It is possible Whether to putty penoplex and how to do it. A material such as penoplex has a huge number of advantages compared to other types of insulation, and therefore it is no secret to anyone that most owners of private houses are trying to use this particular material for ennobling their own homes. However, not everyone knows that the process of filling such a material for thermal insulation has certain nuances.
For this reason, in the article below, you will learn how to putty penoplex indoors and outdoors, as well as the technology of work that will make it possible to create a reliable, high-quality and durable rough coating.
It should be noted right away that penoplex will be more correctly called extruded polystyrene foam, since the familiar word "penoplex" is the real name of the company, which is engaged in the manufacture and sale of this thermal insulation material.
To a certain extent, this resembles the situation with copying machines, which in the CIS countries are still called nothing but a "copier".
Extruded polystyrene foam is based on the simplest polystyrene foam, namely foam.
But thanks to the processing of the material using a special thermal method, the material was able to obtain the following extremely valuable qualities:
In addition, a material such as penoplex has a low level of adhesion when compared to foam. Because of this, it will be a gross mistake to spat such material using standard technology. This can lead to the fact that the putty will begin to lag behind the layer of insulation and reinforcing mesh. Although penoplex is not designed to be wet-faced, plastering is actually possible.
Construction specialists have been able to develop a technology for finishing, which makes it possible to obtain high-quality results, as well as guarantees a high level of strength.
The process of facing the "Penoplex" heat-insulating material consists of the following stages:
Each of the stages is extremely important, so you should treat all of them responsibly.
Preparation of material and surface for finishing work
First, you should figure out what kind of plaster will be used to finish the foam.Experts advise using universal mixtures from popular brands for work. But it is worth noting that there are also special compositions that are designed for plates made of expanded polystyrene. One of these products in order to be able to putty penoplex is a plaster-adhesive mixture from the manufacturer Cerisit.
The composition should be prepared exactly according to the instructions that are indicated on the package, but there is a particularly important point that is related precisely to the consistency of the solution.
To install a reinforcing stack, the consistency of the composition must necessarily be slightly lower than the manufacturer recommended.
Please note, that for leveling the solution must be as liquid as possible. In order to install the reinforcing mesh on the surface of the extruded polystyrene foam, you need 4 kg of the compound per square meter, and all 6 kg of the compound are required to create a layer to level the surface.
In order for you to be able to qualitatively plaster the penoplex, you will need to prepare in advance the following materials and tools:
In addition, grouting of the penoplex will be included in the preparatory stage in order to eliminate possible irregularities and surface drops. You should not rush to complete the work, since the overall result at the end will directly depend on the preparation.
Installation work for the plaster mesh is a very important step, and without it, the plastered walls can begin to crack, and this is will significantly affect the service life. To install a reinforced mesh, you will need to apply a layer of adhesive on the surface of the foam, and its thickness should be 0.3 cm and glue it all to the product.
In addition, when performing such work, you will need to take into account the following nuances:
Most often this is done in strips that are no more than 1 meter wide, since this is exactly the width of the front walls.
3 meters, bend in half, and then press down to the corner and press into the adhesive.
After the reinforcing layer has dried, it will be necessary to trowel the surface. For this task, we recommend using a grinder or grater, which is equipped with an emery cloth. Mashing should be done in a circular motion and done counterclockwise, but do not apply too much pressure on the working tool.
Please note, how to properly putty penoplex - it should be noted that the drying time of the solution will directly depend on weather conditions.
In hot weather, you will need to wait only a few hours, and after that you can grout, but in cold weather it is better to wait at least a day.
Finishing coat (putty)
And the next, no less important and the very last procedure is leveling the surface when using plaster. To do this, use the previously unpacked universal compound, as for surface reinforcement. The mortar should be applied with a trowel and spread evenly over the entire wall surface. Please note that the layer thickness should not be more than 0.
The final procedure is mashing the foam. Everything is carried out in the same way as with reinforcement, and only after the solution is completely dry. To dry completely, you will need to wait at least 24 hours, and even more in the cold season. But it is also better not to wait for a long time, because after 4 days have passed, the solution can harden strongly and grouting simply will not work.
After you have completely processed the entire surface, the plastering process can be considered completed and we suggest moving on to puttying the premises.
Putty is a finishing surface finish when using special mixtures for puttying. The choice of the composition will depend directly on the surface to which it will be applied. There are compositions in the form of a powder, and there are in the form of a paste. The latter type is acrylic, silicone, oil and combination type.
Interestingly, that for penoplex the best option is a composition based on acrylic, or powder type. Even silicone varieties can be used for interior lining.
Also, when choosing a putty, you should take into account the binding components in the composition and how high-quality the substances are. The durability of the solution, as well as its protection from moisture, cold and various types of precipitation, will directly depend on the quality of the binding components. When choosing a putty for penoplex, it is better to additionally consult with sales consultants.
They will help you make the right choice that can withstand the required loads.In addition, you should take into account that facing mixtures for rooms from the inside are not suitable for finishing the facade, so it is better not to save money, as otherwise you will need to redo all the work again.
If you decide and use a dry putty, then first you need to dilute it. To do this, fill a bucket with clean water, and then start gradually adding the powder, and the composition should be stirred with a construction mixer. The putty must necessarily resemble mashed potatoes in consistency.
After you get the perfect solution, you should leave it for 5 minutes, and then stir it again, and only after that you can begin to putty the surfaces.
Please note that before puttingty penoplex, experts recommend treating the surface with a special primer mixture that can provide adhesion and a high level of waterproofing.
How to properly puttying such heat-insulating material as penoplex? To apply the ready-made solution, you will definitely need a wide spatula, but you will spread the mixture on it with a narrow spatula. When creating a finishing cladding, it is extremely important that the treated new surface area in appearance and level merges with the previously putty. The joints should be practically invisible, so it is better to seek help from the masters of their craft.
They know exactly how to putty thermal insulation penoplex correctly and quickly.
The maximum permissible thickness of the putty layer when applied is 0.5 cm, and after it has hardened, the entire coating should be trowelled. It should be done in a circular, precise motion using an abrasive mesh. It should also be taken into account that grinding is allowed to be carried out no earlier than 5 hours after the composition was applied.
Good advice! When the grout is complete, you will need to reapply the primer coat to help remove the accumulated dust layer from the surface and make the entire finish smooth, perfectly even. After the primer is dry, you can start painting or other type of decorative cladding.
As you can see from all of the above, insulation with foam is a great option. Such a material is allowed without problems and plaster and putty, and this will provide an additional level of protection, as well as an excellent appearance. The main thing is that you are responsible for the choice of the mixture for processing, and also apply it correctly, because the final result of the work will directly depend on this.
If any complications appear, you should immediately seek help from specialists.
