before using pegagraf hydro
Apply on a dry, clean and degreased substrate.
Glossy and satin surfaces should be roughened up previously.
When repainting surfaces protected with Pegagraff Hydro, first an adhesion primer in Pegalink has to be applied.
Not painted metal substrates such as steel, aluminium, stainless steel, cupper etc. have to be treated with a suitable paint before applying Pegagraff Hydro.
