ASO-Unigrund-S reduces the porosity of the <br />substrate and protects moisture sensitive substrates from <br />the water in cement-based adhesives. Suitable for use on <br />existing tiled finishes, hydraulically setting cement, cementlime renders and gypsum plasters, gypsum fibre boards,</p> <p>Ready for tiling: on non-absorbent substrates after <br />complete through drying <br />(approx. 1 hour at +15° C), on <br />absorbent substrates as soon as the <br />ASO-Unigrund-S surface is dry</p> <p>1/2</p> <p>05/18</p> <p>Product application: <br />Stir thoroughly before use. Evenly apply a thin coat of <br />ASO-Unigrund-S at right angles with a foam or lamb’s <br />wool roller. Use neat on non-absorbent substrates, on <br />absorbent substrates dilute 1:1 with water. On nonporous substrates further processes may only be carried <br />out once completely dry. Drying time approx. 1 hour. <br />On absorbent substrates tiles can be laid as soon as the <br />ASO-Unigrund-S is surface dry – approx. 5 minutes – and <br />touch-dry. The dry coating is transparent-pink and sand <br />grey. When using externally, protect ASO-Unigrund-S <br />with a bonded waterproofing system for use beneath tiled <br />finishes e.g. AQUAFIN-2K/M.</p> <p>Cleaning agents: water, remove dried on material <br />with ASO-R001 <br />Storage: Frost free, min. 12 months in the <br />original unopened container. Use <br />opened packaging promptly. <br />Consumption: approx. 50 to 100 g/m2 dependent <br />on the porosity of the substrate <br />(Note: Technical application trials <br />have shown that the consumption is <br />220 g/m2 when used on old tiled <br />finishes.) <br />Substrate preparation: <br />The substrate must be dry, load-bearing, adequately flat, <br />free from penetrating cracks and free from separating <br />substances such as oil, paint, laitance and loose <br />components. Abrade calcium sulphate screeds, vacuum <br />followed by priming with ASO-Unigrund-S. Substrates <br />must be dry, sound and free from contamination, dust and <br />separating agents. Remove weak or adhesion impairing <br />layers e.g. old adhesive, smoothing compounds or <br />paint residues by e.g. mechanically brushing, abrading, <br />scabbling or shot blasting.</p> <p>Advice: <br />• When applying ASO-Unigrund-S protect areas not to <br />be treated. <br />• Wash off splashes immediately with water. <br />GISCODE: D1</p> <p>The moisture content for ceramic tiling, when measured by <br />a carbide hygrometer (CM device), must not exceed: <br />• Cement-based screed 2.0 CM% for screeds on <br />insulation or separating layers in interior areas. <br />• Calcium sulphate screeds without underfloor <br />heating 0.5 CM%. <br />• Calcium sulphate screeds with underfloor <br />heating 0.3 CM%. <br />• Gypsum based plaster 1.0 CM%.</p> <p>Information about the emission level of volatile compounds in indoor <br />air, which pose a health risk by inhalation, on a scale from class A+ <br />(very low emissions) to C (high emissions).</p> <p>This technical data sheet does not consider local building codes or legal requirements.
