Technical Data Sheet
P79-Aufbrennsperre
Primer beneath render
Art.-No. 2 05402
Properties: • Concentrate • Non film forming • Hydrophobic • For rendering at short notice • For interior use
Product application: Dilute P79-Aufbrennsperre with clean water in accordance with the instructions mentioned and applied by brush or spray dependent on the absorbency of the substrate to be rendered. Render is applied once the render primer has fully fried out.
Areas of application: P79-Aufbrennsperre is applied to absorbent substrates requiring rendering such as brickwork, lime-sand blockwork and aerated concrete blockwork in order to prevent subsequent renders from drying over quickly or from lacking in water for hydration.
Important advice: • Before use, a site trial is necessary if it is not possible to determine the substrate requirements exactly. • The primer must be dry before render is applied. • Do not work wet in wet. (Render: 1 – 3 days after application of P79-Aufbrennsperre). • Protect areas not being treated from P79-Aufbrennsperre. • Wash off splashes immediately. • Glass, metals, clinker, window frames etc may become etched by P79-Aufbrennsperre. • Avoid contact with the eyes and skin. • Keep out of reach of children.
