Not all types of sandpaper are created equal. This is something every home owner should be aware of. Instead, these tools are broken down into many types and sub-types, and making the right choice can mean the difference between a DIY disaster and a DIY masterpiece.
You can buy sandpaper in New Zealand from various online sources.
In this short article, we will discuss about the two main characteristics that classify sandpaper materials, then we will discuss some of the sub-classifications that are popular among them. We'll talk about the implications for DIY projects too, so listen closely.
The first category included in sandpaper is called "grain". In general, this property indicates how coarse or fine the abrasive layer will look. Higher grit grades represent a smoother finish, while lower values represent a coarser finish, ideal for harsh conditions.
The scale for evaluating sandpaper grains varies between 40 and 600. The lowest value (between 40 and 180) applies to treating rough surfaces to improve the adhesion of paints and varnishes. Then the middle layer (from 181 to 320) is ideal for removing stains from furniture without damaging the wood surface.
Finally, the highest mark (321 to 600) is used for sanding the finish of the window, usually to remove brush or finger marks on layers. This works especially well if you are looking for a smooth surface.
The second category is the type of abrasive used to make sandpaper. Common types are glass, alumina, green garnet, and silicon carbide. This material not only affects the quality of the sand grains, but also has several properties that distinguish them.
