How to Select the Right Sand Paper before Painting

When you are looking for the best finishes to your home’s walls, you should always choose painting services in Sydney. However, there may be many of you who like the DIY approach better than hiring professionals. Sanding is a crucial task before painting. It helps in removing the remnants of existing paints from the walls. Though many homeowners tend to take sanding and especially the selection of proper sand paper very lightly, it is in fact a very crucial aspect. Often the sanding decides how well your new paint stays on the walls and how good the finishing is. This is why professional painters in Coogee never take the selection of sand paper lightly.

Today, quality sand paper is made from many materials. One of the things you could be amazed by is: modern day sand paper does not consist of any sand. In the earlier times, a partial quantity of white sand was used in the manufacturing of sand paper, but not anymore. The white sand has now been replaced by natural or synthetic abrasives such as aluminum oxides and garnet. Nowadays, there are some alternatives to sand paper to such as steel wool. The steel wool is more popular among the painting services in Sydney as it can be used for a range of materials.

When you go to the market to purchase quality sand paper, you have to be aware of the characteristics of sand paper. Two foremost characteristics of sandpaper are grit and coat. Grit is measured by the amount of particles within a piece of sand paper that could pass through a filter that is about one square inch in size. Grit number can be as low as 12 and may be as high as 600. But the commonly available sand paper in the market has a value somewhere around 30-220.

Coating is a measure of how dense the abrasive is on a piece of sandpaper. Open-coated sandpaper has a spread that is about 70% of the surface area.

Make sure you get these details right when selecting sand paper.
