Featured Project Tuck-Under Garage Finishing in Maple Grove A homeowner in Maple Grove wanted to finish a dark, tucked-under garage space that was currently unusable. The room featured bare cinder block walls, a single electrical outlet, and a stained concrete floor. The client envisioned a clean, livable extension of their home, complete with space for a television and comfortable vehicle access. Our team managed a comprehensive interior build-out, handling framing, insulation, electrical additions, and floor coatings to update the space. Key Takeaways THE CHALLENGEThe raw garage lacked insulation, adequate electrical outlets, and a functional overhead door opener. THE COATINGWe applied six coats of a glossy acrylic sealant to the floor and installed full drywall. THE RESULTA bright, finished garage featuring an updated door system and a polished concrete floor. Finishing a tuck-under garage requires treating the space with the same care as an interior basement. We prioritized proper insulation and electrical distribution before sealing the environment with drywall and protective floor coatings. Project Summary Client Profile: Residential Homeowner Project Location: Maple Grove, MN Primary Objective: Convert a raw cinder block garage into a finished space. Coating System: High-gloss acrylic floor sealant and black ceiling paint. Key Outcome: A fully insulated, well-lit garage completed with a six-coat floor finish. Assessing the Raw Tuck-Under Garage The garage was unfinished, consisting of cold cinder block walls and a damaged concrete slab. Rusty steel support beams ran across the ceiling, presenting an aesthetic and functional challenge for the build. With only one electrical outlet, the space couldn't support basic tools, lighting, or the client's desired television setup. Furthermore, the low-hanging steel beams prevented us from using a traditional ceiling-mounted garage door opener. Drywall, Insulation, & Floor Sealing We started by framing all the exterior walls and installing dense insulation to regulate the temperature. Our team then hung and taped the new drywall to create a smooth interior shell. To handle the ceiling constraints, we painted the rusty steel beams black and installed a specialized wall-mounted garage door opener. "We framed it all, insulated it, did all the drywall, and then painted. The overall effect is a night and day difference." - (Troy, Mudslingers Drywall & Remodeling) For the flooring, we applied six consecutive coats of a clear, water-based acrylic sealant to the original concrete. Due to high humidity, we allowed 48 hours of curing time between each coat, building up a reflective, durable surface finish. Project Progress Functional Garage Space Results The tuck-under garage is now a well-lit environment capable of serving as a functional workshop or entertainment area. The new electrical outlets provide ample power, and the wall-mounted opener operates the new garage door efficiently. The six-coat acrylic floor finish masked the original concrete damage, leaving a clean, easy-to-maintain surface. The dark painted beams add an architectural contrast against the fresh drywall, finalizing the 2.5-week project. Ready to Finish Your Garage?

Yes, we frame directly over cinder block walls to add proper insulation and hang smooth drywall. This process improves the room's energy efficiency and aesthetic appeal. How long does it take to apply an acrylic floor sealant? Applying a multi-coat acrylic sealant requires patience. We typically apply up to six coats, allowing 48 hours of curing time between each application, especially in humid conditions. What is a wall-mounted garage door opener? A wall-mounted opener, or jackshaft opener, is installed beside the garage door rather than on the ceiling. This is an ideal solution for spaces with low clearance or structural steel beams blocking the overhead track.
