Cleans and Restores Concrete: Effectively cleans and revitalizes concrete surfaces for a refreshed, ready-to-use finish Removes Tough Adhesives: Quickly eliminates newer mastics, layered adhesives, asbestos/black mastic, and stubborn glues, even those over 50 years old High Coverage Efficiency: One gallon covers approximately 100-200 sq. ft., depending on surface texture Low Odor, Low VOC: Virtually no odor with less than 3% VOC; fully GHS compliant for safer use Made in the USA: Formulated with 100% American-grown ingredients for reliable, eco-responsible performance BLUE BEAR BEANedoo Mastic Remover quickly softens and lifts tough tile and carpet mastics from concrete. The low-odor, soy-based formula is made for indoor use with ventilation, helping restore concrete to a clean, smooth surface ready for new adhesive or other finishes. It contains no mineral spirits or petroleum distillates. What it removes: newer mastics, layered adhesives, black (asbestos) mastics, vinyl and acrylic mastics, and old glues. How it works: pour/spread on concrete and allow to dwell until the adhesive softens—about 1–2 hours for black/asbestos mastics and 4–8 hours for vinyl/acrylic mastics. Scrape up and collect. Coverage & cleanup: about 125 sq ft per gallon on horizontal surfaces. After scraping, wash the surface with BLUE BEAR Emerge Cleaner & Degreaser, then rinse with water and let dry before re-coating. Use On: Concrete only. Do not use on wood surfaces. Pro Tips: Protect adjacent wood/drywall with a sand barrier. On porous or cracked slabs, use absorbent (e.g., kitty litter) to help pick up residue. A rotary floor machine on low RPM can assist during degreaser/water cleanup. Perform a residue test by sprinkling water; if it turns cloudy white, continue cleaning until clear.
