GROVE® RASANTE

Anti-Carbonation Concrete Levelling Compound

Description

GROVE RASANTE is an anti-carbonation levelling compound for concrete based on cement, selected aggregates and special additives for the ideal finishing treatment of surfaces previously restored with GROVE RIPRISTINO or GROVE RAPIDO and for the protection of concrete surfaces.

It can form layers with thicknesses ranging from 1 to 10 mm.

GROVE RASANTE meets the requirements defined in ENV 1504-9 ("Products and systems for the protection and repair of concrete structures: Definitions, requirements, quality control and evaluation of conformity. General principles for the use of products and systems") and the requirements of the European standard EN 1504-3 ("Structural and non-structural Repair") for class R2 mortars.

Usage field

GROVE RASANTE can be used:

  • for finishing concrete surfaces during degraded concrete restoration works;
  • to smoothen up cast-on-site concrete and prepare it for a final paint or resin finish.
Packaging

25 kg bag in 48 bags pallets.

Application

Preparing the Substrate

  • thoroughly clean and remove all loose particles;
  • thoroughly wet the laying surfaces and avoid applying the product on varnished or painted parts, plaster, wallboard and plastic coverings.

Preparing the Mixture

  • Mix the contents of a GROVE RASANTE bag with about 5.5 litres of clean water with a slow-rotating drilling machine for solid materials (anchor impeller), until a mixture free of lumps is obtained.
  • Generously wet all laying surfaces and apply the product to the surface after restoring it with CEM-OX and GROVE RIPRISTINO or GROVE RAPIDO.
  • To make the coves and to realize iron covers over the spacers, thoroughly wet the substrate and proceed with the direct application of the product.

Applying the Product

  • Apply to the surface to be treated in successive coats, each coat being not thicker than 5 mm, with a steel trowel or plaster, until obtaining the desired thickness which, however, should not be thicker than approx. 10 mm in two coats.

Product Finishing

  • As soon as the levelling compound begins to set, do the smoothing with a sponge float.

Curing the Product

  • Particular care must be given to the product curing phase, because during the warm months, it must be repeatedly wetted in the first 48 hours.
Tool cleaning

Clean tools and equipment with water while the product is still fresh, if it has hardened remove it by mechanical means.
