We recommend that you use a brush during painting when decorative plasters and textured masonry surfaces...
#FastTipTuesday - The mark of a good brush!
Using a quality brush when painting is all part and parcel of creating the perfect finish and adds a professional touch.
When using cheap paintbrushes, the paint coating will be to thin and you'll struggle to achieve the required hiding ability while applying the paint.
Take care of your paintbrush and make sure you clean it well when you're finished. Store it by hanging it up on a hook - this will prevent the bristles from forming a "fan" which makes it very difficult to paint perfect stripes when this happens.
