Whatever surface you would normally paint with any virgin low-luster latex paint, you can use EcoCoat on. There are some applications that EcoCoat is not recommended for, like walked-on surfaces or direct-to-metal applications. EcoCoat is produced in 14 original colours (The Parkland collection) and 12 secondary colours (The Nautical Collection); so, colour selection is limited and mixing EcoCoat colours together to create secondary colours should be left up to you. Minor colour differences from one batch to the next may happen, so, always purchase enough of one colour from the same batch to finish their entire project.
