Sure Klean Sealer and Coating Remover -- Best Overall
Sure Klean Sealer and Coating Remover by ProSoco is a professional-grade stripper that handles acrylic, polyurethane, and most water-based sealers on horizontal concrete. It is solvent-based and works by softening the sealer film so it can be scrubbed and rinsed away. Apply with a brush or roller, allow 15 to 30 minutes dwell time, agitate with a stiff broom, then pressure wash or scrub away the dissolved film. It is among the fastest-acting products available and works reliably on both thin acrylic coats and thicker decorative sealers. Wear chemical-resistant gloves and eye protection.

Old, peeling, or incompatible concrete sealer must be removed before you can recoat or change products. Applying a new sealer over a failed or mismatched old one is one of the most common causes of bubbling, delamination, and poor adhesion. The right sealer remover saves you from that frustration by cleanly stripping the old film down to bare, porous concrete that is ready to accept a fresh coat. Here are the five best concrete sealer removers in 2026.

Each pick, examined
Sure Klean Sealer and Coating Remover -- Best Overall
Sure Klean Sealer and Coating Remover by ProSoco is a professional-grade stripper that handles acrylic, polyurethane, and most water-based sealers on horizontal concrete. It is solvent-based and works by softening the sealer film so it can be scrubbed and rinsed away. Apply with a brush or roller, allow 15 to 30 minutes dwell time, agitate with a stiff broom, then pressure wash or scrub away the dissolved film. It is among the fastest-acting products available and works reliably on both thin acrylic coats and thicker decorative sealers. Wear chemical-resistant gloves and eye protection.
Citrus Strip Premium Stripper -- Best for Indoor Use
Citrus Strip uses a biodegradable citrus-based solvent that is far less aggressive in odor and fume output than petroleum-based strippers. For basement floors, garages with limited ventilation, or any indoor surface, it is the safest full-strength stripper option. It requires longer dwell times (1 to 4 hours) compared to petroleum products but reliably softens acrylic sealers for removal. It is not effective on epoxy coatings. Apply a thick coat, cover with plastic sheeting to retain moisture, then scrub and rinse when the sealer has softened.
Rust-Oleum Concrete Floor Paint Stripper -- Best for Epoxy and Latex
Rust-Oleum's concrete floor stripper is formulated specifically for the tougher bonds formed by epoxy floor coatings and latex paints, which resist most acrylic strippers. It contains methylene chloride-free solvents that swell and lift epoxy films from concrete without requiring mechanical grinding as a first step. It is available at major hardware chains, making it the most accessible option for epoxy removal. Always test in a small area first -- on some older epoxy systems a second application is needed for full removal.
Prosoco Sure Klean 600 -- Best for Heavy Buildup
Sure Klean 600 is a heavy-duty acid-based cleaner designed for concrete surfaces with multiple layers of old sealer, curing compounds, or calcium deposits. For concrete that has been resealed several times over years without full stripping, the combination of Sure Klean 600 for initial heavy-layer removal followed by the standard Sealer and Coating Remover gives the most thorough prep. It also removes efflorescence, rust stains, and mortar residue in the same pass. Follow the manufacturer's neutralization instructions carefully before applying any new sealer.
Klean-Strip Adhesive Remover -- Best for Spot Removal
For small problem areas -- an edge that did not bond, a section that is peeling, or a test patch before committing to full stripping -- Klean-Strip Adhesive Remover is the practical choice. It is available in quart sizes at hardware stores, dissolves acrylic residue quickly, and rinses clean with water. It is not the right choice for a full-floor stripping job, but for targeted prep or touchup work it is faster and less wasteful than buying a full gallon of professional stripper.
Buying considerations
What to consider
The most important variable is the type of sealer you are removing. Acrylic and polyurethane sealers respond to solvent-based and citrus strippers. Epoxy requires a stronger formulation. Penetrating silane and siloxane sealers do not form a removable film and do not need chemical stripping. Identify your sealer type first with the xylene test before buying a stripper. For indoor use, prioritize low-VOC and low-odor products. For large exterior areas, a professional-grade solvent stripper and a pressure washer will deliver the fastest results.
What to consider
After stripping, inspect the surface for damage before resealing. Our [best concrete sealer for old concrete](/articles/best-concrete-sealer-for-old-concrete) guide covers the top products to apply after stripping an aged surface. For stubborn staining that remains after stripping, our [best concrete sidewalk cleaner](/articles/best-concrete-sidewalk-cleaner) article covers effective cleaning solutions. See our [testing methodology](/methodology) for how we evaluate all products.
Questions answered
Apply a few drops of xylene (paint thinner) to the surface. If the sealer softens and becomes tacky, it is solvent-based acrylic. If water beads on the surface and the sealer does not react to xylene, it is a penetrating silane or siloxane sealer -- these generally do not need removal, just a light recoat. If the surface is hard, clear, and neither xylene nor water affects it, it is likely an epoxy or polyurethane that requires a stronger stripper or mechanical grinding.
Pressure washing alone rarely removes film-forming sealers -- it can remove loose or peeling sealer edges but cannot chemically break the bond of intact acrylic, epoxy, or polyurethane films. Use a chemical stripper to soften the coating, then pressure wash or scrub to lift it. A surface cleaner attachment and 3,000 PSI pressure washer makes final cleanup significantly easier after chemical treatment.
