Plaster of stoves and fireplaces from A to Z

Few things compare to the warmth and allure of a stove or fireplace when it comes to warm-heartedly furnishing your house in the winter. These vintage heating fixtures give a sense of ambience to any space in addition to comfort. However, appropriate plastering is necessary to guarantee their effectiveness and durability. Plastering is essential to maximizing the performance of fireplaces and stoves, from improving insulation to sealing cracks.

Plastering may seem like a difficult undertaking, particularly to individuals who are not familiar with construction jargon. But do not worry! This guide is your all-inclusive road map, covering every aspect of plastering fireplaces and stoves from beginning to end. Be it an experienced do-it-yourselfer or a first-time home buyer, you’ll discover helpful advice and insights to approach this project with assurance.

Prior to getting into the specifics, it’s critical to comprehend the significance of correct plastering for fireplaces and stoves. Plastering has functional benefits in addition to aesthetic ones, like halting heat loss and protecting against structural damage. Plaster maximizes heat retention and reduces energy waste by forming a seamless barrier that helps keep the stove or fireplace at a constant temperature.

Plastering also protects these heating fixtures from normal use’s wear and tear and strengthens their structural integrity. High-quality plastering helps stoves and fireplaces last longer by protecting against moisture and fortifying the underlying structure, guaranteeing that they will continue to be both aesthetically pleasing and functional for many years to come.

Why is it necessary to plaster the oven

Why is plastering brick structures necessary? There are various reasons why fireplaces, and stoves in particular, are finished:

• The plaster creates a hermetic layer, which, in the case of cracking of the pantry in the seams between the bricks, will not allow carbon monoxide to penetrate the room.
• Plaster gives accuracy and improves the type of structure as a whole.
• The plaster mixtures also performs a hygienic role. So, over time, in the seams, especially if a solution for masonry made of natural materials was used, colonies of insects or microorganisms harmful to humans may appear, which will be difficult to get out quite difficult.

What tool is required to work

You cannot plaster without the use of specialized tools. For this kind of procedure, you’ll need:

A collection of tools for plastering a fireplace

• Plastered hammer. It is used to score special plaster nails.
• A hammer-whip. It is necessary for shock on the Trojan, chisel or gear.
• Scissors cutting metal – they are used to cut the reinforcing mesh. Such scissors have a special shape that allows you to save your hands from injuries.
• Kelma (trowel). This tool is applied and distributed by the solution along the upper walls of the furnace.
• Spatulas use different sizes – they apply and smooth the solution in complex places.
• Grater . The surfaces are smoothed with this tool, removing serious defects. It is used for black grout.
• The half is used for better alignment of plastering for painting.
• Glade. This tool is similar to a half -ather and is used for the same, but has a working surface of soft rubber.
• Different sizes of the brush are designed to clean the tools, applying plaster and giving decorative texture.
• The chisel is made by the notch when preparing walls for plaster, if the reinforcing mesh is not used.
• Metal brushes that are designed to clean surfaces when removing old coatings.
• Plumb – it is necessary to check the evenness of the vertical laying of the plaster.
• Construction level is used for reconciliation of verticality and horizontalness of planes.
• Rule – with this tool, the large areas of surfaces are aligned on the beacons.

How to prepare a heat -resistant mixture

The plaster layer’s ability to withstand the constant temperature changes that the structure will experience is one of its most crucial characteristics. As a result, unique specifications for the caliber and ratios of its constituents are placed on such a solution.

Different proportions of multiple ingredients can be combined to create independently prepared plaster mixtures. Both simple and complex describe them.

• Simple compositions include a solution consisting of sand and clay.
• Complex solutions are considered those that consist of more than two ingredients (for example, special chamotte clay).

After passing through a tiny sieve to remove any contaminants, each mixture’s component parts should be joined together in a dry form. The mixture is then thinned out until it has the consistency of thick sour cream.

The choice of clay for the solution is crucial because the plastering layer’s overall adhesion is influenced by the clay’s quality and fat content. Sand content in the composition can be raised if the clay is fat.

The reinforcing element, which can be either a stump, crushed fiberglass, asbestos, or finely chopped straw, is another crucial part of the solution. Naturally, it is preferable to use natural, eco-friendly materials rather than asbestos, which is harmful to people’s health. A tiny bit of salt is added to the mixture by certain stovers. Although it is unlikely to have a detrimental effect on the solution’s quality, it will serve a hygienic purpose because insects cannot begin to grow in a frozen solution.

Proportions

As previously stated, a number of ingredients contain complex solutions, and the appropriate amounts of each ingredient must be used. The stovers (compound) use the following recipes:

• Asbestos, clay, sand – 0.2: 1: 2.
• Asbestos, clay, lime, sand – 0.1: 1: 1: 2.
• Portland cement, sand, asbestos, clay – 1: 2: 0.1: 1.
• Gi PS STRIVE, GASHENE LIKE, FIRE -WEE, SAND – 1: 2: 0.2: 1.

When preparing this kind of solution, keep in mind that gypsum solidifies more quickly than the other ingredients. It starts to solidify into a monolith five to seven minutes after kneading. Lime tastes great with gypsum because it adds strength. However, because of its peculiarities, it must be grasped rapidly, a small amount of solution must be kneaded with water, and only after it has developed can the preparation of the subsequent portion be started.

• Asbest, Gashenic lime, sand – 0.1: 1: 2.

Preparatory work

It is necessary to take certain preparatory steps before applying the plaster directly to the folded structure. The plaster won’t adhere well to the surface without them, creating an environment that isn’t conducive to better adhesion.

