These bubbles typically form due to improper mixing, application techniques, or the presence of moisture. Here's a step-by-step guide on how to fix them: #### 1. **Assess the Problem** Before starting, determine the extent of the air bubbles. Small, isolated bubbles can be spot-treated, while widespread bubbles may require larger-scale repair. #### 2. **Sand the Surface** If the bubbles are small, start by lightly sanding the affected area with fine-grit sandpaper (around 120-220 grit). Sand down until the surface is smooth, removing any raised bubbles. #### 3. **Clean the Area** After sanding, clean the area thoroughly to remove dust, debris, or contaminants. Use a vacuum or a damp cloth to ensure no particles remain. #### 4. **Reapply Epoxy** Mix a new batch of epoxy, ensuring you mix slowly and thoroughly to avoid introducing air bubbles. You can use a nap roller or for smaller areas, a brush might suffice. #### 5. **Allow Proper Curing** Let the floor cure according to the epoxy manufacturer’s instructions, typically for 24-48 hours. Ensure proper ventilation and temperature control during the curing process to prevent moisture or trapped air. #### 6. **Prevent Future Bubbles** To avoid future air bubbles, ensure that your workspace is free of dust and moisture, and always mix epoxy slowly to minimize the introduction of air. With these steps, your epoxy floor should regain its smooth, durable surface, free from air bubbles.    *TIP:* **Use a Heat Gun During Application**  Another method to remove air bubbles **during application**, gently run a heat gun or torch over the surface. This will help pop any bubbles that form. Be cautious not to overheat, as this could damage the epoxy.     - [Help and Support](https://help.armorpoxy.com/knowledge/help-and-support?hsLang=en#main-content) - [Email Product Support](https://help.armorpoxy.com/knowledge/help-and-support?hsLang=en#email-product-support) - [Contact Support](https://help.armorpoxy.com/knowledge/help-and-support?hsLang=en#contact-support) - [Showroom Visits](https://help.armorpoxy.com/knowledge/help-and-support?hsLang=en#showroom-visits) - [Warranties](https://help.armorpoxy.com/knowledge/help-and-support?hsLang=en#warranties) - [Product Info and Questions](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#main-content) - [General Information](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#general-information) - [ArmorClad: Epoxy System](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#armorclad-epoxy-system) - [Surface Bond: Asphalt & Concrete Coating](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#surface-bond-asphalt-concrete-coating) - [SupraTile: Interlocking Floor Tiles](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#supratile-interlocking-floor-tiles) - [ArmorRenew: Wood & Concrete Resurfacer](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#armorrenew-wood-concrete-resurfacer) - [Job on a Pallet Kit](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#job-on-a-pallet-kit) - [ArmorTallic: Metallic Epoxy System](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#armortallic-metallic-epoxy-system) - [Armor Liquid Membrane](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#armor-liquid-membrane) - [BallistiX: Indoor/ Outdoor Sealer](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#ballistix-indoor-outdoor-sealer) - [Polyaspartics](https://help.armorpoxy.com/knowledge/product-info-and-questions?hsLang=en#polyaspartics) - [Prep And Application](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#main-content) - [Armorclad: Epoxy System](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#armorclad-epoxy-system) - [Surface Bond: Asphalt & Concrete Coating](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#surface-bond-asphalt-concrete-coating) - [SupraTile: Interlocking Floor Tiles](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#supratile-interlocking-floor-tiles) - [ArmorRenew: Wood & Concrete Resurfacer](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#armorrenew-wood-concrete-resurfacer) - [Job on a Pallet Kit](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#job-on-a-pallet-kit) - [ArmorPoxy II: Epoxy System](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#armorpoxy-ii-epoxy-system) - [ArmorUltra: Epoxy System](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#armorultra-epoxy-system) - [BallistiX: Indoor / Outdoor Sealer](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#ballistix-indoor-outdoor-sealer) - [Spartacote](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#spartacote) - [SPGX: Polyurea Coating](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#spgx-polyurea-coating) - [ArmorTrak](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#armortrak) - [A1 VFC Sealer](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#a1-vfc-sealer) - [Floor Repair](https://help.armorpoxy.com/knowledge/prep-and-application?hsLang=en#floor-repair) - [Project Recommendations](https://help.armorpoxy.com/knowledge/project-recommendations?hsLang=en#main-content) - [Garage Flooring](https://help.armorpoxy.com/knowledge/project-recommendations?hsLang=en#garage-flooring) - [Commercial Applications](https://help.armorpoxy.com/knowledge/project-recommendations?hsLang=en#commercial-applications) - [General Issues - Remedies](https://help.armorpoxy.com/knowledge/general-issues-remedies?hsLang=en#main-content) - [Epoxy](https://help.armorpoxy.com/knowledge/general-issues-remedies?hsLang=en#epoxy) - [Liquid Membrane](https://help.armorpoxy.com/knowledge/general-issues-remedies?hsLang=en#liquid-membrane) - [BallistiX](https://help.armorpoxy.com/knowledge/general-issues-remedies?hsLang=en#ballistix) [![Chill listening crop-3](https://help.armorpoxy.com/hs-fs/hubfs/email_template_files/et_black_logo_horizontal.png?width=78&height=24&name=et_black_logo_horizontal.png "Chill listening crop-3")](https://armorpoxy.com/) armorpoxy.com Help Center Copyright © 2026, Armorpoxy Inc
