Alderson Portable Sanders

The Alderson® sanding machines have been designed to be used in conjunction with water. It is the water that significantly reduces the frictional heat build-up that damages the paint substrate which is often invisible after sanding – especially when sanding water based painted surfaces. The damage results in blisters forming under the substrate paint and these blisters often don’t become obvious until the surface has been repainted. The use of water virtually eliminates clogging. Clogged paper also contributes to heat build-up. So these machines extend the life of their abrasive paper and significantly reduce the time it takes to prepare a surface for painting. The machines can also be used in wet conditions and it also eliminates the need for pre-sanding preparation such as water blasting and wiping the surface dry before dry sanding.
