Wax application for decorative plaster Do I need to coat decorative plaster with wax

Decorative plaster has become a fairly popular material for decoration, which widely used for wall cladding in apartments and houses.

It is suitable for indoor and outdoor use, very easy to clean, and also looks quite impressive.

In order for this type of coating to retain its attractiveness as long as possible, you need to cover the decorative plaster with wax - such a protective composition on an environmentally friendly base.

General information

Features and purpose

Wax for wall treatment is used together in different types of plasters - with standard finishing, or Venetian like "bark beetle" and "fleece". The main purpose of the application is to create a water-repellent coating on plaster, which itself tends to absorb moisture.

In addition to enhancing the moisture resistance of the finishing layer, the product will perform the following functions:

With the help of wax, you can create unusual tonal transitions on the surface of the walls, make a drawing, change the finishing texture.

The compositions will be made on the basis of acrylic-type copolymers, natural varieties of wax, various modifiers and fillers. Due to the absence of harmful components, they can be used in all rooms, even in children's rooms. In addition, the products are vapor-permeable and will not disrupt the natural exchange of air in the home, and therefore you will maintain a healthy microclimate.

Types of compositions

Wax for plastered surfaces is of synthetic and natural origin. Here we are talking about the base - in natural components, palm or beeswax will play its role, which gives the finish an unusual shine.

Such compositions are hypoallergenic, but have a shorter service life than artificial ones. The latter are made industrially from non-hazardous components. Synthetic products are almost immune to moisture, temperature extremes, wear resistance and do not require frequent layer renewal.

Depending on the structure, all products can be divided into the following types:

  • Liquid - they are easy to apply with a brush, they quickly fill even the smallest pores of the base, ideal for highly porous and rough surfaces.
  • Thick - more suitable for smooth materials, for example, for plaster with imitation of granite and marble.

Venetian-style plaster waxes can be chosen from a wide range of colors. The main varieties are:

  1. Transparent - they provide a shine, an unusual gloss, or a soft silky effect.Usually applied on plaster with already produced complex staining or stone imitation.
  2. Colored - helps to change the tone of the substrate or to color clear coatings. Products from different manufacturers are produced in excellent color variations.

  3. With decorative additives - the most popular will be waxes with silver or gold dust. They are used to imitate silvering, gilding, and also to give the coating an unusual metallic sheen.

Now a little about how to choose a tool for different surfaces.

The choice of wax for various types of surfaces

When purchasing a wax (to get a waxed plaster), you should pay attention to the compliance of the composition with a certain type of plaster in terms of operation characteristics ..

. For example, the Venetian should be applied not in one, but in several layers to provide it with a special look of antique or stone. Wax should only emphasize the beauty of the walls, but not drown it in any way, and because in this case, you should choose transparent compositions with a moderate sheen. Plain and dull coatings with a matte texture can be decorated with bronze dust wax or even sprayed on. Similar effects work well with Moroccan plaster.

There are formulations that are specifically designed for vintage-style decoration - they give the appearance of a cracked wall, and wax works much like craquelure varnish. When choosing a wax for a kitchen, bathroom, sanitary unit, attention should be paid to moisture resistance - this indicator should be the maximum.

Price and quality

The cost of the product will strongly depend on the manufacturer and the components that are included in the composition. It can range from 450 to 5600 rubles per 1 liter. For example, the material for waxing from the Russian brand "VGT" costs 460 rubles per 1 liter, and the Swedish wax Parade Ice Vеnezia Wax costs about 1200 rubles per 1 liter, and Cera di Vеnеzianо as much as 5500 rubles per 1 liter! You shouldn't buy the cheapest waxes because they may be of poor quality and won't last long.

Normally, it is worth renewing the coating every 4-5 years, and low-quality formulations may lose their attractiveness and protective properties even after a year. Even when buying, you should pay attention to environmental friendliness and the absence of allergenic components in the composition.

Waxing - step by step

Wax application for decorative plaster Before starting work with the product, prepare the surfaces with the plaster applied to it as best as possible (the latter must be 100% dry). Remove dust from the base, preferably with a vacuum cleaner. The plaster should be free of pits, the rest of the defects - after applying the wax layer, they cannot be corrected.

Please note that liquid formulations can be applied even with a soft flannel rag, cloth napkin, and for thick ones, you should buy a rubber spatula.You should immediately buy the required amount of the base material - the consumption is 0.075 kg per square meter (in one layer).

But very dense waxes can be diluted with water, warming it up in advance by the battery or even in a water bath. It is important that the volume of water does not exceed 3% of the total mass.

