Certain types are more appropriate for external applications, while others are perfect for interior use. Selecting the appropriate one can help you save time and effort while producing a more polished outcome.

We’ll look at some of the top plaster mixtures for Penoplex in this post. We will also guide you through the essential phases of the plastering procedure, enabling you to attain a flawless and long-lasting wall finish.

The pros and cons of the facade insulation foam

The primary benefits of the content are:

• low thermal conductivity (coeff. thermal conductivity 0.03 W/m · ºK)
• resistance to compression and the ability to withstand mechanical loads, due to the homogeneous structure of the material, where evenly placed pores, increasing the strength of the heat insulator;
• low water absorption (0.2 – 0.4 % of the volume in 24 hours with full immersion);
• It withstands a wide range of temperatures: from-50 to +75 degrees;
• resistance to mold and decay;
• resistance to fire;
• good soundproofing qualities;
• small weight of the material – simple transportation;
• Simplicity of installation, installation of plates is possible on its own by one person. The standard dimensions of the foam: width 600 mm, length is 1200 mm, thickness from 20 to 100 mm;
• versatility, the ability to insulate any elements of the building: walls, basement, foundation, roof, floor;
• safe, does not emit toxic substances;
• long service life, subject to proper use, at least 50 years.

Among the material’s drawbacks are:

• low vapor permeability (0.007-0.008 mg/m h Pa). When using the material indoors, good ventilation must be ensured to avoid condensation and mold. It is also impossible to insulate aerated concrete without internal vapor barrier of the walls.
• high price – more expensive than foam plastic and mines.cotton wool about twice.

Penoplex has become widely used and is replacing traditional polystyrene foam in building insulation due to its heat-saving properties and simplicity of installation.

Is it possible to plaster it??

Penoplex is resistant to moisture, but it still needs to be shielded from precipitation. Furthermore, this is required to give the building a pleasing appearance. MDF and PVC panels work well for completing this insulation inside. You can arrange wall panels or siding to create a ventilated facade outside the house.

Penoplex plastering can be done both indoors and outdoors. This will be a commonplace way to finish. We’ll examine how to accomplish this as well as the prerequisites for the task below.

Selecting the proper mixture is essential for a long-lasting and efficient plaster finish when using Penoplex. This post examines the top plaster choices for Penoplex, emphasizing the advantages and methods of application. It describes how Penoplex interacts with different plaster types to ensure adhesion and long-lasting protection. Making the appropriate decision will result in a smooth, long-lasting surface that improves insulation and withstands wear and tear over time.

Which mixture is better?

It is important to consider the climate and features of the plaster you choose. Because plaster needs to ensure fire safety, smooth out base irregularities, improve heat and sound insulation qualities, and shield insulation from mechanical, chemical, and environmental factors, it also needs to give the room an immaculate appearance.

Plaster mixtures come in the following varieties:

• Mineral. A mixture based on cement, sand, as well as plasticizers and adhesive additives. It is a good choice for use as a base coat for painting or decorative plaster. The solution is easy to apply, resistant to fire, moisture and mold. At the same time, it is inexpensive.
• Acrylic. Presented in the form of a solution based on acrylic resins with mineral additives and dyes. Main advantages: a rich range of colors and textures, elasticity, durability, resistance to precipitation and ultraviolet radiation. Creates a dense, waterproof film.
• Silicone. Characterized by high elasticity and durability. A universal mixture with high performance qualities, has a rich palette of colors and is offered in the form of a ready-made solution. Disadvantage – high cost of the material.
• Silicate The mixture is made on the basis of liquid glass, protects well from frost, wind, humidity and temperature changes. The composition has good vapor permeability, therefore it maintains a comfortable climate in the room. Requires efficiency in work, because it sets quickly.
• Silicate-silicone the plaster contains a water-repellent additive, mineral fillers and coloring pigments. Technical characteristics include increased mechanical resistance and elasticity, resistance to precipitation and good adhesion to the surface.

Let’s review the superior plasters. Plaster with a cement-sand base is appropriate for providing additional thermal insulation to the building as well as protection against mechanical damage. However, the plastered surface won’t look good. As a result, it will be essential to paint the facade again or add decorative plaster.

Silicone is going to be the most costly but also the most resilient of the aforementioned compositions. The customer’s opinion will be the only one that counts when selecting texture and color, determining whether "bark beetle," "fur coat," imitation stone, or another finish is more similar to him.

How to plaster outside and inside a room: step-by-step instructions

Plastering is not a very difficult process; however, it needs to be done according to technology.

To do your work, you’ll need tools.

Required supplies:

Preparing the base

1. Fill the seams between the slabs with polyurethane foam;
2. After hardening, cut off excess foam with a knife and rub with a float;
3. Deepen the dowel heads. If you can’t drive them in, you need to cut off the head and hammer in another dowel next to it, having made a hole for it in advance;
4. After finishing the work, treat the walls with a deep penetration primer.

Reinforcement with mesh

1. Seal the dowel heads and the recesses on the insulation.
2. Attach aluminum perforated corners to the outer corners.
3. Cut out the fiberglass mesh, taking into account that the fabric will be mounted overlapping each other.
4. Coat the base with an adhesive composition 3-5 mm thick and apply the mesh. Align it with a wide spatula, pressing it into the plaster.
5. Apply another layer of adhesive over the reinforcement.
6. Rub the dried reinforcement layer with a float in a circular motion, without excessive zeal and with equal pressure.

Plastering penoplex

1. After reinforcement, you can begin to plaster the walls of the room. Apply the mixture with a small spatula to a large construction spatula, apply it to the wall and level it. The layer thickness should be 3-5 mm.
2. After drying, you need to sand it again until you get a smooth surface.
3. To get rid of increased dampness and mold, apply two layers of primer at intervals of 3-4 hours, using a roller with a short pile.
4. After the primer dries, apply decorative plaster with a wide spatula. To create texture on the wall, use relief rollers and stamps. The choice of tool depends on the type of mixture. For example, pebble plaster is simply leveled with a trowel. A “fur coat” on the wall is created with a roller.
5. If the tinting of the solution was not done before applying it to the wall, then it is painted after drying.
6. When plastering indoors with a mixture on a gypsum basis, the wall can be additionally treated with special varnish.

It is recommended that facade plaster be applied during periods of favorable weather.

• Air humidity-65-70%;
• Poultry temperature indicators in the range from 5 to 25 degrees above zero;
• Lack of strong winds.

For Penoplex, selecting the appropriate plaster is essential to achieving a long-lasting and efficient finish. Selecting a mixture that adheres well and offers the required protection is crucial because not all mixtures are appropriate for this material.

Plasters based on cement and polymers are the most compatible with Penoplex among the options available. They are perfect for applications both inside and outside because of their strong adhesion, flexibility, and moisture resistance.

It is just as crucial to use the proper technique and material selection when applying plaster to Penoplex. To get a smooth and durable finish, proper surface preparation—including priming—and the use of a reinforcement mesh are essential.

Your Penoplex insulation will continue to be protective and effective for many years if you apply the plaster correctly and choose the right plaster.
