What should I do if my resin peels off concrete?

Why Does Resin Peel Off Concrete?

Resin coatings are designed to adhere tightly to concrete. When resin begins to peel, it’s usually due to dust, moisture, grease, or other contaminants left on the surface prior to coating. Sometimes, using the wrong type of primer, or skipping the priming step altogether, can also result in poor adhesion and premature peeling.

How to Fix Peeling Resin on Concrete

• Remove all loose resin: Begin by scraping or sanding away any flaking or delaminated resin. Ensure the entire area is free of loose sections.
• Clean the surface thoroughly: Use a degreaser and rinse well to remove all dust, oils, or contaminants. Allow the concrete to dry completely before proceeding.
• Apply an appropriate primer: To promote strong adhesion for the new coat, select a dedicated concrete primer such as Epoxyprimer, which is water-based, odourless, and suitable for both professional and DIY use.
• Recoat with a suitable resin: Once primed and fully dry, apply a suitable concrete resin such as Resinstone or a polyurethane finish for extra durability.

When This Matters

Addressing peeling resin is especially important in driveways, garages, or outdoor paths where regular use and exposure to weather demand a tough, well-bonded finish. Early intervention can prevent moisture damage and help avoid more costly repairs in the future.
