Description
Invisible Protective Concrete Sealer for Interior & Exterior Surfaces
Ultralit Matt is a professional-grade, water-based concrete matt sealer designed to protect decorative and architectural concrete without changing its natural appearance. The advanced solvent-free formula penetrates absorbent concrete surfaces to create an invisible, breathable barrier that helps repel water, oil, dirt, and other contaminants while protecting against weathering, frost damage, and colour fading.
Suitable for both indoor and outdoor use, Ultralit Matt provides long-lasting protection for polished concrete, terrazzo, cast-in-place concrete, dry shake floors, paving stones, and other decorative concrete surfaces. Its UV-resistant formulation helps preserve the original appearance of the concrete while reducing maintenance and extending the life of the surface.

Benefits of Ultralit Matt
Ultralit Matt provides long-lasting protection without creating a visible coating or altering the natural look of decorative concrete. Its breathable formula allows moisture vapour to escape while preventing water, oil, and dirt from penetrating the surface.
The invisible finish protects against environmental exposure, helping to minimise staining, frost damage, efflorescence, and UV-related colour fading. Because it does not create a thick surface film, variations in coating thickness remain virtually invisible, making it ideal for decorative concrete where appearance is essential.
Its water-based formulation also makes application simple while providing a safer, environmentally responsible alternative to solvent-based sealers.

Coverage
Coverage depends on the condition and porosity of the concrete surface.
- Coverage: 5–30 m² per litre
Actual coverage will vary depending on the texture and absorbency of the substrate.
Application
Ultralit Matt can be applied to both dry and damp concrete surfaces provided there is no standing water present. For best results, newly placed concrete should be allowed to cure before application, while existing concrete should be clean and free from dirt, laitance, curing compounds, and previous coatings.
The product can be applied using a low-pressure sprayer, roller, or microfibre applicator to create a thin, even coat without puddling. On vertical surfaces, application should begin from the bottom and work upwards using a zigzag motion to ensure consistent coverage.
Once applied, the treated surface should be protected from water for at least 24 hours. Although the coating is dry and ready for light use after this period, maximum water and stain resistance develops over the following seven days.
Maintenance
Routine maintenance is simple and helps preserve the long-term performance of the treated surface. Regular dust removal with a microfibre mop and cleaning with neutral pH cleaning products will help maintain the appearance of the concrete.
Avoid acidic cleaning products, as prolonged exposure may affect the treated surface. Promptly removing spills will further improve stain resistance and maintain the protective finish.
