\nBrushable, elastomeric waterproofer that combines water soluble polyurethane resins modified with specific acrylic dispersions. Apply the product to create a seamless membrane without seams nor joints, that is impervious
\nto water and provides excellent roof protection. Certified by the University of Athens
\n(Department of Physics, Division of Applied Physics), as \u2018Cool\u2019 material of low thermal conductivity and high reflectivity in the visible spectrum at a rate of 93%. It reduces the energy related costs for heating and cooling and significantly improves the energy efficiency of buildings. During the summer months it reduces the interior temperatures of the spaces below the roof surface. During the winter months it presents zero water absorption and maintains the roof surface dry.
\nClassified as product for surface protection of concrete
\nsurfaces per EN 1504-2.<\/p>\n

\nHYDROSTOP-PU is suitable for waterproofing roofs, terraces, parapet walls, gutters, gypsum boards,
\nas well as properly installed and well adhered asphaltic roofing rolls.<\/p>\n
\nUsing a roofing scraper or a wide chisel, remove all deteriorated sections, if any. Continue by using a hard, street type, broom. If any moss, lichen or grease stains are present, remove them by using D-95 CLEANER of DUROSTICK, or a bleach-water solution at a dilution ratio of 1:1. scrub the surface thoroughly and rinse with
\nplenty of clean water. Surfaces to be waterproofed must be dry and should not get wet for the next 48 hours, in order to avoid surface moisture from being trapped.<\/p>\n
\n\u2022 Detached torch-down roofing materials: Remove them using a wide roofing scraper and roofing torch or other mechanical means.
\nWell adhered existing torch-down roofing materials, only require to thoroughly remove all the dust from their surface and to seal any detached sections.
\n\u2022 Detached or deteriorated elastomeric waterproofers, have to be removed using a wide roofing scraper or a razor blade.
\n\u2022 Detached elastomeric materials that are not visible, can be found using a garden hose. Pour water on the roof surface from about 1 meter high and listen carefully. Notice the change of the sound the water makes when it hits the detached parts of the waterproofing and mark them. Cut the detached sections using a razor blade, a scraper or other mechanical means. Scrape the defective material off.<\/p>\n
\nUsing a roller and a brush, prime the surface using the water soluble, micromolar stabilizer AQUAFIX or the SOLVENT BASED PRIMER diluted 50% with THINNER 101 of DUROSTICK. Alternatively, dilute the product by adding 30% water and prime the entire surface. Once the primer has been absorbed into the surface and is completely dry, it is possible for some hairline cracks to become visible. Treat those cracks by applying several coats of HYDROSTOP-PU, until they are completely sealed. Each new coat is applied once the previous one is dry. Seal wider cracks (\u2265 1mm) using the elastomeric sealant DS POLYMER or by using the polyurethane elastomeric sealant DUROFLEX-PU of DUROSTICK. Once the sealant is dry, apply 2 or 3 coats of the polyurethane waterproofer HYDROSTOP-PU over the sealed cracks. Complete the waterproofing process by coating the entire area with 2-3 crosswise coats, to cover any minor substrate imperfections. Apply each coat 6-18 hours after the previous one was applied (depending on ambient conditions) or once the previous coat has completely cured and it is walkable.<\/p>\n
\n\u2022 Mix well before use
\n\u2022 Waterproof all vertical surfaces around the roof (parapet walls), their entire height
\n\u2022 Avoid exceeding thicknesses of 0.5mm per coat
\n\u2022 Low ambient temperatures delay the final curing time while high ambient temperatures speed up the curing process
\n\u2022 Avoid applying the product in high humidity conditions or when there is possibility of rain within the next 24 hours.
\n\u2022 After curing, the product is harmless to health and the environment.<\/p>\n
\nClean all tools with water (and soap or detergent if necessary), immediately after use.<\/p>\n
\n\u2022 Minimum consumption: 0.75lt to 1.2lt\/m2 for 2 coats, depending on the substrate
\n\u2022 1.2lt to 1.5lt\/m2 for 3 coats, depending on the substrate (long-lasting protection)<\/p>","protected":false},"excerpt":{"rendered":"
