Old-fashioned putty recipes

You can make the solution on your own using medium-fat fireclay.

• gypsum, sand and lime in proportions of 0.3: 2: 2;
• clay, sifted river sand and lime in a ratio of 1: 2: 2;
• clay, sand and cement in proportions of 1: 2: 0.3.

It is advised to combine the solution with low-fat milk when working with lean clay. Lime is added to the mixture to help lighten the clay mass, and chalk and milk are used to create a consistent white color for the putty solution. Fibers can be added to the composition in amounts up to 10% of the total mass.

The coating hardens more quickly when gypsum is added to the mixture, which is why these solutions are diluted slightly. The amount of fat in the clay determines the volume of sand.

How to putty correctly

• preparing surfaces for work;
• priming;
• reinforcement;
• applying plaster;
• grinding the plaster coating;
• decorative finishing of the stove.

Preparation for work

There are preparatory steps involved in putty application. The surfaces that require cleaning and processing are measured, and the volume of putty material is calculated while considering the ratios mentioned in the instructions. Next, a thorough cleaning is done. In older buildings, the plaster layer needs to be removed, and the joints between bricks need to be cleaned down to a depth of 10–15 mm. The stove is heated before plastering work is begun.

Reinforcement

To strengthen the plaster layer and lengthen the structure’s lifespan, work on strengthening the stove’s surfaces is required. Burlap, self-tapping screws, or reinforcing metal mesh are used in the work. Screwing in self-tapping screws up to 75 mm in length on challenging stove sections is a common way to reinforce the stove. The caps should be raised 10 to 15 mm above the stove’s surface.

Putting burlap on the stove’s walls is another way to reinforce them.

The fabric needs to be pre-soaked in the liquid clay solution that will be applied to the stove’s frame. After that, the burlap is carefully smoothed out and glued to the surface.

One alternative to the burlap is a fine-mesh metal mesh. At the laying stage, a 3 mm wire must be laid in order to secure the steel mesh.

Applying the composition to the stove or fireplace

Putty is applied to stoves and fireplaces using pre-primed surfaces. When preparing surfaces, it is best to use a primer that has heat-resistant properties.

It is advised to use heat-resistant putty first, and then finishing. You will need a 10 cm spatula for the task, as it is used to apply the initial composition. Cracks are cleaned and the surface is leveled. Using a wide spatula, the finishing composition is spread out once the starting mixture has solidified. Beacons must be installed in order to level and create smooth surfaces around large stoves. Applying a fireproof primer composition is necessary once the finishing putty has dried. After two weeks of drying out the stove, a test fire is conducted.

Decorative finishing of the stove

• special putty with subsequent painting;
• natural stone (marble tiles, granite);
• decorative plaster;
• with imitation of stone breeds;
• metal sheets;
• glass with heat -resistant characteristics;
• porcelain granite;
• ceramic tiles;
• decorative bricks.

One must remember that putty used in furnaces and other finishing materials needs to be heat resistant.

For stoves and fireplaces, selecting the proper putty is essential for both functionality and safety. Heat-resistant putties are perfect for surfaces exposed to direct heat because they are made to withstand high temperatures without breaking or losing their adhesive qualities. They offer a tough coating that is able to withstand the extreme heat generated by fireplaces and stoves.

Due to its resistance to temperatures as high as 1000 degrees Celsius, heat-resistant putty is a preferred option. This qualifies it for usage in environments where intense heat is a constant. Due to its flexibility, it provides a long-lasting solution for preserving the structural integrity of your fireplace or stove in the event of heat stress.

Conversely, fireproof putty goes one step further by stopping the spread of fire in addition to withstanding high temperatures. This kind of putty is especially crucial for preventing your stove or fireplace from starting a fire. Through the creation of a seal, flames can be contained and kept from spreading to other areas of the house.

It’s important to take your installation’s particular requirements into account when choosing putty for your stove or fireplace. While fireproof putty adds extra safety by containing possible fires, heat-resistant putty works well in areas that are frequently exposed to high temperatures. Depending on your priorities for fire safety and heat resistance, you can choose between the two types, each of which has unique benefits.
