Flexible, 2 component gray waterproofing mortar for special applications and demanding waterproofings. Ideal for potable water tank applications.
PROPERTIES: Flexible, and brushable waterproofing mortar of high durability. Its application to potable water tanks ensures the quality and sanitization of drinking water as is certified for that purpose by the State General Chemical Laboratory of Greece (Ref:00178/015/000). The product meets the requirements of regulation EC 1935/2004 Article 28 of the Food and Drinks Code as well as those of German standards “Kunststoffe im Lebensmittelverkehr”, section 1.3.2.5. It provides excellent bonding strength and fully waterproofs the coated surfaces for many years. Due to its high flexibility and strong adhesion, it bridges existing capillary cracks and prevents the appearance of new ones and other shrinkage-related cracks. Its special composition does not allow for the migration of hazardous substances into the water, thus ensuring human health. It provides excellent protection to cementitious substrates to which it is applied, against carbonation and attack by chloride compounds as well as complete protection against seawater. Classified as product for surface protection of concrete surfaces (c) per EN 1504-2 (principal 2/MC/moisture control). APPLICATIONS: APPLICATIONS: HYDROSTOP WATERTANK (PROFESSIONAL) applications are not limited to just potable water tanks. • The product can successfully waterproof surfaces made of concrete, brick and plaster, cement screed, stone etc. • Suitable for crack repairs on floor grouts. • It is also applied on surfaces with high water repellency requirements such as under-ground structures, foundations, tunnels and wet floors as well as structures that are subjected to high hydrostatic pressures (positive or negative), such as basements (exterior application, before backfilling and ‘therapeutically’ in the interior). • It is recommended for use on sloped roofs made of concrete, before installing clay roofing tiles. • It is applied on bridges and athletic or residential pools etc. • It is also recommended for the ultimate roof waterproofing system, protecting lightweight screeds, as part of thermal insulation systems, and generally for the waterproofing of any mineral surface exposed to temporary or permanent moisture. • An additional use of the product is the effective sealing and waterproofing of structures to be planted, such as planters, rooftop gardens etc. In these cases, the product is absolutely superior to asphalt roofing rolls and other various membranes, having as a main advantage that its coatings are applied to the entire surface without seams or joints. Due to its properties, it is the ideal product for inverted roof insulation systems, before the installation NOTES: • For potable water tanks, it is essential to observe hygiene rules (chlorination of water, avoidance of contact with insects, etc.).
of thermal insulation boards. • It is a necessary component and part of the perimeter insulation at ground level (waterproofing zone), when installing the External Thermal Insulation Composite System, THERMOSEAL of DUROSTICK, or any other such system, on wall surfaces close to or touching the ground. USE: Surface preparation: The proper preparation ensures excellent results. Concrete walls: Remove all concrete wood ties, polystyrene as well as all protrusions. Cut all formwork pins and snap ties, 2-3cm deep and coat them with the corrosion inhibitor, RUST FREE POWDER of DUROSTICK. After completion, seal the holes using D-55, DUROFIX, D-11 SUPER FAST or DS-247 of DUROSTICK. Then, clean all surfaces from any loose materials, oils and salts using the biodegradable cleaner, BIO-CLEAN INDUSTRIAL of DUROSTICK. Application: Empty the container with the acrylic emulsion (component B) in a clean container and add slowly, while mixing continuously, the cement mortar (component A). It is recommended to use a low rpm electric mixer, equipped with the ap-propriate mixing attachment. The mixture remains workable for about 2 hours. Apply on well soaked surfaces with an emulsion brush or roller in 3 crosswise coats, with thickness of 1mm each one. The new coat must be applied when the previous becomes walkable or dry to the touch (wall and other surfaces). If the previous coat is allowed to cure, soak the surface again. The product should not be applied at temperatures below +5°C or when there is a chance of rain the next 6 hours. ATTENTION: For absolutely secure waterproofing results and when applying in tanks, first create a curved cement coving around all junctions between floor and walls, and between second and third coat of HYDROSTOP WATERTANK (PROFESSIONAL), apply 20cm wide strips of the fiberglass mesh DS-490 of DUROSTICK.
