Plastering a wooden house serves purposes beyond aesthetic enhancement. It’s a useful technique to shield the building from the weather, extending its lifespan. Plastering, both inside and outside, can protect wood from deterioration, insects, and moisture over time.
Plastering, when done properly, also adds an insulating layer, which aids in preserving a consistent interior temperature. This makes it an energy-efficient option for homeowners as well as a preventative measure.
Knowing the proper plastering techniques and materials is essential, whether your goal is to give your wooden house a new look or just strengthen its weather resistance. This tutorial will walk you through the steps required to plaster the inside and outside of your wooden house.
| Finishing Inside | Finishing Outside |
| Interior plaster helps to protect wood from moisture and enhances the home"s insulation. | Exterior plaster shields the wood from weather damage and provides an additional layer of thermal insulation. |
| It creates a smooth surface for painting or other decorative finishes, improving the aesthetic appeal. | Exterior plaster can be textured or painted to match the desired look, adding curb appeal to the house. |

Plaster protection for wooden houses is a good way to make them more resilient and appealing. It offers a robust shield against weather, moisture, and pests and lets you choose from a number of beautiful finishes. This article examines the advantages and methods of plastering wooden homes’ exteriors and interiors, providing helpful advice to guarantee a durable and attractive finish.
Why plaster wooden walls
Even with all of their benefits, wooden homes constructed of beams and logs have a major disadvantage: the material ages. Plastering the walls is one way to shield them from outside influences. Additionally, plaster over wood levels the ceiling and walls and adds to the facade’s insulation.
Furthermore, plastering can avoid:
- drying out of wooden walls;
- mold formation;
- rotting;
- damage by insects and rodents;
- wood fire.
It is crucial to remember that plastering a wooden house can only be done a year after it is built because shrinkage takes time. Frame houses are inherently rigid constructions that can be finished right away after construction.
Choosing plaster for wood
Nowadays, a vast array of finishing materials with varying types and compositions is available. Plaster is not an anomaly. We’ll talk about finishing wood walls both inside and outside the house in this article.
Cement-based composition
You can create a surface that is resilient to frost and precipitation by using cement mortar. This is also the least expensive option among the mixes that can be purchased. Two types of cement-based plaster are available:
Cement and sand. a sturdy and reasonably easy choice. Frequently used to finish exterior walls. Cement, which comes in different compositions, is the foundation of this plaster. The grades, with M500 being the highest, reflect this. Stores carry a variety of component combinations; the following ratios of mixtures are used for plastering: 4–5 parts sand and 1 part cement.
Select medium-sized sand when preparing the plaster solution by hand. Small sand grains weaken the plaster and increase the likelihood of cracks. The wall appears rough due to the large particles; this composition is only appropriate for rough finishing.
The mixtures contain additives in addition to the primary ingredients that improve the solution’s plasticity. Redispersible copolymers and powders are used to make plaster in factories; the packaging describes this composition as polymer-cement. The solution’s plasticity, wear and load resistance, water repellency, frost resistance, and other qualities are all increased by these additives.
Cement-lime plaster. includes sand, Portland cement, and slaked lime as ingredients. has a higher vapor permeability and is lighter than cement-sand plaster. The lime mortar is stored for two weeks following slaking. For the chemical reaction to complete and prevent the plaster layer from swelling, this is required.
Since lime is a great way to get rid of mold and bugs, lime-cement plaster is good for facade work and is used as an antiseptic for wood.
Gypsum plaster
A unique filler and polymers are included in the composition in addition to the primary ingredient. Compared to other types, this plaster is more plastic and is consumed less. Polymers enhance the surface’s and the solution’s adhesion qualities.
Solvable mixtures containing gypsum are the form in which this type of plaster is sold. The solution is brought to the appropriate consistency by adding water: a thick mixture for leveling the walls and hiding cracks, and a more liquid one for the top layer.
One of gypsum plaster’s drawbacks is its lack of strength. As a result, it is only used for interior decoration and not for exterior work.
Merely little portions of the mixture are prepared. It should be noted that the material keeps its flexibility for approximately half an hour.
Clay mortar
One of the earliest methods for shielding wooden walls from wind and rain is clay plaster. Today, this natural material is still widely used because it is inexpensive, easy to use, and health-safe. Modern cottage interiors are increasingly featuring clay walls and floors.
You can purchase pre-made dry clay mixtures like Ш-77 and GlinKo.
The following ingredients are used to prepare a plaster solution: clay, water, sand, and sawdust from oak or alder trees, which are conifers.
The fat content of clay is an important property for work. Although fat clays cling well, they dry unevenly and fracture. They are thus diluted using sand. After drying, lean clay solutions crumble and readily absorb moisture.
There are multiple methods to assess the mixture’s readiness. For instance, a three to four centimeter clay ball is rolled and compressed between two boards. In the event that there are none at all, the material is bold. If the ball dispersed, thin clay would follow. The desired result should be a cake with tiny cracks around the edges.
- clay-sand composition;
- clay with an admixture of fiber;
- clay with wool, felt, sawdust, etc.D. (to choose from).
It is convenient to use this material for independent wall plastering. It requires little preparation before use and can be applied with ease.
A wooden house can be effectively and dependably protected from both internal and external factors with plastering. Not only does it provide a beautiful finish, but it also protects the structure from moisture, pests, and fire hazards, increasing its longevity.
You can prolong the life of your wooden home significantly by selecting the proper plaster and applying it correctly. Plastering offers a robust layer of protection while allowing the wood to breathe, preventing problems like rot or mold, whether you’re working on the interior or exterior.
Plastering is ultimately a crucial step in maintaining the integrity and beauty of your wooden house, not just a decorative one. You can take advantage of wood’s warmth and charm and the peace of mind that comes from knowing your house is well-protected if you take the proper approach.
