P79-Aufbrennsperre
Building SCHOMBURG Product Systems
Technical Data Sheet Art.-No. 2 05402
Primer for finish Properties: P79-Aufbrennsperre prevents the serious dry out of plaster on highly absorptive surfaces like brick masonry, lime sandstone, expanded concrete. P79-Aufbrennsperre forms no film and does not cause a parting layer between plaster and masonry. P79 does not reduce the vapour diffusionability of the masonry. P79-Aufbrennsperre disposes of hydrophobizing attributes and results a slight water repellence to the surface. It does not cause a complete water-proofing.. Water that the plaster needs to cure is not removed on surfaces pre-treated with P79. Areas of application: P79-Aufbrennsperre is applied on absorptive surfaces which are to be finished like brickwork, lime sandstone, expanded concrete to avoid the fast dry out of the plaster.
