Dryseal

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.

• Deep waterproofing through active crystallization
• Sealing of damp cracks up to 0.5 mm
• Significant reduction in concrete permeability
• Increase in the durability of the cementitious mix
• Protection against chemical attacks (sulfates, chlorides, CO₂)
• Improvement of resistance to freeze-thaw cycles
• Restorative action on structures subject to permanent moisture or infiltration
• Reactivation in the presence of new moisture, with permanent protection over time
• Simple and rapid application, even on existing structures
• Water-based single-component product with low environmental impact

• Restoration and protection of new or existing concrete structures subject to moisture or infiltration
• Foundations and slabs
• Retaining walls and underground structures
• Basements and technical rooms
• Underground parking lots
• Concrete tanks and reservoirs
• Structures subject to water infiltration or capillary rising damp
• Civil, industrial, and infrastructural works in aggressive environments

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.

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

The surfaces to be treated must be stable, clean, and free of contaminants that could compromise the correct application and penetration of the product, such as dust, dirt, grease, oils, residues of previous coatings, or surface treatments. Any loose, weak, or poorly adhering parts must be removed beforehand.
In the case of application on substrates isolated from direct contact with the ground or in the absence of natural moisture, the surface must be wetted to saturation with clean water before applying Drykos^® Dryseal, avoiding any standing water or surface puddles.
Excess water must be completely removed and the surface left to dry until it reaches a damp but not wet surface condition. It is recommended to eliminate any standing water at least 24 hours before applying the waterproofing product.

Product preparation

Drykos^® Dryseal 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 must be applied in a single coat using a brush, roller, or low-pressure spray, ensuring an even distribution of the product over the entire surface to be treated.
During application, it is necessary to work the substrate thoroughly to favor the correct penetration of the product into the cementitious matrix and ensure continuous and uniform coverage. It is important to avoid accumulation or pooling of material on the surface, as any excess can lead to the formation of whitish powdery residues; if present, these residues can be removed by simple washing with water.
During application, the treated substrate may show temporary surface darkening, which disappears completely at the end of the drying process.
Drying times vary depending on environmental conditions and temperature: under standard conditions, it is necessary to wait 2–4 hours before allowing foot traffic. Vehicular traffic can be restored 48–72 hours after application. For structures intended for liquid containment such as tanks, reservoirs, or swimming pools, wait at least 7 days before filling.

Cleaning of tools

Tools are cleaned with water immediately after use.

Other indications

• Do not apply on concrete with less than 7 days of curing
• Do not apply outdoors if precipitation is expected within the next 2 hours. In case of rain during application, stop the treatment immediately and resume only after the surface is completely dry
• Do not go over parts already treated, in order to avoid accumulation or excess material
• The product does not require post-application treatments; however, it is necessary to protect the surface from dripping and rain in the first 2–4 hours after installation
• The combined use of Drykos^® Dryseal and Drykos^® Dryseal Ultra increases the durability of the concrete by combining their sealing and water-repellent properties
