Sprayed ceilings are very common on commercial jobs where the ceiling structure is exposed.
Sometimes a homeowner wants the same effect. These photos are from an older home in the North/West part of Omaha. The exposed structure was redwood so tannin bleed was a concern. We normally use an oil based product to seal the surface but decided to try a latex product instead. The big plus with using a latex or water based sealer is low odor.
Using the latex product worked but it required 3 coats to lock in the tannin bleed. Fair trade off in my opinion. This room had no windows and ventilation was a concern. Because the homeowner picked a dark color it also required a couple coats of the finish color. We decided to use an exterior grade product for the finish for durability and hide.
When you spray such a large volume of paint in a small area like this there is a dramatic increase in humidity as the paint dries. To combat this we had several fans going. We still had a problem with condensation on the exposed duct work. We would normally turn the air conditioning off before spraying but since it was a typical Omaha summer day we decided to spray the duct work in very light coats and then put the fans on them to speed drying.
Sprayed ceilings can be a challenge sometimes. This one turned out good. Next we will prep and paint the walls and a couple doors and trim. The floor is also getting an epoxy coating.
