Can brick slips be used on plasterboard

We are often asked where our brick slips can be used and one of the most commonly asked is can they be attached to plasterboard. There is no problem with sticking our deco and Cottager range directly to the  plasterboard you may want to PVA the board prior but this is not always required a far better option if it is possible is to use a tile backer board this is more rigid and designed to take tiles which is basically what a brick slip is also it is generally produced using a cement based product against the paper of Gypsum board
