Painting Surface
Cement Board
Cement board is a rigid, fiber-reinforced panel used in wet areas; its porosity and factory finish affect how compatible primers and paints bond.
Paint compatibility with cement board
Cement board can accept latex and other compatible coatings when the panel is properly finished, dry, and prepared for the product and intended location.
| Paint | Compatibility | Preparation | Primer or ground | Finish | Guide |
|---|---|---|---|---|---|
| Latex paint | Good on a board approved for painting | Confirm that the exposed face can be painted, finish joints and fasteners as directed, and make sure the surface is clean and dry. | Follow the board and paint manufacturers' requirements for sealing or priming. | Choose an interior or exterior formula suited to the location and moisture exposure. | — |
| Masonry paint | Product-specific | Verify approval for the exact cement board, then repair defects and remove dust, dirt, and loose material. | Use the primer or base coat required by the selected masonry system. | Match the coating to the location, weather, and expected moisture conditions. | — |
