Staining Tongue-and-Groove Ceilings: Pre-Installation vs. Post-Installation Methods
Because wood expands and contracts with the seasons, the interlocking edges of a tongue-and-groove ceiling can gradually become visible. For optimal appearance, staining should be done before the wood is installed, but if the ceiling is already up, a different technique is required. This guide outlines the materials needed and both procedures.

Stain will seep through fabric drop cloths.
Tongue-and-groove ceilings feature interlocking edges that conceal nails. When finishing such a ceiling, the procedure matters more than the style chosen. Seasonal wood movement causes slight shifts, which can gradually reveal parts of the tongue. For this reason, staining the wood before installation is essential. If you skip this step, the unstained sections of the tongue may later show through, leaving bare wood lines that harm the ceiling's look.
Step 1
Place plastic drop cloths over the floor. Then put fabric drop cloths on top of the plastic.
Step 2
Set the tongue-and-groove boards on the drop cloths. Figure out which face will be visible after installation, and place that side facing upward.
Step 3
Use a tack cloth to wipe down the wood's surface.
Step 4
With a 4-inch paintbrush, apply oil-based stain to the wood, brushing in the direction of the grain. Put on just a thin layer. Let it dry for three hours; if you want a deeper color, add another coat.
Step 5
Rinse the brush with mineral spirits. Avoid water, which can damage the brush.
