Its fast-setting, low-VOC and low-odor formulation combines the performance of traditional polyaspartic technology with a safer, more environmentally responsible water-based system. Ultra Seal MAX provides a refined satin appearance while enhancing the depth and intensity of the underlying pigments. Key Properties 100% Solids · Water-Based Solvent-free, water-based technology designed to combine professional polyaspartic performance with reduced odor and lower environmental impact. Aliphatic & Non-Yellowing Excellent UV stability helps maintain appearance and resist yellowing when exposed to ultraviolet light. Fast Return to Service Approximately 1 hour dry-to-touch and approximately 4 hours before light foot traffic under specified application conditions. Satin Finish Creates an elegant satin-look surface while enhancing pigment depth, intensity and color saturation. Chemical Resistance Designed to resist oils, solvents and aggressive substances without visible surface damage. Low VOC & Low Odor Suitable for projects where reduced odor, occupant comfort and lower environmental impact are important. 2-Component System Part A Base Component Primary resin component of the Ultra Seal MAX two-component polyaspartic system. Part B Activator Component Activator component mixed with Part A immediately before application. Mix Ratio: Combine Part A and Part B at a 1:1 ratio. Pot life after mixing is approximately 20 minutes, so only prepare the amount that can be installed within the available working time. Available Sizes & Coverage 0.5 Gallon Kit ~200 ft² Approximate coverage 1.5 Gallon Kit ~600 ft² Approximate coverage Coverage is approximate and may vary depending on substrate condition, surface profile, porosity, application technique and material thickness. Recommended Applications Microcement Floors High-performance final protective layer for professionally installed decco decorative flooring systems. Decorative Walls Protective satin finish for decorative wall surfaces requiring increased durability and cleanability. Residential Projects Suitable where a low-odor, durable and refined protective finish is required. Commercial Projects Fast-setting properties help reduce downtime on professional commercial installations. Sensitive Environments Water-based and low-VOC formulation is well suited for areas where reduced odor and environmental impact are valued. UV-Exposed Surfaces Aliphatic, non-yellowing formulation provides excellent UV stability and gloss retention. Application System Step Process 1 Make sure the underlying decorative surface has been properly prepared and is clean, dry and ready to receive the sealing system. 2 Apply 1 coat of decco Eco Seal Matte and allow the surface to properly seal before applying Ultra Seal MAX. 3 Combine Ultra Seal MAX Part A + Part B at a 1:1 ratio. Mix only the quantity that can be applied during the approximately 20-minute working time. 4 Apply Ultra Seal MAX uniformly using a microfiber or short-nap roller (3/8"–1/4"). 5 For larger areas, a flexible rubber squeegee combined with a roller may be used to increase application speed and help achieve uniform coverage. 6 One coat of Ultra Seal MAX is specified as sufficient to achieve the waterproofing performance described by decco. 7 A second coat may be applied when maximum waterproofing protection is desired. 8 Allow approximately 1 hour dry-to-touch, 4 hours before light foot traffic, and approximately 24 hours for full cure.

Maximum Protection Designed as a premium protective topcoat within the decco decorative surface system. Faster Project Turnaround Rapid curing allows light pedestrian traffic in approximately four hours. Enhanced Color Satin finish intensifies underlying pigments, producing greater depth and color saturation. Professional Finish Provides a clean, uniform satin appearance designed for demanding residential and commercial surfaces. Important Installation Notes Recommended System: Apply Ultra Seal MAX over 1 coat of decco Eco Seal Matte for optimal performance. The satin topcoat may slightly deepen and intensify the appearance of the underlying pigment. Installer Tip: Ultra Seal MAX has a short working time. Organize the installation area, tools and crew before mixing Part A and Part B. Work continuously and maintain a wet edge to help achieve a uniform professional finish. Professional Use: Application conditions, substrate preparation and proper mixing directly affect final performance. Always review the current decco Product Data Sheet before installation.
