Ready-to-use, colourless pre-treatment primer based on a synthetic resin dispersion. Should be applied to highly absorbent substrates such as new stucco or plasterwork before applying a decorative plaster. Good film-forming properties, odour-free and quick drying. If smooth plasterwork is painted with wall paint, the substrate must be pre-treated with SPS Fixator stabilising primer. For interior use in dry rooms.
