Choosing the right sandpaper for the job can be confusing, as there are various grits and types available. This detailed guide will tell about the perfect sandpaper for wood before painting:

Understanding Grits

Coarse to Fine The grit of sandpaper refers to the size of the abrasive particles on its surface. Sandpapers are available in a range of grits, starting from coarse to fine.

Coarse grits have larger particles and are suitable for heavy sanding and removing rough surfaces or old paint.

Fine grits have smaller particles and are used for smoothing surfaces and preparing them for paint.

When selecting sandpaper, consider the condition of the wood surface and the amount of sanding required.

Coarse Grits (40-60)

Initial Sanding For initial sanding or removing rough surfaces, start with coarse-grit sandpaper, typically in the range of 40 to 60.

This grit is ideal for tackling imperfections such as bumps, unevenness, or previous paint layers.

It quickly strips away the old paint and roughens the surface, providing a good base for further sanding. Remember to sand in the direction of the wood grain to avoid scratches.

Medium Grits (80-120)

Smoothing the Surface After the initial sanding, transition to a medium-grit sandpaper, which usually falls within the range of 80 to 120.

Medium-grit sandpaper is effective at smoothing out the wood surface, removing scratches left by the coarse grit, and creating a uniform texture.

It helps to level the surface and prepares it for finer sanding and painting. As before, sand along the grain for the best results.

Fine Grits (150-220)

Preparing for Paint As you progress towards the final stages of sanding, switch to fine-grit sandpaper, typically between 150 and 220.

Fine-grit sandpaper is used to refine the surface further, removing any remaining imperfections, scratches, or roughness. It creates a smooth and even texture, ensuring that the paint adheres evenly.

This step is crucial for achieving a professional-looking finish. Lightly sand the surface, again following the direction of the wood grain.

Extra-Fine Grits (320 and Above)

Between Coats and Final Touches In certain cases, when an exceptionally smooth surface is desired, you may opt for extra-fine grit sandpaper.

These sandpapers have grits starting from 320 and above. Extra-fine grit sandpaper is typically used between coats of paint to remove any dust particles or small imperfections that may have appeared during the painting process.

It also helps to create a smoother finish on the final coat. However, it’s important to note that using extra-fine grit sandpaper may not be necessary for all painting projects.

In addition to the grit, you should also consider the type of sandpaper. There are three common types: garnet, aluminum oxide, and silicon carbide.

Garnet sandpaper is suitable for light sanding and is often used for fine woodworking. Aluminum oxide sandpaper is versatile and can be used for both wood and metal surfaces.

Silicon carbide sandpaper is highly durable and is often used for sanding harder materials like glass or stone. For most wood painting projects, aluminum oxide sandpaper is a good choice due to its versatility.

What Grit Sandpaper to Scuff Paint to Repaint?

It depends on the type of paint you are using. For most paints, a 120-grit sandpaper is usually a good starting point for scuffing the surface.

However, you may need to use finer grit sandpaper if you are using harder paint, such as epoxy paint.
