Can I use steel wool instead of sandpaper?
Steel wool can be used instead of fine sandpaper for many sanding jobs. The very fine strands of steel gently cut into the surface being sanded, removing an ultra-thin layer. The finer grades are particularly useful for the delicate work of sanding between finishes (cutting back).
Is an orbital sander better than a palm sander?
Orbitals are heavy duty tools, whereas Palm Sanders are smaller and more lightweight. Orbitals are better for working on large pieces, whereas Palm Sanders is best for small pieces. Orbitals will get bigger sanding jobs done much more quickly, whereas Palm Sanders gives a much smoother result.
Can you apply a second coat of polyurethane without sanding?
There is no substitute for sanding between each coat if you want the best finish. I get the best result building or refinishing furniture when I thin oil based urethane 3 parts urethane- 1 part mineral spirits for the first coat. Sand with 220 grit after first coat and wipe down with a tack cloth.
Which is better orbital or belt sander?

What is the difference between aluminum oxide and zirconium oxide?
White aluminium oxide is the most pure, it is also the toughest and most hard wearing. White aluminium oxide cuts well in hard wearing metal working applications and is used in products such as our JF4top material. Although zirconia is tougher than aluminium oxide it will struggle to effectively grind mill scale.
Do you have to sand between coats of Polycrylic?
