Oramask 811 and 813 are used with latex paints. 811 is a solid white color (most preferred for etching) while 813 is a translucent blue most preferred for doing painted signs.
Oramask 810 is a specialty stencil vinyl for very smooth flat surfaces and oil based paints. 810S is for oil based spray paint. Both of these have a much lower adhesion than 811 and 813 and should only be used on very smooth flat surfaces and/or with oil based paints.
