I always preferred the 3M sponges to the webb.... seems to eat threw the spackle and bondo way better with just 2-3 swipes.... maybe I'm buying the wrong grit webb but they are the only ones I see. The webbs are defiantly a lot softer than the 3M's and seem to loose their effectiveness faster, at least from my experience.
Hello, I'm an account manager for Webb Abrasives and saw a good chunk of sample requests come through our site recently referring to a thread on painttalk so I had to stop by and check it out.
Just wanted to comment on what Romanski said - you must not be using the right product or right grit, because there's no way that we could lose our effectiveness faster than the 3M sponge.
99% of the sanding sponges out there use what is called a Nitral adhesive that holds the grit on the sponge - Nitral adhesive tends to become brittle and ridgid under cold conditions and gummy and melt in heat. The actual melting point for this adhesive is 176 degrees Fahrenheit, but at 120 degrees it actually begins to sublime, and become gummy - at that point the grit buries itself into the adhesive, rendering the sponge useless. You can create a temp of 120 degrees through the friction of using the sponge on bare wood with minimal effort. Basically, most sanding sponges are designed to fail.
Our sponge uses a special "adhesive" that really isn't an adhesive at all (I honestly can't tell you what it is), but this stuff does not begin to sublime -and fail - until a temperature of 320 degrees
. Also not effected by cold/heat. Our sponges last at least twice as long as any other sponge, period, end of sentence.
So just wanted to add that to the mix here, Romanski. I'd like to send you some samples, I'll send you a variety of grits and styles to try, because if we're failing faster than the 3F product then something just aint right... Sounds like you're using the wrong product. I'd like to send you the right product.
