I am doing a basement (tape,finish,tex,paint) which the rest of the house has stomp ceiling and sand walls.The stomp has sand also.Spraying sand I am familiar with , stomp I've done a little of.My question is what is the process for doing these two together?My guess would be to stomp ceiling first then spray walls and ceiling with sand.I would like to know if anyone has done this.Also,does anyone prime under the stomp texture?Thanks,I am new here,looking forward to it.
