Thanks to the varnishing process, the performance and beauty of the plaster can be greatly improved. Everyone will decide for himself what kind of varnish should be used to cover decorative gypsum stones, since each product has its own shine, shade, color and other characteristics.
Here is a list of the main recommendations and rules that should be followed when varnishing to obtain the best result:
- Before applying the varnish composition , plaster figures and other elements should be well dried. If you use enamel, glue, paint or other coatings, they must be completely dry.
- Any plaster objects, including figurines, figurines, and others, should be kept at a temperature of about +20 degrees for 24 hours. If this is not done, then the varnish coating can quickly lose its performance characteristics.
- If you plan to varnish rough products, first you should sand them, for example, with sandpaper.
The sanding process is desirable before the tile is glued to the wall surface, otherwise sanding can be difficult.
- If impregnations are additionally applied, you should carefully read the instructions that come with a particular product. Certain types of impregnations are applied before varnishing, and the rest after varnish. There are also those impregnations that simply cannot be combined with the varnishing process.
The use of lacquer glitters will reduce the natural effect, but make the products more festive.
If the room is decorated in natural and natural colors, styles, then it is advisable to buy matte varnishing solutions.
The preparatory stage is quite simple - all kinds of dirt and dust should be removed from the products. When cleaning, do not moisten the surface, as this material quickly absorbs moisture. At the end of cleansing, impregnation should be applied, for example, to increase moisture resistance or impart antiseptic properties to the material. The impregnation should dry out perfectly, and then it is allowed to varnish.
The choice of tools should be based on the method used to apply the plaster tile varnish. For varnishing, you can use a roller, brush, foam rubber, as well as a small-sized spray gun. It should be applied to small-sized figures and hard-to-reach places, then a small-sized brush can be used. For sanding the surface after applying varnish to the plaster, you should prepare a machine for sanding, or the simplest sandpaper.
After sanding, you will need a vacuum cleaner to remove dust and dirt.
In addition, prepare:
Simple brushes made of natural materials, as well as fleecy rollers for varnishing plaster products, will not work. When using them, the consumption of the composition will be very large, in addition, many drips will appear on the base.
It is difficult to work with a brush, and when applied, streaks and smudges appear, even with experienced craftsmen. But you definitely can't do without a brush if you want to cover uneven and even torn parts of the cladding.
The best method, compared to a brush or roller, is to use a spray method. The spray gun or airbrush makes it possible to varnish everything with an even layer, the plaster base will become monochromatic. Only at the expense of a spray gun can you make smooth transitions from light to dark parts.
Moreover, holding the airbrush at different distances from the surface can achieve different varnishing effects. There is no need to use an expensive spray gun, even an inexpensive device does an excellent job of varnishing surfaces, but its compressor should be of fairly high quality.
