Sto Primers

Prepare any type of substrate prior the application of Sto finishes and coatings.

Sto Primers can be used for priming prepared concrete, masonry, plaster, continuous insulation systems, base coats or drywall surfaces prior to application of Sto finishes and coatings. Available in both sanded and smooth textures, Sto primers promote uniform substrate absorption and can help maintain proper dry film thickness. In many instances, they can also lower your overall costs by extending topcoat coverage.
