Abrasive Selection: Experience to Extremes

Written by on August 28, 2011 in Abrasives, Industry News, Sanding and Dust Collection with 1 Comment

The most effective measure of an abrasive technology is how the wood takes finish. On paint grade, it’s more about adhesion, while on stain grade its that but with a deeper visual aesthetic. The abrasive can’t take all of the credit. The dust extraction system is exerting significant influence in the rich, crisp look of the finish by preventing fine dust from being pushed into the grain. In stain grade wood preparation it is especially critical to use abrasives that do not clump and scratch during finish sanding. These tables were stripped at 80 grit and walked through each grit to 150, then block sanded out to 240 prior to stain application.

 

These photos are a small glimpse into the broad variety of tasks that the tools, abrasives and dust extractors are put through during a testing phase for review by us. We don’t do much with stock photos and manufacturer specs, it’s hands on or nothing, and we show tools and products in the most extreme circumstances possible because that is often what pro paint projects call for. Solutions to real problems. For a couple of junk pieces of furniture, the combination of tools and finishes brings them back to life in short order. Not bad for some shop based exploration. More rigorous applications are taking place out in the field on exterior wood restoration tasks. Lets hope Irene passes quickly so we can get back out there.

Meanwhile, if you have any ideas of unusual circumstances we can continue to expose products to in the interest of demonstrating extremes, we are all ears. We’ve already taken one recent forum generated request and put it on the schedule as a field based test. Fun stuff.
