RASANTE B1 is a monocomponent premixed mortar, in transpiring powder, to employ as filler skim coat also for high thickness (up to 10 mm per coat), on concrete surfaces, internal and external plasters, composed of hydraulic binders, selected sands in various granulometries, synthetic binders, various admixtures.
RASANTE B1 is suitable for the following applications:
- surfaces regularization of concrete’s castings or precast panels which present imperfections, porosity, eroded or damaged areas
- surfaces regularization of traditional plasters
- to bury the fibre glass mesh
- levelling of brickwork or brick-cement surfaces
- ideal for high thickness repairs
- excellent for both ceiling/wall application
Before the product application it is suggested to remove all the damaged or crumbly parts, until you have a surface good and resistant, then clean the surface removing dust, oil, grease traces etc.
Mix one sack of kg 25 RASANTE B1 with lt 4-5 of clean water with mixer or helix put in the drill at low speed until you obtain a homogeneous lump free paste. Let stand the mixture and shake it again briefly before the use.
Apply the mixture on surface with metal trowel in a uniform thickness, if necessary bury the primed fibre glass mesh pressing it with smooth trowel on the fresh mixture layer. You will obtain this way a layer compacted and regular; apply a second coat finishing again with smooth trowel, or in alternative, with sponge trowel already damp after some minutes from the application.
In hot periods it is suggested to damp the substrate and the product applied after 24 hours, before the coloured finishing application make sure that the product is adequately cured.
