Package includes replacement foam roller covers for use on a mini-roller frame. High Density Foam provides an ultra smooth finish with minimal stippling and bubbling. Foam rollers are especially absorbent, which translates to taking in a larger volume of paint than a traditional roller making them well suited to large surface areas. Another benefit to absorbing liquids easily is that when the outer surface of the foam is smooth, it redistributes that same liquid evenly. Because these rollers offer high-density foam they are extremely useful on smooth surfaces where the roller can glide along and dispense paint such as on doors, cupboards, shelves, jambs, window frames, furniture and more. Designed for use with water or oil based stains, enamels, varnishes and urethanes. Ideal for smooth surfaces and where a brush is not enough and a full size roller is too much.