• If there is an old plaster on the stove or fireplace, it must be removed and well cleaned of the remaining dust.
• If the furnace is new, it also needs to be cleaned, since on the surface of the new structure there may be particles of dust or dirt, which will interfere with a good sticking of the plaster mixture.
• Further, both in the first and in the second case, it is necessary to deepen the seams between the bricks, about 0.7 – 1.0 centimeters. It will also help plaster better to catch on the surface.
• After deepening the seams, the walls are again cleaned of dust.
• The next step is the process of covering surfaces with a special primer.
• If it is planned to put a few layers of plaster, then sometimes tightening the structure with a reinforcing metal mesh with medium -sized cells. It will better fix the layer of plaster on brickwork and extend its life with regular thermal drops. The grid is fixed using nails with large hats that are driven into the seams.

It is possible to add the necessary decorativeness to plaster.

When relief drawings are placed on a smooth or rough surface, the stove can be plastered perfectly smooth, with imperfections, or a combination of the two techniques.

In order to plaster a stove made of ceramic or stone tiles, a thin layer of plaster solution is applied.

Prosc"s pro -preparation of the solution, immediately before applying

A properly blended solution is another essential component of a job well done. It is frequently prepared with a drill that has a mixer nozzle installed.

But there are a few other things you must do in advance of kneading:

• If clay includes clay, it requires soaking, approximately 24 – 36 hours. It is necessary that it be well soaked in moisture and swells. If clay absorbs water, then you should add fluids from time to time .
• The sand is necessarily sifted, otherwise large fractions will interfere when plastering work. Another moment of manufacturing a benign solution is the use of only dry sand in it – this will help correctly calculate the proportions.
• An excellent plasticizer for compositions can be called lime. Its good viscosity contributes to adhesion, and this is important for the plaster mix used for fireplaces and furnaces. Including lime in the solution, you must also remember that it has the ability to freeze quickly enough.
• The cement brand is usually chosen, based on its strength. The M-400 is well suited. Its solidification begins 15 to 20 minutes after it kneads, but this pro -ss is about 3 to 4 hours. The final setting occurs after 10 – 12 hours. The solution applied to the walls reaches the calculated high strength only after 25-30 days.

The process of plastering a stove or fireplace with your own hands

The first way

The minimum thickness of the plaster layer on the furnace walls should be 8 to 10 millimeters.

• In order not to be mistaken and apply it evenly, they install special beacons. They are fixed on a non -weed layer of gypsum, which quickly freezes and makes it possible to continue to work further.

• The next step is to wet the masonry with water – this is done to better stick the solution.
• Next, the first layer of plaster is applied. It should have a creamy consistency. This layer is pierced by intense movements so that the solution penetrates into all masonry cracks. The plaster applied is necessarily allowed to dry.
• The next layer should be 8 – 10 millimeters. It is applied and aligned by beacons. It is left until completely dry.
• Then control alignment occurs, this layer is given time to dry.
• Until the surface has completely dried up, it is polished, using the mature moistened in water. For uniform drying of the plaster, the plastered stove is covered with a damp burlap. When it dries, it is carefully removed, and all the cracks that appear must be immediately wiped and smooth out.
• Separately, I must say about the removal of the corners of the furnace. They are arranged by fixing the angle of the rail on one side, and its uncovered part is removed along it . After drying it, the rail is removed and fixed to the aligned side, now the second side is aligned.

Preferably, the stove or fireplace’s corners have a slight "twist."

• It is best to make corners somewhat rounded, so they will be safer for young children and will not be prone to chips, for example, during the rearrangement of furniture.

The second method

Plaster is also applied on a metal mesh that strengthens the structure in a second method.

Applying plaster to a tiny net

• The grid is fixed so that it departs from brickwork by two to three centimeters. To do this, a wire or rail of the desired thickness is placed under the grid.
• Plaster is also applied in several layers to up to style of complete closing the mesh with a solution. This method has an advantage over others in the fact that alignment on the grid is much easier, and the finish is more durable, reliable and more durable. But it should be noted that at a price it will cost a little more than the first finish method.
• Next, the plaster is dried, the cracks are smeared, then the surface is polished – and it is ready for further decoration.

Decoration

If you have already made the decision to plaster a stove or fireplace, take into account a few crucial steps in the procedure to avoid having to start over after the first firebox.

• You can not immediately plaster the newly erected structure. And even when it dries well, you need to give time to shrink the masonry. To do this, the furnace should operate for two to three months, and only after that you can engage in its transformation.

Several methods for achieving the necessary surface texture in plaster

• Often after drying the plaster, resort to its coloring. This process must also be carried out correctly by picking up the paint. It must be on water -based, since the compositions containing chemical solvents or an Olyphus will emit unpleasant odors into the room, which, in addition, are also harmful to health.
• Without waiting for the complete decorative decoration, it is covered with the chosen color or painted with several shades.

Plastering fireplaces and stoves improves their safety and efficiency, which are two important aspects of home design. We have covered a wide range of plastering topics in this post, from supplies and setup to methods and final touches.

It is crucial to realize how important it is to choose the appropriate materials. Every option, from more contemporary cement-based mixtures to more conventional lime-based plasters, has advantages and disadvantages of its own. There is a plaster that will work for you, regardless of whether breathability, flexibility, or durability are your top priorities.

The basis for a successful plastering project is preparation. It is imperative that the surface be thoroughly cleaned and primed, that any imperfections or cracks be repaired, and that the proper base coats be applied. A seamless and durable completion is ensured by carefully planning ahead.

Using technique effectively is essential to producing results that are professional. Plastering is a skill that takes patience and practice to master, from applying the material in thin, even coats to using the appropriate tools. Applying a spray or trowel by hand, consistency and careful attention to detail are essential.

The finishing touches complete the project and turn an otherwise functional stove or fireplace into the room’s main attraction. The final layer of plaster gives your investment character and longevity, adding everything from decorative textures and patterns to specialized coatings for heat resistance and moisture protection.
