Abstract

An alternative is presented to today's practice in construction of applying a thin layer of plaster to plasterboard or “blueboard”. In this invention, the inside or exposed surface of plasterboard or its equivalent is pre-coated with a relatively thin layer of plaster under controlled conditions at a remote location, such as a factory or other facility near or at the construction site, before the plasterboard is placed on the framing of the structure. The coating can then be cured under controlled conditions before the boards are installed on studs with fasteners, or adhesives. The seams between the boards may then be patched.

Claims

exact text as granted — not AI-modified
1 - A method for improving the application of plaster to blueboard, the method comprising: applying a skim coat of plaster to blueboard prior to its installation.  
   
   
       2 - Method of  claim 1  wherein the blueboard is placed in an orientation that is advantageous for the application of a skim coat of plaster.  
   
   
       3 - Method of  claim 1  wherein the ambient conditions during application of plaster is controlled to levels that are advantageous for the application of plaster.  
   
   
       4 - Method of  claim 3  wherein the ambient conditions that are controlled include at least one from the list of humidity and temperature.  
   
   
       5 - Method of  claim 1  wherein the ambient conditions that are controlled during the curing of the plaster are controlled to levels that are advantageous for the curing process of the plaster.  
   
   
       6 - Method of  claim 1  wherein the ambient conditions during the drying process are controlled to levels that are advantageous for the drying process.  
   
   
       7 - Method of  claim 2  wherein the blueboard is placed in a horizontal position with the surface to be coated facing up during the coating process.  
   
   
       8 - An improved blueboard product comprising a precoated blueboard with a skim coat of plaster applied to the blueboard prior to installation.  
   
   
       9 - The product in  claim 8  wherein the plaster is applied to the entire surface of the blueboard.  
   
   
       10 - The product in  claim 8  wherein the plaster is applied selectively on parts of the blueboard.  
   
   
       11 - The product in  claim 10  wherein the plaster is not applied to the edges of the blueboard.  
   
   
       12 - The product in  claim 10  wherein a bonding material is applied to areas that are not coated with plaster to facilitate the subsequent application of patching compounds.  
   
   
       13 - The product in  claim 8  wherein a bonding material is applied to the blueboard prior to, during or after the application of pre-coated plaster to improve the bonding of the plaster to the blueboard.  
   
   
       14 - The product in  claim 13  wherein the bonding material is applied to the entire blueboard surface.  
   
   
       15 - The product in  claim 13  wherein the bonding material is applied selectively to parts of the surface of the blueboard.  
   
   
       16 - The product in  claim 15  wherein the bonding material is a mesh material.  
   
   
       17 - The product in  claim 16  wherein the mesh material is metallic.
