Brush paint on and then roll with this to smooth. Sand between coats. It is the best roller. As close to a spray as you will get. ### ⭐⭐⭐⭐⭐ Will fit the Purdey roller frame too. *by P***N on 29 June 2026* Bought these as they also fit the Purdey mini roller frame. Purdey don’t manufacture foam roller heads so these are a great option that will fit both Wooster and Purdey frames. ## Frequently Bought Together - Wooster Brush RR308-4-1/2 Pro Foam, 2-Pack, 4-1/2-Inch - Wooster Brush RR028 Jumbo-Koter Shergrip Roller - Wooster Brush RR304-4-1/2 Jumbo-Koter Mohair Blend Roller 1/4-Inch Nap, 2 Pack, 4-1/2-Inch --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/285769699-wooster-brush-rr308-4-1-2-jumbo-koter-pro-foam](https://www.desertcart.us/products/285769699-wooster-brush-rr308-4-1-2-jumbo-koter-pro-foam) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-16*
