Dryseal Ultra

Drykos® crystallizing technology is distinguished by its efficiency through a chemical reaction with moisture and the by-products of cement hydration. This process generates, within the pores, capillaries, and cavities of the concrete, an insoluble crystalline complex that prevents water penetration. This complex becomes an integral part of the concrete mass, ensuring its resistance to water and aggressive chemical agents from any direction, promoting restoration and protection, imparting waterproof properties, and increasing its durability and service life.

• High repellent action against water, fuels, oils, and aggressive chemical agents
• Active waterproofing in both positive and negative pressure
• Continuous chemical resistance in a pH range between 3 and 11
• High resistance to chloride and sulfate ion penetration
• Increased concrete durability in highly aggressive environments, such as marine contexts, wastewater treatment plants, and structures subject to de-icing salts
• Anti-dust effect with consolidation of the treated surface
• No alteration of the substrate’s aesthetic appearance
• Improved resistance to freeze-thaw cycles
• Crack sealing capability up to 0.5 mm
• Preventive action against the formation of moss, algae, and biological vegetation
• Water-based formulation, non-toxic and low environmental impact
• Certification for suitability for contact with drinking water

Drykos^® Dryseal Ultra is suitable for the protection, waterproofing, and increased durability of new or existing concrete structures, particularly in the presence of water or chemically aggressive environments. It is used in:

• Foundations, slabs, and retaining walls
• Underground parking and underground structures
• Tanks, reservoirs, and water containment structures, including potable water
• Wastewater treatment plants and sewage works
• Marine works and structures in coastal environments
• Bridges, viaducts, and infrastructure subject to de-icing salts
• Industrial flooring and concrete surfaces exposed to chemical agents
• Structures subject to freeze-thaw cycles
• Exposed concrete surfaces, both in civil and industrial applications, where a penetrating, non-film-forming, and long-lasting protective treatment is required

The product has a verified Environmental Product Declaration (EPD), compliant with ISO 14025 and EN 15804 standards. It contributes to credits in LEED v4/v4.1 sustainability protocols, specifically the MR credit – Building Product Disclosure and Optimization (EPD), supporting the achievement of up to 2 total points. The product is also consistent with the requirements of the Minimum Environmental Criteria (CAM) for construction, promoting environmental transparency of materials and use in sustainable public procurement.

Color

Colorless after application.

Appearance

Liquid.

Storage

12 months from production date.

Storage conditions

Store correctly in the original, sealed, intact packaging, protected from frost and direct sunlight, at temperatures between +15°C and +35°C. Higher temperatures could deteriorate the product. Low temperatures could cause partial crystallization of the product; in this case, shake the package manually and store it in warm environments.

Theoretical consumption

~ 0.2 L/m2

Yield

~ 5 m2 per 1 L

Diluent

Ready-to-use product.

Application temperatures (substrate and environment)

Minimum +5°C | Maximum +35°C

Substrate preparation

Application on New Concrete

The surface to be treated must be brushed and cleaned using compressed air to remove dust, processing residues, and loose particles. Subsequently, it is necessary to wash with a pressure washer to ensure complete cleaning of the substrate. Application of Drykos^® Dryseal Ultra must be carried out on a dry surface.

Application on Existing Concrete

Before application, it is necessary to remove any contaminants such as grease, oils, release agents, or other substances that may compromise adhesion and product penetration, using suitable detergents or systems.
Once the substrate has been cleaned, proceed with the same preparation required for new concrete.

Product preparation

Drykos^® Dryseal Ultra is a ready-to-use product and must not be diluted. Thoroughly homogenize the product by manually shaking the sealed container before application.

Application

Drykos^® Dryseal Ultra must be applied in a single uniform pass by spraying with a low-pressure pump or with a brush, ensuring complete and uniform coverage of the surface to be treated. The product must be distributed continuously, avoiding pooling or accumulation and ensuring proper saturation of the substrate.
The product can also be applied as a second pass on surfaces previously treated with Drykos^® Dryseal Ultra. The combined use of the two products enhances the restorative and protective action of concrete, promoting pH increase in deteriorated areas and contributing to slowing or stopping reinforcement oxidation phenomena.
After application, the treated surface must be left to dry for approximately 1 hour at a reference temperature of 24°C before being put into service; at lower temperatures, drying times may increase by 1–2 hours depending on environmental conditions.
The product must not be applied on surfaces with temperatures below 5°C and the concrete must have reached a minimum curing time of at least 7 days. It is also necessary to avoid application in the presence of imminent rain or on frozen substrates.
Immediately after treatment, the concrete may exhibit temporary surface darkening, which disappears completely when the product dries. In case of excessive application, slight whitish halos may appear on the dry surface; such residues can be easily removed by simple washing with water.

Cleaning of tools

Tools are cleaned with water immediately after use.

Other indications

• Do not apply the product outdoors if rain is expected within 2 hours of application.
• In case of rain during application, immediately stop work and wait for the surface to dry completely before resuming treatment.
• Surfaces already treated and in the drying phase must not be re-coated.
• Do not apply on frozen, overheated, or surfaces exposed to strong direct sunlight.
• Avoid pooling or excess product; any accumulation may generate surface halos.
• Do not dilute the product and do not mix with other materials not expressly indicated.
• Protect glass, metals, and non-absorbent surfaces during application.
