Although lead-free paint is the safest option for decking out dwellings, it offers walls little protection from peeping superheroes with X-ray vision. Give supermen some gorgeous interiors to gawk at with today’s Groupon: for $39, you get a two-hour faux-finishing workshop with Harrison Paint of Sterling Heights (a $99 value). Choose from Glaze 101, Metallic Plaster 101, and Textures 101. Classes begin in early May.

The expert instructors at Harrison Paint help hands-on homeowners transform tired walls through small painting classes. Grant walls the glistening garnish they deserve during a two-and-a-half hour Glaze 101 session, which covers the particulars of mixing wall cream with colorants to create a shiny finish, invoking envy in french crullers everywhere. In Metallic Plaster 101, students learn to prep and bedazzle dull domiciles with Mica-enriched plasters, departing class with two take-home sample boards and ample knowledge of aesthetic sparkles. Textures 101, free of drywall mud and its accompanying herds of gleeful pigs, utilizes only professional texture products. Students stencil raised patterns, properly prep walls, and try out trowel techniques ideal for product application.

Small classes max out at eight do-it-yourselfers and are perfect for all experience levels, from retired home-improvement hosts to brand-new brushsmiths. Sessions offer a singular local experience and help wary wallflowers blossom into perpendicular painting pros.
