Prime Exposure Retarder is a surface-applied chemical retarder designed specifically for creating high-quality exposed aggregate finishes in concrete by delaying the surface set time, allowing you to wash away the cement paste and reveal the underlying stone.
Key Features
- Application suitability – Ideal for horizontal concrete surfaces such as driveways, walkways, patios, and decorative slabs.
- Exposed aggregate effect – Uniformly retards surface cement paste to reveal clean, well-defined aggregate texture.
- Controlled set time – Provides predictable delay to the surface set, giving ample time for washing and finishing.
- Ease of use – Simple brush, spray, or roller application to fresh concrete with no special equipment required.
- Consistent results – Formulated for reliable, repeatable exposure depth across the entire treated area.
- Versatility – Suitable for a wide range of mix designs, aggregate sizes, and decorative concrete applications.
- Clean removal – Washes off easily during the exposure process, leaving no residue that could affect sealing or long-term performance.

Prime Exposure Hydrochloric Acid is a powerful cleaning and etching solution designed to prepare concrete surfaces before sealing or coating. It removes stubborn contaminants and opens the concrete’s pores, ensuring superior adhesion and long-lasting finishes for both new and existing slabs.
Key Features
- Application suitability – Ideal for use on bare or unsealed concrete surfaces in residential, commercial, and industrial settings.
- Cleaning – Effectively removes dirt, grime, laitance, and light surface contaminants to restore a clean substrate.
- Etching – Chemically etches the concrete surface to create a uniform, textured profile for optimal coating bond.
- Surface preparation – Prepares concrete for sealers, paints, epoxies, and other coatings by improving penetration and adhesion.
- Effectiveness – Fast-acting formula delivers consistent results with minimal dwell time when used as directed.
- Versatility – Suitable for driveways, patios, garages, workshops, and other concrete areas requiring pre-coating treatment.
- Professional results – Helps achieve a smooth, even finish and enhances the performance and durability of subsequent coatings.

Safety Note: Always handle hydrochloric acid with care. Use appropriate PPE, including acid-resistant gloves, eye/face protection, and suitable clothing; ensure adequate ventilation, follow dilution and application instructions, and keep out of reach of children.

Prime Exposure Xylene Solvent is a professional-grade solvent formulated for thinning, cleaning, and reactivating concrete sealers and coatings. Ideal for contractors and serious DIY users, it helps restore, maintain, and fine-tune solvent-based decorative and protective finishes on concrete surfaces.
Key Features
- Application suitability – Designed specifically for use with solvent-based concrete sealers, coatings, and decorative finishes.
- Thinning – Effectively reduces the viscosity of compatible sealers and coatings for smoother application and improved penetration.
- Cleaning – Quickly dissolves and removes uncured or fresh solvent-based sealer residues from tools, equipment, and surfaces.
- Reactivation – Softens and reactivates existing solvent-based sealers to help repair whitening, roller marks, and lap lines.
- Fast evaporation – Rapid flash-off supports quicker turnaround times while minimizing solvent entrapment issues.
- Versatility – Suitable for use on driveways, patios, paths, and other decorative concrete and exposed aggregate surfaces.
- Professional results – Supports a uniform, high-quality finish with improved clarity, gloss, and overall sealer performance.
