BIOSISTEM SPRAY for interior and exterior walls.It can be applied on any wall surface. It can be also applied on existing paints and plastic coatings.

New sufaces or previosly painted with waterborne paint. 
Treat the surface with 23410200 Biosistem Spray, from a distance of 10 - 15 cm.Wait for the surface to absorb the product for 2 - 3 hours, then clean the treated surface with water. If the result obtained is partial, repeat the operation. After 24 hours from the application, brush the surfaces if necessary.For a better preventive action, treat the surface with 23410230 Biosistem Titansan;in this case wait at least 24 hours after the application of 23410200 Biosistem Spray. Apply 23410230 Biosistem Titansan exclusively with a roller or brush, leave to act for 24 - 48 hours, keeping the rooms ventilated. The treatment can be repeated several times for a better penetration into the surface and therefore for best effectiveness. Complete the painting cycle with 23400250 Fissativo Biosistem fixative (if needed) and with one of the waterborne paints of the Biosistem Line. Old tempera or lime-based paint must be removed completely.
We recommend using a brush for an optimal application, because it ensures the maximum penetration into the surface.Brushes and application tools can be cleaned easily if washed straight away with water. Any hardened drips can be easily removed with Diluente Nitro 92100012 thinner.

9-11 sq.m/l for each coat, depending on the absorbency of the surface.
