SPARTYTE MAR-col
MINERAL FORMULATION FOR THE PATCH REPAIR OF LIMESTONES AND MARBLE
Description SPARTYTE MAR-col are formulations that are composed out of mineral inorganic
components, which after mixing with water can be used for patch repair of almost every type of lime-stones and marble. The product is available in different versions, depending on the type of application or colour. The different types are distinguished by a final code or number Advantages  Good mechanical and physical properties, colourfast also in severe climatic
 The consistency of the product guarantees a perfect patch repair even for difficult and  The product can also be formulated towards a piece of stone from the jobsite, after analyses by our laboratory of both the pigmentation and the physical-mechanical properties of the existing stones  SPARTYTE MAR-col contains always some limestone and marble pieces( of which the origin and density differ in function of a wide range of esthetical and structural finishing) in an optimal granulometric distribution.  The structural hardening is based on the hydratation of carbonates and mono-silicates  Volumetric stability can be obtained in function of particular demands. Several levels of volumetric compensation are available depending on the request of the customers. Field of Everywhere a reliable local repair of limestone or marble is needed. The product can be
application applied in several layers or as a cast repair depending on the job.
Use  Recommended to apply with the aid of a rubber mould. The counter-form can be made
of gypsum or a more rigid material. In case of emergency it can be made of inox or a more common material.  Avoid a gypsum form if the surface is not completely closed and there is a possibility for water-absorption of the product with the contact surface. The applied product will, in case of water loss by absorption, be compromised in strengths.  Mix with the water until the desired consistency is obtained. First mix with 10% water referring to the weight for 1-2 minutes and then add water while mixing for about 4 minutes, until the mix is lumpfree.  Keep the application wetted for at least 2-3 days after the demoulding.  For optimal protection and aesthetics together with a better conservation of the repaired surface and to reduce dirt or smog pick-up on the surface, the application should be protected with impermeabilizzante WP-55/LP.If desired a protective surface consolidation can be done with TECNOSOLID-82 as a second treatment (first test if there is no discolouration of the surface). In the case a better colour uniformity or better aesthetics with the existing part of the structure is desired, apply VELART, a transparent, protective coating, .This can be formulated “ad hoc” in different shades of colour.
