You don't glue the fibreglass or silk down, they usually have a slightly tacky backing that helps secure them until you apply the resin. The resin then soaks into the mesh and bonds with the nail. There should be no need for any other product in the application of Silk/Fibreglass nails other than the resins within the system. There are different viscosities of resin, which you would use for stress areas, etc.Would acrylic take to fibreglass? I want thin strong acrylic and thought of laying fibreglass first then applying acrylic. Rather than gluing the fibreglass, would the acrylic substitute?
