MULTIGRANIT 500 ml protection for granite

Characteristics

MULTIGRANIT is a non-filming sealer/impregnator that, as all the range of the GENERAL sealers, has high characteristics of permeability to the vapour and bars the penetration of the liquids, both of oily and aqueous nature, without any change of the natural appearance of the treated materials.

CHEMICAL NATURE

The molecules used are well known for their oil and water repellent characteristics. The innovative aspect of MULTIGRANIT consists in fixing these atoms chemically to polymers of silicon nature which, besides increasing the water-repellent effect, also fasten with strong chemical bindings onto mineral substrates of siliceous nature (this includes all kind of granites).To ensure a high degree of penetration, and so a protecting impregnation, on microporous substrates (like the polished granites) our laboratories succeeded in insulating and building up a polymer of very small size in which oil repellent and water repellent molecules are together. The achieved result shows clearly the superiority of MULTIGRANIT if compared to the protecting sealers since long time in the market.

PREPARING THE MATERIAL TO BE TREATED

The product is absorbed by capillarity and the substrate to be protected must be porous and absorbent and perfectly clean and dry (and specially in case of outdoor application the material must be perfectly dry to avoid eventual bleaching on the surface). The low viscosity of the product and the high capacity of the solvent used to “wet” the substrate make it possible to obtain a good impregnation in depth. When the solvent evaporates, the active solid part chemically fastens onto the substrate and covers the capillary walls of the granite exposing outwards the oil/water-repellent atoms performing the protective action.

HOW TO APPLY

(THIS IS THE MOST DELICATE AND IMPORTANT PHASE OF THE PROTECTION PROCESS)

The absorption process is not immediate but requires time; the protective liquid must therefore remain in contact with the granite and wet it for at least 5-10 minutes. During this phase the air inside the pores of the material is replaced by the protective liquid and comes out in the form of bubbles. The product has to be spread homogeneously to form a even layer wetting all the surface and it can be applied by a cotton cloth (not losing hairs) or by other suitable means (paint-brush, low pressure sprayer, etc.) 30-40 minutes after the application the excess of product not absorbed must be removed to avoid, because of drying and fastening on the surface, the appearance of the granite is changed by this excess or it is difficult to remove it. To achieve the optimal result of the protection treatment, it is suggested to affect a double application in fast sequence.

LIFE OF THE TREATMENT

The effectiveness of a properly done treatment with MULTIGRANIT has no limits of time that can be predeterminated. It is logic that a strong mechanical wear on the surface or/and the repeated action of detergents can make appropriate a recurring application.
