Buying Guide

Choose by substrate

Match primer/sealer to your surface—wood sealers for grain protection, gesso for canvas and mixed-media, and varnish aerosols for finished surfaces

Consider finish and sheen

Select gloss, satin, or matte based on final appearance; aerosol gloss varnish provides a durable shiny topcoat while gesso primes for paint adhesion

Check drying and cure times

Faster-drying products let you work sooner, but longer cure times can improve hardness and sandability for topcoats

Look for durability needs

Choose marine-grade or pre-varnish sealers for exterior or high-moisture wood, and acrylic mediums for flexible, crack-resistant surfaces

Evaluate application method

Aerosol sprays offer quick, even coverage for small projects, while brush- or roller-applied quarts suit larger surfaces and grain filling
