Description

BAL Prime APD Acrylic Primer is a rapid-drying, coloured, acrylic primer for preparing wall and floor backgrounds prior to fixing of ceramic, mosaics and natural stone tiles in dry or wet internal and external environments.

BAL Prime APD may also be used with BAL Acrybase, BAL Level Max Levelling Compounds and with BAL WP1 waterproof coating for walls and floors. It also isolates products containing calcium sulphate such as gypsum plaster and anhydrite screeds from cement-based adhesives.

Features green/blue colouring to help ensure that a complete and even coating is obtained. Available in 2.5 litre containers. 15-30 minutes drying time (at 20°c).

Coverage: Undiluted: 100-200ml/m², Diluted (1:1): 50-100ml/m²

BAL Prime APD Acrylic Primer provides surface strength to friable surfaces and reduces the porosity of porous backgrounds/bases, preventing the formation of air bubbles and prolonging the flow time with levelling compounds. Also can be used for extending the open time of BAL Ready mixed wall tile adhesives.

BAL Prime APD Acrylic Primer can be used on the following substrates: Brick/Concrete, Rendering, Lightweight Blockwork (must be rendered), Cement:Sand Screed, Plaster, Plasterboard, Tile Backer/Fibre Cement Boards, Tongue & Groove Floorboards, Overlaid Timber Floors (15mm minimum), and Anhydrite/Calcium Sulphate Screeds.
