Furniture Surface Preparation FAQs

Why does stain appear blotchy?

Uneven sanding, wood density, filler and absorption differences can create variation. Sample preparation is essential.

Should every defect be filled?

Natural features may be retained depending on design; unstable defects should be assessed before finishing.

Can spray and brush finishes use the same viscosity?

Application method may require different adjustment. Follow the coating supplier’s instructions.
