walls with a fungicidal composition to prevent mold and mildew from growing on them, which is a common occurrence in the kitchen and in the bathrooms.

When starting to cut and glue fiberglass, do not forget about your own safety. Material of even the highest quality can slightly crumble during cutting, and small particles will fly in the air when working with it, the fall of which on the skin and into the respiratory tract is undesirable. Therefore, it is worth wearing clothes that cover the whole body, gloves and cover your mouth and nose.

how to glue fiberglassIt is necessary to cut the glass fiber wallpaper depending on the geometric parameters of the walls in the room, but do not forget to leave an allowance of 5-15 cm, depending on the pattern, so that it can be correctly combined. The roll width, as a rule, is 50 cm, sometimes 1 m. It is convenient to cut it into strips using scissors, you can use a knife.

Now with regard to the gluing itself. It is better to choose a special glue for fiberglass. Some glass wallpaper manufacturers have their own glue in the lines – this is the best option. A composition for gluing vinyl wallpaper may also be suitable, but it is not recommended to use glue for paper wallpaper, since it will not withstand the weight of the embossed canvas.

The finished glue is evenly applied to the wall section with a roller, to which the prepared piece of glass wallpaper is immediately applied. Next, it is worth running over it with a clean roller or a special spatula to ensure better contact with the wall surface, and also so that air and excess glue come out from under the wallpaper.

how to glue fiberglassThe next glass fiber wallpaper is glued according to the same principle. At the same time, the canvases are combined end-to-end so that there are no gaps, but without forgetting about the need for an exact match of the pattern. If excess glue seeps through the joint, then it should be carefully removed immediately with a sponge or clean cloth.

Some defects when gluing glass fiber wallpaper are easy to fix. If in some places they peel off or a bubble has formed, you can draw glue into the syringe and fill the problem areas with it. If the air bubbles are large, you can make a neat cut, and then glue this section of the wallpaper. After painting, it will be difficult to see where the defect was. But if in the process of wallpaper installation, nodules and folds formed, then it will be almost impossible to get rid of them.

How to paint fiberglass?

You can start painting glass fiber only after they are completely dry, which is about two days. But before applying paint, it is better to prime the surface. This is done so that the paint lays down better, and so that it is less absorbed into the porous surface of the fiberglass. Glue diluted with water can be used as a primer. It is applied in a thin uniform layer over the entire surface of the wallpaper, and after it dries, they proceed directly to painting.

glass wallpaper paintingIt is very easy to paint fiberglass, and a beginner can handle it. It is better to use a roller for this. It remains only to choose the required paint color, and maybe several colors, if it meets the interior concept.

  • water-dispersion paint, resistant to washing. Matte formulations or silky matte are optimal;
  • acrylic paint;

  • latex paints;
  • polyurethane varnish-paints are also quite applicable.

Depending on the desired effect, the paint is applied in one or more layers, but you need to wait until the previous layer dries. It is better for beginners in painting to choose matte compositions: if there are any irregularities on the surface, they will be hardly noticeable.
