RetroPel™ is an oil and water repellent specifically formulated for concrete and terrazzo floors. It prevents oil from penetrating the floor and water reactions that cause whiting. Newly densified and polished concrete floors remain susceptible to water and oil penetration because the densification process has not been fully achieved. During the densification process, the crystalline growth continues for up to 12 months. RetroPel has been formulated with advanced, water-based fluoropolymers. These small molecular structures allow for maximum penetration. It is not a topical sealer, but rather, a penetrating sealer that fills the microscopic gaps in the floor’s crystalline structure. It does not change the appearance of the floor.

RetroPel Benefits
Water Repellency
Protects surfaces from spills and stains.
Microscopic Gap Sealing
Penetrates and fills tiny gaps in the floor for a long-lasting protection.
Water Reaction Shield
Prevents water whiting on newly densified and polished floors.
No Visible Change
Maintains the natural appearance of your floor.
Effortless Application
Easy, stress-free application; reduces applicator fatigue.
No Burnishing Required
Does not require burnishing to cure.
Universal Compatability
Ideal for all Ashford Formula and RetroPlate treated floors – new or old, standard or colored – and all concrete and terrazzo.
RetroPel Application
Read all instructions and SDS information before use.
Use appropriate safety equipment. Always test floor surface for suitability and desired results before overall application. Evaluate vapor transmission or other potential concerns. Let surface dry thoroughly before inspection and approval.
Preparation
- Protect people, vehicles, property, plants, and all surfaces not meant for treatment from product, residue, splash, fumes, and wind drift. Use polyethylene or other proven protective materials.
- Ensure fresh air entry and cross ventilation during application and drying.
- Remove any dirt, oil, grease, paint, waxes, efflorescence, and surface sealers before application.
- For best results, clean the floor with CreteClean Plus with Scar Guard™ using an auto scrubber with blue or black pads, or a mop and bucket.
- RetroPel can be applied 28 days after placement of the concrete.
- Surface & Air Temperature: Between 40–80°F (4–26°C).
- Equipment: Pump-up sprayer with adjustable conical tip (approximately 0.5 gpm), microfiber pad, propane burnisher and soft natural hair burnishing pad (optional), and appropriate safety equipment.
- Coverage: Averages approximately 600–1,200 ft²/gal (15–30 m²/L). Most floors densified and polished to 800-grit or higher yield 900–1,000 ft²/gal (22–25 m²/L). Coverage depends on concrete porosity, level of polish, and application method.
Standard Application Procedure
- Stir well before and during use. Do not shake (shaking causes excessive bubbles and foam).
- Mask off and protect baseboards or adjacent areas to avoid splashing or overspray on unintended surfaces.
- Liberally apply an even coat of sealer with a pump-up sprayer. Allow product to soak in and work it in with a microfiber pad until the floor is fully saturated.
- If the first application is immediately absorbed, apply a second application wet-on-wet before the first dries.
- All product should penetrate the concrete—do not allow it to dry on the surface. If excess product dries, buffing can remove haze.
- Do not walk on the surface until completely dry. Avoid standing water for at least 24 hours. Full cure is achieved in 24 hours.
- After application, rinse and flush all equipment with clean water.
Maintenance
- Do not use acidic detergents or detergents containing sulfates or hydroxides.
- Use CreteClean Plus with Scar Guard in scrubbers or mop buckets for best results.
- Keep the floor clean by removing dirt and debris regularly. Clean up spills promptly.
RetroPel FAQs
How is RetroPel different from a topical sealer?
Unlike topical sealers that sit on the surface, RetroPel penetrates into the floor’s microscopic gaps, forming a durable internal barrier without adding gloss or changing the look of the floor.
When should RetroPel be applied?
RetroPel can be applied 28 days after the concrete has been placed and once it has been densified and polished. It’s especially effective during the first 12 months when densification is still ongoing.
What surfaces is RetroPel compatible with?
It’s suitable for all concrete and terrazzo floors, including those treated with Ashford Formula and RetroPlate, whether new or old, standard or colored.
Does RetroPel affect the appearance of the floor?
No. RetroPel does not alter the floor’s appearance, sheen, or color. It leaves the surface looking the same but with enhanced protection.
Do I need to burnish RetroPel to cure it?
No. RetroPel does not require burnishing to cure. The product cures fully within 24 hours without any additional steps.
How do I maintain a floor treated with RetroPel?
Use CreteClean Plus with Scar Guard for regular maintenance. Avoid acidic cleaners or those containing sulfates or hydroxides, and clean up spills quickly to preserve repellency.
