Joining 2 or more substrates
One of the things you can do with Screen Goo is make screen of ANY SIZE and/or ANY SHAPE. In this case you may need to join 2 or more pieces of a substrate surface – PVC, PCB, MDF, Wood, etc. etc. – in order to make a large single surface.
Remember that Goo is an acrylic paint and does not live well with solvents.
Ensure any compound or any other material that covers the joint between the substrate pieces is NON-SOLVENT-based. Solvent-based materials will come through the paint and will destroy your work.
You will need to make sure that the substance that covers the joint between the pieces has COMPLETELY DRIED and CURED, before applying the Goo.
