Sanding: which grain to choose?

Sanding is part of a painter's daily work. For example, we sand to remove old layers of paint or rust. Bare wood also needs sanding. Even with new coats of paint, sanding is recommended to ensure good adhesion with the next coat.


In short, paint jobs are also sanding projects.

Coarse or fine grain?

Now that you know the importance of sanding, you probably want to know what kind of sandpaper you need. Choosing the right grit size is essential. Grit size is represented by a number. The lower the number, the coarser the grit and the more you sand the surface.

A coarse grit is suitable for intensive sanding work, such as removing old layers of paint or rust. A medium grit is used to prepare the bare surface, and a fine grit to obtain a beautiful finish.

Compare sanding to a cycle race. You'll get the best results if you sand in several stages, using different grits. Below is an overview of grit sizes and the corresponding tasks.

Explanation of grit sizes

Grit size Purpose
60 - 80 To remove old layers of paint or rust.
80 - 120 For sanding bare / new wood.
120 - 150 For sanding existing paint layers in reasonable condition.
180 - 220 For sanding up good paint layers. For example, if you want to apply a matt paint on a glossy paint layer, you should first sand with these grit sizes.
240 For sanding between new paint layers to achieve better adhesion with the next layer.

Have you found the grit you need? Buy sanding sheets in the grit you want here. Prefer sandpaper that feels good in your hand? ProGold Softpad is an excellent choice. It's also available in a range of grit sizes.

Sandpaper for different surfaces

Red, white or black. You can also tell the difference between sanding materials by the colour of the paper. And these colours betray the surface you can sand with this paper.

Red sheets are made for sanding bare wood, chipboard and metal.

White abrasive sheets, on the other hand, are used for existing coats of paint, mastics and coatings. What's more, these white sheets last longer because they don't sag as quickly. In other words, the grain relief remains intact for longer.

Black sanding material is also often found. In general, these black sanding blocks can also be used for wet sanding. The advantage is that you don't inhale any dust, so you don't have to wear a mouth mask.

Cleaning and degreasing: how to properly prepare the surface

A grease-free and clean surface is an absolute prerequisite for a successful paint job. Paint is not a great fan of dirt and grease - sorry John. A greasy or dirty substrate interferes with the paint's capacity to adhere properly, which might end up resulting in flaky paint or discolouration later on. Thorough preparation by cleaning and degreasing will prevent this, as you create the perfect base for a perfect result.
