Should Minwax® Sanding Sealer be used over stained wood?
Sanding Sealer can be used over wood stained with Minwax® Wood Finish Stain or Minwax® Gel Stain but it is not recommended. The purpose of Sanding Sealer is to seal the wood and form a base coat for a protective clear finish. If the wood has been stained, Sanding Sealer is not necessary. Also, it is possible to accidentally scuff the stain when sanding the Sanding Sealer.
