This will answer all these questions and give you all the info you will need as a beginner DIYer.
A quick guide to sand paper, the simple things which will help you buy the right stuff for the job!!
1) Sand Paper has a grit number (how coarse it is)
- Low numbers more coarse
- High numbers less coarse
2) Always start with the low numbers and work up to get the smoothest of finishes!
40 - 50 Use this for rough shaping of wood, removing previous finishes
60 - 100 For final shaping and removing of light marks from the wood
120 - 220 These are for the final finishing.
240 - 400 Used between coats of varnishing or spray for a super fine finish
3) Don't worry you don't need to buy every type! For the projects I share I tend to use P40 - P80, P120, P240 (You don't really need to know what the P means but this is how you'll see it in the DIY Shop!)
So there are also different options of sanding tools, do I buy just the sand paper, a sanding block or a electric sander?
The answer is it really depends on the project! But I will share with you the basics for some common projects you may be doing!
Sand Paper - I often just use the sand paper on its own if I need a small area sanding but this isn't ideal and results will be inconsistent If you're sanding a large area!
Hand Sander - These are great for sanding walls, seams etc, just attach your sand paper to the block and off you go!
Sanding Block - Great for smoothing wooden surfaces, such as a book case or if you're having a go at the Lollipop Cabinet!
Mouse Sander - This is what you will see me using fairly often, I use it for a variety of things, upcycling furniture, removal of old paint, getting into tight corners (the best of the electric sanding tools for this! - You can use a whole range of sand paper grits for this a good allrounder for smaller projects!
Belt Sander - If you are trying to remove layers of paint or varnish this is the tool for you! Will make the job way more bearable! - They're not the cheapest so if it is only for 1 or 2 projects look at renting!
That's it a 2 minute read and you're a sand paper pro!
