Smoothing a deck before re-staining

Single grit. The whole deck. Done before lunch.

A deck doesn't need a four-stage climb. One grit, a 5" random orbital or a pole sander, and a strategy for the edges.

The climb

The exact sequence, in order.

    Knock down splinters and remove old stain

    ROS on the boards, pole sander for the edges. Sweep before you stain.

Watch out for

The things that quietly ruin the job.

  • ·Don't go finer than 100. Smoother decks shed stain faster — you want pores open for absorption.
  • ·Sand the edges of the boards too. Stain pools where there's a sharp edge unsanded.
  • ·Wait 24-48 hours after sanding if humid — let any raised grain show before you stain over it.

Questions people ask

The practical part.

Should I pressure wash first?

Yes, and wait at least 48 hours. Wet wood gums up the abrasive instantly.

What about pole sander vs ROS?

Pole sander is faster for the flats; ROS is gentler and cleaner. Pick by deck size.
