Sometimes is the tasks that no one wants to do that makes the biggest difference, and in the case with sanding this couldn’t be any closer to the truth. Whether your sanding wood, walls, or a car, taking the time to do a job well done means methodically sanding out all the blemishes before the finishing touches are added.
Sanding walls or before painting will help eliminate any imperfections such as scratches, gouges, and other flaws which may become very prominent after painting. There are times when many of these imperfections are difficult to see before painting that become very easy to see after. Painting is one of the best and most rewarding DIY projects you’ll come across, and the one thing that makes it all worth it when it’s all said and done.
To make sure you save time during and get the perfect look your hoping for with your next DIY project, the following information on what is the best grit sandpaper before and after painting drywall and wood will do just that.
Recommended Grit Sandpaper Before Painting Walls
Before painting, there has to be a happy median between coarse and fine sandpaper. While coarser paper will save you a great deal of time while knocking down raised such a joint compound, it will also cause you more work getting rid of scratches.
For drywall, we recommend starting with a 120 or 150 grit sandpaper before finishing up with 180 and 220 before painting walls. Drywall compound is quite soft and when using coarser grit paper such as 80 and 100 you may end up leaving blemishes which will cause you more time effort.
For sanding walls to remove old paint, you may want to start with 100 grit sandpaper and move in the same upward progression from coarse to fine before ending at 220 paper. You’ll definitely want to be careful not to exert too much pressure on the sander. Remember, always allow the mechanical work of the sander to do all of the work and not your own physical pressure.
Recommended Grit Sandpaper Before Painting Wood
When sanding wood, it’s recommended to be a bit more methodical approach of starting at 100 grit sandpaper and progress upwards. Many people tend to skip a grit of paper looking to save a bit of time, but believe me when we say this, this isn’t a good idea. Getting the optical finished look whether it be with wood or drywall, skipping one grit to save time may make it difficult to eliminate all blemishes.
Recommended Grit Sandpaper After Painting Walls
There will be times when you have to touch up minor areas of the wall after painting such as paint that dripped. You can simply use a razor blade to remove the unwanted paint, add primer to the area, and re-sand before painting.
Wrapping it all up, using a sanding block and 220 grit sandpaper after painting walls will help restore that smooth finish you were looking for giving you the opportunity to prime and repaint.
