Review on Wooster Brush Company RR929 9 Roller by Fernando Hudson

We have decorative tamped concrete around the pool with relatively large elevation changes. It's been 4 years since it was installed and it clearly needed resealing. I took a pack of these to apply sealant to a flat surface. They had excellent absorbency; Anyway, I had to be careful not to get too much sealant. The pile size was almost perfect for penetrating the grooves and I feel like I got even coverage across the entire face of the pool. We also used a solvent based sealer which others have reported as being quite harsh for brushing and rollers and these types have held up quite well. I replaced the first one after about 2 hours and 200 square feet, which was more than I needed. Next time we re-caulk the pool I'll definitely take another bag of these with me.
