Understanding Sandeply Plywood

Plywood selection has become tricky with all the grade options, core types, and finish qualities flying around. As someone who has used plywood for every application, I got hands-on with sandeply and when to use it. Today, I will share it all with you.

What Is Sandeply?

Probably should have led with this part honestly—sandeply (sanded plywood) is among the most popular choices in construction and woodworking. Both faces are sanded smooth for a finished appearance.

Characteristics

That’s what makes sandeply endearing to us woodworkers—its versatility:

• Both faces sanded for smooth finish
• Available in various thicknesses (1/4″ to 3/4″)
• Multiple wood species options
• Takes paint and stain well

Common Uses

• Cabinetry: Interior panels and backs
• Furniture: Visible surfaces requiring finish
• Shelving: Smooth surface for easy cleaning
• Underlayment: Smooth base for flooring

Grades

• A-grade: Highest quality face, minimal defects
• B-grade: Slight imperfections, still paintable
• C-grade: More defects, typically for hidden use
• D-grade: Utility grade, structural use only

Selection Tips

• Match grade to application visibility
• Consider core type for structural needs
• Check for voids and delamination
• Higher grades cost more but finish better

Working with Sandeply

• Use sharp blades to minimize tear-out
• Support large pieces to prevent breakage
• Sand lightly before finishing
• Apply primer before painting
