Nevertheless, some of the Drylok paint like Drylok-extreme or Drylok pro can be sprayed according to the manufacturer. To spray drylok you can follow the rest.

Choose a spray:

Better if you do not spray thick paints. The nozzle of the sprayer has to be large. Otherwise, the paint will clog and will not come out.

Apply the coats:

Apply a thin coat of paint. You can either use a sprayer machine or brush. Fill up all the holes. Then spray a second coat. You do not put the sprayer too close to the surface and keep that moving. Also, look for places where paint can not reach. Apply the coat evenly and let it dry.

The first layer should always be a thin one that covers up holes. Any imperfections should be covered up with this coat. The second is the perfect finish on the surface without exposing the marks and holes.
