What is the difference between plaster and putty? These materials are intended primarily for leveling surfaces. Usually, in the process of performing capital work, craftsmen need both. However, before proceeding with specific actions, it is recommended that you familiarize yourself with the distinctive features of these materials and determine the areas of their possible application.
Plaster
What is the difference between plaster and putty and primer? This building mixture is used not only to level the surface of the walls, but also to protect them from the penetration and accumulation of moisture. Plaster is also used to improve the thermal insulation qualities of coatings.
The structure of the plaster is coarse-grained. Therefore, it is convenient to apply it on surfaces that contain significant irregularities and depressions. Often, in order to figure out how putty differs from plaster of a certain type, it is enough to familiarize yourself with the information that manufacturers place on the package. In this case, the plaster may differ in the presence of properties,suitable for basic and decorative finishing work.
Putty
It is a plastic mass, which is an effective tool for removing small and deep scratches, crevices on the surface of the walls. The difference between putty and plaster is the level of graininess. For plaster, this indicator is much less, which gives the mixture additional viscosity.
When filling depressions and voids, putty does not change in volume, bubbles and cracks do not form on its surface. Here, gypsum, ordinary cement or polymeric materials can act as binders. Surface treatment with putty allows you to create the most even, smooth layer on which it is convenient to glue wallpaper, apply paint.
Distinctive properties of plaster and putty
What is the difference between plaster and putty? If we talk about putty, then it is assigned the task of not only filling up flaws on a flat surface, but also smoothing the structure of the plane as much as possible, making it homogeneous.
Separate starting and finishing putty. The first type is used for quick sealing of cracks and other minor defects. Starter mixes are coarser than finish mixes. The latter option is used when smoothing the surface for painting or wallpapering.
What is the difference between gypsum plaster and putty? The structure and properties of gypsum plasteris a radically different composition. The substance is used to cover bare brick or concrete walls, as well as foam blocks. Therefore, plastering is a rough finish.
If we talk about how plaster differs from putty, then the nature of the application of these substances should also be noted. According to experts, plaster should be applied with a layer of no more than 5 cm. Otherwise, the coating will inevitably slide down. To prevent this from happening, when applying plaster, special meshes are often used, which you will not see in the process of coating surfaces with putty.
Conclusion
In conclusion, I would like to pay more specific attention to how plaster differs from putty:
- Putty has a fine-grained structure, while plaster is a coarse-grained mortar.
- The main purpose of plaster is to level surfaces and apply a monolithic layer up to 5 cm. Putty, in turn, is used in cosmetic, surface wall decoration and the elimination of defects no more than two centimeters deep.
- Plaster is applied as an intermediate layer leveling bare walls. Putty is the final layer before the final coating of surfaces.
- In order to avoid unevenness and slippage of the coating, plastered walls are absolutely not recommended to rub with abrasives. At the same time putty is not afraid of contact with abrasiveskins.
- It takes about two days on average to completely dry the plaster. Less than a day is enough to dry the putty under normal conditions.
