About this deal
When I compare it to my dedicated B&D sander with the same platen profile, I have never had any melting issues and I worked the B&D as hard as the DeWalt and over many years. On the second night of sanding, when I went to replace a sanding sheet, I found that I had melted one corner of the platen which I cursed myself for doing (this melted off the Velcro surface), thinking I had been too hard and aggressive when sanding. So my only conclusion is the platens' are not high grade material, despite having the DeWalt brand.
So my advice for using the sander is - don't use it for corner or edge detailed work when the pressure is all on the front point of the platen. Read full review I bought a new DeWalt multi-tool mainly for cutting floorboards and into dry wall for boxes, but it came with a sanding head and I thought that was great. Because the DeWalt has a powerful motor the sanding platen fitted with rough grade paper really got through most of what I was using it for. But then I started doing door frames and therefore had to put a lot of effort into the hard-to-get corners.
