Protect and Perfect Your Concrete Countertops

H-SEAL is a water-based, food-safe sealer designed for concrete countertops, sinks, and outdoor surfaces. It penetrates pores to form a protective, water-repellent layer while maintaining a natural matte appearance. With heat resistance and UV stability, it’s built to perform in busy kitchens and sunlit spaces alike. This sealer emphasizes ease of maintenance and long-lasting results, helping you keep surfaces looking fresh after everyday use.

Key benefits you may notice

  • Food Safe & Waterproof: formulated for food preparation areas, it helps keep surfaces clean and easier to wipe down.
  • Heat Resistant: rated up to 392°F, supporting everyday kitchen tasks like handling hot pans and trays.
  • Matte, Streak-Free Finish: delivers a subtle, natural look that resists visible marks and enhances the concrete texture.
  • Long-Lasting Protection: designed for durability under proper maintenance, with performance lasting across years of use.
  • UV Resistant: suitable for surfaces exposed to sunlight without obvious color change.

What you get and how coverage works

  • Coverage varies with surface roughness: typically 5–8 m² per liter, smoother surfaces may require less product.
  • For very smooth surfaces (polished to high grit), expect closer to the lower end of the range; rougher, porous surfaces may reach the higher end.
  • One liter can cover a standard 1 m² area with multiple layers when needed for full saturation.

How to apply (quick overview)

Prepare the surface by cleaning thoroughly and ensuring it’s dry. Apply evenly with a short/medium pile roller, saturating the surface without pooling. Allow 10–20 minutes to dry between coats, then apply 2–3 coats for new work (fewer coats may be enough for maintenance). Plan for a 2–3 hour window between coats and at least 24 hours before regular use. Always test on a small area first and avoid application in rain if outdoors.

Usage tips

  • Maintain a temperature between 8°C and 23°C during application for best results.
  • For outdoor projects, choose a dry spell to minimize weather interruptions between coats.
  • Follow the 24-hour cure period before placing items on the surface to achieve the final strength and finish.
