Clean any dust or contaminents off the floor. If it is fairly smooth and even, then you can apply the DPM direct to the sub floor. If it is a bit rough or pitted you will need to lay a smoothing compound first. Make sure that you use a moisture tolerant compound, an acrylic latex such as F. Ball Green bag and stopgap 114 liquid. The DPM will need to be covered with a smoothing compound. Prime the cured membrane with P131 neoprene primer, again from F.Ball, allow it to dry fully and then apply a product called Stopgap 800 smoothing underlayment. Once dry this can be sealed or painted. It is designed as a wear coat. Most of the other smoothing underlayments are designed to be covered with a flooring. Hope this helps.
