Material for coating waterpproofing surfaces and method of coating waterproofing surfaces

Abstract

A material for coating waterproofing surfaces, including a first support layer made of synthetic and/or textile material and a second layer including a modified acrylic resin with high reflectance properties coating the support layer.

1 . A material for coating waterproofing surfaces, comprising a first support layer made of synthetic and/or textile material, a second layer comprising a modified acrylic resin with high reflectance properties and a further layer consisting of an adhesive superimposed on the face of the support layer opposite to the face coated with the layer of resin. 
     
     
         2 . The material according to  claim 1 , wherein a film of plastic material or polyethylene or polypropylene is provided between first support layer and adhesive layer in order to prevent migration of the bituminous mixture towards support layer, once the coating material has been applied. 
     
     
         3 . The material according to  claim 2 , wherein the acrylic resin, of which the second layer is made, is added with substances selected from the group of: coloured pigments, quartz, vitreous material, antiflame substances, antismog substances with photocatalytic properties. 
     
     
         4 . The material according to  claim 3 , wherein a layer with dimensional stabilization properties is interposed between the first support layer and the second layer of resin. 
     
     
         5 . The material according to  claim 3 , wherein a layer with dimensional stabilization properties is incorporated in the second layer. 
     
     
         6 . The material according to  claim 5 , wherein said layer with dimensional stabilization properties comprises a net of glass textile, polyester (PET), polypropylene (PP). 
     
     
         7 . The material according to  claim 6 , wherein said further layer of adhesive is of the type used for recovering or repairing waterproofing membranes. 
     
     
         8 . The material according to  claim 7 , wherein said layer of adhesive is protected by a layer of siliconed film. 
     
     
         9 . The material according to  claim 8 , wherein the acrylic resin includes an aqueous dispersion of inorganic charges, dioxide, calcium carbonate, talc, hollow glass microspheres in an acrylic styrene resin. 
     
     
         10 . The material according to  claim 9 , wherein the acrylic resin further includes a dispersion of acrylic copolymer to which wetting and levelling waxes are added. 
     
     
         11 . A method of coating waterproofing surfaces, comprising the steps of:
 providing a first support layer of synthetic and/or textile material;   providing, on said first layer, a second layer comprising a modified acrylic resin with high reflectance properties, thereby obtaining a composite layered material;   providing a layer of adhesive on the face of said first layer opposite to the face coated with the second layer;   coating a waterproofing surface by means of said composite material thus obtained, by causing a face of said first support layer to adhere to the exposed face of the waterproofing material.   
     
     
         12 . The method of coating waterproofing surfaces according to  claim 11 , further comprising the step of:
 providing a film of plastic material or polyethylene or polypropylene between first support layer and adhesive layer in order to prevent migration of the bituminous mixture towards layer, once the coating material has been applied.   
     
     
         13 . The method of coating waterproofing surfaces according to  claim 12 , further comprising the step of:
 providing a layer of material with dimensional stabilization properties between said first layer and said second layer.   
     
     
         14 . The method of coating waterproofing surfaces according to  claim 12 , further comprising the step of:
 incorporating a layer with dimensional stabilization properties in the second layer.   
     
     
         15 . The method of coating waterproofing surfaces according to  claim 14 , further comprising the step of:
 providing a layer of siliconed film for protecting the layer of adhesive.
