AG 703 Stained capping primer for absorbing substrates

For reduction and optimization of substrate absorption. Particularly recommended before flooring (underlay, self-levelling and flow-applied), levelling substrates, gluing tiles with cement-based adhesives on demanding substrates (e.g. made of silicate elements, cellular concrete, gypsum blocks, on gypsum plaster, gypsum and anhydrite screeds, fibre cement/gypsum boards, etc.).
