ASK YOUR PROPARTNER Paint tips for basement walls, floors and celings Should we paint the basement floor? Rick Watson, Product Information The SherwinWilliams Company 22 PPC Winter 2013 It is important to make sure that the floor will accept a paint film. If the floor tends to have moisture coming up through the surface, then painting would not be recommended. Even if you feel that the floor is dry, we recommend that you test for moisture by taping a few pieces of 3-mil plastic (2 by 2 foot square) to various areas of the floor. Make sure that the tape seals the plastic on all sides so no air can get between the plastic and the floor. After 48 hours, inspect for moisture, discoloration, or condensation on the concrete or the underside of the plastic. If the area under the plastic stays dry, then painting the floor should be okay. Prep is also very important. Remove all form release agents, curing compounds, salts, efflorescence, laitance, and other foreign matter. If the floor surface is previously painted, make sure it is clean, dry and dull. Apply coatings to a test area to ensure you have compatibility and adhesion. For smooth, hard or glossy coatings or bare concrete that is glossy, the surface should be dulled by abrading. If the paint is peeling badly, complete removal will be necessary. A good choice for such surfaces would be water-based acrylic floor enamel or water based concrete stain. An upgrade for durability would be water based catalyzed epoxy designed for floors. The product you use depends on the use of the basement. I need to paint a new dry basement, both walls and textured ceilings. The owner's dogs will live down there most of the day. What should I use? First, I would make sure everything is clean, dry and in sound condition. Remove all form release agents, curing compounds, salts, efflorescence, laitance and other foreign matter. The walls should be dry with no signs of water intrusion. On new concrete walls, I would suggest a Sherwin-Williams product called Water Blocking Primer/Finish with odor-reducing properties. This product helps 1) seal the interior bare concrete walls from exterior moisture intrusion and 2) reduce common household odors. It may be used as a primer/finish or, to maintain the odor-reducing benefits, it can be topcoated with Harmony Interior Acrylic Latex Paint finishes. As far as the texture ceilings, I would turn to Harmony Interior Flat. This product also has odorreducing properties. The length of time these products actively reduce odor depends on the concentration, the frequency of exposure and the amount of painted surface area. I too have dogs and they spend the day in the basement. These products are ideal for this type of project. PPC Got a paint question for Rick? Email yours to: More project solutions at
