Pictured is our 17-year-old synthetic blue stone front porch. Every other year, I clean out and carefully refill any gaps between the stones (be sure to follow directions on the polymeric sand package and let that sand fully harden). In the past I always applied the Black Diamond Wet Look Sealer via roller and brushed it out or used a garden pump sprayer and brushed out it. Both worked well, but it required a lot of time to brush out the material that pooled in the uneven areas of the stone. This year I bought this brush. WOW! I was able to give the deck 3 coats (be sure to allow recommended drying time for the sealer) in the time it took to apply just one coat in the past. Excellent product in terms of quality of construction, brush flexibility, and brush durability. Because it can be screwed onto an extension pole, no need for kneeling at any time. Cleaning up the brush with a hose sprayer is a breeze. Highly recommend this product.Got these to stain my deck, it makes staining just fly by so quuck! You can cover a large area and quick too especially with a handle!I normally used a roller to stain decks, but my first time using the 7 in and very glad to give two costs in less time that I expectedEasy to cleanWorked out great painting my deck ??.I love it so soft and love using it on my canvas artPerhaps I shouldn't say it really works great, since you're the one doing the work. However it really did make things much easier and faster with a super light tip on the brushes it just did a super super job on the deck that we were sealing. The extra wide brush made work so much easier and even the extension screwed on to a handle we have laying around the super easy job did 500 ft deck in under 2 hoursThese things attached to a pole and work much better than a roller. I have a huge deck and this is a lifesaver. I will never stay in a deck without these again.Paints like a dream
