Applying Wood Conditioner

Wood conditioner is especially beneficial for softwoods or unevenly grained woods, as it helps to promote an even stain application. Here are the steps for application:

• Select a Conditioner: Choose a pre-stain wood conditioner that is compatible with your stain type.
• Application: Using a clean brush or cloth, apply a thin layer of conditioner evenly across the surface.
• Waiting Period: Allow the conditioner to penetrate for about 5-15 minutes, then wipe off any excess. Follow the manufacturer’s instructions for specific timing.

Final Preparation Steps

Once your wood is clean, sanded, and conditioned, there are a few final steps to ensure optimal results:

• Inspect the surface for any imperfections or rough spots and sand again if necessary.
• Ensure the workspace is free of dust and debris, as these can settle on the wet stain.
• Confirm that the temperature and humidity levels are suitable for staining (ideally between 50°F and 90°F).
