The roller to be used is made of polyamide (floor rollers for example).
It is advisable to apply to two minimum coats, with performance of 3 m²/kg, waiting time between coats of 2 hours minimum and sanded at 24 hours with medium grain sanding (grain 150-220).
’For finishing on Montoplac preparation:
For high quality paints, use fixing emulsion (Emulsión Fijadora) or Fijamont as a primer and apply 2 coats of paint, using putty between coats to fill in any defects.
For standard paints, use diluted product as a primer, then putty to fill in any defects and finish with a second coat.

Cement/plaster putty:
Check that the putty is suitable for the substrate.
Wait until it has completely set (30 days minimum) Clean the substrate to remove any efflorescence and to neutralise alkaline surfaces.
Sand polished surfaces to make them more porous.
Clean the substrate to remove foreign substances and/or residues.
Open up any cracks or fissures to thoroughly clean them, remove dust that is produced using a brush, and then plaster themFor extremely thin surfaces, before applying putty, use an appropriate fixative (see family 6): Emulsión Fijadora, Fijamont, Fijalite.
