SignPly is available in 12.5mm & 17.5mm with a paintable surface on one side (F1S) or paintable on both sides (F2S). The difference between the two is that the F2Sproduct has a yellow ochre coloured resin impregnated paper on both sides for double sided signs. The F1S product is for single sided signs. It has a black sealer on the back specifically to help keep moisture out.
The sealer paper is unsuitable for painting as it has no adhesion qualities. The yellow ochre paper is compatible with all paint systems but to ensure durability it is always advisable to use a high-quality system and applied according to the paint manufacturers specifications.
SignPly must be edge sealed with a good quality paint system to keep water from entering the plywood substrate. In doing this it will ensure that the sign will last for several years. Panels can be sawn, drilled and routed with all standard woodworking tools.
