THE DAILY GRIND

Learn how to achieve smooth finishes with the right abrasives.

Nothing elevates a project quite like a perfectly smooth finish. Whether you're painting a door, refinishing a piece of furniture, or restoring wooden floors, sanding is often the step that determines how professional the end result looks. Yet many DIY enthusiasts see sanding as a dull chore — just a matter of rubbing a surface until it feels “good enough.” In truth, there’s more to sanding than meets the eye. Understanding abrasives, grit sizes, and technique can make a startling difference to your finished project, saving you time, energy, and potential frustration later. Below, we'll explore what makes sanding such a vital skill and how you can approach it with confidence.

The importance of sanding

A surface might appear clean at first glance, but it can still have bumps, dents, or residue that stops paint or varnish from adhering properly. Sanding smooths out these imperfections, allowing subsequent layers — such as primer, paint, stain, or sealer — to bond effectively. Imagine painting a wall covered in bumps and divots: the paint might hide some flaws, but the overall look still suffers. By taking time to sand properly, you create a solid foundation that ultimately leads to a neater, more durable finish. The effort you invest up front often pays off by reducing the need for repeated coats or fixes later.

Sanding also helps remove old finishes. For example, if you're revitalising a piece of wooden furniture with layers of chipped paint, sanding clears away the uneven patches so the new coat can shine. Beyond aesthetic concerns, a properly sanded surface often holds up better to wear and tear, because the new coating can grip onto the wood more effectively. In short, sanding is about more than appearances - it’s about longevity and reliability, too.