The composition will lay down softer and more pliant on the primed layer of plaster, while priming should be carried out with wax (for 1 measure of wax, add 4 measures of water). Let the primer dry well.

Application and polishing

The wax should be applied in such a way that its layer rises slightly above the surface and fills all the pits and depressions in plaster. This should be done in continuous mode - in this case, all areas will seem evenly painted over. A beginner should call on an assistant to wax a large area.

It is better to apply the product from the corner and move along the wall. After application, the composition should be rubbed with a slightly damp sponge on the base, and then rubbed with a soft cloth until a shine appears. Any excess product that has not managed to be absorbed should be wiped off immediately. If the method involves toning cracks with dark wax, for example, do not touch the composition filling them, then the relief will turn out to be more distinct. To enhance the shine, you need to polish the walls with a grinder with a special attachment.

The drying time of the wax is up to 14 hours, and complete drying will be after a week.

How to correct errors

Covering decorative plaster with wax is not difficult, but sometimes it turns out that the composition was applied unevenly, and noticeable spots and stripes appeared on the surface. It is advisable to correct errors immediately, while the material has not yet grasped. It will be enough to moisten a rag with water, and then remove the excess or add a little wax, then polish the surface. Sometimes mistakes are noticed later, after 6 hours, when the wax has partially hardened.

In this case, you need to warm up the area with a defect with a hair dryer, wet a rag with hot water and rub the walls. Use a solvent to remove caked and tough build-up. If wax has accumulated in the inner wall corners, it is allowed to wrap the trowel with a white cloth and re-sand the areas.

How to remove the wax layer

A very thick wax layer that has not had time to harden can be washed off with hot water using a soft, unnecessary cloth. Difficult areas can be wiped down with white spirit or another type of solvent.

Dried wax is removed by grinding with a thin and fine-grained sandpaper using a grinder or sponge. Then remove dust and wax residues with a vacuum cleaner.

Recipe for creating wax with your own hands

Quality products are very expensive, and it is not always possible to use them to decorate the entire room. In this case, there is an option to independently make compositions for the final treatment of the plastered wall.

Wax based on soap

This product is prepared from simple toilet soap.

A piece of 0. 15 kg should be rubbed on a coarse grater, and then pour boiling water (7 liters), bring until completely dissolved. Separately, 2 teaspoons of soda are diluted in a small amount of water, and then added to the solution. The product should be whipped with a whisk, left to cool, and then the wax will be ready for application.

Composition based on natural wax

The following components should be prepared:

  • 2 measures of beeswax (it can be replaced with paraffin).

  • 1 measure of refined turpentine.
  • 1 measure of linseed oil.
  • Any pigments (if needed).

The wax should be cut and then melted in a water bath. Add all the other components and use a whisk to homogenize the mass, and then let it cool and use the product as directed.

Means based on glue for wallpaper

Dilute the usual adhesive in advance according to the instructions, and then leave to infuse for 1/2 hour. Next, we filter so that there are no lumps. In 2 measures of adhesive, add 1 measure of acrylic-based varnish and 1/2 measure of any paint (decorative). Next, mix the composition as best as possible and apply it to the plaster, like ordinary wax. If you plan to make the finish colorless, then you do not need to add paint.

How to replace wax

It is extremely important to coat decorative plaster with wax, especially in rooms with high humidity. She will not receive adequate protection and will not be able to create a beautiful appearance. If the application of the compositions is impossible for any reason, then it can be replaced with varnish.

The latter will perform similar functions:

  • Keep the beauty of the finish and the brightness of colors for a long time.
  • Protects against negative factors.

  • Protects from getting wet.
  • Provides beautiful shine.

As a rule, water-based acrylic varnishes are usually used for plaster treatment, because they are environmentally friendly and suitable for interior work.

Please note that the composition must be moisture-resistant and vapor-permeable, otherwise it will not last long and will disturb the microclimate in the house. Most varnish compositions dry in 3 hours, and they can be not just glossy, but also matte, and are also sold in different colors, with a metallic sheen or other visual effects.


According to experts, the benefits of wax are difficult to overestimate. After waxing, the surface of the walls looks exquisite and expensive. With the right choice of colors, the room will be more beautiful and stylish. In the reviews, users note that after application, the walls do not deteriorate from the ingress of water or a constant high level of humidity. The hostesses admitted that they like the ease of care of such surfaces - they can be washed with an ordinary rag.

When choosing decorative plaster for finishing a house, you should immediately think about its protection and apply a topcoat. It is ideal if it is wax - the material is beautiful, reliable and serves for many years!
