Polyamide Paint Roller Cover

I wanted to post this because of all the discussion of the rope materials we use. I thought it was interesting how those fibers enhance other trades like painting

Growing up in a family painting biz, I've been slapping paint for over 40 years and have used many different roller covers over the years. The worst part of rolling is cleaning the roller cover when done. With latex paint, it seems to take forever, and a lot of water to get all the paint out. No matter what cleaning technique you use, you always seem to have that last little minute trace of paint clouding up your clean water and it just never ends. Using paints like Kilz 2 that dry fast perturbs the problem and additionally leaves the roller nap with little "crusties" that stay in the roller fibers.

Yesterday, I bought a new 1" nap roller cover made with polyamide fabric, not polyester or wool. I used this roller with 2 different types of stain blocking primer. I will attest that this was the easiest to clean roller cover I've ever used. The paint released quickly and I had crystal clear clean water in no time with no more than simple rinsing under under a bath faucet. Additionally, there were no crusties and the fibers looked brand new when done. I'm blown away.

Whe they say polyamide, I have no idea whether they're saying its natural (like wool), or nylon, or one of the aramids. But, based on the way paint releases from the fibers when cleaning, I would almost venture that its an aramid, i.e. "slick" fibers. To add to that, I noticed a lot of little colored strands in the tub - that don't normally see - that I thought were roller fibers. After analyzing, I determined they were actually hardened paint particles, which I believe were the "crusties" that normally remain in the roller. They market these covers as "high release", so maybe it is indeed aramid. Anyway, I love 'em.

Nylon is a polyamide. Nylon absorbs more than polyester, maybe why it wasn’t used in the past? They might have found a way to prevent the absorbing.

Yeah but does the nap lay over nicely like a good Wooster wool cover? ;)
