Having the appropriate tools can significantly impact the quality of your wall finish, ensuring a smooth and flawless appearance. A crucial instrument for grouting putty is the grinding mesh, which is made of sand. This particular mesh is intended to smooth out putty’s surface so that it is flawlessly level and prepared for the subsequent stages of your project.
The putty is smoothed out and any excess material is removed by gently abrading it with the grinding mesh. Your walls will look better after this process, which also gets them ready for painting or other finishing touches. The final result can be improved and the effort required can be greatly decreased by using the appropriate mesh.
Selecting the right kind of mesh is essential. Meshes are available in different grit levels, each appropriate for a particular grouting stage. Knowing which grit to use and how to apply it properly can guarantee results of a professional caliber while saving time. This post will discuss the various kinds of grinding meshes, how to choose the best one, and application advice for getting the best wall finish possible.
| Type of Mesh | Description |
| Aluminum Oxide Mesh | Durable and long-lasting, suitable for smoothing rough surfaces. |
| Silicon Carbide Mesh | Efficient for heavy-duty sanding, known for its sharpness and strength. |
| Fiberglass Mesh | Lightweight and flexible, ideal for delicate surfaces. |
| Diamond Mesh | High performance, perfect for very tough materials. |
| Nylon Mesh | Cost-effective and versatile, good for general-purpose sanding. |

Functionality of an abrasive mesh for grinding
Depending on the application, a different level of graininess is used in putty grinding mesh selection. The cloths work best on ceiling slabs, windows, door beams, arches, niches, and other difficult-to-reach areas.
The abrasive material offers superior surface treatment while maintaining its elasticity. The perforation in the base increases the mesh’s functionality. Paint, primer, plaster, and building dust particles are eliminated through the cells without delaying the panel processing process.

Advantages of mesh over sandpaper
- ease of use;
- the base of the material has water-resistant characteristics;
- small dust formation;
- abrasive is represented by materials with different fraction sizes;
- high productivity of the sanding cloth;
- perforated sheet;
- wear resistance;
- universality of application, because.. abrasive is used to process all types of building materials;
- products are manufactured by manufacturers in a wide range;
- easy cleaning;
- manual and machine sanding is possible;
- affordable cost;
- high profitability.
Disadvantages of a mesh for sanding
- low strength of the base;
- rapid wear of the material;
- the need to purchase special attachments for work.
When grouting putty, a grinding (sandy) mesh tool is a must for a polished, smooth finish. In order to ensure a smooth, even surface and to remove any imperfections, it helps to sand down the putty. This procedure not only makes the grouted area look better, but it also makes the final coat of paint or finish more durable and adherent. You can greatly increase the caliber and durability of your grouting projects by being aware of how to use and apply grinding mesh properly.
Marking and determination of the grain size of the mesh for cleaning the finishing putty
Grain size, represented by the letter "P" in GOST, is the primary feature of the mesh. The numbers (P60, P140, etc.d.) that follow the letter represent the density of abrasive particles per unit area.
- at the initial stage of work, materials marked P22-60 are used;
- for primary grinding, meshes P80-120 are used;
- final processing is carried out with abrasives P240;
- for jewelry polishing, meshes with a minimum level of abrasiveness P1200 – P2500 are in demand.
Types of abrasive dusting of grinding meshes
The type of material, grains, and abrasive to use when grinding surfaces determine the appropriate mesh to use.
- corundum;
- siliceous;
- emery;
- electrocorundum;
- pumice;
- diamond.
Sandpapers for grouting come in two varieties: closed and open. Meshes with a continuous abrasive coating are necessary for polishing hard panels. The second type of cloth is ideal for bases with a soft structure because it has 40–60% of its surface covered in grains.
The grouting material’s grain size can range from 80 to 600. Meshes with the P 120–220 marking are the most widely used for surface treatment.
- coarse (P 40-80 and grain size 800-315 microns) – intended for initial sanding of surfaces with a hard structure;
- medium (marked P100-180 and abrasive particles 200-100 microns in size) – used for primary treatment of panels, preparation of bases for gluing wallpaper materials and painting;
- fine (with grains less than 100 microns and P200-400) – recommended for finishing puttying and further application of glossy dye (this material helps to level walls, partitions, eliminate small bulges, cracks);
- the smallest mesh sandpapers are released under the marking P600, the cloth is intended for final grouting of coatings with a soft base.
The characteristics of the floors and wall panels are taken into consideration when choosing the material. Meshes with fractions of 40–80 are used to sand the dried layer of starting putty and remove any irregularities. Abrasives with a grain size of 120–180 are bought to clean a durable coating. It is necessary to rub thin-layer finishing plaster mixtures with cloths rated P 220-280.
The wallpaper sheets’ thickness is considered when prepping walls for adhesion. Because thin cloths need a flat base, fine-grained abrasive (P220 and above) is utilized.
For putty surfaces, a grinding mesh is a necessary tool for a uniform, smooth surface. You can quickly and effectively remove flaws and produce a perfect base for painting or other finishes by using a sandy mesh. Choosing the appropriate grit size and applying consistent pressure while sanding are essential for efficient use.
The degree of surface roughness determines the proper grit size to use. Finer meshes work best for final smoothing, while coarser meshes work well for initial sanding to remove larger imperfections. Reaching an impeccable smooth finish can be facilitated by working through progressively finer grits.
Technique is also very important. To avoid leaving behind noticeable lines or uneven areas, sand in a circular or overlapping pattern. Make sure you’re attaining the appropriate level of smoothness without over-sanding by periodically assessing your progress.
All things considered, using a grinding mesh for grouting putty is a simple procedure that can greatly improve the caliber of your completed surfaces. You can produce results that look professional and endure over time with the correct tools and methods.
