Sand sponge is a foam sponge, impregnated with various sizes of sand. People can use sponge as a sand grinding tool to smooth various surfaces. Many hardware and craft shops carry sand sponges and accessories, such as brackets, for ease of use. They can be useful tools at home or in the workshop.
Sandpaper is often used in the trimming of dry walls. Compared with sandpaper, using sandpaper has many advantages. One of the biggest benefits is that sand sponges can be cleaned to remove clogged materials, and they take a long time. As foam and sand wear out, continuous layers are uncovered, allowing single sponges to be used on many occasions and in various settings. Washability is also a great advantage when people are engaged in projects that are easy to block sandpaper, such as sandpaper, paint, putty and similar materials. The side of the sponge held by the user is made of sand free, which will not stimulate the hand. Due to the high flexibility of sand sponge, it can be used for leveling or contour surface. Unlike sandpaper, it will not crack or wear and bare dew point. For extended sanding projects, the use of brackets can make grinding more comfortable because it can reduce hand cramps and friction joints. Most sand sponges are designed to be wet or dry. Some applications produce less dust and are more suitable for wet sand. Sponge dry sand can also have less dust than sandpaper, because the sponge will collect dust and debris, which can be washed away later. Wood, plastic, metal, clay and many other materials can be polished with sand sponge, from the preparation of paint to the surface treatment of handmade tables or cabinets. Frosted sponges come in a range of grades from coarse to fine. Like sandpaper, it is best to start with coarse grains and then roll slowly and continuously towards fine grains. Although this method takes a long time, it often produces the best results, resulting in smooth, even surface without gouges and rough spots. Some companies make colored sponges so that different gravel can be identified at a glance.
