Abstract

A renovation method and renovation coating to renovate walls or floors that include a plastic surface ( 130 ) that are in need of renovation and are provided with a coating. Several pre-shaped renovation coatings ( 150.1, . . . , 150.4 ) whose inner sides match the contour of the plastic surface ( 3 ) to be renovated are placed onto the surface and secured to it using adhesive, whereby their inner layer is formed of a hard foam and possesses at least one outer layer consisting of reinforced mortar. An additional covering layer is bound with the mortar layer.

1 . In a method for renovating seats, recliners, walls, or floors with plastic surfaces in need of renovation and that may be provided with a coating, 
 the improvement wherein    at least one shaped hard-foam sandwich element is shaped with its inner side matching the contour of the plastic surface to be renovated is applied to this plastic surface and secured by means of adhesive, and wherein the inner layer of the shaped hard-foam sandwich element is formed of a hard foam and possesses at least one outer layer consisting of reinforced mortar which in turn is attached to an additional covering layer.    
   
   
       2 . Method as in  claim 1 , wherein the surface to be renovated is part of a pool, particularly a swimming pool.  
   
   
       3 . Method as in  claim 2 , wherein the renovation coating intended as a coating to renovate a pool is several hard-foam sandwich elements ( 150 . 1 , . . . ,  150 . 4 ) bound or joined together.  
   
   
       4 . Method as in  claim 1 , wherein the renovation coating intended for a seat or a recliner is several hard-foam sandwich elements bound or joined together.  
   
   
       5 . Method as in  claim 1 , wherein the inner side of the hard-foam sandwich element coming in contact with the plastic surface requiring renovation is provided with a reinforced mortar layer.  
   
   
       6 . Method as in  claim 1 , wherein the hard-foam sandwich element is at least partially covered on its outer layer with ceramic covering elements, particularly mosaic tiles.  
   
   
       7 . Method as in  claim 1 , wherein the hard-foam sandwich element includes a varying profile thickness over its entire surface.  
   
   
       8 . A renovation coating for performing the method as in  claim 1 , wherein the coating is a hard-foam sandwich element whose inner side matches the contour of the plastic surface to be renovated as an individual element or as fitting tiles, and which is coated on its outer surface with a mortar layer.  
   
   
       9 . Renovation coating as in  claim 8 , wherein outer surface of the hard-foam sandwich element bears a plastic layer suitable for a seating surface that is integrated with the mortar layer.  
   
   
       10 . Renovation coating as in  claim 8  wherein the thickness of the sandwich elements is between 10 to 50 mm.  
   
   
       11 . Renovation coating as in  claim 8 , wherein outer surface of the hard-foam sandwich element bears a plastic layer suitable for a seating surface that is mounted onto a mortar layer.  
   
   
       12 . Renovation coating as in  claim 8 , wherein outer surface of the hard-foam sandwich element bears a plastic layer suitable for a seating surface that bears a layer of wood material.
