Application

Used for levelling and smoothing over surface irregularities on wall and ceiling backgrounds such as concrete, brickwork, blockwork and previously applied cement/ sand renders prior to applying paints and other cement-resistant decorative coatings. It is suitable for internal and external use and is an ideal solution for areas subject to moisture such as swimming pool halls and underground tunnels. Low strength backgrounds such as lime/ sand renders are not suitable surfaces to apply ARDEX A125.
